how to make Character greys out when not speaking while staying on scene?

[CovetHiss]

I am trying to implement the design of when there are 2 or more characters on the scene, only the character that is speaking will have normal modulated colors, while the characters who aren't speaking will grey out but not removed from the scene (I decided to use modulate to darken the portraits). Which part of the script should I look into? Or any better solution?

Hello, first thing, you marked this as a General discussion instead of a Question, if you can, you should fix that.

You can either use a script in your own game to handle the portraits or extend your own custom portraits.
Dialogic has the speaker_updated signal, it will inform you what character is speaking, then each portrait can automatically be adjusted.

Is this how should I connect it? Also I don't know how to access to "that character" in the signal, and change their modulate color when they are speaking / not speaking. I am kinda new to this...

Hey, this might be a bit late, but for anyone that comes across this like me, i have managed to solved it (not the best possible solution i am sure, i am still new at godot and dialogic).
What i did was selecting the 5Portraits layer in my style then making it custom, inside the scene that opens there are 5 portrait containers with a script, in this script i wrote
DialogicUtil.autoload().Text.speaker_updated.connect(_on_speaker_updated)
in the _ready func
and then created this func

func _on_speaker_updated(character:DialogicCharacter):
	if(get_child_count()>0):
		if(get_child(0).get_meta('character').display_name!=character.display_name):
			modulate = Color(0.1,0.1,0.1,1)
		else:
			modulate = Color(1,1,1,1)

Hope this helps!
