For anyone having issues with the WieldSword functionality, it's good to know that I didn't show how to edit it to include an animation, but it is the same as the UnWieldSword, so if you want to add that animation make sure to also include an event dispatcher (Call onWieldSword) from your enemy blueprint, and update the task to only Finish Execution when OnWieldSword is dispatched (Just like we did in the SheathSword from 40:45 to 44:20)
@@djtc2093 here I'm referring to the wieldSword task in the behaviour tree, because a lot of people had issues with this, and almost everyone forgot to call finish task (with success true) ONLY when the onWieldSword event is dispatched
can you please add the files for this tutorial please? (if you still have the proj files that is)...still heaving problem with it, after i followed your instruction for debugging the WieldSword functionality
BTW, the problem i had, was in the SheathSword and WieldSword tasks...i was connecting the finish execute to the bind event instead to the finish custom event respectively in both tasks
These are seriously the best tutorials I've come across. No fluff, great pacing, and even though they're over 40 minutes long each, I know they're worth watching bcz you do such a good job explaining everything, and it's not filled with useless information like modeling a character first, or animating something, straight to the point and topic of the tutorial. Thanks for all your hard work making these AI tutorials, they couldn't have come at a better time for me since I'm implementing a combat system right now. You've definitely earned a subscriber.
Hey! Thank you soo much for this comment. It really keeps me motivated when I see that my content is this helpful to people, so thank you for appreciating the effort that went into this 🙏🙏
@@AliElZoheiry I'm a game designer with 25+ years of experience working in various proprietary engines and I'm learning UE for the first time. I cannot thank you enough for putting this video together! Teaching this old dog some new tricks! 🤣🏆🎉
Your tutorials are absolutely insane and I really enjoy watching them. You really find the right balance of digging into topics, tempo and - my personal highlight - level of coding quality. Looking forward to see and learn more from you!
You have by far the best, cleanest, most to the point and easiest to follow tutorials I've seen on here. This is helping me resolve a lot of little things I wasn't quite sure about in behavior trees. Now I finally know the RIGHT way to use them.
Thank you so much for your kind words! I'm really glad to hear that my tutorials are helping you out with behavior trees. Your feedback means a lot to me! If you have any more questions or need help with anything else, feel free to ask.
This has really helped me alot I was so scared to get into making ai but you have made it so clear and easy to follow I still dont understand ai but I understand more than I did so thank you so much! I'll be sure to credit you when I make my game!
Hi, Ali. I am learning so much from your tutorials. I do have one suggestion. Make sure that what you are referring to is visible on the screen. There are many instances where what you are typing is cut off. This is true whether it is in the window or full screen. Thank you for the hard work on these tutorials. This is helping me understand AI.
Thank you, I indeed noticed this in a few other videos, In my latest 2 videos I started only zooming on important details which would otherwise be too small on screen, so hopefully this issue isn't happening anymore
Thank you soo muchhhh!! im a C++ developer and making a stealth game, sadly the ai documentation is very bad and usually i take the Bp logic and translate to c++ in a optimal way. You r awsome!
Yeah the documentation for C++ is quite lacking, I will be making some C++ tutorials as well soon because some systems are only available in C++ so stay tuned ;)
Learned so much from the firs episode of this series. I didn't know anything about behaviour trees and after watching the first episode and then practising on my own I am a lot more comfortable with it. Thank you Ali you are my Unreal Sensei, keep up the excellent work :)
Starting this series after completing load and save system which was fantastic. You teaching style is amazing - problem and solution based which i found very helpful in learning process. Just leaving this comment to encourage you to produce more videos in more series especially in multiplayer system login using facebook/google, messenger style chat using dedicated server , and save and load in multiplayer system. Keep up the good work man . Cheers 🎉
Hey, thank you so much for your kind words and suggestions! I really appreciate the support and I'll definitely keep your ideas in mind for future videos. Cheers! 🎉
I like that the way you design these, you are using best practices for how you would set it up for an actual game. Most tutorials just focus on getting it functioning superficially for the purpose of the video.
Thank you for your comment! I really appreciate it. My goal is always to make sure the tutorials I create are not only functional but also designed with a real-world game development approach in mind. I'm glad you noticed that! 🙏
Thanks for the tutorial series. Very clear and easy to understand. I got stuck for atleast a day trying to move from the "set movement speed" to the "Move along patrol route" stage. Watched the video over and over and couldn't figure it out, added loads of print screens and got nowhere... It turned out that I used a selector instead of a sequence for the patrol state... FML :D onto Episode 3!
Im a complete noob and managed to follow this great (yet complexed) tutorial.. I kept leaving comments asking for help but then would follow the logic from what I asked and debug.. Then comment again with a new problem and delete as it changed aha. This is my final comment to say thank you.. Most my issues were to do with leaving a box unchecked or not connecting a pin for example I hadnt connected WeildSword to execute Bind event in the BTT_weildSword and in Sheathe sword so the BT wasn't finishing the task and getting stuck haha.. Having the comments to read through definitely helped me to fill in gaps on parts I had missed or you had done outside of the edit. Thanks for another great tutorial. Took me about 4 hrs as a noob to troubleshoot my mistakes :)
Hey, thanks for sharing your journey with the tutorial! It's really great to see how you were able to troubleshoot and solve the issues on your own. Your perseverance definitely paid off. Glad the comments were helpful, and I'm happy you found the tutorial useful. Keep up the great work!
I've only been building BluePrints for about 3 weeks and I was able to follow along easily with a few minor debugs needed for my own errors. Thanks for the great work and I look forward to watching the next one in your video list!
That's great to hear! I'm very happy this was beginner friendly as well. The aim for this series is to be beginner friendly while still teaching intermediate and experts a lot of new things.
Amazing tutorials! Learning a lot in here. You just got yourself a new patreon! Can't wait to continue the rest of the tutorials! Keep up the good work!
Thank you so much Twidie 💖 really glad that you are finding my content helpful, and i'm really grateful that you joined my Patreon. I appreciate you 🙏😇
this episode ruined it for me bro, everything was going amazing until this episode, about 3/4ths through the video things began not working right with the enemy, after the whole sheath thing. i followed exactly and went over things three times to ensure no node is incorrectly done, i can see a LOT of others had issues here too, i went on after this video and the other videos are good but this one is the issue one, i know you've defended your edits and actions in the comments but this video seriously desrves a re-do, but go over things completely as you do them, this is the ONE video hurting this entire playlist.. i found this video on reddit, on the UE sub there was about a dozen users who praised the tutorial but warned against part 2 of it, which i ignored because i assumed that i could figure out where they had issues, looks like it got me too, this video is mostly good but had a vital error keeping it from being as polished as your other vids, please re do it bro.
DUDE yes!!!!! I found this on reddit yesterday too but not on that sub, it was from the game devs sub, u/NoFrillaz or whatever shared it but told people to skip the second video because he skipped a lot of steps later on in the vid and it messes up a lot of ppl lol I've been trying to redo things 4 times now and have the exact same issue!!!! it makes me so angry because everything else is SO good!! but darn it
me too I am having trouble with it around that part , my enemy freezes and jitters when supposed to be switching, I agree I wish he can remake it, please Ali
yes bro it was all good until this one, its hard to explain to him about what mine does but reading all the other comments i can see everyone that has issues with this vid, hasthe exact same issue because mine is doing same and it just make me frustrated and i've rechecked everything, please ali it won't take much effort to just redo this one, it will make ur playlist perfectly i've done the following 3 videos after this one and they all are good but the issue on this video has roots that lead and branch out to the after vids.... i've redone this tutorial 3 times now because of this issue, thinking i missed something but no, it's literally all from the sudden addition of nodes later on, even if u mentioned a few changes at the start that doesnt gloss over things, just please redo it in full and show things as you mention them!!! @@BadNewsStudio
i'm having issues too, with the wield sword function part, i know he pinned a comment with a solution but that doesn't quite resolve things in full. i'm hoping for a re-do too haha, i've been stuck on this video for 4 days now
Hey all, just to be clear, there is nothing wrong with the tutorial, you can follow it from start to finish without any problems. The reason I wrote this comment, and the reason you might be having issues, is that event dispatchers, and behaviour trees are a new way of working for most of you, so it can be confusing, but I assure you, the content itself is tried and tested and works perfectly, if you are having issues, feel free to join the Discord server and we have a youtube-help channel there where you can ask your question, provide details, then I or someone else can help you there. Just make sure first to check the existing questions in case you find the solution you're looking for. Good luck 🤞
Thank you teacher Ali. Like part 1 your tutorial are very detail moreover your teaching and how you explain are really amazing. I also consider WieldSword function that didn't show in video as homework. Even now I cant count the spline point and don't know why it need to -1. The Spline point function are the last thing that I cant understand. Also it took me nearly 2 month to understand overall how the function operate, That make me realized how I lack of the foundation [Gonna cry in corner]
for example you have 10 spline point in your patrol spline point index 0 = spline point 1 ... ... ... spline point index 9 = spline point 10 index as defaulf start 0 but your point of number going 1 , 2 , 3...
Hey there! Thank you so much for your kind words and for sharing your thoughts. I appreciate your dedication to understanding the concepts. Don't worry, taking your time to fully grasp the material is commendable, and it's okay to take a bit longer to fully understand everything. Keep going, you're doing great! 🙏 P.S, checkout the response from @DaviesMurphy, it sheds light on how incrementing the spline point works! Thanks for that Davies
Loving my journey through these tutorials... I stopped right before the end and was going to add another decorator for "IsFocused" and got hung up a bit... clicked play and 2 seconds later you went into the focus fix 🤣
Thank you so much for the kind words! I'm glad to hear you enjoy my teaching style. 🙏❤️ Unfortunately I know nothing about making VFX, very far away from my software engineering background
Hi Ali , im really excited about the series . Im just bum out that sometimes i dont understand your math, especially the Patrol Index. Im trying my best to understand it, had to crush my head. Hopefully ill knock some sense into my own brain :D
Hey Danny, let me try to explain it simply. The patrol index is just the point on the spline that the enemy is currently on starting at 0 (meaning the first point) so when the enemy moves to the next point we need to add 1 to that index (so then the patrol index is equal to 1 which means the enemy is at the second point in the spline) then we need to check if we reached the end of the spline, by checking if the index is equal to the number of points in the spline (but minus 1 because we started at 0 not at 1) then if we reach the end we just start subtracting 1 from the patrol index instead of adding 1 (this we change the direction to be -1) and do the reverse once we reach point 0 on the spline again. Hope it makes more sense now
For anyone having issues about being stuck in A state of flip-flop, hence not being able to change states. The problem might be the keyboard key. You can try using the enhanced input system. I first had a problem with the "Tab" button, but when I used it with the enhanced input actions, the problem was solved.
I have a problem with patrol system , chasing and attacking is perfect but patrol is not working properly sometimes enemy stops suddenly and the patrol happen only once he does not repeat it by getting back to same starting point . I assume that the problem is with my landscape, as I am using a desert landscape it has many up's and down's i think this might causing problem but again sometimes character travels the end point even spline is under landscape but again not returns he just wait there.
Hey! That sounds like a tricky issue. It could definitely be related to the landscape’s elevation. Make sure to check both your spline's setup and the logic for returning to the starting point in your patrol behavior. If the spline is under the landscape, it may not trigger properly. I recommend adding some debug prints to see where the issue comes from. Hope that helps! 🙏
I was stuck for many hours (using 5.4) that the enemy did not unsheath the sword and just stood still. The fix was to change the play rate in the first Play montage to -1. Because the animation is set to -1.
I'm sorry, I am having trouble assigning the patrol route spline to my character. I can't find any linkable parameters in my BP_Enemy_Base to the spline and your Video is blocking the view at 8:50 Any clues? Great tutorial btw!!! Congrats!!!
Hey Erik, so the "PatrolRoute" variable we created in the enemy class should "Instance editable", which means you need to click on the "eye" icon next to the variable name in your blueprint, or make sure the checkbox for "Instance editable" is checked. Then when you select on your enemy in the World. You can search for that variable in the details panel and assign it the value of your patrol route (which also has to be placed in the world first)
So a few things...I'm going to hang with this but you move a little too fast and I think you forgot to show what you did around 41:00 regarding the changes you made to the initial Weird Sword. But so far I'm liking it.
Hey, thanks for your feedback! I indeed didn't show the changes to the WieldSword, because they are exactly the same as the SheathSword event, and I showed the event in the blueprint, so you can pause and see what's happening there if you'd like
Really great stuff here! I've been following along trying to do everything here but with State Trees. Would love to see some future content on handling AI with State Trees. Any chance you've got plans to tackle that topic?
Hey there! Thank you for the kind words and suggestion! I've actually been considering doing a series on AI with State Trees, as it's a popular request. Stay tuned!
This zooming in and out all the time is making me seasick. The quality of the sound and video is great you dont need to do all the zooming. Awesome tutorial series, learning a lot!
Hey Kasper, thanks for the feedback, I did indeed realize that the zooming was unnecessary and stopped doing that in the later videos of the series. Glad you're finding it useful ☺️🙏
I'm asking you a question through a translator because I'm Korean, but I don't know if you can translate it accurately. I have two questions. 1. When the game goes on, the character immediately pulls out the sword, puts it back in, and moves to the spline point. When the game goes on, I want the game to move right away instead of pulling the sword out and putting it back in. How do I fix this? (Solve: Weild Sword was applied to Beginplay.) 2. I've never solved a non-soft animation with a character movement either, is there a way to go to the line instead of spline point? (solve: It was solved when I changed 'use controller rotation yaw' to false. However, if you change the function to false, the character will look in the opposite direction when you press the '2' key. So, in bp_enemybase, 'Set Controller Rotation Yaw' is set to true at the front of FieldSword and false at the front of SheathSword. Also, in bp_enemybase (Self), the default value of 'Set Controller Rotation Yaw' is set to false. Through this method, the original value works as false, true when the knife is taken out, and false again when the knife is moved. I don't know if this is the right method, so if you have a problem like me, please try this method and verify it.) + If the next motion does not occur after drawing the sword, check 'Call On Field Sword' is connected to On Completed in 'Wield Sword'. It took me an hour to find the problem..😂 I've found a solution, but I won't erase it to present a solution to someone with a problem like me.
Thank you for your detailed explanation and providing solutions to your own questions! It's great that you've found a method that works for you. Your willingness to share your process to help others is really admirable. Keep up the problem-solving spirit!
you are really best, im deleted my old ai system in only BP and im trying to use now BT. You are best man and you are best man again and you are best best man. Change your channel name to "BEST MAN"
Thank you so much for your kind words and support! I'm really happy to hear that you found my content helpful as you transition to using behavior trees. I appreciate your enthusiasm and encouragement!
I just have a question, I want to have a box that spawns the monster when the player collides with it, but when I do that and spawn the monster, it doesn’t have a patrol route selected and I don’t know how to make it come with a patrol route already set. Btw I am spawning a new ai and setting it to the enemy when the box collision happens, it does everything except follow the patrol route if that helps.
Hey there! In order to have the monster spawn with a pre-set patrol route, after spawning it, you will have a reference to the spawned character. Then you can just get the PatrolRoute variable from that reference and set it's value to be the reference of the patrolRoute from your level (you will have to get a reference to that patrol route first though, and how to get that reference will depend on how you built your game)
OMG, I rewatched the video three times now because some things weren't working correctly and every time I forgot to set the succeed boolean to true in the finish execute note...
I'm finally up to speed on this video, got everything working, the only issue I am having is with the enemy attack when I am really close. The way it starts is on attack, They focus and run at me to attack, but then when I get really close, the enemy stops turning, and instead, will start attacking in the direction they were looking at until I separate myself with enough distance for them to turn towards me. I tried messing with the "Move To Target acceptable radius "which did help a little, but even at "0" they still wont turn when I am really close. Does this get covered later on, or maybe there is someway to make sure the enemy will always rotate towards me before attacking? This isn't a huge deal, I can always fix this later on for my project. Anyways, thanks for the vid! Cheers! 🙌
Hey there! Thanks for your feedback, I'm glad you're finding the video helpful. It seems like the issue you're facing might be related to the way the enemy rotation is being handled. I'd suggest checking that in the base enemy pawns character movement you have "Use controller desired rotation" set to true. Hope that helps and best of luck with your project! Cheers! 🙌
@@AliElZoheiry Thanks for the response, yeah I have "use controller desired rotation" set to true, the enemy just didn't want to turn when I was really close to them for some reason so I did mess around with some settings to see if I could fix it. But yeah, everything seems to be working now because in part 4 video the enemy is given a "strafe" in the BT so now they strafe around me while in attack which is perfect. I know you get a lot of comments on this series but I really do appreciate all the help! 🙏
Great content so far! My AI has been severely lacking. And, these videos are just what I need. I'm wrapping up for the day. I've only had one issue that I cannot seem to figure out. When I press "1" the first time, everything works great, and I created an UnsheathSword Montage similar as you did, and spawn the sword using a Montage Notify as usual when working with Notifies. But, the Enemy will not turn to face the Player as it unsheathes the sword. It will unsheath, then turn to the Player everytime. I've tried playing around with different things, and I'm not quite sure what is going on. Other than that everything looks great. I've debugged the AI Behavior Tree, and it looks like it flashes by the BTT_FocusTarget(with AttackTarget as the Attack Target Key) and goes directly to the BTT_UnsheathSword I created under the BTD_IsWieldingSword Decorator. That is all within the first sequence. The numbers on the nodes look correct. I'm not sure why it is skipping the BTT_Focus Target Task though. EDIT: For now, I'd just added a Wait 0.5 Seconds Node to the middle of the sequence. So it will Focus wait half a second, then unsheath the sword. This gives the AI enough time to turn and face the player, even if directly behind the AI. Using 5.2.1, but don't think much has changed in this regard.
Thank you! Glad you've been enjoying the content If your AI is taking a long time to turn it could be the rotation speed of the enemy character is slow. If you're not using the default manny character and default settings, make sure to match it to the default manny settings for rotation speed and see if it helps
@AliElZoheiry - Thanks for the tip! I was actually thinking the same thing when I woke up this morning. Oftentimes, I wind up waking up with a proper solution XD Just got in from some morning endurance cycling. I'm going to get going on my projects in a half hour. And, this will be the first thing I test. Adjusting the turning/rotation speed on the ai mesh.
@@Dominicn123 - Sorry. I never did figure out the issue with the enemy not facing the player. I just left in the Wait half a second node to the AI Tree which I mentioned above. At this point I think I'm running off a copy of one of Alizoh's source files I downloaded a while back. I didn't think of looking for the change in the source for that particular issue. When I downloaded the source project, and started working off of that.
thank you for your efforts brother. my main language is not english. Selam in Turkey. I solved my problem. Press " 1 " not moving npc. Solution in " BT_Enemy_Base " > BTT_SetMovementSpeed > Movement Speed (in right) > Spritting. Not Idle :) I hope it was helpful :)
In part 1 we built the "BP_Enemy_Base" code (pt 1: 37:00 - 41:07). But it looks like that code got replaced by completely new code, of unknown origin, appearing here in this Part 2 at 8:16. I've spent a week on this tutorial. I've redone this and part 1 a few times now, and I can't get it working. Here's how mine works: Press "1" the first time: Enemy just stops patrolling and stares at me. Press "1" twice: Enemy slides along his patrol zone and continually unsheaths Press "1" third time: Enemy slides, then finally runs and attacks me. Press "1" fourth time: Enemy sheaths a few times and returns to his Patrol Path; the sword never disappears. After tearing out most of my hair, I gave up and downloaded the project zip. When I open that project and play, the Enemy AI faces me, unsheathes, and then runs behind a wall, faces the wrong way, and swings at empty space a few times. Is there a way to get a project download at the point where the action makes sense at the end-point of this video?
Hey Heavenseek, so the enemy blueprint was not completely replaced with something else, as mentioned at 1:14, I just changed the WieldSword event and behavior tree task to include an animation and an event dispatcher, which I proceed to explain at 38:20. It sounds like your problem is likely with the wield sword event and behavior tree task, make sure that in the WieldSword event you dispatch OnWieldSword and in your task you bind to this event dispatcher and only call Finish Execute then, just like we did for the unwield task at 43:55
@@heavenseek Hey man, I found a bug in the engine that might be causing your issue. It happened to me today when I restarted the engine, I found that the Blackboard keys on the "BTT_MoveToIdealRange" in the tree got reset and I had to manually select them again. Meaning that I had to Change the "IdealRadius to be either the AttackRadius or the DefendRadius (depending on whether I'm attacking or strafing) and the AttackTarget set it to AttackTarget as well. Hope this helps
This is exactly what is happening to me. I followed the directions exactly and have gone back through them several times. I can't see where the discrepancy is. I'll take a look at Ali's suggestions here.
This is probably a specific problem I had but an easy fix anyway, my set focus wasn't working so the AI didn't focus on the player before drawing the sword, then I found out that I set the AI rotation settings to Orient Rotation to Movement instead of Used Controller desired Rotation.
Im pretty new to this whole UE world but at 32:32 where you cast to the AIController couldn’t you just add the AIC as a Component in the Components Menu to gain access to all its variables and stuff?
Hey! Indeed that is of course possible, but this is just part 2 of the series, things get a lot more complex as it goes on. This is only done to ease people into the topic
Hey! if you don't see the increment function, then you are probably trying to call it on the wrong actor reference, make sure you have the right reference to the BP_PatrolRoute to call the function on it
I am trying to apply Walk Patroling to my Enemy, but instead of only Walking, some points Enemy is Walking and some points Enemy is Running, Its doing both. Any suggestion.
Hey! If you're points are not evenly spaced out, then the enemy might be accelerating faster and slower depending on your acceleration speed and ground friction and deceleration settings in the character movement component. These all affect how fast your enemy moves
Hey, thanks for the tutorial, everything is working fine now. However, i faced 2 problems and i want to share them in case anyone is facing the same issue. Problem-1. The BTT_WieldSword function in the behavior tree was running endlessly and sword was not being equipped. I rewatched the video again to find the solution. Solution : The notify name on the animation montage should be same as the switch on name function in BP_Enemy_Base. Problem-2: The SheathSword function was not working properly. Solution : I forgot to do one step. I had to go into BTT_SheathSword function and from the as BP enemy base drag out a node and search for bind event on sheath sword, this will automatically create a custom event for you as shown in the video. And connect your custom event to finish execute. You have to do this for both sheat sword and wields word functionality.
I'm using ue5.4 and i have an issue where when i hit the 1 key it will not switch over to attack state. After an hour i tested my keys using a string to call hello and that was not working either. Can someone tell me whats going on with my keys?
Hey, no idea honestly, if you're print string on key press didn't work, then it sounds like you got a problem with your engine itself, because there's nothing specific to get input keys to work. just double check your setting the right key and try different ones. also restart the engine or install a different version
My Enemy is Patroling only 1st point of the spline after reach that point Enemy starts idleing and not patroling anymore. I cant understand what am I missing.
The more better way instead of using a Interface or Cast is to Store Data in ActorCOmponent , this is a great feature using which we not only make Less Coupled things but also modular things
Hey Brock, thank you for the feedback. I indeed use actor components heavily later in the series when I start integrating a damage system and attack system
@@AliElZoheiry I see, that's great then and btw I loved your end result that's why I started watching, if you could make a enemy which can predict player moves like attack, flank
I followed the steps, but right at the beginning, when the simple test is performed to follow the path, mine stops right at the starting point and doesn't move forward.
45:58 When I press 1, the enemy just runs towards me and uses the Sword_slash montage, but the montage_Sheath_Sword and montage_Unsheath_sword animations don't work, even the BP_sword sword doesn't appear, I checked and followed everyone's comments but still not successful, is there any way, please help me
1. Make sure that you are connecting the skeletal mesh to the montage 2. Make sure there is no typo in the montage notify name 3. Make sure you are using a Montage notify and not a regular notify in your montage asset 4. Make sure you pulling the switch off of "Notify Begin" pin in your play montage node
Hello Great Tutorial, I had a problem where i couldnt change the movement speed for the enemy player. It really took me a long time to find my problem: at 19:35 he added the "max walk speed", i mistakenly added "max movement speed". cheers
Hey, thanks for your comment! I'm glad you enjoyed the tutorial and identified the issue with the movement speed. It's great to hear that you were able to troubleshoot and solve the problem. Happy coding! 🙌
Hi Ali! Your tutorials are awesome and really help me, but I have a problem when the enemy puts away his sword, he starts doing it endlessly. I did everything right. I redid it a few times, but nothing changed.
Hey! Thank you for your kind words 🙏 Regarding the issue with the enemy endlessly putting away the sword, it sounds like you are ending the task before the Sword is actually put away, so double check the montage notify spelling, and that the switch statement coming out of the play montage node is coming from "OnNotifyBegin" and also check that you're correctly binding to the sheath sword event in the behaviour tree task correctly
Followed this almost 100% and tried to use the instruction on sheath sword to also create and unsheath and it just gets stuck in the behaviour tree in the first branch of the wield sword line...
Common mistakes are: - Typo in the montage notify name (either in the montage or the switch statement off of the play montage node) - You used the wrong type of notify (regular notify instead of montage notify will not work) - You are not pulling off of the NotifyBegin in your play montage node (before the switch statement) - You are not binding correctly to the event dispatcher
Thank you so much for your kind words! I'm really glad to hear that you're enjoying the videos. If you have any specific topics or requests, feel free to let me know. Happy learning!
Seems like I can't have multiple enemies near eachother when I have any of them patrolling. I assume that's covered in a later tutorial but I just finished #4 and didn't see a solution yet. Any suggestions?
Not sure what you mean by having multiple enemies near each other. If you mean that you want multiple enemies to use the same patrol route, then you will need to store the current point on the patrol route in the enemy instead of in the patrol route blueprint (so that it's unique per enemy instance)
@@AliElZoheiry I’ll try that, thanks! And for whatever reason when I had a patrolling character and an idle or wandering character within sight range they would both freeze. (With two wandering enemies it mostly works)
Hi Ali, amazing video as usual, always top tier videos, thanks for your knowledge!! Quick question: i implemented a patrol route for one of my maps, and i spawn allies who will travel through it regularly (moba style). They should go from index 0 to last index, BUT all get assigned the same single patrol route and the patrol index number keeps changing each time i spawn one, so they do not follow 0 -> 1 -> 2 - > ... last index. Is there any way to have them kind of have their own instance of the same patrol route? Thanks in advance and please keep up all the amazing work you do !
Hey there! Thank you for your kind words and for reaching out. This tutorial assumes one patrol route per enemy, not multiple enemies following the same route. The main difference is that the PatrolIndex (which we increment when the enemy moves to the next point) is stored on the BP_PatrolRoute itself, therfore multiple enemies can't share it, because when one moves, the index increments and the other enemy will also read that same variable and move to the same point as the first enemy. To have the patrol route support multiple enemies, you need each enemy to store their own PatrolIndex route, and increment their own copy of that variable
These videos are great! I find myself stumbling through UE5, how did you get to the point where you could build behavior trees, tasks and functions on the fly?
Thank you! I'm glad you're finding the videos helpful. Building behavior trees, tasks, and functions became easier with practice and experimentation. I recommend trying out small projects to gradually build your skills and confidence in UE5. Keep experimenting and learning - you'll get there!
Hey there, sorry to hear you're having issues. I suggest debugging the behavior tree to see what node is executing when you press "1" (by looking at the tree while the game is running)
If you still need help you might just need to check inverse condition on BTD_HasPatrolRoute in the Behavior tree but, that's only if your issue was the passive not working
im getting a strange issue where when my mannequinn model tries to attack, the frame before he swings he looks another direction away from the player then plays the attack animation facing the player, its only a split second but noticable. not sure if this is due to an animation issue or if the behaviour tree is setting the AI to some other state and its causing that. Any suggestions would be appreciated! thank you :)
i have a feeling its to do with the animation and nothing to do with this tutorial.. perhaps something to do with root motion settings... :( its very strange, the mannequin seems to rotate the same direction just before the attack animation and is always the same direction so depending where im standing in relation to him it can look quite bad he does a 180 sometimes for a split second before attacking
He's probably losing the focused target for some reason during the attack, I suggest adding a breakpoint in the flow and seeing at which node it starts failing
is there any way like without having pressed 1 the enemy goes patrolling and then when in range attacks the player cause in the video 1 is being pressed to change states of enemy is there any other way round ?
In the behavior tree tasks that you create you are casting to the enemy base class. Do you think it would be more efficient to either update the BBkey through the enemy blueprint by using "get ai controller>get blackboard>set blackboard value as..." OR would it be better in the behavior tree to cast only once and store the enemy reference instead of casting every created task?
Once we start adding the enemy AI interface, I won't be casting as often since I'll be calling interface functions, but in general, casting isn't a performance heavy operation, so you can cast on each tick, hundreds of times and it won't be a performance issue unless it's thousands of times per tick
Anyone else having issues with "get spline point as world position" at 12:49? I can't get that. Edit. NVM After UE5 Crashing it had not saved the function in BP_PatrolRoute
Thanks for these awesome tutorials! I do have one issue with the Blackboard Decorator that is on the CombatState Selector. With it on, the enemy only runs the PassiveState side of the BT. With it off, the enemy will try to move to AttackTarget, but slingshots around the area never actually reaching the player. I don't know what the issue is, but any insight would be much appreciated.
I'm not really sure I understand the issue, but if it is regarding the decorator not succeeding/failing correctly, then I suggest checking the implementation of the decorator and seeing when it returns false/true. Otherwise, some common mistakes are: - Using "Selector" when you mean to use a "Sequence" node - Setting the wrong input parameter to a decorator or task
Excelent Video, I have a doubt, in my case my character when he appears on the map makes the animation of drawing his swords, but I want him to not move while he is doing it, so I put a wait at the beginning of the Passive State, it worked but then to advance point o'clock it is also expected, do you know how to make the wait only at the beginning and not repeat itself anymore, thank you.
If your character is doing an action and that action is triggered by a behavior tree task, then you shouldn't Finish the task execution until the action has ended, that's why I added the event dispatcher in the wield and sheath sword functions, to tell the task that the animation is over and you can move to the next node. This is what you should do as well, because a wait node won't work for all animations since they have different timings
Hey! It sounds like you might be looking in the wrong spot. Make sure you are trying to call the function on the correct actor. If it doesn't exist it means you are pulling off of a wrong actor type
Thank you, your tutorials are amazing! But unfortunately I can't solve the problem in one place - In the behavior tree the logic always gets stuck after BTT_Wield_Sword or (when pressing "1" again) BTT_SheathSword. Could you please tell me where I could have made a mistake?
You know what, I was having exactly the same issue and I found the solution : You need to follow exactly the same process that you did for "BTTSheathSword" task, meaning bind the Event to On Wield Sword at the end before Finishing execute :) (referenced step for the Sheaf in min 49:24 of the tutorial)
@@camillemjx9674 Thank you for your reply! But if you're talking about the 44:20 moment, I've already done it in both BTT and got just that, the character picks up the weapon and just stares at me. ( Or when I press 1 again, he hides it and stands there).
Hey Depreska, if the task itself get's stuck (meaning that it get's activated and never ends) this means that you aren't calling "Finish execute" with success = true in your behavior tree task. Either that, or you're montage notifies aren't being called when playing your wield/sheath montage animations. Make sure that you connected the Switch node in the montage from "OnNotifyBegin" and not off of any other pin, and also make sure that your notifies are named correctly in your montage and don't have any typos
@@AliElZoheiry Thank you! Unfortunately, I was just inattentive, and did not connect the Call On Wield/Sheath pins in BP_Enemy correctly, instead of “On Completed” I connected it to the topmost one. >_< Time to start learning during the day instead of at night. ('''')(^_^)('''') Thanks again!
Amazing tutorial. I do have a small problem. When the enemy reaches one of the spline points it waits for halve a second and then continues to move again, but it doesnt smoothly continue as shown in your video. Any idea why this is happening?
It could be the character movement settings you have are different, things like acceleration and friction can affect the movement of your character. I am personally using all the default settings that come with the UE mannequin (except the things I changed in the tutorial)
Hello. In the video at 32:40, you add "Cast to AIC_Enemy_Base". When I press 1, it stops right at this Node. The cast simply fails. What could be causing this? Thank you
@AliElZoheiry buddy my AI whenever reaches the point of the spline it slows down and almost stops for a 0.1- 0.2 sec, is it possible to nake the movement smooth so that it won't stop on these points and rather run smoothly through the spine
The AI stops because the MoveTo task finishes and there is a slight delay till the next one (but it definitely shouldn't be 0.1 -0.2 seconds, more like 0.05) if you are experiencing a longer stop that what I have in my example, try playing around the the deceleration values on the characterMovement component (things like deceleration speed, ground friction, acceleration speed, etc..) If you want it to be completely smooth, then you'll have to start the next MoveTo task before the enemy reaches the next point on the spline, meaning that you have to check when the enemy is "almost" at the point, and then start to move to the next one
I cant get the keyboardevent 1 key to work. i have gone over everything you have done for 1 hour and its all the same? yet i cant do it? any help please
Hey there! I'm sorry to hear you're running into issues. I'd suggest that you check the keybindings in the project settings. You can navigate to Project Settings > Engine > Gameplay Debugger > Input to ensure that the keybindings are correctly set to the desired keys.
For anyone having issues with the WieldSword functionality, it's good to know that I didn't show how to edit it to include an animation, but it is the same as the UnWieldSword, so if you want to add that animation make sure to also include an event dispatcher (Call onWieldSword) from your enemy blueprint, and update the task to only Finish Execution when OnWieldSword is dispatched (Just like we did in the SheathSword from 40:45 to 44:20)
When you say "update the task" - which task or do you mean create a new task for equiping it?
@@djtc2093 here I'm referring to the wieldSword task in the behaviour tree, because a lot of people had issues with this, and almost everyone forgot to call finish task (with success true) ONLY when the onWieldSword event is dispatched
@@AliElZoheiry 100% - thank you.
can you please add the files for this tutorial please? (if you still have the proj files that is)...still heaving problem with it, after i followed your instruction for debugging the WieldSword functionality
BTW, the problem i had, was in the SheathSword and WieldSword tasks...i was connecting the finish execute to the bind event instead to the finish custom event respectively in both tasks
These are seriously the best tutorials I've come across. No fluff, great pacing, and even though they're over 40 minutes long each, I know they're worth watching bcz you do such a good job explaining everything, and it's not filled with useless information like modeling a character first, or animating something, straight to the point and topic of the tutorial. Thanks for all your hard work making these AI tutorials, they couldn't have come at a better time for me since I'm implementing a combat system right now. You've definitely earned a subscriber.

@@AliElZoheiry I'm a game designer with 25+ years of experience working in various proprietary engines and I'm learning UE for the first time. I cannot thank you enough for putting this video together! Teaching this old dog some new tricks! 🤣🏆🎉
Your tutorials are absolutely insane and I really enjoy watching them. You really find the right balance of digging into topics, tempo and - my personal highlight - level of coding quality. Looking forward to see and learn more from you!
Wow! Thank you so much for the support Max. This means so much to me, I appreciate you 🙏😊
This series I by far the best taught content I've watched on Unreal here on RUclips

Really happy I could help you Gameboy, I appreciate the support, and looking forward to teaching you more.
@Ali Elzoheiry I'm currently watching and following part 3, and I'll be very excited to see what you do next!
very well explained, without having much idea of English I understood everything! For the following videos, thank you very much! greetings from BCN
Hey Sergi, thank you for the support, I'm very happy you found this useful ☺️🙏
Hi, Ali. I am learning so much from your tutorials. I do have one suggestion. Make sure that what you are referring to is visible on the screen. There are many instances where what you are typing is cut off. This is true whether it is in the window or full screen. Thank you for the hard work on these tutorials. This is helping me understand AI.
Thank you, I indeed noticed this in a few other videos, In my latest 2 videos I started only zooming on important details which would otherwise be too small on screen, so hopefully this issue isn't happening anymore
Thank you soo muchhhh!! im a C++ developer and making a stealth game, sadly the ai documentation is very bad and usually i take the Bp logic and translate to c++ in a optimal way. You r awsome!
Yeah the documentation for C++ is quite lacking, I will be making some C++ tutorials as well soon because some systems are only available in C++ so stay tuned ;)
مش شايف مصريين كتير يا بشمهندس علي بس بجد أنت فخر لينا أنت من الأخر جاااااامد شكرا ليك جدااا❤❤❤❤
شكرًا جدًا لك! سعيد جدًا إنك استفدت من الفيديوهات 🙏
Learned so much from the firs episode of this series. I didn't know anything about behaviour trees and after watching the first episode and then practising on my own I am a lot more comfortable with it. Thank you Ali you are my Unreal Sensei, keep up the excellent work :)
I'm very happy to hear that, you're welcome man, thank you for watching 🙏
Starting this series after completing load and save system which was fantastic. You teaching style is amazing - problem and solution based which i found very helpful in learning process. Just leaving this comment to encourage you to produce more videos in more series especially in multiplayer system login using facebook/google, messenger style chat using dedicated server , and save and load in multiplayer system. Keep up the good work man . Cheers 🎉
Hey, thank you so much for your kind words and suggestions! I really appreciate the support and I'll definitely keep your ideas in mind for future videos. Cheers! 🎉
This tutorial is everything i pretty much been looking for so far. Wow
Glad it was helpful! Thank you for watching 🙏
I like that the way you design these, you are using best practices for how you would set it up for an actual game. Most tutorials just focus on getting it functioning superficially for the purpose of the video.
Thank you for your comment! I really appreciate it. My goal is always to make sure the tutorials I create are not only functional but also designed with a real-world game development approach in mind. I'm glad you noticed that! 🙏
Thanks for the tutorial series. Very clear and easy to understand.
I got stuck for atleast a day trying to move from the "set movement speed" to the "Move along patrol route" stage.
Watched the video over and over and couldn't figure it out, added loads of print screens and got nowhere...
It turned out that I used a selector instead of a sequence for the patrol state... FML :D
onto Episode 3!
Glad you found the solution at the end, sometimes some patience and trial and error is what it takes
Best Unreal AI content I have seen. Amazing work!

Thanks! I'm really happy to hear that you find the videos helpful. I'll definitely keep them coming 😉
Im a complete noob and managed to follow this great (yet complexed) tutorial.. I kept leaving comments asking for help but then would follow the logic from what I asked and debug.. Then comment again with a new problem and delete as it changed aha. This is my final comment to say thank you.. Most my issues were to do with leaving a box unchecked or not connecting a pin for example I hadnt connected WeildSword to execute Bind event in the BTT_weildSword and in Sheathe sword so the BT wasn't finishing the task and getting stuck haha.. Having the comments to read through definitely helped me to fill in gaps on parts I had missed or you had done outside of the edit. Thanks for another great tutorial. Took me about 4 hrs as a noob to troubleshoot my mistakes :)
Hey, thanks for sharing your journey with the tutorial! It's really great to see how you were able to troubleshoot and solve the issues on your own. Your perseverance definitely paid off. Glad the comments were helpful, and I'm happy you found the tutorial useful. Keep up the great work!
thanks so much. I am quite a noob with unreal AI, and I followed along quite easily and had no problems getting to work.
You're most welcome Supa, always happy that I could help ☺️🙏 thank you for watching

this episode ruined it for me bro, everything was going amazing until this episode, about 3/4ths through the video things began not working right with the enemy, after the whole sheath thing. i followed exactly and went over things three times to ensure no node is incorrectly done, i can see a LOT of others had issues here too, i went on after this video and the other videos are good but this one is the issue one, i know you've defended your edits and actions in the comments but this video seriously desrves a re-do, but go over things completely as you do them, this is the ONE video hurting this entire playlist..
i found this video on reddit, on the UE sub there was about a dozen users who praised the tutorial but warned against part 2 of it, which i ignored because i assumed that i could figure out where they had issues, looks like it got me too, this video is mostly good but had a vital error keeping it from being as polished as your other vids, please re do it bro.
DUDE yes!!!!! I found this on reddit yesterday too but not on that sub, it was from the game devs sub, u/NoFrillaz or whatever shared it but told people to skip the second video because he skipped a lot of steps later on in the vid and it messes up a lot of ppl lol I've been trying to redo things 4 times now and have the exact same issue!!!! it makes me so angry because everything else is SO good!! but darn it
me too I am having trouble with it around that part , my enemy freezes and jitters when supposed to be switching, I agree I wish he can remake it, please Ali
yes bro it was all good until this one, its hard to explain to him about what mine does but reading all the other comments i can see everyone that has issues with this vid, hasthe exact same issue because mine is doing same and it just make me frustrated and i've rechecked everything, please ali it won't take much effort to just redo this one, it will make ur playlist perfectly i've done the following 3 videos after this one and they all are good but the issue on this video has roots that lead and branch out to the after vids.... i've redone this tutorial 3 times now because of this issue, thinking i missed something but no, it's literally all from the sudden addition of nodes later on, even if u mentioned a few changes at the start that doesnt gloss over things, just please redo it in full and show things as you mention them!!! @@BadNewsStudio
i'm having issues too, with the wield sword function part, i know he pinned a comment with a solution but that doesn't quite resolve things in full. i'm hoping for a re-do too haha, i've been stuck on this video for 4 days now
Hey all, just to be clear, there is nothing wrong with the tutorial, you can follow it from start to finish without any problems. The reason I wrote this comment, and the reason you might be having issues, is that event dispatchers, and behaviour trees are a new way of working for most of you, so it can be confusing, but I assure you, the content itself is tried and tested and works perfectly, if you are having issues, feel free to join the Discord server and we have a youtube-help channel there where you can ask your question, provide details, then I or someone else can help you there. Just make sure first to check the existing questions in case you find the solution you're looking for.
Good luck 🤞
Thank you teacher Ali. Like part 1 your tutorial are very detail moreover your teaching and how you explain are really amazing.
I also consider WieldSword function that didn't show in video as homework.
Even now I cant count the spline point and don't know why it need to -1. The Spline point function are the last thing that I cant understand.
Also it took me nearly 2 month to understand overall how the function operate, That make me realized how I lack of the foundation [Gonna cry in corner]
for example you have 10 spline point in your patrol
spline point index 0 = spline point 1
...
...
...
spline point index 9 = spline point 10
index as defaulf start 0 but your point of number going 1 , 2 , 3...
Thank you so much
Hey there! Thank you so much for your kind words and for sharing your thoughts. I appreciate your dedication to understanding the concepts. Don't worry, taking your time to fully grasp the material is commendable, and it's okay to take a bit longer to fully understand everything. Keep going, you're doing great! 🙏
P.S, checkout the response from @DaviesMurphy, it sheds light on how incrementing the spline point works! Thanks for that Davies

Hi Ali , im really excited about the series . Im just bum out that sometimes i dont understand your math, especially the Patrol Index. Im trying my best to understand it, had to crush my head. Hopefully ill knock some sense into my own brain :D
Hey Danny, let me try to explain it simply. The patrol index is just the point on the spline that the enemy is currently on starting at 0 (meaning the first point) so when the enemy moves to the next point we need to add 1 to that index (so then the patrol index is equal to 1 which means the enemy is at the second point in the spline) then we need to check if we reached the end of the spline, by checking if the index is equal to the number of points in the spline (but minus 1 because we started at 0 not at 1) then if we reach the end we just start subtracting 1 from the patrol index instead of adding 1 (this we change the direction to be -1) and do the reverse once we reach point 0 on the spline again. Hope it makes more sense now
@@AliElZoheiry Hey Ali ! Thank you very much clearer now , thank you so much !

I have a problem with patrol system , chasing and attacking is perfect but patrol is not working properly sometimes enemy stops suddenly and the patrol happen only once he does not repeat it by getting back to same starting point . I assume that the problem is with my landscape, as I am using a desert landscape it has many up's and down's i think this might causing problem but again sometimes character travels the end point even spline is under landscape but again not returns he just wait there.
Hey! That sounds like a tricky issue. It could definitely be related to the landscape’s elevation. Make sure to check both your spline's setup and the logic for returning to the starting point in your patrol behavior. If the spline is under the landscape, it may not trigger properly. I recommend adding some debug prints to see where the issue comes from. Hope that helps! 🙏
I was stuck for many hours (using 5.4) that the enemy did not unsheath the sword and just stood still. The fix was to change the play rate in the first Play montage to -1. Because the animation is set to -1.
Glad to hear you found the fix! It's always the small details that can make a big difference. Thanks for sharing that solution! 🙏
I'm sorry, I am having trouble assigning the patrol route spline to my character. I can't find any linkable parameters in my BP_Enemy_Base to the spline and your Video is blocking the view at 8:50 Any clues?
Great tutorial btw!!! Congrats!!!
Hey Erik, so the "PatrolRoute" variable we created in the enemy class should "Instance editable", which means you need to click on the "eye" icon next to the variable name in your blueprint, or make sure the checkbox for "Instance editable" is checked. Then when you select on your enemy in the World. You can search for that variable in the details panel and assign it the value of your patrol route (which also has to be placed in the world first)
THX!!!@@AliElZoheiry
Thank U!!!! U are the best. @@AliElZoheiry
So a few things...I'm going to hang with this but you move a little too fast and I think you forgot to show what you did around 41:00 regarding the changes you made to the initial Weird Sword. But so far I'm liking it.
Hey, thanks for your feedback! I indeed didn't show the changes to the WieldSword, because they are exactly the same as the SheathSword event, and I showed the event in the blueprint, so you can pause and see what's happening there if you'd like

You're very welcome! Thank you for watching
I'm asking you a question through a translator because I'm Korean, but I don't know if you can translate it accurately.
I have two questions.
1. When the game goes on, the character immediately pulls out the sword, puts it back in, and moves to the spline point. When the game goes on, I want the game to move right away instead of pulling the sword out and putting it back in. How do I fix this?
(Solve: Weild Sword was applied to Beginplay.)
2. I've never solved a non-soft animation with a character movement either, is there a way to go to the line instead of spline point?
(solve: It was solved when I changed 'use controller rotation yaw' to false. However, if you change the function to false, the character will look in the opposite direction when you press the '2' key.
So, in bp_enemybase, 'Set Controller Rotation Yaw' is set to true at the front of FieldSword and false at the front of SheathSword. Also, in bp_enemybase (Self), the default value of 'Set Controller Rotation Yaw' is set to false.
Through this method, the original value works as false, true when the knife is taken out, and false again when the knife is moved.
I don't know if this is the right method, so if you have a problem like me, please try this method and verify it.)
+
If the next motion does not occur after drawing the sword, check 'Call On Field Sword' is connected to On Completed in 'Wield Sword'.
It took me an hour to find the problem..😂
I've found a solution, but I won't erase it to present a solution to someone with a problem like me.
Thank you for your detailed explanation and providing solutions to your own questions! It's great that you've found a method that works for you. Your willingness to share your process to help others is really admirable. Keep up the problem-solving spirit!
you are really best, im deleted my old ai system in only BP and im trying to use now BT. You are best man and you are best man again and you are best best man. Change your channel name to "BEST MAN"

I just have a question, I want to have a box that spawns the monster when the player collides with it, but when I do that and spawn the monster, it doesn’t have a patrol route selected and I don’t know how to make it come with a patrol route already set. Btw I am spawning a new ai and setting it to the enemy when the box collision happens, it does everything except follow the patrol route if that helps.
Hey there! In order to have the monster spawn with a pre-set patrol route, after spawning it, you will have a reference to the spawned character. Then you can just get the PatrolRoute variable from that reference and set it's value to be the reference of the patrolRoute from your level (you will have to get a reference to that patrol route first though, and how to get that reference will depend on how you built your game)
@@AliElZoheiry thank you so much
OMG, I rewatched the video three times now because some things weren't working correctly and every time I forgot to set the succeed boolean to true in the finish execute note...
Hey there! It happens to the best of us 😉 Glad you figured it out in the end!
I'm finally up to speed on this video, got everything working, the only issue I am having is with the enemy attack when I am really close. The way it starts is on attack, They focus and run at me to attack, but then when I get really close, the enemy stops turning, and instead, will start attacking in the direction they were looking at until I separate myself with enough distance for them to turn towards me. I tried messing with the "Move To Target acceptable radius "which did help a little, but even at "0" they still wont turn when I am really close. Does this get covered later on, or maybe there is someway to make sure the enemy will always rotate towards me before attacking?
This isn't a huge deal, I can always fix this later on for my project. Anyways, thanks for the vid! Cheers! 🙌
Hey there! Thanks for your feedback, I'm glad you're finding the video helpful. It seems like the issue you're facing might be related to the way the enemy rotation is being handled. I'd suggest checking that in the base enemy pawns character movement you have "Use controller desired rotation" set to true. Hope that helps and best of luck with your project! Cheers! 🙌
@@AliElZoheiry Thanks for the response, yeah I have "use controller desired rotation" set to true, the enemy just didn't want to turn when I was really close to them for some reason so I did mess around with some settings to see if I could fix it. But yeah, everything seems to be working now because in part 4 video the enemy is given a "strafe" in the BT so now they strafe around me while in attack which is perfect.
I know you get a lot of comments on this series but I really do appreciate all the help! 🙏
My pleasure @@TrackstarOPhappy to help where I can 🙏
Great content so far! My AI has been severely lacking. And, these videos are just what I need. I'm wrapping up for the day. I've only had one issue that I cannot seem to figure out.
When I press "1" the first time, everything works great, and I created an UnsheathSword Montage similar as you did, and spawn the sword using a Montage Notify as usual when working with Notifies. But, the Enemy will not turn to face the Player as it unsheathes the sword. It will unsheath, then turn to the Player everytime. I've tried playing around with different things, and I'm not quite sure what is going on.
Other than that everything looks great. I've debugged the AI Behavior Tree, and it looks like it flashes by the BTT_FocusTarget(with AttackTarget as the Attack Target Key) and goes directly to the BTT_UnsheathSword I created under the BTD_IsWieldingSword Decorator. That is all within the first sequence. The numbers on the nodes look correct. I'm not sure why it is skipping the BTT_Focus Target Task though.
EDIT: For now, I'd just added a Wait 0.5 Seconds Node to the middle of the sequence. So it will Focus wait half a second, then unsheath the sword. This gives the AI enough time to turn and face the player, even if directly behind the AI. Using 5.2.1, but don't think much has changed in this regard.
Thank you! Glad you've been enjoying the content
If your AI is taking a long time to turn it could be the rotation speed of the enemy character is slow. If you're not using the default manny character and default settings, make sure to match it to the default manny settings for rotation speed and see if it helps
@AliElZoheiry - Thanks for the tip! I was actually thinking the same thing when I woke up this morning. Oftentimes, I wind up waking up with a proper solution XD
Just got in from some morning endurance cycling. I'm going to get going on my projects in a half hour. And, this will be the first thing I test. Adjusting the turning/rotation speed on the ai mesh.
hey man, did you figure it out? i'm having the exact same issue as you and i don't think it's the rotation speed
@@Dominicn123 - Sorry. I never did figure out the issue with the enemy not facing the player. I just left in the Wait half a second node to the AI Tree which I mentioned above.
At this point I think I'm running off a copy of one of Alizoh's source files I downloaded a while back. I didn't think of looking for the change in the source for that particular issue. When I downloaded the source project, and started working off of that.
thank you for your efforts brother. my main language is not english. Selam in Turkey. I solved my problem. Press " 1 " not moving npc. Solution in " BT_Enemy_Base " > BTT_SetMovementSpeed > Movement Speed (in right) > Spritting. Not Idle :) I hope it was helpful :)
Hey Ahmet, glad you fixed the issue, well done 💪
In part 1 we built the "BP_Enemy_Base" code (pt 1: 37:00 - 41:07). But it looks like that code got replaced by completely new code, of unknown origin, appearing here in this Part 2 at 8:16.
I've spent a week on this tutorial. I've redone this and part 1 a few times now, and I can't get it working. Here's how mine works:
Press "1" the first time: Enemy just stops patrolling and stares at me.
Press "1" twice: Enemy slides along his patrol zone and continually unsheaths
Press "1" third time: Enemy slides, then finally runs and attacks me.
Press "1" fourth time: Enemy sheaths a few times and returns to his Patrol Path; the sword never disappears.
After tearing out most of my hair, I gave up and downloaded the project zip. When I open that project and play, the Enemy AI faces me, unsheathes, and then runs behind a wall, faces the wrong way, and swings at empty space a few times.
Is there a way to get a project download at the point where the action makes sense at the end-point of this video?
Hey Heavenseek, so the enemy blueprint was not completely replaced with something else, as mentioned at 1:14, I just changed the WieldSword event and behavior tree task to include an animation and an event dispatcher, which I proceed to explain at 38:20. It sounds like your problem is likely with the wield sword event and behavior tree task, make sure that in the WieldSword event you dispatch OnWieldSword and in your task you bind to this event dispatcher and only call Finish Execute then, just like we did for the unwield task at 43:55
@@AliElZoheiry Thanks, I'll search for those and try to fix.....
@@heavenseek Hey man, I found a bug in the engine that might be causing your issue. It happened to me today when I restarted the engine, I found that the Blackboard keys on the "BTT_MoveToIdealRange" in the tree got reset and I had to manually select them again. Meaning that I had to Change the "IdealRadius to be either the AttackRadius or the DefendRadius (depending on whether I'm attacking or strafing) and the AttackTarget set it to AttackTarget as well. Hope this helps
@@AliElZoheiry Thanks very much, I will definitely check that out! 🙏
This is exactly what is happening to me. I followed the directions exactly and have gone back through them several times. I can't see where the discrepancy is. I'll take a look at Ali's suggestions here.
This is probably a specific problem I had but an easy fix anyway, my set focus wasn't working so the AI didn't focus on the player before drawing the sword, then I found out that I set the AI rotation settings to Orient Rotation to Movement instead of Used Controller desired Rotation.
Glad to hear you found the solution! It's often the specific details that can make all the difference in debugging. Keep up the good work!
Im pretty new to this whole UE world but at 32:32 where you cast to the AIController couldn’t you just add the AIC as a Component in the Components Menu to gain access to all its variables and stuff?
Hey! Indeed that is of course possible, but this is just part 2 of the series, things get a lot more complex as it goes on. This is only done to ease people into the topic
Hey Ali, I'm having a problem with patrolroute, can't increment in the task. Tried everything it just doesn't give me the node increment!
Hey! if you don't see the increment function, then you are probably trying to call it on the wrong actor reference, make sure you have the right reference to the BP_PatrolRoute to call the function on it
@@AliElZoheiry Thanks man, solved it!

This tutorial is great thank you
You're very welcome! Thank you for watching 🙏🙂
I am trying to apply Walk Patroling to my Enemy, but instead of only Walking, some points Enemy is Walking and some points Enemy is Running, Its doing both. Any suggestion.
Hey! If you're points are not evenly spaced out, then the enemy might be accelerating faster and slower depending on your acceleration speed and ground friction and deceleration settings in the character movement component. These all affect how fast your enemy moves
Hey, thanks for the tutorial, everything is working fine now. However, i faced 2 problems and i want to share them in case anyone is facing the same issue.
Problem-1. The BTT_WieldSword function in the behavior tree was running endlessly and sword was not being equipped. I rewatched the video again to find the solution.
Solution : The notify name on the animation montage should be same as the switch on name function in BP_Enemy_Base.
Problem-2: The SheathSword function was not working properly.
Solution : I forgot to do one step. I had to go into BTT_SheathSword function and from the as BP enemy base drag out a node and search for bind event on sheath sword, this will automatically create a custom event for you as shown in the video. And connect your custom event to finish execute. You have to do this for both sheat sword and wields word functionality.
These videos have been such a help! Thank you and keep it up! +SUB!
Thank you for the support 🙏 I'm always happy to hear that my tutorials are helping people, I hope to continue helping you :)

I'm using ue5.4 and i have an issue where when i hit the 1 key it will not switch over to attack state. After an hour i tested my keys using a string to call hello and that was not working either. Can someone tell me whats going on with my keys?
Hey, no idea honestly, if you're print string on key press didn't work, then it sounds like you got a problem with your engine itself, because there's nothing specific to get input keys to work. just double check your setting the right key and try different ones. also restart the engine or install a different version
My Enemy is Patroling only 1st point of the spline after reach that point Enemy starts idleing and not patroling anymore. I cant understand what am I missing.
Hey, thank you for sharing your issue! It sounds like you are not incrementing the patrol Index correctly. so double check that part of the video
The more better way instead of using a Interface or Cast is to Store Data in ActorCOmponent , this is a great feature using which we not only make Less Coupled things but also modular things
Hey Brock, thank you for the feedback. I indeed use actor components heavily later in the series when I start integrating a damage system and attack system
@@AliElZoheiry I see, that's great then and btw I loved your end result that's why I started watching, if you could make a enemy which can predict player moves like attack, flank
I followed the steps, but right at the beginning, when the simple test is performed to follow the path, mine stops right at the starting point and doesn't move forward.
Sounds like you're not incrementing the pathIndex correctly
Thanks a thousand times!
You're very welcome! I'm thrilled to hear that you found the content helpful. Thanks for the feedback! 🙏
45:58 When I press 1, the enemy just runs towards me and uses the Sword_slash montage, but the montage_Sheath_Sword and montage_Unsheath_sword animations don't work, even the BP_sword sword doesn't appear, I checked and followed everyone's comments but still not successful, is there any way, please help me
1. Make sure that you are connecting the skeletal mesh to the montage
2. Make sure there is no typo in the montage notify name
3. Make sure you are using a Montage notify and not a regular notify in your montage asset
4. Make sure you pulling the switch off of "Notify Begin" pin in your play montage node
9:36 Use interface instead of casting
(because the 'increment patrol route' function will apply to all types)
Thank you very much😲
Thank you for the suggestion! I appreciate your input on using interfaces for a more versatile solution.
8:38 (in Scene)
Hello Great Tutorial,
I had a problem where i couldnt change the movement speed for the enemy player. It really took me a long time to find my problem:
at 19:35 he added the "max walk speed",
i mistakenly added "max movement speed".
cheers
Hey, thanks for your comment! I'm glad you enjoyed the tutorial and identified the issue with the movement speed. It's great to hear that you were able to troubleshoot and solve the problem. Happy coding! 🙌
Hi Ali! Your tutorials are awesome and really help me, but I have a problem when the enemy puts away his sword, he starts doing it endlessly. I did everything right. I redid it a few times, but nothing changed.
Hey! Thank you for your kind words 🙏 Regarding the issue with the enemy endlessly putting away the sword, it sounds like you are ending the task before the Sword is actually put away, so double check the montage notify spelling, and that the switch statement coming out of the play montage node is coming from "OnNotifyBegin" and also check that you're correctly binding to the sheath sword event in the behaviour tree task correctly
@@AliElZoheirythank you very much for your answer , the problem was in the Switch on Name, the name was different from the name in anim montage)
Followed this almost 100% and tried to use the instruction on sheath sword to also create and unsheath and it just gets stuck in the behaviour tree in the first branch of the wield sword line...
Common mistakes are:
- Typo in the montage notify name (either in the montage or the switch statement off of the play montage node)
- You used the wrong type of notify (regular notify instead of montage notify will not work)
- You are not pulling off of the NotifyBegin in your play montage node (before the switch statement)
- You are not binding correctly to the event dispatcher
These videos are really good :)
Thank you so much for your kind words! I'm really glad to hear that you're enjoying the videos. If you have any specific topics or requests, feel free to let me know. Happy learning!
Seems like I can't have multiple enemies near eachother when I have any of them patrolling. I assume that's covered in a later tutorial but I just finished #4 and didn't see a solution yet. Any suggestions?
Not sure what you mean by having multiple enemies near each other. If you mean that you want multiple enemies to use the same patrol route, then you will need to store the current point on the patrol route in the enemy instead of in the patrol route blueprint (so that it's unique per enemy instance)
@@AliElZoheiry I’ll try that, thanks! And for whatever reason when I had a patrolling character and an idle or wandering character within sight range they would both freeze. (With two wandering enemies it mostly works)
Hi Ali, amazing video as usual, always top tier videos, thanks for your knowledge!!
Quick question: i implemented a patrol route for one of my maps, and i spawn allies who will travel through it regularly (moba style). They should go from index 0 to last index, BUT all get assigned the same single patrol route and the patrol index number keeps changing each time i spawn one, so they do not follow 0 -> 1 -> 2 - > ... last index.
Is there any way to have them kind of have their own instance of the same patrol route?
Thanks in advance and please keep up all the amazing work you do !
Hey there! Thank you for your kind words and for reaching out. This tutorial assumes one patrol route per enemy, not multiple enemies following the same route. The main difference is that the PatrolIndex (which we increment when the enemy moves to the next point) is stored on the BP_PatrolRoute itself, therfore multiple enemies can't share it, because when one moves, the index increments and the other enemy will also read that same variable and move to the same point as the first enemy.
To have the patrol route support multiple enemies, you need each enemy to store their own PatrolIndex route, and increment their own copy of that variable
These videos are great! I find myself stumbling through UE5, how did you get to the point where you could build behavior trees, tasks and functions on the fly?
Thank you! I'm glad you're finding the videos helpful. Building behavior trees, tasks, and functions became easier with practice and experimentation. I recommend trying out small projects to gradually build your skills and confidence in UE5. Keep experimenting and learning - you'll get there!
i have a problem where the enemy not chase me after i pressed 1, then, when i disconnect the patrolling sequence, the enemy not moving at all
Hey there, sorry to hear you're having issues. I suggest debugging the behavior tree to see what node is executing when you press "1" (by looking at the tree while the game is running)
@@AliElZoheiry i have found the issue and have fix it. Thank you sir. Love your tutorial and hope I can learn more from you
the switching states is not working what could be the problem
Hey, it could be anything really, you need to do a bit more debugging to narrow down the problem area
If you still need help you might just need to check inverse condition on BTD_HasPatrolRoute in the Behavior tree but, that's only if your issue was the passive not working
im getting a strange issue where when my mannequinn model tries to attack, the frame before he swings he looks another direction away from the player then plays the attack animation facing the player, its only a split second but noticable. not sure if this is due to an animation issue or if the behaviour tree is setting the AI to some other state and its causing that. Any suggestions would be appreciated! thank you :)
i have a feeling its to do with the animation and nothing to do with this tutorial.. perhaps something to do with root motion settings... :( its very strange, the mannequin seems to rotate the same direction just before the attack animation and is always the same direction so depending where im standing in relation to him it can look quite bad he does a 180 sometimes for a split second before attacking
He's probably losing the focused target for some reason during the attack, I suggest adding a breakpoint in the flow and seeing at which node it starts failing
is there any way like without having pressed 1 the enemy goes patrolling and then when in range attacks the player cause in the video 1 is being pressed to change states of enemy is there any other way round ?
Indeed, that is what i do in the rest of the series. Keep watching ;)
@@AliElZoheiry Sure and great series will love to watch more from your channel
In the behavior tree tasks that you create you are casting to the enemy base class. Do you think it would be more efficient to either update the BBkey through the enemy blueprint by using "get ai controller>get blackboard>set blackboard value as..." OR would it be better in the behavior tree to cast only once and store the enemy reference instead of casting every created task?
Once we start adding the enemy AI interface, I won't be casting as often since I'll be calling interface functions, but in general, casting isn't a performance heavy operation, so you can cast on each tick, hundreds of times and it won't be a performance issue unless it's thousands of times per tick
Anyone else having issues with "get spline point as world position" at 12:49? I can't get that.
Edit. NVM After UE5 Crashing it had not saved the function in BP_PatrolRoute
Hey! Glad to hear you figured it out. Crashes can be frustrating. If you encounter any other issues, feel free to ask! 🙏
Thanks for these awesome tutorials! I do have one issue with the Blackboard Decorator that is on the CombatState Selector. With it on, the enemy only runs the PassiveState side of the BT. With it off, the enemy will try to move to AttackTarget, but slingshots around the area never actually reaching the player. I don't know what the issue is, but any insight would be much appreciated.
I'm not really sure I understand the issue, but if it is regarding the decorator not succeeding/failing correctly, then I suggest checking the implementation of the decorator and seeing when it returns false/true.
Otherwise, some common mistakes are:
- Using "Selector" when you mean to use a "Sequence" node
- Setting the wrong input parameter to a decorator or task
my character seems to be floating and not performing any animation as it moves. How do i fix that?
No idea, it could be anything really. You'll need to debug further to narrow down the problem area
Excelent Video, I have a doubt, in my case my character when he appears on the map makes the animation of drawing his swords, but I want him to not move while he is doing it, so I put a wait at the beginning of the Passive State, it worked but then to advance point o'clock it is also expected, do you know how to make the wait only at the beginning and not repeat itself anymore, thank you.
If your character is doing an action and that action is triggered by a behavior tree task, then you shouldn't Finish the task execution until the action has ended, that's why I added the event dispatcher in the wield and sheath sword functions, to tell the task that the animation is over and you can move to the next node.
This is what you should do as well, because a wait node won't work for all animations since they have different timings
im very new to UE5. Increment control route doesn't exist for me when trying to pull off from patrol route. Not sure why :(
Hey! It sounds like you might be looking in the wrong spot. Make sure you are trying to call the function on the correct actor. If it doesn't exist it means you are pulling off of a wrong actor type
@@AliElZoheiry ok I'll check it out, thanks. Also by chance could I get your discord? It'd be easier to send an image of what's happening...
Thank you, your tutorials are amazing! But unfortunately I can't solve the problem in one place - In the behavior tree the logic always gets stuck after BTT_Wield_Sword or (when pressing "1" again) BTT_SheathSword. Could you please tell me where I could have made a mistake?
You know what, I was having exactly the same issue and I found the solution : You need to follow exactly the same process that you did for "BTTSheathSword" task, meaning bind the Event to On Wield Sword at the end before Finishing execute :) (referenced step for the Sheaf in min 49:24 of the tutorial)
@@camillemjx9674 Thank you for your reply! But if you're talking about the 44:20 moment, I've already done it in both BTT and got just that, the character picks up the weapon and just stares at me. ( Or when I press 1 again, he hides it and stands there).
Hey Depreska, if the task itself get's stuck (meaning that it get's activated and never ends) this means that you aren't calling "Finish execute" with success = true in your behavior tree task.
Either that, or you're montage notifies aren't being called when playing your wield/sheath montage animations. Make sure that you connected the Switch node in the montage from "OnNotifyBegin" and not off of any other pin, and also make sure that your notifies are named correctly in your montage and don't have any typos
@@AliElZoheiry Thank you!
Unfortunately, I was just inattentive, and did not connect the Call On Wield/Sheath pins in BP_Enemy correctly, instead of “On Completed” I connected it to the topmost one. >_< Time to start learning during the day instead of at night.
('''')(^_^)('''') Thanks again!
Amazing tutorial. I do have a small problem. When the enemy reaches one of the spline points it waits for halve a second and then continues to move again, but it doesnt smoothly continue as shown in your video. Any idea why this is happening?
It could be the character movement settings you have are different, things like acceleration and friction can affect the movement of your character. I am personally using all the default settings that come with the UE mannequin (except the things I changed in the tutorial)
Noob question. How do you enable the search bar in the context menu? I don't have it by default.
CTRL+P
Ctrl + P Indeed ;)
Hello. In the video at 32:40, you add "Cast to AIC_Enemy_Base". When I press 1, it stops right at this Node. The cast simply fails. What could be causing this? Thank you
The only reasons for the cast to fail is either you are casting to the wrong class, or you didn't set the AI controller to the pawn
@AliElZoheiry buddy my AI whenever reaches the point of the spline it slows down and almost stops for a 0.1- 0.2 sec, is it possible to nake the movement smooth so that it won't stop on these points and rather run smoothly through the spine
The AI stops because the MoveTo task finishes and there is a slight delay till the next one (but it definitely shouldn't be 0.1 -0.2 seconds, more like 0.05) if you are experiencing a longer stop that what I have in my example, try playing around the the deceleration values on the characterMovement component (things like deceleration speed, ground friction, acceleration speed, etc..)
If you want it to be completely smooth, then you'll have to start the next MoveTo task before the enemy reaches the next point on the spline, meaning that you have to check when the enemy is "almost" at the point, and then start to move to the next one
@AliElZoheiry thanks i got it how to fix it. Btw Amazing work👍🏻👍🏻🔥🔥
