Using Grid with - coordinates

[timhc22]

More of a discussion than an issue, but I have created a game with a 'grid' which is based on x and y coordinates, where 0,0 is the center, and so the character can move into -1 x and -1 y. Does using this library only work with grids which start at 0,0 and have positive coordinates?

No it should work both ways. I just tested it out myself and it worked just fine.
