Okay, so, I have my coding for my treasure chests, and I can get anything I want into it, but I can't figure out enchanted books. I can add books with enchants on them, but I can't get Enchanted Books (that you can put into an anvil and put the enchantment on your item) into them.

 

TileEntityChest chest20 = (TileEntityChest) world.getTileEntity(i + 46, j + 19, k + 13);
        if (chest20 == null) {
            System.err.printf("TileEntityChest20 is null!?!\n");
        }
        else {
            for (int slot = 0; slot < chest20.getSizeInventory(); slot++) {
                int slotran = random1.nextInt(30);
                int itemran = random2.nextInt(3);
                if (slotran == 20){
                    ItemStack stack = new ItemStack(Items.enchanted_book);
                    stack.addEnchantment(Enchantment.featherFalling, itemran+1); //this just adds a book with an enchant, not an enchanted book.
                    chest21.setInventorySlotContents(slot, stack);
                }
                if (slotran == 25){
                   ItemStack stack = new ItemStack(Items.enchanted_book, 1, 0);
                    WeightedRandomChestContent tmp = new WeightedRandomChestContent(stack, 1, 1, 1); //This adds an "Enchanted Book" that has no enchants.
                    chest21.setInventorySlotContents(slot, stack);
                }
            }
        }

Are you giving example code to help others, or are you having an error? What is the actual problem if there is one?

-facehoof- ugh...it only posted half of my post...sorry about that. I edited it.

You should use

Items.enchanted_book.addEnchantment(stack, enchantment)

instead of

stack.addEnchantment(enchantment)
