BackBufferCopy #
is_instantiable, Node2D, Node, core, not_builtin_classes
A node that copies a region of the screen to a buffer for access in shader code.
Node for back-buffering the currently-displayed screen. The region defined in the BackBufferCopy node is buffered with the content of the screen it covers, or the entire screen according to the copy_mode. It can be accessed in shader scripts using the screen texture (i.e. a uniform sampler with hint_screen_texture).
Note: Since this node inherits from Node2D (and not Control), anchors and margins won't apply to child Control-derived nodes. This can be problematic when resizing the window. To avoid this, add Control-derived nodes as siblings to the BackBufferCopy node instead of adding them as children.
Members #
var copy_mode = COPY_MODE_RECT#
Buffer mode. See CopyMode constants.
var rect: Rect2 = Rect2(-100, -100, 200, 200)#
The area covered by the BackBufferCopy. Only used if copy_mode is COPY_MODE_RECT.
Methods #
Annotations #
Constants #
const COPY_MODE_DISABLED = 0 enum CopyMode#
Disables the buffering mode. This means the BackBufferCopy node will directly use the portion of screen it covers.
const COPY_MODE_RECT = 1 enum CopyMode#
BackBufferCopy buffers a rectangular region.
const COPY_MODE_VIEWPORT = 2 enum CopyMode#
BackBufferCopy buffers the entire screen.
