Just trying to help narrow it down, looks like it refers to this block of code right ?

Code:
// Ok now, let's check pet's offhand.
                                        if (attack_dw_timer.Check() && GetOwnerID() && ( GetOwner()->GetClass() == MAGICIAN || GetOwner()->GetClass() == NECROMANCER || GetOwner()->GetClass() == SHADOWKNIGHT || GetOwner()->GetClass() == BEASTLORD ) )
                                        {
                                                if(GetOwner()->GetLevel() >= 24)
                                                {
                                                        float DualWieldProbability = (GetSkill(DUAL_WIELD) + GetLevel()) / 400.0f;
                            DualWieldProbability -= MakeRandomFloat(0, 1);
                                                        if(DualWieldProbability < 0){
                                Attack(target, 14);
                                if (CanThisClassDoubleAttack())
                                {
                                    sint32 RandRoll = rand()%100;
                                    if (RandRoll < (GetLevel() + 20))
                                    {
                                        Attack(target, 14);
                                    }
                                }
                                                        }
                                                }
                                        }
And something about the pets duel wield ? Well as far as pet classes that bit of code looks for he had MageX2, SKx2 and BLx1, Necx1

He does not give them weapons or gear.

Perhaps GetOwnerID() is returning a value but GetOwner() is returning NULL. That would cause the fault on the line being referenced in the error dump.

NULLS always seem to cause problem in code. A world without NULLS, imagine.

I am sure Congdar will look at it and go, "Oh yeah, the problem is this....". I am no damn help, I can barely read C++.

I went for my jog, stayed in ToV while I was gone. When I got back I was back to the log on screen, there was another dump and I ran it through. Looks like the same place.

provocating 06-13-2009 12:34 PM
