BackBufferCopy
==============

**Inherits:** :ref:`Node2D<class_Node2D>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

**Category:** Core

Brief Description
-----------------

Copies a region of the screen (or the whole screen) to a buffer so it can be accessed with ``SCREEN_TEXTURE`` in the ``texture()`` function.

Enumerations
------------

.. _enum_BackBufferCopy_CopyMode:

.. _class_BackBufferCopy_constant_COPY_MODE_DISABLED:

.. _class_BackBufferCopy_constant_COPY_MODE_RECT:

.. _class_BackBufferCopy_constant_COPY_MODE_VIEWPORT:

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 ``SCREEN_TEXTURE`` in the ``texture()`` function to access the buffer.
