A rectangular region of 2D space that detects whether it is visible on screen.
[VisibleOnScreenNotifier2D] represents a rectangular region of 2D space. When any part of this region becomes visible on screen or in a viewport, it will emit a [signal screen_entered] signal, and likewise it will emit a [signal screen_exited] signal when no part of it remains visible. If you want a node to be enabled automatically when this region is visible on screen, use [VisibleOnScreenEnabler2D]. [b]Note:[/b] [VisibleOnScreenNotifier2D] uses the render culling code to determine whether it's visible on screen, so it won't function unless [member CanvasItem.visible] is set to [code]true[/code].

If [code]true[/code], the bounding rectangle is on the screen. [b]Note:[/b] It takes one frame for the [VisibleOnScreenNotifier2D]'s visibility to be determined once added to the scene tree, so this method will always return [code]false[/code] right after it is instantiated, before the draw pass.
- The VisibleOnScreenNotifier2D's bounding rectangle.
- If [code]true[/code], shows the rectangle area of [member rect] in the editor with a translucent magenta fill. Unlike changing the visibility of the VisibleOnScreenNotifier2D, this does not affect the screen culling detection.
Emitted when the VisibleOnScreenNotifier2D enters the screen.
Emitted when the VisibleOnScreenNotifier2D exits the screen.
