ATF_shadowedTowers2x2.c File Reference

Initializes the data structure which translates a list of struct ACD tiles into a list of shadowed towers. The overlap is a 2x2 grid of ACD tiles for each tower. More...

Variable Documentation

ATF_shadowedTowers ATF_ShadowedTowers2x2

Controls which tiles shadow which towers. This is a readonly data structure. It consists of 3 arrays indexed by tile number. The first array controls the top tiles and the other two array controls the X & Y side tiles. Symmetry allows one to use the X/Y maps for both the ends. The maps are packed in MSB order, ie tower 0 is the MSB bit. This is consistent with the FFS routine.
