Unreal Engine 4 Tutorial - Advanced Dialogue Pt.1 - Interaction

[@BrianHamil]

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.

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.

[@TheGrimmy]

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 :)

[@obbymusic744]

How

[@kevinaccettarobles5042]

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.

[@saif0316]

what does this mean? sorry, I'm kinda lost with what you said ..

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.

[@SakakiHiroshi]

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!

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.

[@mccarthyjl]

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.

[@BrianHamil]

What kind of movement are you using? The sphere should be attached to the skeletal mesh.

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

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.
