Ошибка в ГС

[DeMi]

После удачной загрузки ГС и соединения с ЛС, в ГС постоянно выдает такую вот ошибку... Что за ошибка? С Чем связана и где искать устранение ее?

Перевел, что произошла ошибка при инициализации объекта Object ID = 268484402 java.lang.NullPointerException
в l2c.game.instancemanager.TownManager.getClosestTownName (TownManager.java: 54)

[LestatL]

в базе, в таблице итемы, удали данный итем и всё

[gorodetskiy]

откройте TownManager.java: 54 строку и посмотрите о чём идёт речь

выделите вашу сборку и нажмите shift+del, далее в гугл на поиск нормальной рабочей сборке без варнингов и косяков со спавном

[DeMi]

gorodetskiy, Я открыл строку 54: там вот такое:

Код:

    {
        return getClosestTown(activeChar).getName();
    }

А в AutoSpawnHandler.java вот такое, строка 429:

Код:

                String nearestTown = TownManager.getInstance().getClosestTownName(npcInst);

Как можно исправить данную ошибку? Буду благодарен очень!

LestatL, это разве решение проблемы? :/
А базе etcitem даже нет такого ID с таким итемом, там максимум до 1859 ID всего.
Есть еще таблица items, но там пусто...

/**
* Auto Spawn Handler
* Allows spawning of a NPC object based on a timer.
* (From the official idea used for the Merchant and Blacksmith of Mammon)
* General Usage:
* - Call registerSpawn() with the parameters listed below.
* int npcId
* int[][] spawnPoints or specify NULL to add points later.
* int initialDelay (If < 0 = default value)
* int respawnDelay (If < 0 = default value)
* int despawnDelay (If < 0 = default value or if = 0, function disabled)
* spawnPoints is a standard two-dimensional int array containing X,Y and Z coordinates.
* The default respawn/despawn delays are currently every hour (as for Mammon on official servers).
* - The resulting AutoSpawnInstance object represents the newly added spawn index.
* - The interal methods of this object can be used to adjust random spawning, for instance a call to setRandomSpawn(1, true); would set the spawn at index 1
* to be randomly rather than sequentially-based.
* - Also they can be used to specify the number of NPC instances to spawn
* using setSpawnCount(), and broadcast a message to all users using setBroadcast().
* Random Spawning = OFF by default
* Broadcasting = OFF by default

[LestatL]

LestatL, это разве решение проблемы? :/
А базе etcitem даже нет такого ID с таким итемом, там максимум до 1859 ID всего.
Есть еще таблица items, но там пусто...

а при чём тут etcitem ? - вам пишет конкретно, что итем (он мб и простой аденой) под таким то номером косячный, а все итемы находятся в таблице items - смотрите лучше и ядро тут не при делах!

[Zubastic]

Вообщем не может определить ближайший город. Попробуйте сделать ловушку: если null, то присваиваем что-то.

[DeMi]

LestatL, вот что в items...
Смотрел даже другие сборки сервером, аналогично, там пусто в items...




Zubastic, прошу прощения, а можно подробнее? Очень бы хотелось избавиться, решить эту проблему... Буду признателен Вам.

[Zubastic]

У вас objectid а не item.
