Byte angles follow this system:
A byte angle is from 0 to 255, where 0 means east, 64 north, 128 west and 192 south.
:0 0 degrees (East)
:64 =  90 degrees (North)
:128 = 180 degrees (West)
:192 = 270 degrees (South)
To convert from degrees to byte angles, use the following calculation:
byteangle = (degrees * 256) / 360
Chop or round the result to an integer.
Valid byte angles fall between 0 and 255, so adjust any angles less than 0 or greater than or equal to 360 before performing this conversion.
