Install One-Way in GDLauncher

One-Way runs on Fabric. Pick whichever your existing instance uses, or create a new one. GDLauncher installs the correct loader automatically.

Install on Fabric

  1. Open GDLauncher and create a new instance (the + button on the Library page).
  2. Pick the Fabric loader and a Minecraft version that One-Way supports (1.21.11, 1.20.4 are common choices).
  3. Open the new instance, go to the Addons tab, and click Add Addons.
  4. Paste the Quick Install ID #one-way, find One-Way in the results, and hit Download. GDLauncher pulls dependencies automatically.
  5. Hit Play. That's it.

Before you install

Make sure your Minecraft version matches what One-Way supports. As of the latest release, 1.21.11, 1.20.4 are supported. One-Way only runs on Fabric; mods built for other loaders won't work. GDLauncher checks compatibility for you and won't install something incompatible with the instance you've chosen.
