unity中實現三個Logo圖片進行3秒鍾的若隱若現后互相切換Logo圖片

    private List<Sprite> storeTexture;
    public void Start()
    {
        storeTexture = new List<Sprite>();

        Sprite texture3 = Resources.Load<Sprite>("Textures/3");
        storeTexture.Add(texture3);
        //遍歷List中物體並打印出名字
        foreach (var kk in storeTexture)
        {
            Debug.LogError(kk.name);
        }
    }

unity中使用Image組件更換Logo圖片屬性如下：
1、sprite     用來渲染圖像的精靈。

2、overrideSprite　　設置用於呈現的覆蓋精靈，設置為null將恢復默認的srpite。

unity中使用RawImage組件更換圖片屬性是  texture  （RawImage的紋理）
