im trying to get the spell "utevo res" to allow me to walk through the creatures but only the master ofc.

i have tried several bools and just cant seem to get it to work

bool Player::canWalkthrough(const Creature* creature) const
{
    if (group->access || creature->isInGhostMode()) {
        return true;
    }

    const Player* player = creature->getPlayer();
    if (!player) {
        return false;
    }

    auto summons = player->getSummons();
    auto summonsIt = find(summons.begin(), summons.end(), creature);
    if (summonsIt != summons.end()) {
        return true;
    }

    const Tile* playerTile = player->getTile();
    if (!playerTile || !playerTile->hasFlag(TILESTATE_PROTECTIONZONE)) {
        return false;
    }

    const Item* playerTileGround = playerTile->getGround();
    if (!playerTileGround || !playerTileGround->hasWalkStack()) {
        return false;
    }

    Player* thisPlayer = const_cast<Player*>(this);
    if ((OTSYS_TIME() - lastWalkthroughAttempt) > 2000) {
        thisPlayer->setLastWalkthroughAttempt(OTSYS_TIME());
        return false;
    }

    if (creature->getPosition() != lastWalkthroughPosition) {
        thisPlayer->setLastWalkthroughPosition(creature->getPosition());
        return false;
    }

    thisPlayer->setLastWalkthroughPosition(creature->getPosition());
    return true;
}

bool Player::canWalkthroughEx(const Creature* creature) const
{
    if (group->access) {
        return true;
    }

    const Player* player = creature->getPlayer();
    if (!player) {
        return false;
    }

    const Tile* playerTile = player->getTile();
    return playerTile && playerTile->hasFlag(TILESTATE_PROTECTIONZONE);
}
