Unity某个物体始终朝向相机

 1.Unity某个物体始终朝向相机

        Quaternion q = Quaternion.identity;
        q.SetLookRotation(Camera.main.transform.forward, Camera.main.transform.up);
        goName.transform.rotation = q;

2.相机随鼠标转动，地平线还始终水平

    void Update()
    {
        float hor = Input.GetAxis("Mouse X") * Rotatespeed;
        float ver = Input.GetAxis("Mouse Y") * Rotatespeed;

        Vector3 forward = Quaternion.Euler(-ver, hor, 0) * Camera.main.transform.forward;
        Camera.main.transform.rotation = Quaternion.LookRotation(forward, Vector3.up);
    }
