Detects approximately when the node is visible on screen.
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.
