Description

A Viewport creates a different view into the screen, or a sub-view inside another viewport. Children 2D Nodes will display on it, and children Camera 3D nodes will render on it too.

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 Control, it will automatically take up its same rect and position, otherwise they 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.

Member Function Description

  • World find_world ( ) const

Return the 3D world of the viewport, or if no such present, the one of the parent viewport.

Return the 2D world of the viewport.

Return the active 3D camera.

Get the canvas transform of the viewport.

  • int get_clear_mode ( ) const
  • int get_debug_draw ( ) const

Get the total transform of the viewport.

Get the global canvas transform of the viewport.

  • bool get_hdr ( ) const

Get whether the rendered texture has filters enabled.

  • Vector2 get_mouse_position ( ) const

Get the mouse position, relative to the viewport.

  • int get_msaa ( ) const
  • bool get_physics_object_picking ( )

Get whether picking for all physics objects inside the viewport is enabled.

  • int get_render_info ( int info )
  • int get_shadow_atlas_quadrant_subdiv ( int quadrant ) const
  • int get_shadow_atlas_size ( ) const

Return the viewport rect. If the viewport is child of a control, it will use the same rect as the parent. Otherwise, if the rect is empty, the viewport will use all the allowed space.

  • Vector2 get_size_override ( ) const

Get the size override set with set_size_override.

Get the viewport’s texture, for use with various objects that you want to texture with the viewport.

  • int get_update_mode ( ) const

Get when the viewport would be updated, will be one of the UPDATE\_\* constants.

  • int get_usage ( ) const
  • bool get_vflip ( ) const

Set whether the render target is flipped on the Y axis.

  • RID get_viewport_rid ( ) const

Get the viewport RID from the VisualServer.

  • Rect2 get_visible_rect ( ) const

Return the final, visible rect in global screen coordinates.

  • World get_world ( ) const

Return the 3D world of the viewport.

  • Variant gui_get_drag_data ( ) const

Returs the drag data from the GUI, that was previously returned by Control.get_drag_data.

  • bool gui_has_modal_stack ( ) const

Returs whether there are shown modals on-screen.

  • bool has_transparent_background ( ) const

Return whether the viewport lets whatever is behind it to show.

  • bool is_3d_disabled ( ) const
  • bool is_audio_listener ( ) const

Returns whether the viewport sends sounds to the speakers.

  • bool is_audio_listener_2d ( ) const

Returns whether the viewport sends soundsfrom 2D emitters to the speakers.

  • bool is_input_disabled ( ) const

Return whether input to the viewport is disabled.

  • bool is_size_override_enabled ( ) const
