Node_Process Method

Called during the processing step of the main loop. Processing happens at every frame and as fast as possible, so the delta time since the previous frame is not constant. delta is in seconds.

It is only called if processing is enabled, which is done automatically if this method is overridden, and can be toggled with SetProcess(Boolean).

Corresponds to the notification in _Notification(Int32).

Note: This method is only called if the node is present in the scene tree (i.e. if it's not orphan).
