Tfs 1.2
I found this on combat.cpp

Inside function

void MagicField::onStepInField(Creature* creature)

const ItemType& it = items[getID()];
    if (it.conditionDamage) {
        Condition* conditionCopy = it.conditionDamage->clone();
        uint32_t ownerId = getOwner();
        if (ownerId) {
            bool harmfulField = true;

            if (g_game.getWorldType() == WORLD_TYPE_NO_PVP || getTile()->hasFlag(TILESTATE_NOPVPZONE)) {
                Creature* owner = g_game.getCreatureByID(ownerId);
                if (owner) {
                    if (owner->getPlayer() || (owner->isSummon() && owner->getMaster()->getPlayer())) {
                        harmfulField = false;
                    }
                }
            }

            Player* targetPlayer = creature->getPlayer();
            if (targetPlayer) {
                Player* attackerPlayer = g_game.getPlayerByID(ownerId);
                if (attackerPlayer) {
                    if (Combat::isProtected(attackerPlayer, targetPlayer)) {
                        harmfulField = false;
                    }
                }
            }

            if (!harmfulField || (OTSYS_TIME() - createTime <= 5000) || creature->hasBeenAttacked(ownerId)) {
                conditionCopy->setParam(CONDITION_PARAM_OWNER, ownerId);
            }
        }

        creature->addCondition(conditionCopy);
    }
}

Someone can tell me how harmfulField work?

 

[oen432]

Checks if creature that steps on it is:

• the one that made that field
• one of the summons of a creature that made that field
• player is attacking another player (in PvP mode or such)

If false, field can do damage.

 

[gubbo123]

In this part for example,

            if (!harmfulField || (OTSYS_TIME() - createTime <= 5000) || creature->hasBeenAttacked(ownerId)) {
                conditionCopy->setParam(CONDITION_PARAM_OWNER, ownerId);

If the field damage is more than 5 seconds, no have morr owner yes?

For example, how can i put replace this
createTime <= 5000 to all day? Is possible without put there number 999999?

If the field damage is more than 5 seconds

This actually made my day.

You can actually remove that statement so the ownership won't be based on time at all

if (!harmfulField || creature->hasBeenAttacked(ownerId)) {
    conditionCopy->setParam(CONDITION_PARAM_OWNER, ownerId);
