Official Dialogue System + Timeline track

@cirocontinisio the video you linked didn't works.

 

I'm new to reviewing pull requests in Unity, If i want to go and look at either @Caiuse or @dkaloger 's pull requests and check them out in Unity - how do i do that? I tried checking out the repository fork but that brought me to the latest commit rather then the PR 's latest commit which caused script complation errors.

 

I just found out this open project when trying to find some reference to build DialogueSystem for my game,
then got inspired to build DS with Timeline.

So here it is... I comeback to return the favor

About my DS:
Main new feature:
- It can wait for user input. (wait or not depend on the DialogueController. Timeline is just some extension from this controller).
- Can move object (like camera) when waiting for user input.
- Will jump timeline to proper clip if player input is faster than the timeline.
- Can play the timeline in preview mode (with updated text).
Improvement (maybe) from our current implementation:
- No need to initialize DialogueClip with dialogue id one by one (Our current implementation).
My implementation just need the last id from DialogueData (SO that holds message, actor, etc) that you want to cut/hold from (the main difference with the Caiuse implementation).

(for better understanding from what I meant, you can see the video linked below)

Do my dialogue system suit this project? and... do anybody has been working for this?

If it's suitable and no one has been working for this yet... how to contribute?
this is my very first time. I usually a lonely coder ehe

I mean, should i fork the @Caiuse repo or from UnityTechonologies repo? (since the PR isn't merged yet)

 

Hi @Soundguy ,
yes, the video @cirocontinisio didn't work in my laptop too.
But i believe, the video he meant is this:

---------------
I'm still new about this kind of stuff too (working with git)
But, I'll try to help...

about your issue with git,
if you fork from UnityTechnologies repo, you can't see the PR latest commit because that isn't merged yet.

try to fork directly to repo that you want to test. About compilation error, try to use the same Unity Verison.
I have try the master branch from UnityTechnologies repo and Caiuse repo with no problem (today)

 

If you only have a few tweaks to the code @Caiuse has in that PR, fork from that and submit a PR to that branch for review. If it’s completely different from that implementation, fork from the main Unity repo and submit a PR that way.

Either way, that art style kinda fits the concept art for this, nice job.

 

That's good to hear.

Aight, gonna work on it this week.

 

Hello, I want to ask, can we use others people code?

I'm making custom editor for the dialogue SO, so that the list of the conversation can be re-arranged.
I actually can make it my own, but... I believe using other people code is more easier has more feature.
I'm going to use ReorderableList:
https://github.com/cfoulston/Unity-Reorderable-List/blob/standalone/List/Editor/ReorderableList.cs

 

You have to check the distribution license of other people's code because this is a free and open source project. If they have any kind of restrictions we cannot use it. Looks like that one has an MIT license, which may be okay, but let's ask @cirocontinisio just in case.

 

I have made PR guys, please review it here:
https://github.com/UnityTechnologies/open-project-1/pull/135

*No, answer from Ciro,
But I believe it's okay, so... I use that ReorderableList.cs

 

I had an issue when pulling this update in, but i realized it was some local issue with my git setup. PR is all good.

However, when i was digging around I saw some stuff:
1. We are subscribing and unsubscribing to input events using anonymous lambdas which is not good (https://stackoverflow.com/questions/1362204/how-to-remove-a-lambda-event-handler)
2. We are also subscribing to `activePlayableDirector.stopped`, but never unsubscribing?
3. We have an existing input reader. I think it would be a good idea to extend the input reader to handle these requirements, rather than bypass it. This is actually why the method signature on the handlers in the dialogue manager do not line up with the event signature.

I put in a small PR to asdress these issues.

 

@cirocontinisio
Want to report, timeline dialogue is not pausing at the end of the last clip. Is that considered a bug?
You leave comment in the code. Is that a note or you also don't know why it's not working? ehe

Also, I have suggestion, a small feature:
Current implementation cannot advance dialogue fast enough, you need to wait till end of clip to be able to advance.
How about we make timeline jump to end of the clip while we are still at the beginning or middle of the clip.
How's that?

 

Seems like we should probably stop the track once the dialogue is over. I can roll this into my event subscription fix.

I don't think it would be difficult to implement... Kinda reminds me of how the witcher does cutscenes/dialogue. I like it! =)

 

I am not very familiar with authoring cutscenes. I am assuming that the feature would work like follows.

Scenario 1:

1. camera pans over town for 3 sec
2. user wants to jump to next camera shot
3. user hits space
4. 2 seconds of pan is skipped, camera is now at the next shot in the timeline

Scenario 2:

1. user has already seen the cutscene, wants to skip entirely
2. "holds" skip button
3. entire cutscene is skipped

does that sound reasonable? Or are we not 'splitting' up camera shots in a way that would enable this? I think this is a pretty standard feature for most RPGs

Also re dialogue: do we currently have skipping coded into the dialogue flow? I think this is a bit higher priority than skipping in a cutscene.

 

I see, that makes perfect sense. I agree, we should wait until animations are in before we start thinking about skipping dialogue lines. And I agree, it quickly gets messy if player choice is involved at all. Definitely do not think we should be skipping the entire dialogue in that case.

So my take is- skipping dialogue lines is only something we should think about once text animations are in. No skipping of entire dialogues (ever).

 

Sorry, maybe i misrepresented this. I think it is a 'nice to have', a 'no-rush' feature. I do not think this is a priority. It is something i've seen as the standard for many other games, so that was why I brought it up. I think it is good to document this and store it as work for later.

 

By advancing fast, doesn't mean you instantly see the next DialgoueClip.
That's only mean jumping the Timeline to the end of currently played DialogueClip.

If there is a hole between DialogueClip (like we make the camera showing something to the player),
that still can't be advanced (since in my proposition, advance dialogue only available if playhead is on a DialogueClip).

Yeah, it's not really needed right now, but I just want to make the cutscene more responsive.
Maybe after we've done branching, how's that?

btw, here is scenario that make cutscene system is 'unresponsive':
1. Designer want to show "Hello" text (in DialogueLine).
2. The designer make a DialogueClip without changing the default length (default length is about 5 second long)
3. The designer bind the DialogueClip with the DialogueLine ("Hello" text).
4. Let say player read "Hello" text only about 1 second.
5. The next 4 second is an awkard moment of silence XD.

If we able to advance dialogue anytime (even when playhead doesn't reach the the end of the a specific clip),
that will make the game more responsive.

And yeah, about skipping dialogue, it's kinda 'complex' to implement.
But... if we still have time, and want feature similar to that, we maybe just need to set Timeline speed to 1.5 or 2 while auto advancing any DialogueClip that occur (except if there's a choices).
So, even if there is a choices, player won't miss and we don't need to make 'complex' algorithm to solve that. (Not a skip button, but fast forward).
How's that?

 

btw, I'll try to work on branching feature next week,
Let see what I can come up with

 

Hi Guys, I'm new to this open project. I would like to get involved in the dialogue system work stream - is there anything I need to read to get up to speed apart from what is in the roadmap? What system is being used to display dialogues? how are tasks organised?

 

@Emikey1
Dialogue and cutscene system is explained in the 3rd livestream:

In that video, they also explain how to contribute, what to do next, and more.

 

Ohh, and also
some task that are outside of road map but will need to do (if I remember correctly) is:
- Add special formatting to the font (make the text bold, change the text color)
- Displaying dialogue in preview mode of Timeline
(explained in the video as well)

 

Many thanks Sarai - will check out the video as a first step

 

@Sarai - Hi, I watch the video about the dialogue and cutscene managers. It looks like the dialogue manager can be used independently so is that the best place to start? If I want to play with it, is it easy to get up & running in a separate project?

 

@Emikey1
Yep, they are independent from each other thanks to Ciro.
So yeah, it's easy to get up and running in separate project.
Why don't you try it out?

 

@Sarai will do this week.

@cirocontinisio - how will individual systems in this game be documented? I presume only a few people will be able to understand the E2E project? Therefore people may come to this project in the future trying to get inspiration for a particular issue they are trying to solve - e.g. I'm interested in adding dialogue to a prototype I'm developing as part of the Junior Programming Course with unity ..... if this is something of interest, I could try to document the dialogue manager .... is there an exemplar for how systems should be documented to make them easier to re-use in other projects?

 

I saw a card on codecks stating "Branching Dialogue". What is this?

 

Giving the player more than one option to choose how they respond to other characters, and allowing the dialogue responses to change based on what the characters say. This makes it so the dialogue isn't linear (i.e. player says one thing, other character says one thing back, player only has one thing to say back again, etc).

 

I have made PR about branching, I also made quick video about it.
Check it out here:
https://github.com/UnityTechnologies/open-project-1/pull/195

Feel free to improve or made it from scratch if you have better solution.

 

I was going to mention that PR and had a feeling this username was aligned with that, just didn't want to be wrong.

 

Hahaha, you have good feelings XD

 

No, you didn't understand. I wanted to know what is Dialogue Branching

 

I answered what the term is referring to in the card, and @Sarai gave the link to the PR describing an implementation in this project.

"Branching dialogue" and "dialogue branching" are the same thing, is there something else we missed?

 

I'm looking forward for it!

 

Nice ! Can we already take a look at it somewhere ? EDIT: Just saw the QuestSystem branch !

Also, does this Quest system need its own thread ?

 

The links of the Dialogue and Cutscenes Systems can't be clicked on the Wiki page

 

I'm very satisfied with the achievement of using the timeline as a dialog system. First Timeline let you make custom markers and custom tracks. Coming from the Macromedia Flash MovieCLip system with GoTO, GoTo, and Stop, GoTo and Play give me an idea of control of the timeline not just in a sequential way. Custom notification, events give you the option to communicate with StateMachine (Mecanim) etc...

May the Forge be with you!

 

It seems like the dialogue branching can't use with Timeline in this openProj? What if the dialogue has audio and faceAnimation, they should stay in timeline. And normally audio can be skiped, then move to next dialogue.

 

Better develop your own dialogue and quest system, because the one in UOP1 is too linear.
