不错吧，，，

来代码

    string menuPage = "main";
	// Use this for initialization
	void Start () {

            new Rect(menuArea.x * Screen.width - (menuArea.width * 0.3f), menuArea.y * Screen.height - (menuArea.height * 0.3f), menuArea.width, menuArea.height);
       // menuAreaNormalized =
        //  new Rect(150, 70, Screen.width, Screen.height);
	}
