Copies a region of the screen (or the whole screen) to a buffer so it can be accessed in your shader scripts through the
texture(SCREEN_TEXTURE, ...) function.
Node for back-buffering the currently-displayed screen. The region defined in the BackBufferCopy node is bufferized 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.
- COPY_MODE_DISABLED = 0 — Disables the buffering mode. This means the BackBufferCopy node will directly use the portion of screen it covers.
- COPY_MODE_RECT = 1 — BackBufferCopy buffers a rectangular region.
- COPY_MODE_VIEWPORT = 2 — BackBufferCopy buffers the entire screen.
- CopyMode copy_mode
Buffer mode. See CopyMode constants.
- Rect2 rect
