Arc Lib
Arc Lib is a library Minecraft mod with 84.7K downloads on the Orca catalog. It runs on Fabric, Forge and NeoForge, so it slots into a matching Minecraft profile without hand-patching anything. Arc Lib is free to download and free to host on Orca: press Play and Orca launches Minecraft with Arc Lib already installed, or host it on a free server to play with friends. There is no control panel and no config files to edit, and no command line to learn. Describe what you want in plain English and Orca installs Arc Lib along with the loader and Minecraft version it needs, then you and your friends are playing in minutes.
Data driven action, reward, condition library.
How to install Arc Lib
Two ways to add Arc Lib to Minecraft. One takes a click.
- Click Play below. Orca installs Arc Lib with Fabric, Forge and NeoForge and the right Minecraft version, then launches straight into the game.
That’s it. Nothing to download or configure.
- Download the latest Arc Lib file from Modrinth for your Minecraft version.
- Install Fabric, Forge and NeoForge and launch Minecraft once so the loader profile is created.
- Drop the downloaded .jar into your mods folder (the mods folder inside .minecraft, or your server's mods folder).
- Add any libraries Arc Lib depends on (the Modrinth page lists them) into the same folder, then start Minecraft on the Fabric, Forge and NeoForge profile.
