UE5 | Ultimate Dialogue System - Tutorial - Pt1 

It's difficult to say why it's not working specifically but the first thing I would do is add a print string to the button press/release to make sure it's actually firing. If it is, you need to follow the functions that are called to make sure it calls the relevant things. It should update the dialogue progress and call the dialogue again. (To refresh)

Just went over all the video and spot a connecting wire missing in the Update Option function. Well! Well!Now it work, amazing!!!

You could add the dialogue component to the player controller and have it start the dialogue on begin play.

@@mpattym Got you. I’ll give this a try later on today. Thank you

When you use the 'Add Dialogue' node, connect a 'Play Sound' node to the 'Updated' output and select the sound you want to play. It might however be worth adding an audio component to the NPC that you use to play the dialogue so you don't get overlapping dialogue playing at once. It would just be a case of updating the sound the audio component plays.

Near the beginning of the tutorial, I show you how to create the enum.

Sure, when I mentioned the 'add dialogue' node, I was referring to adding the play sound node inside that node after the bit that updates the dialogue. You can always join my discord and I can share a few screenshots of how I set it up in my more complex dialogue system when I get some time. discord.com/invite/g5ZWEAT2

@@mpattymoh, i found my problem. I did not change the state of the return node in the add dialogue function to updated 🙃But anyway, thank you for the quick answer!:)

I've got same issue! did you find a fix?

I found the fix. open 'W_DialogueOption' then go to 'Graph' and make sure on 'Update Selected Option' it goes 'Owning Dialogue Component = Target' then 'Dialogue Index = Progress Index' then 'Option Index = Option Index'... I had Dialogue index and option index mixed up lol.

That is an input for the function. The function is inside the dialogue widget that is used to update the dialogue text and show the options (if there are any). We pass the Dialogue Index to the widget (hence the name of the input var) so the widget know what dialogue index it needs to update when an option is selected.

@@mpattym Thank you very much.

I've not made anything for VR for many years but I would imagine the only major difference would be having the Dialogue show in the world as opposed to being placed in screen space. It shouldn't be too difficult to make this work with VR, you'll just need to have the widget display inside a widget component that's attached to the player. Of course doing anything in VR does have an element of trial and error to ensure its easy on the players eyes to view and read. Hopefully, this will point you in the right direction.

I do yes. :)

Make an enum for your different emotional stats, in the dialogue function add a switch on enum based on your enum. If you add the enum to your character as a var, you can then get it from your dialogue and plug it into the switch node.

@@mpattym Can you show how to do that?

@@ahmadruslanovich739 brother, get the enum and then do a switch on it and base on the answer, play a anim montage.

I dont think they are talking about animation. Like Rune Factory, that has facial expressions thats an image change on the Dialogue widget. If not, its a question I have anyways. and there are no tutorials on it so this creator could get lots of traction to their channel if they did a tutorial on how to make an image that changes along with set dialogue. @@youngjojo3052 @mpattym

I figured it out. It took me 2 full days... but I got it - Make New Enum with all the emotions (I called mine Enum_Expression_Image) -In W_Dialogue Make a New Function called SetImage -In W_Dialogue in Designer, the image you wish to change, Make it a variable (I named mine EmotionalStateImage) -In W_Dialogue in Designer go to the appearance in the details panel and "bind" the -brush to EmotionalStateImage. --In SetImage Make "Switch on Enum_Expression_Image". --In SetImage Function (Set)-"EmotionalStateImage" to each expresion with the desired image -In W_Dialogue add SetImage to UpdateDialogue -In AC_Dialogue_Base Select the fist node in Add Dialogue and go to the Inputs in the details tab and add input. set it to Enum_Expretion_Image. It will then show as value on the Add Dialogue Node (Called Expression) -In AC_Dialogue_Base Add SetImage to the Add Dialogue Function after true on the branch and connect the Expression to Expression -In AC_Dialogue_Mouse In Dialogue Function the Add Dialogue component should have an Expression that you can then set as any expression from the Enum and when you talk it should be able to see the expressions how you set it up in the Widget. Let me know how you go. I tried to be as clear as possible @@ahmadruslanovich739

Yes, it's set up to use mouse clicks so it should make a difference if you're using 1st or 3rd person.

@@mpattym Awesome

With a few tweaks you could probably make it work, assuming you're not actually wanting the player to have options. I'm not too familiar with the level sequencer so I can't say for sure though.

That would depend on what you mean by integrated. If you just want the behavior tree to open up the dialogue, I don't see why not. You would just make a task that gets the controlled pawn and gets the dialogue component from it. Once you've done that you can call any of the functions from it.

I'm sorry but I don't provide a download for this system. If you're not wanting to make it yourself, you can always checkout 'Project Sunrise's on the UE marketplace. It includes a revamped and overhauled dialogue system that follows the same concept. (Amongst other systems)

Yea, it should be possible. You can use the updated branch to trigger a move to event. However, there isn't anything in the system to delay the next dialogue showing until the move has completed.

@@mpattym can it be just a pup up widget with options and movement be made via waypoints?

@@isonavi23 I don't see why not but if your wanting complex movement such as way points, you might need to create a separate system that moves to character to and from way points that you can then call from the dialogue system.

@@mpattym I don't seem like understanding how to actually implement this. Could you help please? For example with function like ai move to or move to actor/location. And how to connect it to "updated" branch

@@isonavi23 When you use the add dialogue node it has an enum output that's determines the update state, using the switch on enum node, you will get the pass through and updated exec pins. It would just be a case of getting the owner of the dialogue component and using the AI move to node (connected to the Updated exec pin) on the part of the dialogue you want them to move.

:( I think we've all be there. I spend half an hour debugging an issue with an NPC not moving only to realize I set their max walk speed to 0.

@@mpattym I mean, valid point, but it was on the video, and it wasn't ever shown deleted

MAN WTF hahahah 2h of my life checking each frame, every nodes, every numbers in the 3 videos 19:16

At a guess I would say you've not correctly made the enum. The tutorial shows every step starting with the third person template. Be careful when skipping through as you might miss steps.

@@mpattym I watched the video 3 times from the first second but nothing I can not find the passage of the enum

@@matteospo6426 the enum is created at the 5 minute mark.

@@mpattym tnks very much i love you

Not out the box, but with a few small tweaks it shouldn't be too difficult. I would add a bool var for 'bDisplayName?' And have this set to false to begin with. Then where the name is passed to the widget, use a select node to return either something like '????' or the name in the name var.

It seems you skipped the bit where I make the enum in the video. ;) It's just a custom enum.

If you provide a description of the issue, I can see if I can help.

@@mpattym I watched 3 of your videos and I applied the video stop and stop, but when I interact with the last part of the videos, it does not bring up the dialog widget. I checked all "creating widget" parts but everything is the same with you. I couldn't find the cause after all. Actually, I can share screen or etc when are your free if is it okay for you?

@@CosmosisTR the first you would need to due is debug the open conversation function as this created the widget. You can add a print string or break point to see if it gets to that point. If it doesn't, check how you're interacting with your NPC to make sure they're receiving the interact. If it does make it to the open conversation, check the create widget node is creating the correct widget and is added to the viewport.

@@mpattym Now it works until creating widget, but creating only "W_Dialogue widget" not updating dialogue on AC_Dialogue_Base. I checked all nodes on base document but everything is same.

I'm sorry but I don't provide the completed project files for my tutorials.

Thank you for letting me know but yea, it looks like they've rehashed my dialogue system and attempting to pass it off as their own.

Rewatching the tutorials I realized you actually explain that error happens. You didn't say if there's any fix or a way to change variables and stuff like that between dialogue phases, instead of on the update. Thanks on advance!

I found a fix: Just adding an empty "AddDialogue" node between the desired ones, and setting all the needed variables before calling the good dialogue. It may not be a good way to work normally, but it's doing the trick in a few situations.
