Crust: A Configurable Minecraft Mod for Testing-Friendly Gameplay
If you enjoy experimenting with Minecraft mechanics, creating streamlined testing worlds, or running modded servers where admin tweaks matter, Crust brings a surprisingly practical toolkit to the table. It’s a code library and testing mod designed to make iteration easier, while still keeping everything configurable for both players and server operators. Instead of relying on constant command typing or repeated world setup, Crust adds hands-on controls directly where you already play: your inventory screen.
What Crust Adds to Your Minecraft Sessions
Crust focuses on two big areas: a testing toolkit and optional player modes. The mod is built around the idea that you should be able to adjust behavior without restarting everything, and without breaking your flow when you’re crafting, farming, or debugging gameplay.
The Inventory Button Testing Toolkit
The most recognizable feature is Crust’s set of customizable, keybindable “command-driven buttons” added to the inventory screen. Think of them as quick actions you can configure for whatever you’re testing at the moment.
- There are currently 19 built-in buttons to cover common testing needs.
- You can also create 16 user-defined buttons, choosing their look and assigning commands.
- All actions are designed to run quickly, so you can test mechanics without leaving the game.
Default Game Rules for New Worlds
As an added bonus, Crust lets you configure default game rules for newly created worlds. That means your test worlds can start with consistent rules, which is especially helpful when you’re comparing behavior across Minecraft versions or mod combinations.
Crust Modes: Extra Capabilities for Players
Crust modes are additional player capabilities, largely geared toward testing and controlled convenience. Importantly, each mode can have its own OP-level requirement, and server limitations can be applied. By default, only one mode is enabled for new players: Magnet, and it does not require “cheating ability.”
Available Crust Modes
- Magnet: Pulls nearby items toward you.
- Undying: Fully recover instead of dying.
- Unbreaking: Frequently fully repairs your items (but it does not prevent damage).
- Uneating: Restores food level when it drops below a threshold.
- Destroy-on-pickup: Manages inventory clutter by destroying items that attempt to invade your inventory.
- Super vision: Continuous night vision, disables water fog and blindness.
- Super speed: Increases sprint speed.
Commands You Can Use in-Game
Crust is designed to be operated through commands, particularly for inventory buttons and mode management. Here are the key command patterns you’ll run into:
- /crustclean pointer [player] — Destroy the item under the pointer.
- /crustmode [player] — Check which Crust modes are active for a player.
- /crustmode mode (disable|value) [players] — Enable or disable a Crust mode.
- /crustportal (portal_type) [target] — Create a dimension portal.
- /crustrecover [all|health|hunger|effects] [targets] — Restore health and/or hunger, and remove negative effects.
Config Management That Stays Simple
Instead of relying only on Forge’s standard configs, Crust provides its own configuration system. For modders, this means flexible implementation. For players and server operators, it means configs can be organized the way you prefer, and in many cases edited in-game through a GUI (not every field type is supported yet).
- Configs can be implemented in a modder-friendly way and presented cleanly for players.
- The system supports useful built-in field types, plus the option to add your own.
- You get practical tools for managing gameplay behavior rather than hand-tuning settings every session.
Extra Modding Utilities Beyond Modes
Crust also includes several utilities that can matter in bigger modded setups—especially when you’re building worlds with custom mechanics, managing data-driven behavior, or testing block interactions across different biomes.
- Advancement load event support.
- Tile entity bounding box rendering (intended for debugging, similar to F3+B behavior).
- A portal registry to support the /crustportal command.
- Data generation tools, including a loot table builder.
- Helpers for named setBlock flags, entity/level event codes, NBT handling, and miscellaneous math.
Installation and Server Setup Tips
For single-player testing or multiplayer servers, you’ll usually want Crust configured before you start iterating on gameplay. A convenient workflow is to install it using the foxygame.net launcher, which makes setup feel fast and modern—you can download mods right from the menu and get into your test worlds without extra fuss.
Once installed, focus on the modes you want enabled, then set the OP level rules so the right mechanics are available to the right players. That’s the key to keeping Crust helpful rather than chaotic, particularly on servers where you want predictable testing behavior across sessions.
Conclusion: Crust Makes Minecraft Testing Feel Effortless
Crust turns tedious iteration into quick, in-world control. With inventory button actions, configurable default game rules, and mode-based capabilities like Magnet, Undying, and Super speed, it’s built for players and server operators who want to test mechanics efficiently. Whether you’re debugging block behavior, crafting new server setups, or comparing outcomes across updates and versions, Crust gives you a clean toolkit that keeps your gameplay loop moving.
