Unity延时执行的多种方法小结

 private float delayTime = 1;
    private float timer = 0;
    private bool executed = false;
    void Update(){
        if (executed == false){
            timer += Time.deltaTime;
            if (timer >= 1){
                executed = true;
                DelayFunc();
            }
        }
    }
    private void DelayFunc(){
        print("执行测试函数");
    }

 private float delayTime = 5;
    private void Start(){ 
        Invoke("DelayFunc",delayTime);
        //InvokeRepeating("DelayFunc",delayTime,cdTime);
    }
    private void DelayFunc(){
        print("执行测试函数");
    }

  private float timer = 0;
    private void Start()
    {
        StartCoroutine("DelayFunc");
        Time.timeScale = 0;
    }
    IEnumerator DelayFunc()
    {
        while ( timer < 30)
        {
            yield return new WaitForSeconds(1);
            timer++;
            print("执行测试函数"+timer); 
        }
    }

 private void Start()
    {
        seq = DOTween.Sequence();
        seq.AppendInterval(5);
        seq.AppendCallback(DelayFunc);
        seq.SetAutoKill(false);
        seq.SetUpdate(true);//设为true时可在Time.timeScale=0的情况下正常执行
        
    }
    void DelayFunc()
    {
        print("执行测试函数"); 
    }
