BATTLE.BIN : - Some height/Map coordinate calculation for all units Reset AI Table 0xb4c then enable Tile adjacent to an Ally with Monster Skill in AI 0xb4c Table (if delta Height is less than 2) Bug ? The last loop checking both elevation seems to not doing it. The way the counter is handled seems wrong to me. ------------------------------------------------------------------------------------------ Parameter : Nothing Return : Nothing ------------------------------------------------------------------------------------------ 0019cb94: 27bdffd8 addiu r29,r29,-0x0028 | 0019cb98: 00002021 addu r4,r0,r0 |Initialize Y counter 0019cb9c: afb10014 sw r17,0x0014(r29) | 0019cba0: 3c11801a lui r17,0x801a | 0019cba4: 2631f3c4 addiu r17,r17,-0x0c3c |8019f3c4 0019cba8: 02201821 addu r3,r17,r0 |Prepare Dynamic pointer to 0x8019f3c4 (1 halfword per iteration) 0019cbac: afbf0024 sw r31,0x0024(r29) | 0019cbb0: afb40020 sw r20,0x0020(r29) | 0019cbb4: afb3001c sw r19,0x001c(r29) | 0019cbb8: afb20018 sw r18,0x0018(r29) | 0019cbbc: afb00010 sw r16,0x0010(r29) | @LOOP -
