Question

I’m creating a custom signal, and its argument is a Texture2D:

public partial class Node3d : Node3D
{
	Texture2D sprite;

    [Signal] public delegate void eventIdleEventHandler(Texture2D texture);

    void SetTexture(Texture2D _spr)
	{
		sprite = _spr;
    }
}

In the editor I can assign functions to be called when this signal is invoked, and I also have the option to Add Extra Call Argument (if the Advanced option is toggled).

My issue is that I can’t add an argument that is of type Texture2D from the UI. However I can add an array argument, add one value and make that value a Object that in turn can be interpreted as a Texture2D.

So I’m wondering whether this is a bug in the editor, or if there is a workaround for this.

Bottom image: Current setup with an array of one Object interpreted as a Texture2D

(Note: The example is fictional, and the scripting language should be irrelevant in this context)

There is no need for a workaround since you can add an object as a signal parameter.
(Unless I am misunderstanding your concern)

signal test(v:Object)

func _moo(v:Object)->void: 
	print(v)

func _ready() -> void:
	test.connect(_moo)
	test.emit(self)

Edit:
I think I understand now that you are asking how to do this for built in signals.
Have a look at the answers here
And the documentation (method bind):

Thanks for your reply. My original post was unclear, and has now been updated.
