Unity双击无法识别

Question

我一直在尝试将ios设备的双击统一化，但未能成功。 不幸的是，游戏无法识别双击。

我尝试了类似指针数据事件的不同方法，但是我也喜欢学习这种双击。

 
void Update () 
    {


        if (Input.touchCount > 0 && isGrounded== true)
         {
             for(int i =0; i < Input.touchCount; i++)
            {
             Touch touch = Input.GetTouch(i);
             timeTotal+=1;
             Debug.Log(timeTotal);


             if (touch.position.x < Screen.width/2 && (timeDelay < 0.5) && (timeTotal == 2))
             {
                 if(pathManager.randomDirection == 0)
                         {
                                 rb.AddForce(new Vector3(-4, 5, 4), ForceMode.Impulse);
                                 rb.velocity = Vector3.zero;
                                 timeTotal = 0;
                                 timeDelay =0;
                         }
