public class LoadGame : MonoBehaviour {

    public Slider processView;

    }
	
	void Update () {
		
    }
    public void LoadGameMethod()
    {
        StartCoroutine(StartLoading_4(2));
    }

    private IEnumerator StartLoading_4(int scene)
    {
        int displayProgress = 0;//当前进度
        int toProgress = 0;//目标进度
        AsyncOperation op = SceneManager.LoadSceneAsync(scene); 
        op.allowSceneActivation = false;
        while (op.progress < 0.9f)
        {
            toProgress = (int)op.progress * 100;
            while (displayProgress < toProgress)
            {
                ++displayProgress;
                SetLoadingPercentage(displayProgress);
                yield return new WaitForEndOfFrame();   //等待这一帧所有渲染完成，才进行接下来的操作（+1 视图渲染完成）
            }
        }

        toProgress = 100;
        while (displayProgress < toProgress)

        }
        op.allowSceneActivation = true;
    }

    private void SetLoadingPercentage(float v)
    {
        processView.value = v / 100;
    }
}
