2 = id from char
1525 = id from mob...

the function where it crashes:

Code:

---

void CGameServer::SendCharActionAttack(RwUInt32 uiSerialId, RwUInt32 uiTargetSerialId, CClientSession * pSession)
{

        RwBool bDamageApply = TRUE;

        printf("SendCharActionAttack SERIAL %i %i \n", uiSerialId,uiTargetSerialId);

        printf("AVATAR HANDLE TEST %i \n", pSession->GetavatarHandle());
        CNtlPacket packet(sizeof(sGU_CHAR_ACTION_ATTACK));
        sGU_CHAR_ACTION_ATTACK * res = (sGU_CHAR_ACTION_ATTACK *)packet.GetPacketData();

        res->wOpCode = GU_CHAR_ACTION_ATTACK;
        res->hSubject = uiSerialId;
        res->hTarget = uiTargetSerialId;
        res->bChainAttack = TRUE;

        res->wAttackResultValue = 150;
       
        res->byAttackSequence = rand()%2;

        if(res->byAttackSequence == 6)
        {
                if(rand()%2)
                        res->byAttackResult = BATTLE_ATTACK_RESULT_KNOCKDOWN;
                else
                        res->byAttackResult = BATTLE_ATTACK_RESULT_SLIDING;
        }
        else
        {
                RwInt32 iRandValue = rand()%5;
                if(iRandValue <= 2)
                        res->byAttackResult = BATTLE_ATTACK_RESULT_HIT;
                else if(iRandValue == 3)
                {
                        bDamageApply = FALSE;
                        res->byAttackResult = BATTLE_ATTACK_RESULT_DODGE;
                }
                else
                {
                        bDamageApply = FALSE;
                        res->byAttackResult = BATTLE_ATTACK_RESULT_BLOCK;
                }
        }

        packet.SetPacketLen( sizeof(sGU_CHAR_ACTION_ATTACK) );
        int rc = g_pApp->Send( pSession->GetHandle() , &packet );

}
