Unity Crashes When Clicking Play: Script Error?

I have an issue, whenever I try to click play in the Unity Editor, the Editor freezes. This might be caused by a script error. According to this post

My Do/While script has a loop. Is there a way to fix it?
I am running Windows 10 x64 with Unity 5.3.5 (latest) version.

Here is the code that may have been causing the problem:

using UnityEngine;

public static class Helper
{
	public static float ClampAngle(float angle, float min, float max)
	{
		do 
		{
			if (angle < -360)
				angle += 360;
			if (angle > -360)
				angle -= 360;
		} while (angle < -360 || angle > 360);

		return Mathf.Clamp (angle, min, max); 

	}
}

This part is your problem:

if (angle > -360)
             angle -= 360;

I believe you want that to be if (angle > 360).

Currently your loop is just toggling the value back and forth between < -360 and > -360.

You can also eliminate the loop by using modulo arithmetic:

angle %= 360;
if (angle < 0) angle += 360;

That will always give you an angle between 0 and 360. I’ve not tested it fully so use at your own risk, but some flavor of that should work.
