fuuro

The fuuro array indicates the fuuro tiles. The size of array is MJSCORE_INPUT_FUURO_NUM (20).

fuuro mapping

Array index	Description
0 + 4*n	The type of fuuro (0 = no fuuro, 1 = pon, 2 = chi, 3 = ankan, 4 = minkan, 5 = kakan)
1 + 4*n	The smallest tile number of its sets
2 + 4*n	The called tile number of its sets
3 + 4*n	The type of the other called house that relative to that person (1 = lower house, 2 = facing, 3 = upper house)

dora

The dora array indicates the dora tiles. The size of array is MJSCORE_INPUT_DORA_NUM (11).

dora mapping

Array index	Hand's type
0	The number of dora display tiles
1 to 5	1st to 5th dora display tile
6 to 10	1st to 5th "ura" dora display tile
