Question

I have created a “Road sign” scene that is:

node3d – attached script – “road sign”

    • MeshInstance3d – box mesh – “sign body”
        • Label3d #1 – “sign_label_front”
        • Label3d #2 – “sign_label_back”
    • MeshInstance3d – box mesh – “pole”

The script has an update_label() function (pasted below) that:

  • updates the text of the labels, and
  • resizes the box mesh based on the size of the label text.

This script is triggered by checking an “Update” box in the inspector.

This works.

But, when I reload my scene, the label text and boxmesh have reverted back to the road_sign scene’s default value.

Is there a way I can make these changes to the text labels and the sign body size permanent besides

  • Setting each road_sign in my scene as having editable children
    or
  • Running the update_label() function in each road_sign’s _onready()

?

If not, what are the downsides of making 20+ objects have editable children?

## Triggered by checking the "update" box in the inspector
func update_label():
	var Label_Front : Label3D =	$sign_body/sign_label_front
	Label_Front.text = sign_text.capitalize()
	$sign_body/sign_label_back.text = sign_text.capitalize()
	var sign_mesh : BoxMesh = $sign_body.mesh
	sign_mesh.size.x = Label_Front.get_aabb().size.x
