Code Crashes Client? C#

[strideynet]

Okay. So im brand new and super nooby. I did the usual cube FPS style. Then I added gui. Realizing the Gui couldn’t be interacted with i tried to add a new section to the normal look code.It would allow players to freeze camera movement. Now when I enter play mode it freezes unity!

using UnityEngine;
using System.Collections;

/// MouseLook rotates the transform based on the mouse delta.
/// Minimum and Maximum values can be used to constrain the possible rotation

/// To make an FPS style character:
/// - Create a capsule.
/// - Add a rigid body to the capsule
/// - Add the MouseLook script to the capsule.
/// -> Set the mouse look to use LookX. (You want to only turn character but not tilt it)
/// - Add FPSWalker script to the capsule

/// - Create a camera. Make the camera a child of the capsule. Reset it's transform.
/// - Add a MouseLook script to the camera.
/// -> Set the mouse look to use LookY. (You want the camera to tilt up and down like a head. The character already turns.)
[AddComponentMenu("Camera-Control/Mouse Look")]
public class look : MonoBehaviour {
	
	public enum RotationAxes { MouseXAndY = 0, MouseX = 1, MouseY = 2 }
	public RotationAxes axes = RotationAxes.MouseXAndY;
	public float sensitivityX = 15F;
	public float sensitivityY = 15F;
	
	public float minimumX = -360F;
	public float maximumX = 360F;
	
	public float minimumY = -60F;
	public float maximumY = 60F;
	
	float rotationX = 0F;
	float rotationY = 0F;
	
	Quaternion originalRotation;
	
	void Update ()
	{
					while (axes == RotationAxes.MouseXAndY && !Input.GetKeyDown("left shift")) 
					{
						// Read the mouse input axis
						rotationX += Input.GetAxis("Mouse X") * sensitivityX;
						rotationY += Input.GetAxis("Mouse Y") * sensitivityY;
						
						rotationX = ClampAngle (rotationX, minimumX, maximumX);
						rotationY = ClampAngle (rotationY, minimumY, maximumY);
						
						Quaternion xQuaternion = Quaternion.AngleAxis (rotationX, Vector3.up);
						Quaternion yQuaternion = Quaternion.AngleAxis (rotationY, -Vector3.right);
						
						transform.localRotation = originalRotation * xQuaternion * yQuaternion;
					}
					while (axes == RotationAxes.MouseX && !Input.GetKeyDown("left shift"))
					{
						rotationX += Input.GetAxis("Mouse X") * sensitivityX;
						rotationX = ClampAngle (rotationX, minimumX, maximumX);
						
						Quaternion xQuaternion = Quaternion.AngleAxis (rotationX, Vector3.up);
						transform.localRotation = originalRotation * xQuaternion;
					}
					while (axes == RotationAxes.MouseY && !Input.GetKeyDown("left shift"))
					{
						rotationY += Input.GetAxis("Mouse Y") * sensitivityY;
						rotationY = ClampAngle (rotationY, minimumY, maximumY);
						
						Quaternion yQuaternion = Quaternion.AngleAxis (-rotationY, Vector3.right);
						transform.localRotation = originalRotation * yQuaternion;
					}

			}
	
	void Start ()
	{
		// Make the rigid body not change rotation
		if (rigidbody)
			rigidbody.freezeRotation = true;
		originalRotation = transform.localRotation;
	}
	
	public static float ClampAngle (float angle, float min, float max)
	{
		if (angle < -360F)
			angle += 360F;
		if (angle > 360F)
			angle -= 360F;
		return Mathf.Clamp (angle, min, max);
	}
}

so. My pc is decent enough. I7 Intel core. 4GB DDR3. GTX 660. What have I broken?

Most Likely it is getting stuck in a while loop. try replacing the while loops with

if(axes == RotationAxes.MouseXAndY && !Input.GetKey("left shift"))

that should let execution continue.
