unity实现鼠标拖拽物体的方法
作者:互联网
这三个方法都是没有优化过的方法,鼠标点到物体的时候物体的中心点会跳到鼠标点的位置,从一开始写的方法三理解之后慢慢删代码最后变成了方法一。。。。。。。。
public class 箭头 : MonoBehaviour
{
private bool 拖拽 = true;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
方法一::::::::::::::::::::::::::::::::::::::::::::::
Vector3 Mouseposition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
Mouseposition.z = 0;
float Distance = (this.gameObject.transform.position - Mouseposition).magnitude;
if (Input.GetMouseButton(0) && (Distance < 1.5f))
{
this.gameObject.transform.position = Mouseposition;
}
方法二::::::::::::::::::::::::::::::::::::::::::::::
Vector3 Mouseposition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
Mouseposition.z = 0;
if (Input.GetMouseButton(0))
{
float Distance = (this.gameObject.transform.position - Mouseposition).magnitude;
if (Distance < 1.5f)
{
this.gameObject.transform.position = Mouseposition;
}
}
方法三::::::::::::::::::::::::::::::::::::::::::::::
Vector3 Mouseposition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
Mouseposition.z = 0;
if (Input.GetMouseButton(0))
{
float Distance = (this.gameObject.transform.position - Mouseposition).magnitude;
if (Distance < 1.5f)
{
拖拽 = true;
}
}
else
{
拖拽 = false;
}
if (拖拽)
{
this.gameObject.transform.position = Mouseposition;
}
}
}
