debugging - 如何阻止第二根手指在Unity3D中操纵gui操纵杆的位置

Question

我一直在 Unity3D 中开发 3D 移动应用程序，但最近遇到了一个问题。我有一个操纵杆可以让我的角色行走。操纵杆是一个 GUI 纹理。我设置了边界，因此您无法在屏幕上移动操纵杆。它的设置是这样的:当您的手指移出边界时，操纵杆会尽可能地移动，而当您向后移动手指时，操纵杆会继续与您​​的手指一起移动。这很好，但我将对其进行设置，以便沿着屏幕右侧移动另一根手指来旋转相机。当一根手指放在操纵杆上而另一根手指放在屏幕右侧时，就会出现此问题。当我沿着屏幕右侧移动一根手指时，操纵杆就会重置!这是我的代码...请帮忙!

好的，我修好了!我必须使用 touch.fingerId 而不是 Input.GetTouch(i).fingerId 花了一段时间，但现在它已经启动并运行了! :)
