    private int frame;              // 通過幀數
    private float time = 0;         // 運行時間

    private void Update () {
        frame += 1;
        time += Time.deltaTime;

        // 刷新幀率
        if (time >= sampleTime) {
            float fps = frame / time;
            text.text = "FPS:" + fps.ToString("F2");
            frame = 0;
            time = 0;
        }
    }
