| WolfMap global definitions | (c) Oct 1992 Sysma Automatisering |
---------------------------------------------------------------------------
| Version 1.0 06/10/92 | First implementation. |
| | J.P. Dijkstra, M.Sc. |
| Version 1.01 07/10/92 | Added automatic renaming of the game |
| | maps file during format conversions. |
| | J.P. Dijkstra, M.Sc. |
| Version 1.05 11/10/92 | Removed all explicit references to far |
| | pointers and changed the memory model to |
| | large. |
| | J.P. Dijkstra, M.Sc. |
| Version 1.5 12/10/92 | Added functions which enable copying and |
| | storing modified GameMaps inside a |
| | MapGlobalRec instance. |
| | J.P. Dijkstra, M.Sc. |
| Version 1.6 20/10/92 | Removed the list of map headers from the |
| | map data, since it was only used by one |
| | command and saves about 2K of memory. |
| | J.P. Dijkstra, M.Sc. |
---------------------------------------------------------------------------
| This header file contains definitions shared among the various source |
| files used to create WolfMap.Exe |

| | visible on the display. |
| ChoiseLegend | Determines from which legend the selected |
| | choise is on the display. |
| ShowFloors | Holds whether or not the floor values |
| | should be made visible. |

| | should be made visible. |
| SizeX | Holds the horizontal size of the map |
| | currently in the editor. |
| SizeY | Holds the vertical size of the map |
| | currently in the editor. |
| StartTextY | Holds a calculated internal value. Used |
| | to speedup certain draw actions. |
---------------------------------------------------------------------------
| GameMapRec | Class holding all data of one single map. |
| ErrorCode | Holds the last error code. |
| CurrentFormat | Holds the code representing the current |
| | compression format of the data blocks. |
| Maze | Data block holding the maze data. |
| Objects | Data block holding the objects data. |
| Unknown | Data block holding data for a presently |
| | unknown function. |
| Header | Data block holding the map header. |
| ActorCount | Holds the number of actors of each actor |
| | type, except special actors. |
| HugeActorCount | Holds the number of special actors. |
