Warning to CR developers about .IsFacing

[kaihaider]

The gameobject method .IsFacing only returns true if you are looking directly at it.

So unless you're aiming a sniper rifle, you'll probably want to use something like this:

        public static bool IsFacing(GameObject o)        {
            float headingTowardsTarget= MathEx.NormalizeRadian(MathHelper.CalculateHeading(Core.Me.Location, o.Location) + (float)Math.PI);
            float d = Math.Abs(MathEx.NormalizeRadian(Core.Me.Heading - headingTowardsTarget));
            if (d > Math.PI) d = Math.Abs(d - 2 * (float)Math.PI);
            //Logging.Write("Differance: " + d);
            return d < 0.785f;
        }
