Making the antlion burn!

Add the following under protected in npc_antlion.h

virtual	bool		AllowedToIgnite( void ) { return true; }

Well, now the damh thing burns but it doesn't visually respond to it. You can use the drown-animation: Add the following piece of code to the top of the function GatherConditions():

if( IsOnFire() )
{
	SetCondition( COND_ANTLION_IN_WATER );
}

UTIL_LoadTexture

Here's a very handy function from the Plan Of Attack source.

int UTIL_LoadTexture(const char *szFile)
{
#ifdef CLIENT_DLL
	char szStr[256];

	// try to pull it
	int iID = vgui::surface()->DrawGetTextureId(szFile);

	// did we get it?
	if(iID >= 0)
		return iID;

	// does the file exist?
	Q_snprintf(szStr, sizeof(szStr), "materials/%s.vmt", szFile);
	if(!vgui::filesystem()->FileExists(szStr))
	{
		DevMsg("UTIL_LoadTexture: texture %s does not exist!\n", szFile);
		return -1;
	}

	// create the new texture
	iID = vgui::surface()->CreateNewTextureID();
	vgui::surface()->DrawSetTextureFile(iID, szFile, true, false);

	return iID;
#else
	return -1;
#endif
}

Disallow players connecting to a server with a different version

Add the file version.h to your game_shared and add it to both projects. Content:

#define VERSION "0.01"

Then add to cdll_client_int.cpp:

void cl_versionCallback_f( ConVar *var, char const *pOldString )
{
	var->Revert();
}
static ConVar	cl_version	( "cl_version", VERSION, FCVAR_USERINFO|FCVAR_CLIENTDLL, "The version of this mod",
				cl_versionCallback_f );

Then open GameInterface.cpp and find the function ClientConnect() Replace the contents of that function with this:

	// DM: Get the version of the client and compare it with the server's version
	const char* version = engine->GetClientConVarValue( engine->IndexOfEdict( pEdict ), "cl_version" );

	if (stricmp(VERSION, version) == 0)
	{
		return g_pGameRules->ClientConnected( pEdict, pszName, pszAddress, reject, maxrejectlen );
		// Aka true
	}
	else
	{
		char string [256];
		Q_snprintf( string, sizeof(string), "The server runs a different version (%s)", VERSION);
		Q_strcpy( reject, string ); 
		maxrejectlen = strlen(string);
		return false;
	}

Just don't forget to change the define everytime you release a new version

Bugs found while making a co-op mod

• You hear the warning-sound when you spawn without any weapons & ammo.
• Fallen items/weapons from NPCs respawn.
• APC doesn't aim good
• Metropolice with stunstick doesn't work
• Citizens with RPG don't work
• You don't hear footsteps of NPCs.
• Crash/'players not dropping objects' when hit hard and have something picked with the gravity gun.
• Sceneentity doesn't find !player.
• effects/strider_muzzle not cached when you spawn an combine with the AR2.
• Deaths are not counted at the scoreboard when killed by an NPC.
• filter_damage_type-entity doesn't work
• Commanding citizens doesn't work.
• Hoppers don't work
• You don't see tracers & muzzleflash when a NPC shoots

Of course, there's a bigger list of missing features. For example: 'Get points when you kill an NPC'
