in: src client/gamelib/ActorInstaceEvent.cpp Search:
virtual void OnHit
Replace all line with:
virtual void OnHit(UINT uMotAttack, CActorInstance& rkActorVictim, BOOL isSendPacket, bool fakedata) {}

in: src client/gamelib/ActorInstaceEvent.cpp Search:
CActorInstance::__OnHit
Replace the line like this:
rkEventHandler.OnHit(uSkill, rkActorVictm, isSendPacket, true);

in: src client/gamelib/ActorInstace.h Search:
virtual void OnHit(UINT uSkill, CActorInstance& rkActorVictim, BOOL isSendPacket) = 0;
Replace with:
