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 )
{
	if( Q_stricmp( var->GetString(), var->GetDefault() ) ) 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

Improved lagcompensation code

Open dlls/player_lagcompensation.cpp and replace, around line 369

// lost track, too much difference 
return;

with

// DM: Some small improvements for lagcompensation 
// From Plan of Attack-source 
// did we found a context smaller then target time ? 
if ( record->m_flSimulationTime <= flTargetTime ) 
 break; // hurra, stop  
// store this position for the next time through the loop 
prevOrg = record->m_vecOrigin; 
// go one step back 
curr = track->Next( curr ); 

Also take a look at the code from Sticky Player Collisions

• You don't see the muzzleflash/tracer of a func_tank gun.
• You don't see underwater bubbles
• When the player is on fire and dies, the fire doesn't disappear when he respawns
• Using shield-scanner in maps is not possible unless the mapname begins with d3
• Scriptsound NPC_CeilingTurret.ShotSounds doesn't exist
• Not all sk_ variables in the game_shared have the flag FCVAR_REPLICATED
• The sk_ damage variables for the crowbar and stunstick are removed in HL2DM
• Stunstick-sparks (random effect) are shown while the stunstick isn't the active weapon
• Ammo in the HUD doesn't reposition good after an resolution-change
• Many sounds of the physcannon are disabled in HL2DM

All fixed, so if you ask nice, I'll give you the fix.
Of course, there's a bigger list of missing features. For example: 'Get points when you kill an NPC' or a deathnotice with the name of the NPC that killed you.
