Add NOTIFICATION_PROCESS_MODE_ENABLED / DISABLED

[TAGames]

Everytime you want to run logic when a node becomes "enabled/disabled" you have to manually create a function inside that nodes script and call it from somewhere else.

There is no notification when process_mode or physics_process_mode changes to disabled/inherited.
There are NOTIFICATION_ENABLED and NOTIFICATION_DISABLED but those are used when collision objects collisions get enabled/disabled.

And there are no engine callbacks like:
_on_enable()
_on_disable()
_on_process_mode_enabled()
etc.

What can I do?
Will node stashing solve this issue by having a callback for _stashed() and _unstashed()?

Are you sure? They are called from Node::set_process_mode():

Thanks, somewhere I read that it is for Area3D etc. I will test it. :)

@passivestar:
Thank you so much! It is like you said. Should have tested it before creating a new thread. Thought my source was correct about this.

My Test:

@tool
extends Node

func _notification(what: int) -> void:
	if what == NOTIFICATION_DISABLED:
		print("disabled")
	if what == NOTIFICATION_ENABLED:
		print("enabled")
