p1end tile of drag
p2various bitstuffed elements
  • p2 = (bit 0) - start tile starts in the 2nd half of tile (p2 & 1). Only used if bit 6 is set or if we are building a single tile
  • p2 = (bit 1) - end tile starts in the 2nd half of tile (p2 & 2). Only used if bit 6 is set or if we are building a single tile
  • p2 = (bit 2) - direction: 0 = along x-axis, 1 = along y-axis (p2 & 4)
