Compiling DeActivate monsters in Avesta

[ond]

I wonder if someone could help me figure out how to deactivate monster in avesta when:

You are not on the same floor or in their targetList

if(targetList.empty()){
isActivated = false;
}

Something like this above

Also, the monsters should Not deactivate when player is invisible!

Thanks in advance

Change this:

bool Creature::canSee(const Position& myPos, const Position& pos, uint32_t viewRangeX, uint32_t viewRangeY)
{
	if(myPos.z <= 7){
		//we are on ground level or above (7 -> 0)
		//view is from 7 -> 0
		if(pos.z > 7){
			return false;
		}
	}
	else if(myPos.z >= 8){
		//we are underground (8 -> 15)
		//view is +/- 2 from the floor we stand on
		if(std::abs(myPos.z - pos.z) > 2){
			return false;
		}
	}

	int offsetz = myPos.z - pos.z;

	if ((pos.x >= myPos.x - viewRangeX + offsetz) && (pos.x <= myPos.x + viewRangeX + offsetz) &&
		(pos.y >= myPos.y - viewRangeY + offsetz) && (pos.y <= myPos.y + viewRangeY + offsetz))
		return true;

	return false;
}

To this:

    bool Creature::canSee(const Position& myPos, const Position& pos, uint32_t viewRangeX, uint32_t viewRangeY)
    {
            if(myPos.z <= 7){
                    //we are on ground level or above (7 -> 0)
                    //view is from 7 -> 0
                    if(pos.z > 7){
                            return false;
                    }
            }
            else if(myPos.z >= 8){
                    //we are underground (8 -> 15)
                    //view is +/- 2 from the floor we stand on
                    if(std::abs(myPos.z - pos.z) > 2){
                            return false;
                    }
            }
     
            if ((pos.x >= myPos.x - viewRangeX) && (pos.x <= myPos.x + viewRangeX) &&
                    (pos.y >= myPos.y - viewRangeY) && (pos.y <= myPos.y + viewRangeY) && pos.z == myPos.z)
                    return true;
     
            return false;
    }
