void OnItemAddedToContainer(ItemContainer container, Item item)
{
    Item obj = item;
    Item slot = obj.contents.GetSlot(0);
    var fuel = ItemManager.CreateByName("water", 5000);
    ItemModContainer component = obj.info.GetComponent<ItemModContainer>();
    if (slot == null && obj.name == "assets/prefabs/food/water jug/waterjug.entity.prefab")
    {
        fuel.MoveToContainer(obj.contents);
    }
}​

having trouble adding a check to my plugin, I've tried using if(item.name == "") with the short name, prefab name, and the in-game name but none of them work. how would I add a check to make sure the item is a waterjug?

solved it, for anyone else that has this issue, you can do if(item.info.itemid == -119235651)
