public class CameraCollider : MonoBehaviour

public Camera cameragame;
// Start is called before the first frame update
void Start()

}
public float inputspeed=1f;//控制键速度
// Update is called once per frame
void Update()

float X = (Input.mousePosition.x - Screen.width / 2f)/(Screen.width/2);
float Y = (Input.mousePosition.y - Screen.height / 2f)/(Screen.height/2);

cameragame.transform.Rotate(Vector3.left*Y* inputspeed);//摄像机上下旋转

transform.Rotate(Vector3.up * X* inputspeed);//角色左右旋转
cameragame.transform.eulerAngles = new Vector3(cameragame.transform.eulerAngles.x,cameragame.transform.eulerAngles.y,0);//锁定自旋转
}

}
