WebJun 16, 2015 · 1 Answer. It is bad practice to typedef your own unit32: Note that your version will not work, as long long is at least 64 bits). Instead use stdint.h as defined by the standard. There you will (very likely) find uint32_t, which is guaranteed to hold 32 bits. WebThe classical approach works ray-wise and uses pre-calculated ray-attacks for each of the eight ray-directions and each of the 64 squares. It has to distinguish between positive and negative directions, because it has to bitscan the ray-attack intersection with the occupancy in different orders. That usually don't cares for getting line- or ...
