我正在建立一个应用程序，用户点击一个按钮，一个音频源播放。有暂停和退出的选项。
我试着整合一个滑动条来显示进度。

{
    [Header("List of Tracks")]
    [SerializeField] private Track[] audioTracks;
    
    private int trackIndex; 
    
    [Header("Text UI")]
    [SerializeField] private TextMeshProUGUI trackTextUI;
    
    private AudioSource audio;
            
    // Start is called before the first frame update
    private void Start()
    {
        audio = GetComponent<AudioSource>();
        
        audio.clip = audioTracks[trackIndex].trackAudioClip;
        
        trackTextUI.text = audioTracks[trackIndex].name;
                
    }
    
    public void FiveMinuteMed()
    {
        trackIndex = 0;
        audio.Play();
    }
    
    public void TenMinuteMed()
    {
        trackIndex = 1;
        audio.Play();   
        
    }
    
    public void FifteenMinuteMed()
    {
        trackIndex = 2;
        audio.Play();
    }

  public void PlayAudio()
  {
      audio.Play();
  }
  
  public void PauseAudio()
  {
      audio.Pause();
  }
  
   public void StopAudio()
  {
      audio.Stop();
  }
  
 }

我试着把下面的代码段添加到on Update（）函数中..显然是在start上声明变量等。当我点击play..应用程序就冻结了..

public Slider time;
public AudioSource audio;
// Start is called before the first frame update
void Start()

    {
        audio = GetComponent<AudioSource>();
    }
    
    // Update is called once per frame
    void Update()
    {
        time.maxValue = audio.clip.length;
        time.value = audio.time;
        audio.time = time.value;
    }

有什么想法，我可以把滑块在原来的代码片段以上..？
