Interface Timepiece

All Known Implementing Classes:

DefaultTimepiece

public interface Timepiece

The Timepiece is the AI clock which gives you the current time and the last delta time i.e., the time span between the current frame and the last frame in seconds. This is the only service provider that does not depend on the environment, whether libgdx or not. It is needed because some parts of gdx-ai (like for instance MessageDispatcher, Jump steering behavior and Wait task) have a notion of spent time and we want to support game pause. It's developer's responsibility to update the timepiece on each game loop. When the game is paused you simply don't update the timepiece.
