Frequently asked

Does Advanced Wall Climber API work on Minecraft 1.21.11?

Yes. 1.21.11 is the newest Minecraft version Advanced Wall Climber 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 Advanced Wall Climber API support?

Everything the author has declared, from 1.20.1 up to 1.21.11. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install Advanced Wall Climber API on the client or the server?

Both. Every player needs it installed and so does the server, so anyone joining without it will be refused.

Which loader does Advanced Wall Climber API need?

Fabric, NeoForge, Forge. A build for one loader will not load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for Advanced Wall Climber API?

Java 21 or newer, because that is what the newest Minecraft release it supports requires. The requirement comes from the game rather than from the mod itself.

What licence is Advanced Wall Climber API under?

LicenseRef-All-Rights-Reserved, 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 Advanced Wall Climber 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 Advanced Wall Climber API safely?

From the author's own page on Modrinth, which is where the data here is synced from. MCReference never mirrors, re-hosts or repackages a file: every download button points at the original source, so you get exactly what the author published.
