    //被改变的物体
    public GameObject Tab3;
    //需要改变的图片
    public Sprite Tab3Img;

    //加载将要用于修改的图片的路径
     public string TabImgPath2 = "Image/2";
    
    void Start()
    {

        //找到要被改变图片的物体
        Tab3 = GameObject.Find("Canvas/MainCanvas(Clone)/DaoHang/Tab1(3)");
        //加载图片
        Tab3Img = Resources.Load(TabImgPath2, typeof(Sprite)) as Sprite;
        //改变图片
        Tab3.GetComponent<Image>().sprite = Tab3Img;
