I’ve got it working, but I can’t manage to find the list of crafting literals (e.g. C for metal chest) to make a meaningful recipe.
And it still doesn’t work for sizes different from 54. I thought GUI would simply adjust to any other value. Well, that doesn’t bother me that much.
And what is ZL_IS? As in private ItemStack[] mInventory = ZL_IS;. This drives me crazy; is it OK in Java just to use identifiers out of nowhere not mentioning the class from where they’re imported
