Optionally, a viewport can have its own 2D or 3D world, so they don't share what they draw with other viewports. - If a viewport is a child of a [SubViewportContainer], it will automatically take up its size, otherwise it must be set manually. Viewports can also choose to be audio listeners, so they generate positional audio depending on a 2D or 3D camera child of it. Also, viewports can be assigned to different screens in case the devices have multiple screens. Finally, viewports can also behave as render targets, in which case they will not be visible unless the associated texture is used to draw. </description> <tutorials> - <link title="Using Viewports">https://docs.godotengine.org/en/latest/tutorials/rendering/viewports.html</link> - <link title="Viewport and canvas transforms">https://docs.godotengine.org/en/latest/tutorials/2d/2d_transforms.html</link> + <link title="Using Viewports">$DOCS_URL/tutorials/rendering/viewports.html</link> + <link title="Viewport and canvas transforms">$DOCS_URL/tutorials/2d/2d_transforms.html</link> <link title="GUI in 3D Demo">https://godotengine.org/asset-library/asset/127</link> <link title="3D in 2D Demo">https://godotengine.org/asset-library/asset/128</link> <link title="2D in 3D Demo">https://godotengine.org/asset-library/asset/129</link> @@ -25,13 +24,13 @@ <method name="find_world_2d" qualifiers="const"> <return type="World2D" /> <description> - Returns the 2D world of the viewport. + Returns the first valid [World2D] for this viewport, searching the [member world_2d] property of itself and any Viewport ancestor. </description> </method> <method name="find_world_3d" qualifiers="const"> <return type="World3D" /> <description> - Returns the 3D world of the viewport, or if none the world of the parent viewport. + Returns the first valid [World3D] for this viewport, searching the [member world_3d] property of itself and any Viewport ancestor. </description> </method> <method name="get_camera_2d" qualifiers="const"> @@ -55,7 +54,7 @@ <method name="get_mouse_position" qualifiers="const"> <return type="Vector2" /> <description> - Returns the mouse position relative to the viewport. + Returns the mouse's position in this [Viewport] using the coordinate system of this [Viewport]. </description> </method> <method name="get_render_info"> @@ -107,15 +106,28 @@ Returns the drag data from the GUI, that was previously returned by [method Control._get_drag_data]. </description> </method> + <method name="gui_get_focus_owner"> + <return type="Control" /> + <description> + Returns the [Control] having the focus within this viewport.
