unity中在触控屏中Input.GetAxis("Mouse X")判断出现失误

我是靠谱客的博主自由期待，这篇文章主要介绍unity中在触控屏中Input.GetAxis("Mouse X")判断出现失误，现在分享给大家，希望可以做个参考。

在pc端中可以通过Input.GetAxis(“Mouse X”)或Input.GetAxis(“Mouse Y”)判断鼠标移动的方向，

但在触控屏中，以Input.GetAxis(“Mouse X”)或Input.GetAxis(“Mouse Y”)判断单点触控的手指滑动的方向容易发生错误，故不建议在触控屏中使用此方法。

以下是在触控屏的单点触控或pc鼠标滑动控制物体旋转：

复制代码

using UnityEngine;
public class ContralObject : MonoBehaviour {
public GameObject MainBuilding; //主建筑模型
private bool isPressLeft = false;//是否刚刚开始旋转
private Vector2 newPosition;
private Vector2 oldPosition;
void Update()
{
//控制物体旋转
if (Input.GetMouseButton(0))//鼠标左键
{
if (isPressLeft == false)
{
oldPosition = Input.mousePosition;
isPressLeft = true;
return;
}
else
{
newPosition = Input.mousePosition;
}
if (Mathf.Abs(newPosition.x - oldPosition.x) > Mathf.Abs(newPosition.y - oldPosition.y) && Mathf.Abs(newPosition.x - oldPosition.x) > 0.5f)
{
MainBuilding.transform.Rotate(Vector3.down * (newPosition.x - oldPosition.x) * Time.deltaTime * 5, Space.World);//绕Y轴进行旋转
}
/*
//控制x轴，即上下角度旋转
if (Mathf.Abs(newPosition.x - oldPosition.x) < Mathf.Abs(newPosition.y - oldPosition.y) && Mathf.Abs(newPosition.y - oldPosition.y) > 0.5f)
{
Vector3 add = MainBuilding.gameObject.transform.localEulerAngles + Vector3.right * (newPosition.y - oldPosition.y) * 0.1f;
float xx = add.x;
if (xx >= 66 && xx < 180)
{
xx = 66;
}
if (xx < 0)
{
xx = 0;
}
MainBuilding.gameObject.transform.localEulerAngles = new Vector3(xx, MainBuilding.gameObject.transform.localEulerAngles.y, MainBuilding.gameObject.transform.localEulerAngles.z);
}*/
oldPosition = newPosition;
}
if (Input.GetMouseButtonUp(0))
{
isPressLeft = false;
}
}
}
