Exporting Node variable can't trigger setget in tool mode.

Godot version

4.0 beta 6

System information

This is system-independent.

Issue description

As title.

This is because when the exported node variable a_variable is modified, the editor actually modifies the variable metadata/_ editor_prop_ptr_a_variable, so the setget defined in the @ tool script does not work.

Steps to reproduce

@tool
extends Node

@export var a_export_node: Node :
    set(v):
         print("set!")
         a_export_node = v

Minimal reproduction project

very easy to reproduce.

This is still an issue with setget in tool mode. Tested with the following code:

@tool
extends Node2D

@export var foo: bool:
	set(value):
		print("foo setter invoked")
		foo = value

In-Editor toggle boolean: Set foo
Run Scene: foo setter invoked

@export var foo: bool:

		foo = value

In-Editor toggle boolean: Set foo Run Scene: foo setter invoked

Maybe it is another issue? This issue is focusing on exporting variable that is Node type. And the problem is in editor metadata. Your code can work in previous version, at least the time when I report this.

I just double checked, the issue was in not reloading the scene to get the most current script behaviour. Closing the scene and reopening resolved the problem. :face_palm:

Does not work. Exported nodes remain nulls in the editor as of 4.0.2.

To clarify, OP's bug is still happening in v4.0.3.stable.official. Setting primitive type values in the editor does trigger the setter, but setting Node type values doesn't. I still see Set metadata/_editor_prop_ptr_value in the Output. NodePath does work as a workaround though

• I'm unable to reproduce in v4.1.rc1.mono.official [1f9e540].
• It seems this was fixed by Fix typed array export #76389.
• Also, this issue seems to be a duplicate of Exported Nodes are Nil in @tool mode #74141.
