SIAc

by TanuchOY

SIAc is a Fabric client-side companion to the SIA2 mod, used to connect a player's client with the Rivalation server's gameplay systems.

What it does

Installed on the client, SIAc acts as a bridge between the player and the server-side features that SIA2 depends on. It is described as a specialized technical modification developed for SIA2 and tied to the Rivalation server infrastructure, so it is meant for players who use SIA2 on that server rather than as a general-purpose addition.

SIAc is meant only for people who play SIA2, and part of its work depends on a closed server-side plugin that the public cannot inspect. Without that specific server environment, the mod provides no features that affect single-player play or other servers. Fabric API is required, and the mod is released under the MIT License, though it is not open source. Files are published for Fabric only, and the only supported game version is 1.21.6, with 4.1.4 as the latest file, first released on 2026-04-24.

Key features

  1. Media synchronization

    The server can stream visual media and push it to the player's screen, adding an atmospheric layer to the session.

  2. Integrity checks

    A built-in module checks the client-side modifications a player has installed, to help keep play fair on the server.

  3. Server hooks

    Custom server scripts and story-related triggers can call into the client through the hooks the mod provides for advanced gameplay mechanics.

  4. Optimized network packets

    Specialized network packets travel between the client, SIA2 and the server plugin, handled so that they do not affect other gameplay.

Questions

Does SIAc need Fabric API?

Yes. Fabric API is listed as a required dependency, so it must be installed alongside SIAc on Fabric.

Does SIAc have to be installed on the server?

No. The environment is client-side only, so only the client needs the mod, and the server-side functions come from a private plugin rather than from this file.

Will SIAc change a single-player world?

No. Without the specific server environment it was built for, the mod provides no features that affect single-player play or other servers.
