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 texture(SCREEN_TEXTURE, ...) function.

Properties

CopyMode copy_mode 1
Rect2 rect Rect2( -100, -100, 200, 200 )

Enumerations

enum CopyMode:

  • 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.

Description

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.
