c# - 轻按几下如何修复？

Question

我有一个角色轮换，就是基于这个。有一个操纵杆。如果您先将手指放在角色的旋转上，然后再放在操纵杆上 - 一切都很好。但是，如果一开始在操纵杆上，然后尝试转动，什么都不会发生!帮助。几天不能决定

 void Start()
    {
        mContr = GameObject.FindGameObjectWithTag("Joystick").GetComponent<MobileController>();
    }

            deadStatus = false;
            ch_animator.SetBool("dead", false);
        }
        if(xp <= 0)
        {   if(deadStatus == false)

问题来自while循环:

您的逻辑仅适用于旋转玩家的 k=0 和快乐的 k=1，并且您开始以 k=1 的值进入 while 循环，如果该值是旋转玩家的位置，则测试是否始终为假

if(Input.GetTouch(k).position.x > Screen.width / 2 - 100)

我建议你像这样重构你的代码:

当您有 2 次触摸 k=0 和 k=1 时，请为每次触摸找到正确的操作。

我不明白你为什么不进入 k=0 的 while 循环？
