//注册事件
```

}

private void App()

 /*Some objects were not cleaned up when closing the scene. (Did you spawn new GameObjects from OnDestroy?)The following scene GameObjects were found:Singleton of InputEvent*///出现这种原因一般是我们在OnDestroy里边访问了这个单例。结束运行的时候这个单例实例已经变成了“null”。你在调用它的时候又产生了一个新的实例才会报这个错误。TODO:请去修改单例脚本/* InputEvent.Instance.onLeftTriggerEnter -= Test;InputEvent.Instance.onLeftAppButtonEnter -= App;InputEvent.Instance.onRightTriggerEnter -= Test;InputEvent.Instance.onRightAppButtonEnter -= App;
