GBM

GBM, or the Glest Binary Map format, is the standard type of map. GBM is limited to 4 players, but can be used on any of Glest's engines, including MegaGlest and the Glest Advanced Engine. Maps in the GBM format are created in the Map Editor.

Structure

In GAE:

struct MapFileHeader{
   int32 version;
   int32 maxPlayers;
   int32 width;
   int32 height;
   int32 altFactor;
   int32 waterLevel;
   int8 title[128];
   int8 author[128];
   int8 description[256];
};

Or in MegaGlest, which supports cliffs:

struct MapFileHeader {
   int32 version;
   int32 maxPlayers;
   int32 width;
   int32 height;
   int32 altFactor;
   int32 waterLevel;
   int8 title[128];
   int8 author[128];
   union {
      int8 description[256];
      struct {
         int8 short_desc[128];
         int32 magic; // 0x01020304 for meta
         int8 meta[124];
      };
   };
};
