[Release] Reading monster_ref.bmo

[Plastic]

This is the structure for the monster_ref.bmo file. Everything marked with the comment "// not a monster attribute" means that it is ignored on the client. I believe it's only used on the server. You cannot change the text of "toolName" on the server monster_ref.bmo unless you modify the server executable, since it looks for "EOD Monster Ref" or it fails to load.

Psuedocode to read the file data in:

FILE* pFile = nullptr;

fopen_s( pFile, "monster_ref.bmo", "rb" );

if ( !pFile )
    exit();

MONSTERREF_HEADER monHeader;

fread( monHeader.toolName, 48, 1, pFile );
.... (fread rest of header );

// read type_id in
MONSTRUCTURE monStruct;
while ( true )
{
    fread( monStruct.type_id, sizeof( monStruct.type_id ), 1, pFile );

    if ( type_id == 65535 ) // 65535 == end of file
        break;

    MONSTERTABLE monTable = &monStruct.monTable;
    fread( monTable.level, sizeof( unsigned short ), 1, pFile );
    .... ( fread rest of file );
}

Saving the output should be straight forward with this info. I've also attached a 010 Editor 7.0 template that you can use to edit the file if you are unwilling or incapable of writing a program to handle it yourself.

Have fun
