Description

Node for back-buffering the currently-displayed screen. The region defined in theBackBufferCopy node is buffered with the content of the screen it covers, or the entire screen according to thecopy_mode. It can be accessed in shader scripts using the screen texture (i.e. a uniform sampler withhint_screen_texture).

Note: Since this node inherits fromNode2D (and notControl), anchors and margins won't apply to childControl-derived nodes. This can be problematic when resizing the window. To avoid this, addControl-derived nodes assiblings to theBackBufferCopy node instead of adding them as children.

Enumerations

enumCopyMode:🔗

CopyModeCOPY_MODE_DISABLED =0

Disables the buffering mode. This means theBackBufferCopy node will directly use the portion of screen it covers.

CopyModeCOPY_MODE_RECT =1

BackBufferCopy buffers a rectangular region.

CopyModeCOPY_MODE_VIEWPORT =2

BackBufferCopy buffers the entire screen.
