我在Android应用程序中使用AndEngine和Box2d.
如何使我的对象"播放器"抛出一个事件并且"GameScene"订阅它？

public class Player {

  @Override
  public void Collision(GameObject object) {
    if(object instanceof Coin) {
        //throws an event here
    }
  }
}

public class GameScene {
  private Player player = new Player();
  //catch the event here

}
