You can call any functions you want. Just a matter to get a signature/symbol/header.

Arkshine,help me please.

can you give an example?

PHP Code:

#include "amxxmodule.h"
#include "chooker.h"

CHooker  HookerClass;
CHooker*    Hooker = &HookerClass;

typedef void ( *Func_RadiusDamage )( Vector, entvars_t, entvars_t, float, float, int, int  );
Func_RadiusDamage RadiusDamage_Addr = NULL;

bool hookRadiusDamage();
void RadiusDamage_Hook( Vector vecSrc, entvars_t *pevInflictor, entvars_t *pevAttacker, float flDamage, float flRadius, int iClassIgnore, int bitsDamageType );


void RadiusDamage_Hook( Vector vecSrc, entvars_t *pevInflictor, entvars_t *pevAttacker, float flDamage, float flRadius, int iClassIgnore, int bitsDamageType ) 
{
    GET_ORIG_FUNC( func );

    if( func->Restore() )
    {
        RadiusDamage_Addr( vecSrc, pevInflictor, pevAttacker, flDamage, flRadius, iClassIgnore, bitsDamageType );

        func->Patch();
    }

    printf( "\n\t\tHook RadiusDamage.\n" );
}

bool hookRadiusDamage()
{
    #ifdef _WIN32 
        RadiusDamage_Addr = Hooker->MemorySearch< Func_RadiusDamage>( "0xD9,*,*,*,0xD8,*,*,*,*,*,0x56,0x8B,0xF1,0x8B,0x4C,*,*,0xDF,*,0x25,*,*,*,*,0x8B", ( void* )gpGlobals, FALSE );
    #else
        RadiusDamage_Addr = Hooker->MemorySearch< Func_RadiusDamage>( "RadiusDamage__12CBaseMonsterP9entvars_sT1fii", ( void* )gpGlobals, TRUE );
    #endif

    return Hooker->CreateHook( ( void* )RadiusDamage_Addr, ( void* )RadiusDamage_Hook, TRUE ) ? true : false;
}

void OnMetaAttach()
{
    bool result = hookRadiusDamage();
    
    printf( " %s.\n\n", result ? "Loaded with success" : "Failed to create hook" );

}

You don't explain what is your problem.

1>..\meta_api.cpp(55): error C2664: void (Vector,entvars_t,entvars_t,float,float,int,i nt): can not convert parameter 3 from "entvars_t *" in "entvars_t"

        func->Patch();
    }

Seriously ?

Look at your header and your typedef and the error is really easy to understand.

[joropito]

The function type to be hooked should use the same prototype as the hook

typedef void ( *Func_RadiusDamage )( Vector, entvars_t*, entvars_t*, float, float, int, int  );

Why are posting right away instead of searching FIRST ?
Why do you never give details ?

Do you test windows/linux ? If windows, did you check if signature is right at least ?

[Bos93]

Solved

Not the correct signature
