BackBufferCopy

Inherits: Node2D < CanvasItem < Node < Object

Copia una región de la pantalla (o toda la pantalla) a un búfer para que se pueda acceder a ella en sus shader scripts a través de la función texture(SCREEN_TEXTURE, ...).

Descripción

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 set. Use the texture(SCREEN_TEXTURE, ...) function in your shader scripts to access the buffer.

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.
