el17tc 3:83e79d31930c 24 If it were up to me almost everything in this file would be in a Game object and main would only have game.init(); game.run(); in it
el17tc 3:83e79d31930c 25 Unfortunately I have been plagued by L6312W the empty execution region error (not the warning) all the way through this project
el17tc 3:83e79d31930c 26 and this is as good as I could get it in terms of object orientation.
el17tc 3:83e79d31930c 27 As far as I'm aware this error is a bug with the mbed compiler of this version but it can be worked around.
el17tc 3:83e79d31930c 28 Dock marks as you see fit for not encapsulating the other headers into a single class.
el17tc 3:83e79d31930c 29 (but the other classes are nice and object-oriented, right?)
