C++ Skills Damage

[kLaw]

hey guys ..

This is a part of sirix old OTP la code .

I want to make it a modification for skill ShieldOffensive from commander because its really sux and comma's need some action .

static void (__thiscall* Real_LifeAsorbtion) (void* pSkill, void* pPlayer, char* pPacket, char* pPos) = (void (__thiscall*) (void*, void*, char*, char*))0x00488330;
-> 0x00488330 -> this is the life absorption addr
--> Tried to find the shieldoffensive one but no chance . anyone can give me a hand in this?

static unsigned (__thiscall* AverageDamage) (void* pPlayer) = (unsigned (__thiscall*) (void*))0x0043D970;
-> this addr is for calculating your average damage

static bool (__thiscall* CheckHit) (void* pPlayer, void* pTarget, int arg) = (bool (__thiscall*) (void*, void*, int))0x43DA00;
-> this is for checking if you miss target or you hit it .

static char* (__cdecl* ReadPacket)(char *pPacket, char *pPos, const char *sFormat, ...) = (char* (__cdecl*)(char*, char*, const char*, ...))0x4975F0;
-> this is for reading packets like "db","dbbd" etc . i dont know what they are really means but maybe someone can explain this to us

static void* (__cdecl* FindMonster) (int nID) = (void* (__cdecl*) (int))0x0043A240;

static void* (__cdecl* FindPlayer) (int nID) = (void* (__cdecl*) (int))0x00450810;

static void (__cdecl* WriteInSight) (void* pPlayer, BYTE bType, const char *Format, ...) = ( void (__cdecl*) (void*, BYTE, const char*, ...))0x0040B9E0;

static LONG (__thiscall* ObjectRelease)(void* pOject, LONG lpAddend) = (LONG (__thiscall*)(void*, LONG))0x4239C0;

Guys . Who is experienced in this.. maybe you can help us . im not the only one who's asking for this but. all i really want is to make some changes for old kals . wanna start and old school soon :P so would be nice from you if you help me .

Give me tips ! thank you . Greetz

This should be ShieldOffense if i am not totally wrong ( 0x00481750 ) ^^

thank you for your reply . i'll check now :P

now ill have to figure out how i'll use it :P anyway thanks for your fast reply
