No Parameters - Returns Nothing

Compare X and Y coordinates difference to determine which direction is the more relevant
If X = Y Facing is Front or Side (back only if Same coordinates (?))

If Attacked from side : Class Evade is nullified (0x801938e1)
If Attacked from back : Class Evade, Right and Left Hands Evade are nullified (0x801938e1, 0x801938df, 0x801938e0)
