by ceemeck

What it does

The mod brings back the Multiplayer button on the main menu of the Alpha builds. Originally, those versions required a secret invite code before a player could join a server; this mod removes that requirement, so a player can type a server's IP address and connect directly. Connection works with servers that support the protocol versions these builds use.

A player who has joined a server has the last entered address saved in the options file, which makes reconnecting simpler. Installation is manual: select the Alpha instance, click Edit, open the Version tab in the instance menu, and choose the .zip file for the specific version. The mod is open source under the GNU General Public License v3.0 only. Files cover three release versions, and snapshot builds are published.

Key features

  1. Multiplayer button restored

    The main menu gets its Multiplayer button back, so the Alpha builds can open the server list again.

  2. Invite code bypass

    The secret invite code requirement is removed, and a player may connect straight to an address.

  3. Direct IP connection

    A player types the server IP and joins, with no separate invite or relay step in between.

  4. Saved server address

    The last entered address is stored in the options file, so it is easier to reach again.

No per-version build data
Modrinth lists game versions for this project (a1.0.5_01 – a1.0.14), but the source data has no build per game version and loader, so the compatibility grid is not shown.

Questions

Does Alpha Multiplayer Unlocked need to be installed on servers?

No. Servers do not need it; each player installs it for their own game.

Which loader does the mod use?

It is published for the Java Agent loader only, so the setup differs from the Fabric, Forge or NeoForge installs used by most mods.

Which Alpha versions are covered?

Files cover the Alpha builds from a1.0.5_01 onward, and the latest published file is for a1.0.14.
