SubViewport
|
|
===========
|
|
|
|
**Inherits:** :ref:`Viewport<class_Viewport>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`
|
|
|
|
Creates a sub-view into the screen.
|
|
|
|
Description
|
|
-----------
|
|
|
|
``SubViewport`` is a :ref:`Viewport<class_Viewport>` that isn't a :ref:`Window<class_Window>`, i.e. it doesn't draw anything by itself. To display something, ``SubViewport``'s :ref:`size<class_SubViewport_property_size>` must be non-zero and it should be either put inside a :ref:`SubViewportContainer<class_SubViewportContainer>` or assigned to a :ref:`ViewportTexture<class_ViewportTexture>`.
