Как сделать границы камеры?

float speed = 6f;
public Transform target;
public Transform leftdown;
public Transform rightup;

private float xmin;
private float xmax;
private float ymin;
private float ymax;
private Vector3 position;
// Start is called before the first frame update
void Start()
{
Calk();
}

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


position = new Vector3(Mathf.Clamp(target.position.x, xmin, xmax),
Mathf.Clamp(target.position.y, ymin, ymax), transform.position.z);


print(xmin);


transform.position = Vector3.Lerp(transform.position, position, speed * Time.deltaTime);


}
private void Calk()
{
Vector3 min = Camera.main.ViewportToWorldPoint(new Vector3(0, 0, Camera.main.nearClipPlane)); //Получаем вектор нижнего левого угла камеры
Vector3 max = Camera.main.ViewportToWorldPoint(new Vector3(1f, 1f, Camera.main.nearClipPlane));

float x_left = leftdown.position.x;
float x_right = rightup.position.x;
float y_up = rightup.position.y;
float y_down = leftdown.position.y;

xmin = transform.position.x - (min.x - x_left);
xmax = (x_right - max.x) + transform.position.x;
ymin = transform.position.y - (min.y - y_down);
ymax = (y_up - max.y) + transform.position.x;

position = new Vector3(Mathf.Clamp(target.position.x, xmin, xmax),
Mathf.Clamp(target.position.y, ymin, ymax), transform.position.z);

}


Камера плавно следующая за персонажем, с границами по точкам.
В инспекторе персонажа ставь на target.
И две точки для границ камеры.
