Quick start guide

• Turn on physics interpolation: Project Settings > Physics > Common > Physics Interpolation
• Make sure you move objects and run your game logic in _physics_process() rather than _process(). This includes moving objects directly and indirectly (by e.g. moving a parent, or using another mechanism to automatically move nodes).
• Be sure to call Node.reset_physics_interpolation on nodes after you first position or teleport them, to prevent "streaking".
• Temporarily try setting Project Settings > Physics > Common > Physics Tick per Second to 10 to see the difference with and without interpolation.
