How to make it so that when rotated, the object does not climb over the texture?

Question

Unity

Part of the script that rotates the object:

float AngleRotate = RotateSpeed ​​* Input.GetAxis("MoveTower");
rot.z = Mathf.Clamp( rot.z + AngleRotate, -yLimit, yLimit);
Tower.transform.eulerAngles = rot;
I made this code the gun is placed vertically, I can’t understand why and how can I fix it?

Answer 1

float AngleRotate = Time.deltaTime * RotateSpeed * Input.GetAxis("MoveTower");
AngleRotate = Mathf.Clamp(AngleRotate, MIN, MAX);
Tower.transform.Rotate(0, 0, AngleRotate);
