Can't access map_array: TypeError: 'int' object is not subscriptable

[pahp]

I tried to add in the map_array[][] using the code that worked for Space Invaders, but when I touch map_array in bot code, I get the following errors:

The bot code in question was

foo = map_array[0][0]

I have punted this issue for now -- I just removed map_array from the code (commented it out) and removed it from the documentation. The game should be playable without the map.
