A rectangular region of 2D space that detects whether it is visible on screen.


VisibleOnScreenEnabler2D 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 screen_entered signal, and likewise it will emit a 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.

Note: VisibleOnScreenNotifier2D uses the render culling code to determine whether it's visible on screen, so it won't function unless CanvasItem.visible is set to true.





Rect2(-10, -10, 20, 20)



is_on_screen ( ) const


screen_entered ( )

Emitted when the VisibleOnScreenNotifier2D enters the screen.

screen_exited ( )

Emitted when the VisibleOnScreenNotifier2D exits the screen.

Property Descriptions

Rect2 rect = Rect2(-10, -10, 20, 20)

  • void set_rect ( Rect2 value )

  • Rect2 get_rect ( )

The VisibleOnScreenNotifier2D's bounding rectangle.

Method Descriptions

bool is_on_screen ( ) const

If true, the bounding rectangle is on the screen.

Note: It takes one frame for the VisibleOnScreenNotifier2D's visibility to be determined once added to the scene tree, so this method will always return false right after it is instantiated, before the draw pass.
