Ornithe Standard LibrariesRequired. A set of libraries for modding with Ornithe.

Frequently asked

Does Legacy Fabric API work on Minecraft 1.12.2?

Yes. 1.12.2 is the newest Minecraft version Legacy Fabric API declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Which Minecraft versions does Legacy Fabric API support?

Everything the author has declared, from 1.3 up to 1.12.2. The full list is in the table above, with the Java runtime each version needs next to it.

Which Java version do I need for Legacy Fabric API?

Among the supported Minecraft releases above, the highest recorded requirement is Java 8 or newer. Use the requirement for the exact Minecraft version you run; previews and snapshots may differ.

What does Legacy Fabric API need to run?

It declares Ornithe Standard Libraries as required, so that has to be installed alongside it or it will not load. Each one is linked in the dependencies section above.

What licence is Legacy Fabric API under?

Apache-2.0, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install Legacy Fabric API?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the mod and Minecraft all have to be on the same version, which is the usual reason a mod does not appear in game.

Where do I download Legacy Fabric API safely?

Start with the author's page on Modrinth, which is where the data here is synced from. MCReference does not host or repackage files. When available, recorded download links go to the source for that release; verify the publisher, filename and any available checksum before running it.
