VanillaConfig Mod FAQ

VanillaConfig saves configuration files to your game's config folder (usually `.minecraft/config/`), organized by mod ID. Look for a file named after the mod you're configuring—it will be in a human-readable format like JSON or TOML depending on the mod's setup.

Yes, VanillaConfig stores configs in plain text formats that you can edit manually. After saving your changes, restart the game or reload the config through the in-game menu for the changes to take effect.

VanillaConfig will regenerate the config file with all default values the next time the mod loads. This is useful if your config becomes corrupted, but you'll lose any custom settings you had.

No—VanillaConfig includes a migration system that preserves your existing settings when mods update. If the mod author added new options or changed the config structure, migration code runs automatically to adapt your old config to the new format.

Yes, VanillaConfig is a library that many mods can use independently. Each mod manages its own configuration file, so there are no conflicts between them.

The mod author must have integrated VanillaConfig's screen with a menu system (like Mod Menu). Check if your mod has a config button in the mods list, or look for a settings option in the mod's own menu if it has one.

Yes—you can open the in-game configuration screen and adjust settings, and they save immediately. Some changes may require a world reload or game restart to take full effect, depending on what the setting controls.

Delete the corrupted config file and restart the game; VanillaConfig will regenerate it with defaults. If you want to keep some of your settings, try opening the file in a text editor and fixing the syntax error manually before restarting.

No—VanillaConfig is designed to be lightweight and loads configuration once at startup. It has minimal impact on game performance.

Open your config file in a text editor to see all available options and their descriptions as comments. The file format is designed to be human-readable, so you can understand what each setting does and edit values directly if needed.

It is a configuration API that lets mods easily and flexibly load and save their configs and generate vanilla-like config screens. On its own it does nothing; it only works when installed alongside mods that depend on it.

No. It is a configuration utility that adjusts vanilla Minecraft settings and gameplay values without adding new blocks or items.

It is a Fabric mod. You also need to install Fabric API alongside it.

The Modrinth project page lists 1.21.11, 26.1, 26.1.1, 26.1.2, 26.2, and 26.3. The wiki lists Minecraft 26.3 and above.

Yes. Fabric API is a required dependency, and the author states you need to install it with this mod.

No. It only does anything when installed with mods that depend on it, so you should only install it if another mod tells you to.

Yes, it is listed for both client and server.

It supports primitives (boolean, int, long, double, float), single-line and multi-line strings, lists of supported types, any Java enum, and Minecraft types such as identifiers or registry-backed values where the library version supports them.

Yes. It can generate an in-game configuration screen that maps to your config structure, with each category becoming a UI section and each entry rendered with a checkbox, slider, text field, dropdown, or list editor.

Each config file has a version, and when you change or remove options you increment the version and define a migration step. If the file version is lower than the current version, all migrations run in order until the config matches the latest structure.
