Tutorial *73*

A really short tutorial this one, a quick hack to stop the fatal error that occurs when you try to change the level to an incorrect version BSP. In gl_model.c, change



if (i != BSPVERSION)

	Sys_Error ("Mod_LoadBrushModel: %s has wrong version number (%i should be %i)", mod->name, i, BSPVERSION);

to:



if (i != BSPVERSION)

{

	Con_Printf("Mod_LoadBrushModel: %s has wrong version number (%i should be %i)", mod->name, i, BSPVERSION);

	mod->numvertexes=-1;	// HACK - incorrect BSP version is no longer fatal

	return;

}

Now in sv_main.c, underneath:



if (!sv.worldmodel)

{

	Con_Printf ("Couldn't spawn server %s\n", sv.modelname);

	sv.active = false;

	return;

}

add:



if (sv.worldmodel->numvertexes == -1)

{

	Con_Printf ("Couldn't spawn server %s\n", sv.modelname);

	sv.active = false;

	return;

}

Compile the code. Now put a Quake2 BSP file (or any other, as long as it isnt a Quake1 BSP) into your id1\maps folder, and try load it. If everythings gone right, you should get dropped back to the console instead of Quake crashing with an error.
