About the Default Options mod

This mod can be used by modpack developers to distribute default options and keybindings without overriding user changes on every modpack update.

Instead of shipping the options.txt directly, you will ship a "defaultoptions" folder in your modpack which contains the defaults previously saved through the /defaultoptions command.

This mod requires Balm, which must be installed alongside the mod.

  • On the first run, users will start out with the options you configured - and future changes won't be overridden on updated
  • Keybinds configured by the modpack will be set as new defaults, meaning changes made by users will persist even on updates
  • The server list will be pre-populated with the server list provided by the modpack (and user changes will persist on updates, still)
  • Configure the options, keybinds and server list as you would like them to be shipped in the modpack
  • Join any world and run "/defaultoptions saveAll" to save your current options in the defaultoptions folder (located in the config folder where it should remain)
  • Do not include the options.txt and servers.dat from the root directory in your modpack
  • Fresh installations (meaning no existing options.txt) will now start out with your default options

How to install Default Options

With Millida Launcher

  1. Install Millida Launcher

    The launcher is free: download it at millida.net/launcher and sign in with any nickname.

  2. Click “Install” on this page

    The launcher opens and installs the mod for Minecraft 1.18–26.3 on Fabric, Forge or NeoForge automatically, together with its dependencies: Balm, Fabric API.

  3. Launch the game

    A profile with it appears in the launcher: click “Play”.

Manually

  1. Install Fabric, Forge or NeoForge

    The loader must match the game version of the mod file, for example Minecraft 26.3. After installing it, a separate profile appears in your launcher.

  2. Download the file for your version

    In the version list above, pick the file defaultoptions-neoforge-26.3-26.3.0.1.jar (108 KB) for your game version and loader.

  3. Put it in the mods folder

    The folder is inside .minecraft (Windows: %appdata%\.minecraft\mods). If it does not exist, create it. Required dependencies go there too: Balm, Fabric API.

  4. Launch the loader profile

    Open “Mods” in the main menu: Default Options should be in the list.

Default Options works on the player’s side only: there is no need to install it on a server.
