Virtual Hook System
1
Virtual Hook System by Juli
This is ready system to hook virtual functions, which will allow catch any virtual event in the gaming world. There is support for the new and old builds (you don't need to bother about offsets and their differences in the old and new builds, it was all done instead of you).
Installation
The first step is to call the check build function (at all, check compiler, but let will be so). For this, catch
OnMetaAttach also
OnAmxxAttach function, in which we call the necessary function:
PHP Code:
void OnAmxxAttach () checkCompiler ();
Example of use
PHP Code:
#include "amxxmodule.h" VIRTUAL_CALLBACK ( void ) PlayerTakeDamage ( void * pthis VIRTUAL_ARG , entvars_t * pInflictor , entvars_t * pAttacker , float fDamage , int iDamagebits ); virtualHook pTakeDamage ( "player" , virtualHookName :: takedamage , ( void *) PlayerTakeDamage ); void OnAmxxAttach () checkCompiler (); void ServerActivate ( edict_s * a , int b , int c ) pTakeDamage . registerHook (); void ServerDeactivate () pTakeDamage . removeHook (); VIRTUAL_CALLBACK ( void ) PlayerTakeDamage ( void * pthis VIRTUAL_ARG , entvars_t * pInflictor , entvars_t * pAttacker , float fDamage , int iDamagebits ) //pre VIRTUAL_CALL < void >( pTakeDamage . getAddress (), pthis , pInflictor , pAttacker , fDamage , iDamagebits ); //call original function in gamedll edict_t * pVictim = UTIL_PrivateToEdict ( pthis ); //get this edict const char * szName = STRING ( pVictim -> v . netname ); //get this player name CENTER_SAY ( PLID , "Player %s received damage" , szName ); //say to all in center }
Available functions of the class
PHP Code:
//register this virtual function bool registerHook (); //remove this virtual function bool removeHook (); /*got address this virtual function void * getAddress (); //got state this function (registered or no registered) bool getState ();
Additional functions
PHP Code:
//got offset necessary function inline int getVirtualOffset ( int hookid ); //mentioned in paragraph "Installation" inline void checkCompiler ( void ); //for call the original function at address template < typename ReturnType > inline ReturnType VIRTUAL_CALL ( void * address , /*arguments required function*/ ); inline edict_t * UTIL_PrivateToEdict ( void * pvPrivateData ); inline edict_t * UTIL_EntvarsToEdict ( entvars_t * pthis ); inline int UTIL_EdictToIndex ( edict_t * pthis ); inline int UTIL_EntvarToIndex ( entvars_t * pthis ); inline int UTIL_PrivateToIndex ( void * pthis );
P.S. : The arguments necessary virtual functions can be seen in the comments to
virtualHookName enum:
