Inherits: Node2D < CanvasItem < Node < Object
Copies a region of the screen (or the whole screen) to a buffer so it can be accessed in your shader scripts using the screen texture (i.e. a uniform sampler with
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 screen texture 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.
CopyMode COPY_MODE_DISABLED =
Disables the buffering mode. This means the BackBufferCopy node will directly use the portion of screen it covers.
CopyMode COPY_MODE_RECT =
BackBufferCopy buffers a rectangular region.
CopyMode COPY_MODE_VIEWPORT =
BackBufferCopy buffers the entire screen.
CopyMode copy_mode =
Buffer mode. See CopyMode constants.
Rect2 rect =
Rect2(-100, -100, 200, 200)
The area covered by the BackBufferCopy. Only used if copy_mode is COPY_MODE_RECT.
