How to Continue Conversations

[Salja]

I use master audio, there is a way to display the continue button when the audio has finished playing?

[Tony Li]

Yes. You'll use a short script.

Assuming you're using a PlaylistController to play audio (e.g., the Dialogue System's MAPlaylistClip() sequencer command), on the MasterAudio GameObject define a custom event named, for example, "SongEnded".

On the PlaylistController GameObject, configure the Song Ended Event to call the SongEnded event:

Add an ICustomEventReceiver script to the Dialogue Manager that handles the SongEnded event. Something like the script below. This script hides the continue button, waits until Master Audio sends a SongEnded event, and then shows the continue button.

HideContinueButtonUntilSongEnds.cs

Code: Select all

using UnityEngine;
using PixelCrushers.DialogueSystem;
using DarkTonic.MasterAudio;
using System.Collections;

public class HideContinueButtonUntilSongEnds : MonoBehaviour, ICustomEventReceiver 
{
    private bool songEnded;
    
    // Dialogue System calls this method just before showing a subtitle:
    void OnConversationLine(Subtitle subtitle)
    {
        StartCoroutine(MonitorSong(subtitle)); // Start coroutine to handle continue button.
    }
    
    IEnumerator MonitorSong(Subtitle subtitle)
    {
        songEnded = false;
        var ui = DialogueManager.dialogueUI as AbstractDialogueUI;
        yield return new WaitForEndOfFrame(); // Let dialogue UI set up subtitle.
        ui.HideContinueButton(subtitle); // Hide continue button until song ends.
        while (!songEnded) { yield return null; } // Wait for song to end.
        ui.ShowContinueButton(subtitle); // Song ended, so show continue button.
    }

    // Methods to satisfy ICustomEventReceiver:    
    void OnEnable() { RegisterReceiver(); }
    void OnDisable() { if (MasterAudio.SafeInstance == null || MasterAudio.AppIsShuttingDown) return; else UnregisterReceiver(); }

    public void ReceiveEvent(string customEventName, Vector3 originPoint) {
        if (customEventName == "SongEnded") songEnded = true;
    }

    public bool SubscribesToEvent(string customEventName) {
        return string.IsNullOrEmpty(customEventName)) ? false : _eventsSubscribedTo.Contains(customEventName);
    }

    public void RegisterReceiver() {
        MasterAudio.AddCustomEventReceiver(this, transform);
    }

    public void UnregisterReceiver() {
        MasterAudio.RemoveCustomEventReceiver(this);
    }

    public IList<AudioEventGroup> GetAllEvents() {
        var events = new List<AudioEventGroup>();
        for (var i = 0; i < _eventsSubscribedTo.Count; i++) {
            events.Add(new AudioEventGroup {
                customEventName = _eventsSubscribedTo[i]
            });
        }
        return events;
    }
}

Another way to do this is to send a sequencer message when the song ends. Then you can do most of the work inside the Sequence instead of the script. For example, the Sequence could be:

Code: Select all

SetContinueMode(false);
MAPlaylistClip(entrytag);
required SetContinueMode(true)@Message(SongEnded);

The advantage of this is that you can have some nodes that don't play Master Audio clips. The script would be:

SequencerMessageWhenSongEnds.cs

Code: Select all

using UnityEngine;
using PixelCrushers.DialogueSystem;
using DarkTonic.MasterAudio;
using System.Collections;

public class SequencerMessageWhenSongEnds : MonoBehaviour, ICustomEventReceiver 
{
    void OnEnable() { RegisterReceiver(); }
    void OnDisable() { if (MasterAudio.SafeInstance == null || MasterAudio.AppIsShuttingDown) return; else UnregisterReceiver(); }

    public void ReceiveEvent(string customEventName, Vector3 originPoint) {
        if (customEventName == "SongEnded") Sequencer.Message("SongEnded");
    }

    public bool SubscribesToEvent(string customEventName) {
        return string.IsNullOrEmpty(customEventName)) ? false : _eventsSubscribedTo.Contains(customEventName);
    }

    public void RegisterReceiver() {
        MasterAudio.AddCustomEventReceiver(this, transform);
    }

    public void UnregisterReceiver() {
        MasterAudio.RemoveCustomEventReceiver(this);
    }

    public IList<AudioEventGroup> GetAllEvents() {
        var events = new List<AudioEventGroup>();
        for (var i = 0; i < _eventsSubscribedTo.Count; i++) {
            events.Add(new AudioEventGroup {
                customEventName = _eventsSubscribedTo[i]
            });
        }
        return events;
    }
}

Brilliant and thorough FAQ, Tony!

[Strig]

Hello, Tony! Nice FAQ thread!

In my Dialogue Manager, I have set the key that starts the conversation as the same one that continues it, for the sake of consistency. Like one would use the "A" button as a general "confirm" in a dialogue.

Thing is: when I press the button to continue, the system gives me an alert becuse it's "unable to start a conversation" due to one already being active. And this happens every single time I press the key to continue.

Out of curiosity: can I stop this check altogether? Would it help with efficiency? Or should I just disable alerts in the Dialogue Manager?

[Tony Li]

Hi,

Use a Dialogue System Events component to disable whatever component listens for "A" to start the conversation. For example, in DemoScene1 the Player GameObject has a Dialogue System Events component whose OnConversationStart() event disables the Selector. The OnConversationEnd() event re-enables it.

Hi Tony.

How do I hide the Continue Button from inside the dialogue tree, temporarily? Given that my Continue Button Mode is set to Always.

I'm making a node invoke a separate window via the Script field, and I wanted the dialogue tree to wait for the result of that window (through user input). So I want to prevent the player from accidentally advancing the dialogue by disabling/hiding the Continue button.
I tried SetContinueMode(false) on the Sequence field. It hides the button, but it causes the dialogue to advance automatically.
I also tried to disable the Continue Button gameObject via C# when the window is enabled, but the button is apparently reactivated right after, because of other stuff.

[Tony Li]

Hi,

Try setting the Sequence field to something like this:

Code: Select all

SetContinueMode(false);
WaitForMessage(SeparateWindowClosed)

This will keep the sequence active (and thus the conversation stopped at that dialogue entry node) until the sequencer receives the message string "SeparateWindowClosed".

When the other window closes, use a line of C# code to send that message:

Code: Select all

Sequencer.Message("SeparateWindowClosed");

Works great. Thanks, Tony!

Happy to help!

Hi,
is there a cleaner way to trigger the Continue function through touch? I don't like the giant transparent button very much
It would be very appreciated a method just as StartConversation() (ex. Continue()).
