BATTLE.BIN : - See if able to move to target?
Fill Table at 8019f3c4 + 0x3b4 : 1 byte per tile. For Each Tile, if tile is reachable : store distance between this Tile and Acting Unit Target Tile
------------------------------------------------------------------------------------------
Parameter : r4 = Acting Unit AI decision pointer ( 0x8019f3c4 + 0x182c)
Return : r2 = 0x00 if data are stored in Table at 8019f3c4 + 0x3b4
r2 = -0x01 if Find_Tiles_for_the_AI_to_move_to_(00178ca4) don't return 0x00
