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 [VisibleOnScreenEnabler2D] instead. [b]Note:[/b] VisibleOnScreenNotifier2D uses the render culling code to determine whether it's visible on screen, which also means that its [member CanvasItem.visible] must be [code]true[/code] to work correctly. </description> <tutorials> <link title="2D Dodge The Creeps Demo">https://godotengine.org/asset-library/asset/515</link> </tutorials> <methods> <method name="is_on_screen" qualifiers="const"> <return type="bool" /> <description> 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. </description> </method> </methods> <members> <member name="rect" type="Rect2" setter="set_rect" getter="get_rect" default="Rect2(-10, -10, 20, 20)"> The VisibleOnScreenNotifier2D's bounding rectangle. </member> </members> <signals> <signal name="screen_entered"> <description> Emitted when the VisibleOnScreenNotifier2D enters the screen. </description> </signal> <signal name="screen_exited"> <description> Emitted when the VisibleOnScreenNotifier2D exits the screen. </description> </signal> </signals> </class>
