Uncrafting Blacklist
Twilight Forest's Uncrafting Table is a wonderfully chaotic block. It lets you reverse the crafting process, but sometimes it grants too much freedom, allowing players to exploit recipes or accidentally duplicate valuable resources. If you run a server or play a carefully balanced modpack, you know the pain of watching players turn a single diamond into a stack of unintended components. That is where Uncrafting Blacklist steps in, giving you precise, server-side control over what can and cannot be uncrafted.
This add-on, based on work originally by DoomRater, is a focused utility that slots directly into your existing setup. It does not change the core mechanics of the mod; it simply adds a powerful filter layer. You decide the rules, and the mod enforces them silently in the background. Whether you are playing on a private server with friends or managing a large public community, this tool is essential for maintaining fairness and preventing recipe-based exploits.
Core Features: Blacklisting Made Simple
The heart of Uncrafting Blacklist is its configuration file, which gives you two distinct types of blacklists. Understanding these is key to mastering the mod.
Item Input Blacklist
This list controls which items can be placed into the Uncrafting Table in the first place. If an item is on this list, players cannot even begin the uncrafting process with it. The configuration itemInputBlacklist supports several flexible formats:
modname:itemname– Blacklists a specific item from a specific mod.modname:itemname:metadata– Blacklists a specific variant, such as a specific wool color or log type.modname:itemname:*– A wildcard that blacklists all metadata values for that item.ore:oreDictionaryName– Blacklists an entire OreDictionary entry, catching all items that share that tag, like all ingots of a certain type.
Item Output Blacklist
This is the more nuanced filter. The itemOutputBlacklist checks the result of an uncrafting recipe. If the recipe would output an item on this list, then the input item is blacklisted entirely. For example, if you blacklist "minecraft:stick" as an output, then any item whose uncrafting recipe produces sticks (like a wooden shovel) becomes un-uncraftable. This is perfect for preventing players from generating infinite resources from a single crafted tool. The format for this list is identical to the input blacklist.
Server and Client Synchronization
One of the most critical aspects of any server-side restriction mod is ensuring that the client knows the rules. Uncrafting Blacklist handles this elegantly. The configuration is automatically synchronized between the server and the client. This means that when a player connects to your server, they immediately receive the blacklist data without any manual file copying.
The mod is smart about how it syncs this data. Instead of pushing the entire list upon login, which could cause lag on large servers, it synchronizes the information when a container (like the Uncrafting Table) is first opened. This reduces network overhead and keeps the game running smoothly. The synced data is temporary and is wiped whenever the player connects to a different server or enters single-player mode, ensuring no cross-server data leakage.
Commands and Administration
Managing your blacklist is straightforward. The primary command is /ubreload. This command, executed from the server console or by an operator, re-reads the configuration file and immediately synchronizes the updated information with all connected players. This is incredibly handy for making live adjustments without requiring a server restart or forcing players to reconnect. You can tweak a recipe, reload, and the change is instantly active for everyone.
Compatibility and Technical Notes
This mod is built for specific Minecraft versions and loaders, so be sure to check your modloader environment before downloading. It is designed to work seamlessly with Twilight Forest, and it uses code from Just Enough IDs to allow the use of Mixins with the code of other mods, ensuring broader compatibility with your existing modpack.
How to Install
Installing Uncrafting Blacklist is a standard process. First, ensure you have the correct version of Minecraft and the required mod loader (like Forge or NeoForge) installed. Then, download the mod jar file and place it into your mods folder. If you are playing on a server, the file must be present on both the server and the client. After launching the game once, the configuration file will be generated, which you can then edit to your liking.
For players who prefer a more streamlined approach to mod management, using a launcher with a built-in add-on catalog can simplify the process significantly. For instance, the foxygame.net launcher offers a curated catalog where you can find and install Uncrafting Blacklist with a single click, automatically handling version compatibility and dependencies, which saves you from the hassle of manual file management. The launcher's auto-update feature also ensures you are always running the latest build of Uncrafting Blacklist, keeping your server secure and bug-free.
Why You Need This Mod
Without a tool like this, the Uncrafting Table can be a source of severe balance issues. Consider a scenario where a player crafts a diamond pickaxe. Without a blacklist, they can uncraft it back into three diamonds. But what if they then use those diamonds to craft a different tool, uncraft it, and repeat? They can effectively duplicate resources or bypass the intended cost of certain items. Uncrafting Blacklist for Minecraft puts a stop to this by letting you define exactly which items are off-limits.
It is also an invaluable tool for custom modpack creators. If you have a specific progression path or a gated economy, this mod allows you to enforce those rules at a fundamental crafting level. It is lightweight, unobtrusive, and does exactly what it promises. The active development and community support via Patreon and Discord mean that bugs are fixed quickly and features are added based on user feedback.
In conclusion, if you value server integrity and balanced gameplay, this add-on is a must-have. It is a small investment in configuration time that pays off in preventing exploits and ensuring your world remains challenging and fair. Take the time to download Uncrafting Blacklist today and reclaim control over your crafting economy.
