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:
Code: Select all
void OnAmxxAttach()
{
checkCompiler();
} Code: Select all
#include "amxxmodule.h"
#include "virtual_hook.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
//post
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
} Code: Select all
//register this virtual function
bool registerHook();
//remove this virtual function
bool removeHook();
/*got address this virtual function
you need to call, by using the VIRTUAL_CALL function*/
void *getAddress();
//got state this function (registered or no registered)
bool getState();Additional functions
Code: Select all
//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*/);
