С# недопустимый IL после изменения dll с помощью плагина Reflector и Reflexil

Я пытаюсь научиться взламывать игру, и я просто хотел начать с добавления некоторых функций. Я нашел вероятную функцию и хотел добавить немного кода перед основным выполнением, но игра сообщает о недопустимом IL при запуске. Хотя я не понимаю, что не так.

Исходный декомпилированный код был таким:

public void InitializeAfterInventory()
{
    if ((this.thisCharacterInstance.spawn_type == SpawnType.SpawnType_Avatar) && (this.inventory.curDeck != null))
    {
        ItemDef def = this.inventory.curDeck.def;
        base.baseAttributes.armor = def.decking_hardening;
        base.baseAttributes.body = def.decking_body;
        base.baseSkills.dodge = def.decking_evasion;
        base.baseAttributes.ap = def.decking_max_ap;
        base.baseAttributes.hp = def.decking_max_ip;
        base.SetHP(this.inventory.curDeck.CurrentHealth);
        base.SetAP(base.baseAttributes.ap);
        base.SetRP(StatsUtil.GetMaxArmor(this));
        this.inventory.InitializeAvatarItems(def.decking_default_weapon);
    }
    if ((this.thisCharacterInstance.spawn_type == SpawnType.SpawnType_Avatar) && (this.inventory.curDeck == null))
    {
        Logger.LogError(LogChannel.PLYR, base.name + " is of type avatar, but has no deck.  Stats unchanged");
    }
}

Я также добавил переменную типа «Item» с индексом 0 на вкладке «Variables» меню Reflexil для метода (чтобы присоединиться к другому типу ItemDef), это был единственный способ, чтобы он не вылетал сразу при попытке отобразить код. Я не понимаю, что не так, игра всегда показывает:

[...]
ERROR -1    *      PlayerInventory.EquipAvailableFromBackpack ()
ERROR -1 EXCEPTION: InvalidProgramException: Invalid IL code in Player:InitializeAfterInventory (): IL_0146: ret

Хм, может быть, peverify расскажет вам немного больше, чем просто InvalidProgramException?   -  person Erti-Chris Eelmaa    schedule 05.03.2015

Я нахожусь в Linux (используя это на вине, у которого нет хорошего способа установить peverify), но при использовании моно версии peverify обе библиотеки имеют похожие ошибки, которые я добавлю к вопросу   -  person i30817    schedule 05.03.2015

Мне нужен был поп после вызова первого статического метода (который возвращал объект). Я думал, что простое назначение его с помощью stloc будет всплывать, но нет, мне нужно было добавить всплывающее окно после назначения.
