It also notifies when its bounding rectangle enters or exits the screen or a [Camera3D]'s view. If you want nodes to be disabled automatically when they exit the screen, use [VisibleOnScreenEnabler3D] instead. [b]Note:[/b] VisibleOnScreenNotifier3D uses the render culling code to determine whether it's visible on screen, which also means that its [member Node3D.visible] must be [code]true[/code] to work correctly. </description> <tutorials> </tutorials> <methods> <method name="is_on_screen" qualifiers="const"> <return type="bool" /> <description> If [code]true[/code], the bounding box 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="aabb" type="AABB" setter="set_aabb" getter="get_aabb" default="AABB(-1, -1, -1, 2, 2, 2)"> The VisibleOnScreenNotifier3D's bounding box. </member> </members> <signals> <signal name="screen_entered"> <description> Emitted when the VisibleOnScreenNotifier3D enters the screen. </description> </signal> <signal name="screen_exited"> <description> Emitted when the VisibleOnScreenNotifier3D exits the screen. </description> </signal> </signals> </class>
