Property Descriptions

Setter set_aabb(value)
Getter get_aabb()

The VisibilityNotifier’s bounding box.

Method Descriptions

  • bool is_on_screen ( ) const

If true, the bounding box is on the screen.

Note: It takes one frame for the node’s visibility to be assessed once added to the scene tree, so this method will return false right after it is instantiated, even if it will be on screen in the draw pass.
