The scene that is being animated.
Do not call this method directly; it is called by the system exactly once per frame, so long as the scene is presented in a view and is not paused. It is called after all update logic has been completed and before the scene is rendered.
Any additional actions applied are not evaluated until the next update.
Any changes to physics bodies are not simulated until the next update.
Any changes to constraints will not be applied until the next update.
No further update logic will be applied to the scene after this call. Any values set on nodes here will be used when the scene is rendered for the current frame.
