Unity3D各种获取鼠标各种位置的小方法

Vector3 screenPosition; //将物体从世界坐标转换为屏幕坐标

 

Vector3 mousePositionOnScreen; //获取到点击屏幕的屏幕坐标

 

Vector3 mousePositionInWorld; //将点击屏幕的屏幕坐标转换为世界坐标

 

void Update()

 

{

 

MouseFollow();

 

}

 

void MouseFollow()

 

{

 

//获取鼠标在相机中（世界中）的位置，转换为屏幕坐标；

 

screenPosition = Camera.main.WorldToScreenPoint(transform.position);

 

//获取鼠标在场景中坐标

 

mousePositionOnScreen = Input.mousePosition;

 

//让场景中的Z=鼠标坐标的Z

 

mousePositionOnScreen.z = screenPosition.z;

 

//将相机中的坐标转化为世界坐标

 

mousePositionInWorld = Camera.main.ScreenToWorldPoint(mousePositionOnScreen);

 

//物体跟随鼠标移动

 

//transform.position = mousePositionInWorld;

 

//物体跟随鼠标X轴移动

 

transform.position = new Vector3(mousePositionInWorld.x,transform.position.y,transform.position.z);

 

}
