        if (Input.GetKeyDown(KeyCode.Space))
        {
            skin_Index++;

        if (GUI.Button(new Rect(0,0,Screen.width/10,Screen.height/10),"a button"))//创建按钮
        {
            Debug.Log("button has been pressed");//打印点击信息
        }
        GUI.Label(new Rect(Screen.height/10,Screen.width/10,Screen.height/5, Screen.width /5),"Hellow World");
        GUI.Box(new Rect(Screen.height / 5, Screen.width / 10, Screen.height / 5, Screen.width / 5), "a Box");
    }

}

 

将该脚本挂载到摄像机上后，为其gskin变量挂载两个或两个以上的GUISkin资源，运行 后可以通过敲击空格键切换预定的皮肤。
