Unity 鼠标点击跟随移动

代码内容

public class Mouse : MonoBehaviour

// Start is called before the first frame update
void Start()

}

// Update is called once per frame
void Update()

/// 跟随鼠标移动并旋转
/// </summary>

//2创建一个射线从相机位置到鼠标点击的位置的方向上
Ray ray = Camera.main.ScreenPointToRay(mouse);
//定义一个射线检测的保存对象
RaycastHit hit;//hit保存射线发射后碰撞的信息
//开始碰撞检测，射线检测返回一个bool类型，true:有碰撞,false:无碰撞
