|
The VisibilityNotifier2D detects when it is visible on the screen. It also notifies when its bounding rectangle enters or exits the screen or a viewport.
|
|
If you want nodes to be disabled automatically when they exit the screen, use [VisibilityEnabler2D] instead.
|
|
[b]Note:[/b] For performance reasons, VisibilityNotifier2D uses an approximate heuristic with precision determined by [member ProjectSettings.world/2d/cell_size]. If you need precise visibility checking, use another method such as adding an [Area2D] node as a child of a [Camera2D] node.

If [code]true[/code], the bounding rectangle is on the screen.
|
|
[b]Note:[/b] It takes one frame for the node's visibility to be assessed once added to the scene tree, so this method will return [code]false[/code] right after it is instantiated, even if it will be on screen in the draw pass.
