/* battlesetup.h - laying out the ground a fight is fought on, and putting the * two sides down on it. * Ported from engine/ovr011.cs. * * This runs once, between the encounter being decided and the first round being * played. It has three jobs: * * the floor Thirteen dungeon squares by five are turned into the 50x25 * combat map: each square's four walls are looked up in the 3D * map and the six-by-five patch of isometric tiles that draws * them is written out. Out in the wilderness there is no wall * to look at, so the ground is scattered instead - trees, * bushes, rocks and a road - from the city the party is near. * * the combatants Each side is placed in rows spreading outwards from where it * stands, right of centre then left of centre, skipping squares * that are occupied or impassable. A side that will not fit * where it stands is walked round to a neighbouring square * first; an NPC there is no room at all for is turned loose. * * the round Everything a round needs cleared: the clouds, the fallen, the * round counter, and one Action per combatant. * * Almost all of it reads gbl rather than taking arguments, as the original did. * gbl.byte_1AD34 and gbl.byte_1AD35 say which dungeon square is being drawn and * gbl.dir_0_flags..dir_6_flags what stands around it; gbl.current_team, * gbl.team_start_x/y and gbl.team_direction say which side is being placed and * where from. * * Everything ovr011 calls is translated: engine/ovr006.cs's after-combat code is * aftercombat.c, and engine/ovr018.cs's FreeCurrentPlayer is in partymenu.c. */ #ifndef COAB_BATTLESETUP_H #define COAB_BATTLESETUP_H #include "coab.h" #include "player.h" /* ------------------------------------------------------------- the floor */ /* ovr011.set_background_tile, sub_37046.
