How do I clamp the camera x rotation

Question

i have a rotate touch pad, that rotates a camera around a pivot how would I clamp the x rotation? basically how do i clamp the camera so it does not do backflips and frontflips

 #pragma strict
 
 @script RequireComponent(CharacterController)
 @script AddComponentMenu("Camera-Control/Smooth Look At")
 
 private var character : CharacterController;
 private var thisTransform : Transform;
 
 var rotateTouchPad : Joystick;
 var cameraPivot : Transform;
 
 var camRotation : Vector3 = Vector3(xCamRotation,yCamRotation,0);
 var xSpeed : float = .5;
 var ySpeed : float = .5;
 var xCamRotation : float = 0;
 var yCamRotation : float = 0;
 var rotationSpeed : Vector3 = Vector3(xSpeed,ySpeed,0);
 
 
 function Start () {
 
     character = GetComponent(CharacterController);
     thisTransform = GetComponent(Transform);
     
 
 }
     
 function LookFunction () {
 
     
     camRotation = rotateTouchPad.position;
     
     xCamRotation = rotateTouchPad.position.x;
     yCamRotation = rotateTouchPad.position.y;
     
     camRotation.x = xCamRotation;
     camRotation.y = yCamRotation;
     
     rotationSpeed.x = xSpeed;
     rotationSpeed.y = ySpeed;
     
     xCamRotation *= xSpeed;
     yCamRotation *= ySpeed;
     
     camRotation *= Time.smoothDeltaTime;
     
     cameraPivot.Rotate(0,xCamRotation,0,Space.World);
     cameraPivot.Rotate(-yCamRotation,0,0);
     
     //this line of code is not clamaping it
     cameraPivot.rotation.x = Mathf.Clamp(cameraPivot.rotation.x,-45,45);
     
     //this line of code is not clamping
     cameraPivot.eulerAngles.x = Mathf.Clamp(cameraPivot.eulerAngles.y,-45,45);
     
     
     
     
     
 }

Answer 1

if camera X rotation larger than 45, camera X rotation equals 45. If camera X rotation lower than -45, camera X rotation equals -45.

check out the last function here:

 var target : Transform;
 var distance = 10.0;
 
 var xSpeed = 250.0;
 var ySpeed = 120.0;
 
 var yMinLimit = -20;
 var yMaxLimit = 80;
 
 private var x = 0.0;
 private var y = 0.0;
 
 @script AddComponentMenu("Camera-Control/Mouse Orbit")
 
 function Start () {
     var angles = transform.eulerAngles;
     x = angles.y;
     y = angles.x;
 
     // Make the rigid body not change rotation
        if (rigidbody)
         rigidbody.freezeRotation = true;
 }
 
 function LateUpdate () {
     if (target) {
         x += Input.GetAxis("Mouse X") * xSpeed * 0.02;
         y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02;
          
          y = ClampAngle(y, yMinLimit, yMaxLimit);
                 
         var rotation = Quaternion.Euler(y, x, 0);
         var position = rotation * Vector3(0.0, 0.0, -distance) + target.position;
         
         transform.rotation = rotation;
         transform.position = position;
     }
 }
 
 static function ClampAngle (angle : float, min : float, max : float) {
     if (angle < -360)
         angle += 360;
     if (angle > 360)
         angle -= 360;
     return Mathf.Clamp (angle, min, max);
 }

check the last line in the ClampAngle function: Mathf.Clamp (....) That is what does the limit to rotation.
