Knockback Problem

[mrscale 1]

i have noticed that when player attack another player there is no knockback

bool CHARACTER::Attack(LPCHARACTER pkVictim, BYTE bType)
{
	if (test_server)
		sys_log(0, "[TEST_SERVER] Attack : %s type %d, MobBattleType %d", GetName(), bType, !GetMobBattleType() ? 0 : GetMobAttackRange());

	//PROF_UNIT puAttack("Attack");
	if (!CanMove() || IsObserverMode())
		return false;

	// CASTLE
	if (IS_CASTLE_MAP(GetMapIndex()) && !castle_can_attack(this, pkVictim))
		return false;
	// CASTLE

	if (!battle_is_attackable(this, pkVictim))
		return false;

	DWORD dwCurrentTime = get_dword_time();

	if (IsPC())
	{
		if (IS_SPEED_HACK(this, pkVictim, dwCurrentTime))
			return false;

		if (bType == 0 && dwCurrentTime < GetSkipComboAttackByTime())
			return false;
	}
	else
	{
		MonsterChat(MONSTER_CHAT_ATTACK);
	}

#if defined(__TEMPLE_OCHAO__)
	if ((pkVictim->IsMonster()) && (pkVictim->GetMobTable().dwVnum == TempleOchao::GUARDIAN) && (pkVictim->GetMapIndex() == TempleOchao::MAP_INDEX))
		TempleOchao::CMgr::instance().AttackedGuardian(pkVictim);
#endif

	pkVictim->SetSyncOwner(this);

	if (pkVictim->CanBeginFight())
		pkVictim->BeginFight(this);

	int iRet;

	if (bType == 0)
	{
#if defined(__SOUL_SYSTEM__)
		if (IsAffectFlag(AFF_SOUL_RED) || IsAffectFlag(AFF_SOUL_MIX))
			UseSoulAttack(RED_SOUL);
#endif

		//
		// ÀÏ¹Ý °ø°Ý

		switch (GetMobBattleType())
		{
		case BATTLE_TYPE_MELEE:
		case BATTLE_TYPE_POWER:
		case BATTLE_TYPE_TANKER:
		case BATTLE_TYPE_SUPER_POWER:
		case BATTLE_TYPE_SUPER_TANKER:
			iRet = battle_melee_attack(this, pkVictim);
			break;

		case BATTLE_TYPE_RANGE:
			FlyTarget(pkVictim->GetVID(), pkVictim->GetX(), pkVictim->GetY(), HEADER_CG_FLY_TARGETING);
			iRet = Shoot(0) ? BATTLE_DAMAGE : BATTLE_NONE;
			break;

		case BATTLE_TYPE_MAGIC:
			FlyTarget(pkVictim->GetVID(), pkVictim->GetX(), pkVictim->GetY(), HEADER_CG_FLY_TARGETING);
			iRet = Shoot(1) ? BATTLE_DAMAGE : BATTLE_NONE;
			break;

		default:
			sys_err("Unhandled battle type %d", GetMobBattleType());
			iRet = BATTLE_NONE;
			break;
		}
	}
	else
	{
#if defined(__SOUL_SYSTEM__)
		if (IsAffectFlag(AFF_SOUL_BLUE) || IsAffectFlag(AFF_SOUL_MIX))
			UseSoulAttack(BLUE_SOUL);
#endif

		if (IsPC() == true)
		{
			if (dwCurrentTime - m_dwLastSkillTime > 1500)
			{
				sys_log(1, "HACK: Too long skill using term. Name(%s) PID(%u) delta(%u)",
					GetName(), GetPlayerID(), (dwCurrentTime - m_dwLastSkillTime));
				return false;
			}
		}

		sys_log(1, "Attack call ComputeSkill %d %s", bType, pkVictim ? pkVictim->GetName() : "");
		iRet = ComputeSkill(bType, pkVictim);
	}

	//if (test_server && IsPC())
		//sys_log(0, "%s Attack %s type %u ret %d", GetName(), pkVictim->GetName(), bType, iRet);

	if (iRet == BATTLE_DAMAGE || iRet == BATTLE_DEAD)
	{
		OnMove(true);
		pkVictim->OnMove();

		// Only pc sets victim null. For npc, state machine will reset this.
		if (BATTLE_DEAD == iRet && IsPC())
			SetVictim(NULL);

		return true;
	}

	return false;
}

i looked here but seems fine... any idea?
