Blockopolis

Install Blockopolis

Blockopolis runs on Fabric. Pick the way that suits you: a mod launcher does it all for you, or you can set it up by hand in the official launcher.

The easy way: a mod launcher

  1. Get a launcher

    Install the Modrinth App or the CurseForge App.

  2. Make a Fabric profile

    Create a new profile or instance for Minecraft 1.21.11 with the Fabric loader.

  3. Add Blockopolis

    Search for Blockopolis in the launcher and install it. Fabric API is installed with it automatically.

  4. Play

    Launch the profile and join the server.

By hand: the official launcher

  1. Run Minecraft 1.21.11 once

    In the Minecraft Launcher, start version 1.21.11 once so the game files are downloaded, then close it.

  2. Install Fabric Loader

    Download the installer from fabricmc.net, run it, pick Minecraft 1.21.11 and Loader 0.19.2 or newer, and click Install. A new "fabric-loader" profile appears in the launcher.

  3. Download the mods

    Download Fabric API for 1.21.11 and the Blockopolis jar from the download section.

  4. Drop them in the mods folder

    Put both jars in your mods folder. Create the folder if it doesn't exist.

    • Windows: %appdata%\.minecraft\mods
    • macOS: ~/Library/Application Support/minecraft/mods
    • Linux: ~/.minecraft/mods

  5. Play

    Pick the fabric-loader profile in the launcher, press Play and join the server.

Something not working? Make sure the Minecraft version is exactly 1.21.11, and that Fabric API is in the mods folder next to Blockopolis. Most crashes on startup come from one of those two.
