<?xml version="1.0" encoding="UTF-8" ?> <class name="VisibilityNotifier2D" inherits="Node2D" version="4.0"> <brief_description> Detects approximately when the node is visible on screen. </brief_description> <description> 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. </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"> </return> <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 VisibilityNotifier2D's bounding rectangle. </member> </members> <signals> <signal name="screen_entered"> <description> Emitted when the VisibilityNotifier2D enters the screen. </description> </signal> <signal name="screen_exited"> <description> Emitted when the VisibilityNotifier2D exits the screen. </description> </signal> <signal name="viewport_entered"> <argument index="0" name="viewport" type="Viewport"> </argument> <description> Emitted when the VisibilityNotifier2D enters a [Viewport]'s view. </description> </signal> <signal name="viewport_exited"> <argument index="0" name="viewport" type="Viewport"> </argument> <description> Emitted when the VisibilityNotifier2D exits a [Viewport]'s view. </description> </signal> </signals> <constants> </constants> </class>
