opac-ui

A client-side mod that adds an in-game party management GUI for Open Parties and Claims using Cloth Config's tabbed-list UI.

Requirements

• Minecraft 1.20.1 (Fabric)
• Fabric API
• Forge Config API Port (Fabric only - required by Open Parties and Claims' Fabric build)
• Open Parties and Claims (≥ 1.20.1)
• Cloth Config API (≥ 11.x)

Usage

Press P (configurable in key bindings) to open the party manager.

• Not in a party - Create Party button
• In a party - Tabbed screen with three tabs:
  • Members - view ranked member list; promote/demote, kick, and transfer ownership (permission-dependent)
  • Invite - invite players by name; revoke pending invites
  • Allies - view allied parties; unally (permission-dependent)

Branches

This mod is maintained as one branch per Minecraft version - see each branch's own README and CHANGELOG on GitHub for loader-specific setup notes.

opac-ui always requires Open Parties and Claims

• it's a client-side add-on, not a standalone mod. Exact versions per branch:

Notes:

• Cloth Config was dropped starting with the 26.1.2/main branch (and on 1.21.11/main, which is built from it) since it no longer ships a Forge build - the party screen there is built entirely with Minecraft's own UI components instead.
• 26.1.2/main, 26.2/main and 26.3/main also need Java 25 (bundled with the game; only relevant when building from source).
