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]. https://godotengine.org/asset-library/asset/2712 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. Emitted when the VisibleOnScreenNotifier2D enters the screen. Emitted when the VisibleOnScreenNotifier2D exits the screen.
