My script sets this value in editor. How can I keep the the changes when saving the scene?
class Anchor:
var offset: Vector3
var connected: Node3D
var end: bool
var anchors: Array[Anchor]
I found this issue, so I tried fiddling with _get_property_list(), but that didn’t work. It also doesn’t seem that I can export the var.
Thanks
You need to export them from your script.
Tried your code on a ready entity of my project, and indeed, @var anchors: Array[Anchor] can’t be exported if it’s in the same script.
What you could do, however, is initialize anchors as an empty array, var anchors = [] - This solves half of the problem, as you still won’t be able to add Anchor objects within the editor, because they “don’t exist”.
The likely solution in this case is making that Anchor class a standalone .gd file and add it to the Autoload list (Project Menu -> Project Settings -> Autoload tab). With this done, your original @export var anchors: Array[Anchor] will now work, because now that Godot autoloads it (makes it globally accessible), it “exists”
EDIT - Here’s the doc on _get_property_list https://docs.godotengine.org/en/stable/classes/class_object.html#class-object-method-get-property-list - From the example there, it added new things that don’t “exist” that should now show up on the editor. The thing is, it doesn’t specify if a locally created class would also work there.
#Might still be worth a shot, eh?
func _get_property_list():
var properties = []
properties.append({
"anchor_offset": Anchor.offset,
"anchor_connected": Anchor.connected,
"anchor_end": Anchor.end
})
return properties
Had to look up how to do that, as apparently the docs don’t have that kind of information. I did come across this SO question. So, the solution would be:
#anchor.gd
class_name Anchor
var offset: Vector3
var connected: Node3D
var end: bool
And that would create this new, readily accessible class throughout the project, correct?
