简单的触摸控制

Question

我一直在我的电脑上测试我的游戏，使用左右箭头，但我想把它切换到触摸控制。

我查看了一些教程，但有人说我需要从商店购买资产，否则它并不真正符合我的需求。

我只需要一些关于我应该采取的最佳方向的指导:)

这是我现在的控件代码，我想知道是否可以使用 2 个按钮，因为我只需要左右移动？

 void Update()

 {

     transform.position = Vector2.MoveTowards(transform.position, targetPos, speed * Time.deltaTime);

     if (Input.GetKeyDown(KeyCode.RightArrow) && transform.position.x < maxWidth)

     {

         targetPos = new Vector2(transform.position.x + Xincrement, transform.position.y);

         transform.position = targetPos;

     }

     else if (Input.GetKeyDown(KeyCode.LeftArrow) && transform.position.x > minWidth)

     {

         targetPos = new Vector2(transform.position.x - Xincrement, transform.position.y);

         transform.position = targetPos;

     }

 }

使用点击时获取鼠标位置的代码，并检查它是在屏幕的右侧还是左侧
