A trace can get expensive on every frame (if you have other things on tick as well) so avoid code on tick. Better to give the NPC a collision box or sphere that will set a variable attached to the player or a component that's attached to the player. To clarify, a trace itself isn't expensive, rather once you get further along in development, if you have a lot of code tied to the frame rate tracing will just add to your cost.
Anyone having issues on 4.24. When you remove from parent in the HUD graph place an IsValid node before it and make the Input Object the message widget. Hope this helps.
So happy about the line trace. I had a lot of issues with the "Interaction Field" from a previous tutorial, and this one is a lot more specific, especially when there are more things in an area to interact with.
For anyone trying this tutorial and not having the display message show up, I was having the same isue (using 4.24). At first I thought it didn't work because my set-up is a lot different than the tutorial's general set-up, ie for movement and such. But rewatching it gave me the answer to why it wasn't working. In this tutorial we do a cast after the event begin play which should make following casts unnessecary, which for some reason did not work as intended for me. While UE didn't give me error messages about needing a cast it did tell me that it was accessing none when truing to do the display message function. The problem was that I did need to put another cast in between the set and display message to my game mode. After I did that, it worked. I also did not need the event begin play to do a cast using this.
Yeah at some point UE4 changed things around how HUDs work, and I've had a lot of glitches along the way. No errors. Just glitches like the ones you're talking about. There was also one where the Display Message didn't go away on leaving interlapping. I don't know what they messed up, I just wish I knew how to fix the wide array of little things it left behind. Thanks for this, that's one little victory :)
Where exactly did you manage to fix it? "The problem was that I did need to put another cast in between the set and the display message to my game mode." Where? All he did in the game mode was these 3 nodes at the 6:01 mark, which don't include a cast.
Great tutorial: quick question. I am doing your tutorial for multiplayer, What replication mode do I select so that each player can get their own interaction (not visible to other players)?
For anyone following this tutorial and who encounters the same "issue" as others with (Accessed None trying to read property PlayersHUD". Blueprint: ThirdPersonCharacter Function: Interact Check Graph: InteractCheck Node: Display Message) or simply the "Press E to Interact" message not being displayed after the instructions for what goes after the print string test, I suggest you to in your project settings under maps and game mode and double-check the project is assigned to the thirdpersongamemode or whichever game mode you're using that is supposed to showcase the "Press "E" to Interact". I was having the same problem and it seems with some version of Unreal (4.24 in my case) the game mode isn't automatically assigned to the project by default and that's what was causing the issue. Hope this helps!
For me it worked perfectly, it’s ver detailed and if you miss any single variable or forget to expose it, it won’t work, so just attention to details and it will work. I just was wondering @Ryan LaLey if it’s not too expensive to try to call function on movement? Especially if the game has many other interactions. What is the benefit of using sphere trace instead of trigger box around each actor ?
Hi i love your tutorials as they are always in a lot of detail but i have a question and was wondering if someone could help me thanks. At the end of the tutorial when i try to search up "Display Message" nothing comes up and i have turned off sentative search to find it. So idk if i have missed something out i was supposed to name something i am using ue4 4.25.1 thanks again.
I have issue with 10:34 . That red thing is facing behind me not in front of me how it should. Anyone has solution? + I do not see the "E" to interact box.
Hello, I'm using your tutorial to develop my VR prototype but I think some node must be different as it doesn't work for me yet. Would love to hear from you on how to fix it please. Thank you very much.
Doesn't it make more sense to use a trigger to check if they can interact? That way you don't need to compute distance and orientation. Instead it's if they're in or out of the trigger.
Hey I have a question in the first person mode and character I already have some stuff there I'm new to this stuff and when I try to add Even Begin Play on the FirstPersonCharacter it doesn't let me because it is already used by another widget. Any solutions?

Hey Ryan, I’m still stuck on how I’d make my Guard not see the player if they’re in Stealth Camo, are you able to do a quick video on it please? coz I can’t find anything on RUclips 🤔
You can use a boolean value, like "can be seen" on the player, so in your npc logic, have it ask if this value is true or false before deciding how to react to seeing the player.
hello, im using this dialogue for trying to make a game, but there a issue i can't solve, which is picking a choice, it work at first but later it would not let me pick any of the choice ive made afterward. like its locked or something? for example, ive been going through three long dialogue with choice which worked, but later it won't let me pick anything after. but sometime it worked after i restart, but later the other dialogue choice won^t work. the mouse appear, but when i hover around the choice, the hovering dont change color, or the button doesn't work when clicking, as if there a invisible wall above it. using unreal engine 4.27.1 and 4.27.2.
I am using 5.3.2 unreal and I was having trouble with the “remove from parent” in the heads up display widget. But I was able to fix it by adding a “is Valid” with the question mark to false and connected the “message widget” to the input object. Then connected the “is valid” to “remove from parent” and it worked. I hope this helps anyone with the problem. (Edit: everything else in the video works very well just I had trouble at that part)
İ may be a little late but there was an another engine for developing visual novels, it was called renpy if i recall correctly. İ think renpy was way too better than unreal when it comes to visual novels, so i recommend you to give it a shot
Im having an issue, in my interact check the display messege node has a heads up display object reference but my player hud has a user widget object refference. I'm wondering of anyone has a solution for this thanks ^^
If you're using a collision box of some kind to do this then you are probably using the OnBeginOverlap event. Just use OnEndOverlap event to remove the message.
Everything here works perfectly, but I'm getting an error each time that says "Accessed None trying to read property MessageWidget".

Thing is, I followed this tutorial step by step and for some reason, the message "Press E to Interact" does not show up and I really don't know why. but I am actually using an older version of Unreal Engine specifically 4.17.2, I really wonder if the version has something to do with why it won't work for me.

Have you clicked the "Show Message" Boolean box within the "Display Message" Event within the Interact Check function of the Player Character? If unchecked, the "Press E to interact" will not show. It was one of the very last steps.

Ok yeah i have a problem. im not using a rotation based movement system. so the sphere trace does not rotate with the direction im walking. and i am getting an error when i try to interact with the npc. "Accessed none trying to read Property PlayersHUD". can you help me?
Not sure about the first half of your question, but I ran into the same "Accessed none" error. To fix it: in your HeadsUpDisplay widget blueprint, on the false leg of the Branch node, make the reference to the Message Widget a validated get and connect Is Valid to Remove from Parent. That way it only tries to remove it if it actually exists.
@@mccarthyjl it is a sprite based movement system. it should work because i am "flying" and based on the key i press the sprite changes. it should work how it is now but it doesnt. also the fix doesnt do it for me.
@@altereddev8117 fixed it by putting a delay either infront or behind of the cast to gamemode. the rotation i fixed by just using a static line trace that tracey every direction at once or basically everywhere around the character
I'm not a programmer (I'm 3D artist :D but I love the concept that I can make my own game with your tutorials!) but isn't that trace sphere going to kinda... "lock" interactable actors you (and me) created in your (great!) inventory system tutorial and make them "unachievable"?
If anyone ever has the problem I did, here's a solution. Problem: I couldn't access "DisplayMessage" function inside of my HUD from The Player Pawn Blueprint's "Interact Check" function, so I tried to cast the variable inside of my player character referencing the HUD to cast as my HUD Blueprint and then I hooked it all up. It gave constant error messages saying something like "Accessed NONE while trying to CastToW_HUD" My Solution: My HUD variable reference was starting from my GameMode, and both were coming out as TYPE: User_Widget I re-did them so they both were of type W_HUD (my custom widget for the HUD), and then I no longer needed to cast in the interact function, as my reference to the HUD was now the actual HUD and not a general User_Widget and everything became solved. This is probably some error I made along the way that's totally my own fault, but maybe it can help someone else. Peace and love
even thought the print string works when the sphere trace hits the npc im getting "Accessed None trying to read property PlayersHUD" like 10,000,000 errors and the interact widget wont show
@@RyanLaley seems like nothing is working followed the tutorial exactly positive i didnt miss anything. Maybe it might be engine version. I am making a project with paper 2d character in 3D enviroment camera is in fixed position.
Is there a way where the interact message goes off after you have interacted with it? Also how will you change the camera view to the NPC view like the one in this video: ruclips.net/video/3uHQRpK2jkE/видео.html with the blueprints that was used in the video above? I hope my questions make sense and I hope you will be able to answer them. Thank you in advanced.
@@porainIDK if this is too late, but try changing the game mode overview. My project had like 3 third-person game modes but only the one in which I put the blueprint worked. After that go into project settings and set the working game mode as default so that it always uses that and never switches.
It is a bit complicated to explain but essentially instead of deleting the child every tick you take the canvas and get all of its children, then you run them through a for each loop and test if the equal the message you want to delete that is supposed to be there, but really is not. My tree looks now as follows: after the Branch that checks the message another branch. The condition you want to check is "has Any Children?". If this is true you get all the children with the function "get all children". THis returns an array you put in a for each loop. The array element outputted you check with == message widget. If this is true you have the message on screen. The "loop body" of the for each loop goes into another branch. If this is true we have a children and we also have the message we want to delete. From there just insert the "Remove from Parent". And also set the message widget to nothing, so it is cleared up for later use. That was my ""FIX"" . It is actually way better tbh as you can check for any message on screen and delete it accordingly. Also a lot safer as you dont get errors like "has no children to delete" which is what we expirienced.
Hi anybody has any solution for this error? Been trying to fix it for hours Blueprint Runtime Error: "Accessed None trying to read property PlayersHUD". Blueprint: ThirdPersonCharacter Function: Interact Check Graph: InteractCheck Node: Display Message

It would be great to have a JRPG dialogue system tutorial. One where i can see character name, message and the picture of the caracter. All tutorials are going for the same way :(
You can't have everything done for you, you have to be able to think for yourself otherwise you won't get far making games. Adding in the features you specifically listed really isn't difficult, just add a new part to the dialogue widget like text, apply a variable you gave that NPC (e.g. name) to that part and fiddle around with it and you'll get there. I know this comment is 5 months old but good luck with whatever you're doing now anyway :)

This is the first negative youtube comment I've ever left (true story), but Ryan, can you PLEASE start naming things in an organized and clear manner. It would really help out your viewers, especially new ones. On your qust making tutorial you named almost every variable, widget, and object reference some variation of "quest" which makes unpacking what the hell we're actually doing extremely difficult. Just some constructive feedback; I do enjoy your channel but the disorganized naming conventions make it nearly impossible to actually learn anything.
Problem with a lot Ryan's tutorials is he never fully explains the reason for doing things bit by bit, Which means you never learn, and just are really copying his work, rather than learning.
honestly man... can you please be a little more organised in your video structures in future? You are extremely hard to follow when shit hits the fan and I'm trying to backtrack your tutorials for an answer as to what I did wrong. Just make a script or a step by step process for yourself to follow when you record so you don't bounce between everything the whole time... It's really frustrating trying to comb through 25 min long videos just for a box I misticked or whatever. Takes me an hour to find what I did wrong instead of 10 minutes.

To fix it: in your HeadsUpDisplay widget blueprint, on the false leg of the Branch node, make the reference to the Message Widget a validated get and connect Is Valid to Remove from Parent. That way it only tries to remove it if it actually exists.
What kind of movement are you using? The sphere should be attached to the skeletal mesh.
@@mccarthyjl it is a sprite based movement system. it should work because i am "flying" and based on the key i press the sprite changes. it should work how it is now but it doesnt. also the fix doesnt do it for me.
@@alex_sophie Hey did you fix it? I've got the same problem...
@@altereddev8117 fixed it by putting a delay either infront or behind of the cast to gamemode.
the rotation i fixed by just using a static line trace that tracey every direction at once or basically everywhere around the character
How could I make it so that the "Press E to interact" message appears above the NPC's head instead of on the screen?
Add the interact widget as a component to the npc bp in world space
@@Desdemniae Thank you!! Don't know how simply doing that went completely over my head lol 😅
I'm not a programmer (I'm 3D artist :D but I love the concept that I can make my own game with your tutorials!) but isn't that trace sphere going to kinda... "lock" interactable actors you (and me) created in your (great!) inventory system tutorial and make them "unachievable"?
Use multitrace. It returns an array of all actors hit. So you can do a for each loop and get the highest priority target.
@@RyanLaley You are the best!
prees e to interact is not showing up help
Hmmm, when I connect DisplayMessage to false for both branches I get an error for the position. Can anyone help?
For anyone in the future this was in the comments below but it helped me out i.gyazo.com/964bbf682fda114498ff6864329fd128.png ??
If anyone ever has the problem I did, here's a solution.
Problem: I couldn't access "DisplayMessage" function inside of my HUD from The Player Pawn Blueprint's "Interact Check" function, so I tried to cast the variable inside of my player character referencing the HUD to cast as my HUD Blueprint and then I hooked it all up. It gave constant error messages saying something like "Accessed NONE while trying to CastToW_HUD"
My Solution: My HUD variable reference was starting from my GameMode, and both were coming out as TYPE: User_Widget
I re-did them so they both were of type W_HUD (my custom widget for the HUD), and then I no longer needed to cast in the interact function, as my reference to the HUD was now the actual HUD and not a general User_Widget and everything became solved.
This is probably some error I made along the way that's totally my own fault, but maybe it can help someone else.
Peace and love
So tutorial doesn't work for me
even thought the print string works when the sphere trace hits the npc im getting "Accessed None trying to read property PlayersHUD" like 10,000,000 errors and the interact widget wont show
Sounds like you PlayerHUD referenced hasn't been correctly set. Make sure it is on a begin play event
@@RyanLaley seems like nothing is working followed the tutorial exactly positive i didnt miss anything. Maybe it might be engine version. I am making a project with paper 2d character in 3D enviroment camera is in fixed position.
Is there a way where the interact message goes off after you have interacted with it? Also how will you change the camera view to the NPC view like the one in this video: ruclips.net/video/3uHQRpK2jkE/видео.html with the blueprints that was used in the video above? I hope my questions make sense and I hope you will be able to answer them. Thank you in advanced.
for some odd reason the 'remove from parent message widget' is cauysing me errors.
Thank you！
@@a.pustovitovsky I had such problem, but I can't understand your answer

Hi, I can't cast HeadsUpDisplay to the ThirdPersonGameMode (the cast fail)... does someone knows why?
Never mind, fixed it
@@altereddev8117 Hi，I got the same problem! Can you tell me how you fixed it?
@@porainIDK if this is too late, but try changing the game mode overview. My project had like 3 third-person game modes but only the one in which I put the blueprint worked.
After that go into project settings and set the working game mode as default so that it always uses that and never switches.
Also have video problems, green screen
Mmmmh I don't understand why it show a thousand of display message and never remove it :/
It is a bit complicated to explain but essentially instead of deleting the child every tick you take the canvas and get all of its children, then you run them through a for each loop and test if the equal the message you want to delete that is supposed to be there, but really is not.
My tree looks now as follows: after the Branch that checks the message another branch. The condition you want to check is "has Any Children?". If this is true you get all the children with the function "get all children". THis returns an array you put in a for each loop. The array element outputted you check with == message widget. If this is true you have the message on screen. The "loop body" of the for each loop goes into another branch. If this is true we have a children and we also have the message we want to delete. From there just insert the "Remove from Parent". And also set the message widget to nothing, so it is cleared up for later use. That was my ""FIX"" . It is actually way better tbh as you can check for any message on screen and delete it accordingly. Also a lot safer as you dont get errors like "has no children to delete" which is what we expirienced.
Nothing shows when I walk up to the NPC
Hi anybody has any solution for this error?
Been trying to fix it for hours
Blueprint Runtime Error: "Accessed None trying to read property PlayersHUD". Blueprint: ThirdPersonCharacter Function: Interact Check Graph: InteractCheck Node: Display Message
For those wondering, in your Interact Check function, near the end, right click and change the GetPlayersHUD to a validated Get and connect IsValid into the Display Message Node and give it a shot.
@@KepperSnapper Hi. I dont quite understand the "change GetPlayersHUD to a validated Get and connect IsValid".
I have like 1200 errors saying accessed none PlayerHUD. Does anyone know how to fix. I follwed the tutorail all the way through.
I dont know how to solve this as well. there is a solution in one of the comments below but I cant understand what hes saying.
@@KepperSnapper yeah it is a bit complicated. I'm still trying to figure out, but i can't.
@@meathook4153 Hey try this. In your Interact Check function, near the end, right click and change the GetPlayersHUD to a validated Get and connect IsValid into the Display Message Node and give it a shot.
Convert your references to the message widget in the HUD (when you go to remove the widget from the parent) to a validated get
@@wildfire_writer Thanks, I respect that you commented this 2 years later.
It would be great to have a JRPG dialogue system tutorial. One where i can see character name, message and the picture of the caracter. All tutorials are going for the same way :(
You can't have everything done for you, you have to be able to think for yourself otherwise you won't get far making games. Adding in the features you specifically listed really isn't difficult, just add a new part to the dialogue widget like text, apply a variable you gave that NPC (e.g. name) to that part and fiddle around with it and you'll get there. I know this comment is 5 months old but good luck with whatever you're doing now anyway :)
@@Rndm9 "you can't have everything done for you". Thanks, captain obvious. I know that. Just i didn't find any help and for a beginner it's too hard sometimes to make something new. Even if you say it's easy.
Anyway, thanks.

IF I try to put these inputs for a firstpersoncharacter this tutorial simply does not work at all, no messages on the screen, even if the npc print string works perfectly. Jesus...
nevermind, there werre a missing exec link in the gamemode, fuck there are so many chance to forget some link with this software and the software does nothing to warn you, epic should really do something about this.
@@Marco-ve2kk im having the same exact problem how did u get it working?
This is the first negative youtube comment I've ever left (true story), but Ryan, can you PLEASE start naming things in an organized and clear manner. It would really help out your viewers, especially new ones. On your qust making tutorial you named almost every variable, widget, and object reference some variation of "quest" which makes unpacking what the hell we're actually doing extremely difficult.
Just some constructive feedback; I do enjoy your channel but the disorganized naming conventions make it nearly impossible to actually learn anything.
All I'm getting is a green screen :/
Just download the video with for example 4K Video Downloader. It's fine.
Problem with a lot Ryan's tutorials is he never fully explains the reason for doing things bit by bit, Which means you never learn, and just are really copying his work, rather than learning.
honestly man... can you please be a little more organised in your video structures in future? You are extremely hard to follow when shit hits the fan and I'm trying to backtrack your tutorials for an answer as to what I did wrong. Just make a script or a step by step process for yourself to follow when you record so you don't bounce between everything the whole time... It's really frustrating trying to comb through 25 min long videos just for a box I misticked or whatever. Takes me an hour to find what I did wrong instead of 10 minutes.
