    private float mSmoothingSpeed = 1f;

    private float mWaitTime = 2;//计时器
    public override void StateStart()//寻找image
    {
        mLogo = GameObject.Find("Logo").GetComponent<Image>();
        mLogo.color = Color.black;
        
    }

    public override void StateUpdate()
    {
        mLogo.color = Color.Lerp(mLogo.color, Color.white, mSmoothingSpeed * Time.deltaTime);
        mWaitTime = Time.deltaTime;
        if(mWaitTime <= 0)
        {
            mController.SetState(new MainMenuState(mController));//切换到主菜单
        }
    }
}

在开始场景得时候图片无限从黑到白然后反复循环，StartScene都不能加载完。
