Conditionally show exported variables

Question

Is it possible to have conditionally exported variables?
what I mean is something like this:

@export var is_moving_platform:bool = false
@exportif(is_moving_platform=true) var point1:Vectory3 = Vector3.ZERO
@exportif(is_moving_platform=true) var point2:Vectory3 = Vector3.ONE

So in the editor, the variables point1 and point2 would only appear if is_moving_platform is checked.

I believe this should be possible as I can see some of the settings for built-in types have something like that.
for example Area3D’s Gravity, you can check point to have some more options appear

There was an old thread asking the same, but the answer provided was related to Godot3, and not applicable to Godot4

Attention Topic was automatically imported from the old Question2Answer platform. Asked By Torajima I want to expose or hide variables based on choices in the editor. Something like this: export var moving = true if moving: export var speed = 200

I wrote a short tut on my wiki. Have a look.

If you need help after that, lemme know.

Seems more complicated than it should be.

I will give it a try, thanks for the quick answer.

totes agree.

OK after reading the wiki I can honestly say I do not fully comprehend it, however I was able to understand enough to make it work for what I wanted.

In case this is useful for others, this is what I did:

 # @tool is absolutely needed
@tool extends Node3D 

@export_category("Tile")
# This variable has to be exported
@export var is_moving_platform:bool = false:
	set(value):
		if value == is_moving_platform : return
		is_moving_platform = value
		notify_property_list_changed()
		
# These variables are going to be shown when is_moving_platform is checked.
var moving_speed:float = 5.0
var moving_points:Array[Node3D]

func _get_property_list():
	if Engine.is_editor_hint():
		var ret =[]
		if is_moving_platform:
			# This is how you add a normal variable, like String (TYPE_STRING), int (TYPE_INT)...etc
			ret.append({
			"name": &"moving_speed",
			"type": TYPE_FLOAT,
			"usage": PROPERTY_USAGE_DEFAULT,
			})
			# This is how you add an Array, to define a type it seems that "24/34:Class_Name" is needed in the hint_string, or you will end up with null
			ret.append({
			"name": &"moving_points",
			"type": TYPE_ARRAY,
			"hint": PROPERTY_HINT_TYPE_STRING,
			"hint_string": "24/34:Node3D",
			"usage": PROPERTY_USAGE_EDITOR | PROPERTY_USAGE_STORAGE | PROPERTY_USAGE_SCRIPT_VARIABLE
			})
		return ret

Thank you @dbat for the answer, you can feel free to close this Topic.
