MapHack is a system for Source SDK mods that allows the creation and manipulation of entities at runtime. Users can create alternative versions of maps, as well as patch them without the need to recompile the map.
Implemented into both No More Room in Hell and Pirates, Vikings, and Knights II.

Assuming you have a fresh installation of Source SDK2013:
- Copy
srcto either sp or mp directory (depending on your mod), so that both maphack_manager.cpp / .h files are in theserverdirectory - Add both files to your server VPC project, e.g.
server_hl2mp.vpc
$File "maphack_manager.cpp"
$File "maphack_manager.h"
- Open
game/server/cbase.cpp, then#include "maphack_manager.h", and on functionCBaseEntityOutput::FireOutput(), add this line of code at the bottom:
CMapHackManager::InvokeEntityOutputCallbacks( MapHackOutputCallbackParams_t( this, Value, pActivator, pCaller, fDelay ) );
0BSD, which means you can use this code in your mod without requirements.
