（二）简单触控

此部分简单触控是指在屏幕上简单的进行点击，拖动，鼠标（手指）按下与松开等功能，此部分unity  EventTrigger均可以实现，下边说一下Easy Touch实现

1）事件方法实现

    void Start () {
       EasyTouch.On_TouchStart += OnBeginTouch;
       EasyTouch.On_SwipeEnd += OnEndTouch;
       EasyTouch.On_Swipe += OnSwipe;
       EasyTouch.On_TouchDown += OnTouchDown;
    }

    private void OnDisable()
    {
        EasyTouch.On_TouchStart -= OnBeginTouch;
        EasyTouch.On_SwipeEnd -= OnEndTouch;
        EasyTouch.On_Swipe -= OnSwipe;
        EasyTouch.On_TouchDown -= OnTouchDown;
    }

   void OnDoubleTap()
    {
        Debug.Log("Double Tap");
    }

    void OnTouchDown(Gesture gesture)
    {
        Debug.Log("Touch Down");
    }

    void OnBeginTouch(Gesture gesture)
    {
        Debug.Log("Touch Begin:"+gesture.startPosition);
    }

    void OnEndTouch(Gesture gesture)
    {
        Debug.Log("End Touch:" + gesture.position);
    }

    void OnSwipe(Gesture gesture)
    {
        Debug.Log("Swipe:" + gesture.position);
    }

通过注册相关时间可以拖动，滑动滑动结束等诸多功能

2）通过当前Gesture实例进行实现

  void Update () {
        TouchEventControl();
    }

    void TouchEventControl()
    {
        Gesture currentGesture = EasyTouch.current;

        if (currentGesture == null) return;

        if(currentGesture.type==EasyTouch.EvtType.On_DoubleTap)
        {
            OnDoubleTap();
        }

        if (currentGesture.type == EasyTouch.EvtType.On_TouchDown)
        {
            OnTouchDown(currentGesture);
        }
    }
