Unity Android端操作-显示/影藏+旋转+放大缩小+截图的脚步代码

显示/影藏

 //获取操作对象
    public GameObject text;   
    //初始旋转角度
    public float xspeed = 120;
    void Start()
    {
      
    }

    // Update is called once per frame
    void Update()
    {
        MySetActive();
    }
    //手指点击关闭显示
    void MySetActive() 
    {
        //点击
        if (Input.GetMouseButton(0))
        {
            //一个手指点击
            if (Input.touchCount == 1 && Input.GetTouch(0).phase == TouchPhase.Began)
            {
                text.SetActive(false);
                //2个点击
                if (Input.GetTouch(0).tapCount == 2)
                {
                    text.SetActive(true);//显示
                }
            }
        }
    }
