Custom Resource not emitting emit_changed on set(value)

Godot Version



I’m trying to register changes to a custom Resource, when the values are changed in the editor, but whatever I put in the set(value) function doesn’t seem to execute, whether it’s a print or emit:

class_name MyData
extends Resource

@export var width: int = 1:
        if value != width:
            width = value

I have a connection to the “changed” signal from a @tool Node, but it only seems to fire when the Resource script is updated.

Does anyone have any advice on how I can listen to changes to a Resource property value made through the inspector?


You probably need to set the Resource script to be a @tool script too.

Thanks, I gave that a go but no change unfortunately
