<?xml version="1.0" encoding="UTF-8" ?> <class name="BackBufferCopy" inherits="Node2D" version="3.11"> <brief_description> Copies a region of the screen (or the whole screen) to a buffer so it can be accessed in your shader scripts through the [code]texture(SCREEN_TEXTURE, ...)[/code] function. </brief_description> <description> 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 [code]texture(SCREEN_TEXTURE, ...)[/code] function in your shader scripts to access the buffer. [b]Note:[/b] 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 [i]siblings[/i] to the [BackBufferCopy] node instead of adding them as children. </description> <tutorials> </tutorials> <methods> </methods> <members> <member name="copy_mode" type="int" setter="set_copy_mode" getter="get_copy_mode" enum="BackBufferCopy.CopyMode" default="1"> Buffer mode.
