Excellent tutorial, excellent blueprint organisation & structure. It is one hour long but it is extremely satisfying to see such clean content, you're pace is great, I also didn't need to pause during the whole process. And it works like a charm.
I've seen a lot of your tutorials and I see that you have an excellent level on UE4. I'm trying to build a "fairy in Zelda" type pet that follows you while flying and can disappear automatically, and can also be used as a target point when you lock an enemy. Do you think this is something you could do in a tutorial because I have no idea how to approach the problem?
Little updates for people trying it in UE5 (it works by the way): "float x float" and "float > float" and similar comparisons were stripped from the actual datatype, instead there are general methods, that do type checking well abstracted away from you on the inside.
25:20, Troubleshooting note: I wasn't getting it to print anything on my first try, even though the nodes and settings were all correct. The problem was I modeled my turret already assembled/floating, and that means my turret top pivot was on/in the floor so it couldn't see anything. Because the world location of the Has Line of Sight node goes off of the input's pivot, the tutorial didn't have this problem since the turret's top was moved up in the BP. Solution: Add an arrow utility component to the BP, move it up to around your top turret piece, and then make the arrow the parent to the turret pieces. Then set the arrow as the input for the Has Line of Sight node.
So i have studied this video for about 1 mounth now. I have come to the conclusion that at the actual state of thing, is much more efficent to do this using behaviour three and Blackboard. The reason is that if for example the target hides behind a wall and you would like for example to wait about 5 sec before make the turret go back to the original position....the things kinda became complicate. So after trying and trying i have succeded using set timer events and adjusting some variables here and there, but still i was having some problems for example if i was out of the turret range, the turret was still on going....and every time i had to modify the algoritm, was kind complicate. So i tried doing the dame thing with IA and IA sensing, and a combination of tasks and service for the searching and shoting of the target. I used most of your algoritms and the result fit much better in my needs and it's easyer to add new behaviour this way. But thanks anyway for this great tutorial.
Unfortunately this doesn't act the same as the turrets you show in the beginning. Once it acquires a best target it then keeps firing at said target once even after it goes out of range. It only stops when a new target comes within the sphere and then it will just constantly fire on that one. This can be fixed by adding two nodes. Between the SphereOverlapActors node and the ForEachLoop add a branch. The branch condition will run off the boolean return value on the SphereOverlapActors. then pass the exec from the SphereOverlapActors to the branch, then the true output to the ForEachLoop. Then on the false part of the new branch have it set an empty Target variable. This way when no actor is within the sphere it wipes whatever is stored as the Target
thank you, I followed your lesson carefully and everything went well. I use this as the basis for my idea for Tower Defense RTS. I modified some things for other types of towers so that it can rotate differently, like the top rotates in pitch and the base in Yaw.Thank you again grate tuttorial.
Love the video. I am applying this to a turret that I have modeled myself and the head of the model will turn 90 degrees before tracking and will tilt. I have turned off gravity for the top of the turret as I thought it would be the head is to heavy or something but I was wrong. Can I be pointed in the right direction to stop the 90 degrees when it starts to track the player and if there is anything I have missed for the tilting of the head. Thanks
probs 2 years to late too type here but when i did the rotation part of the tower i have the tower head looking at me from the wrong angle i have the side facing me rather than the front
When I do this, "Has Line of Sight" line trace is always true, even when I'm behind other objects. How come? Do objects need to have some property to make the linecast not work? I checked the "From" and "To" vectors within the function and its correct.
You are doing really good job, I'm really thankful 🙂 I'm really trying to learn GTA V style Game for a long time. Now I hope I can find more interesting tutorial in your channel. For ue4 everyone make tutorial I couldn't find all together like ( weapon systems, cover system, vehicle and flying system, AI system ect...) Now I'm going to run thought your channel 😍 thank you so much When I have any doubts or any tutorial needed, can I ask ?
great video ! One Q : why you are setting the relative location of the barells (by timeline) , instead of adding relative location ? it is becase you've attached barrels to a sockets ?
I'm an beginner in Unreal and i have ? hope u can answer them 1. did u make your own custom turret unreal engine or in other program. 2. did u also have to make it shot if unreal engine or in that other program that is if u have to use the different program.. 3. lol sorry for the ? but im a beginner and i have so many cant help but ask
Hello, I am writing from Russia, using Google translator, I have such a question, I don’t see any errors in the blueprints, but the shells from the cannon fall vertically down, and do not fly at the character, how to solve this problem?
Dunno if this will be seen but, For some reason my Line of sight result is reversed... I think. It prints the string when I remove the not bool from the functionlib but doesnt print with the not bool connected. Any help is appreciated! Loving the video.
@@col_panic9802 I had to put 180° in the towers rotation inside the blueprint to fix the watching direction. But this seems unrelated to this thing. Just dropping it here.
also how in multiplayer it will look at ex. other player, and on their screen look at me.. I think we'll need to OnRep something like the target maby idk
Why call the find the best target function every tick? Calling a loop every tick is like one of the worst things you can do performance vice. Why not just call it on begin overlap or something?
you could make it only tick when a character is within a certain range of it, but once they're within a certain range it has to happen in tick so it updates every frame.
Just let them spawn. I used an alien mesh from the store, build a little blueprint to make it spawn automatically and it gets detected, I put the main player / camera into my ignore list, otherwise I get shot in the face when moving to close :D
Late as hell, but useful tutorial! Thanks! Side note, something I've been having a bit of trouble with I want to set the rotation of the "top" part with relative rotation, instead of world. I've seen people suggest using "inverse transform rotation" or "delta rotator", but neither one works for me with the find lookat rotation. Any suggestions?
the origin of your turret head is set up incorrectly. what is probably happening is that yur turret's default forward vector is the Y axis and not the X axis
I had a similar situation. in the function 'update fire' I had a typo for the section that checks the last time it was fired. basically instead of subtracting it, I had function call which said 'min'. I assuming I typed minus in the popup list and selected a 'Min' function instead of a '-' subtraction function.
Overall a good Tutorial but its very slow , and id add a short section at the beginning explaining how it works and showing of the Blueprints before making the step by step part.... so 7/10 , good job , really helped me
I've used this method to make my character auto shoot at targets but I can't use multiple fire modes at once. I made scene component for the mesh which bullets will spawn at its location at it worked perfectly. I added more scene components and duplicated the functions and used Sequuence node for each type of shooting I want but it won't trigger the Fire nodes I have. I changed the mesh inside each function to the scene component I wanted.drive.google.com/drive/folders/12tRItmuLNSYLggI6a9KVwBa02hc63cH9?usp=sharing
