Limiting X rotation

I need some help with a script I have right now its point and click but I want to limit how far up it can look or the X axis rotation. I do not want my guns to turn inwards towards the players ship when targeting something below or behind the spacecraft…

var turretRotationSpeed = 0.0;
var turret : Transform;
var shootAngleDistance = 0.0;

function Update ()
{

	
	
//Is the object mine on the network? if so then continue
    if(networkView.isMine)
	{
          var ray : Ray = Camera.main.ScreenPointToRay (Input.mousePosition);
          var hit : RaycastHit = new RaycastHit ();
          if (Physics.Raycast (ray, hit))
			{
			                //If the target is not there return or break till its not null
					if(hit == null)
						return;
				if(Physics.Raycast (ray, hit))
				{
					var targetPoint = hit.collider.gameObject.transform.position;
			
					var targetRotation = Quaternion.LookRotation ( targetPoint - turret.transform.position , Vector3.up);
					turret.transform.rotation = Quaternion.Slerp(turret.transform.rotation, targetRotation, Time.deltaTime * turretRotationSpeed);
				
				// If we are almost rotated towards target and player presses left mouse fire
				var forward = turret.transform.TransformDirection(Vector3.forward);
				var targetDir = hit.transform.position - turret.transform.position;
			 if (Input.GetMouseButton(0))
			{
				//If the turrents front "Z" is within a certain shooting angle and closest target 
				//tag is waypoint send message to firing script to "FIRE"
				if (Vector3.Angle(forward, targetDir) < shootAngleDistance)
				SendMessage("Fire");

			}
			}
			}
	}		
}

If you could edit your post and fix the code formatting, it would be easier to help. (For what it’s worth, I usually convert tabs to spaces before posting, which usually ensures that the formatting comes out right.)

Yeah I have issues with copy paste though is there a way to format the code like in visual studio? I would love that ahah

I would try converting tabs to spaces and then pasting.

do a “find and replace” of tabs, replace them with a few spaces each.
