This project adds a client-side companion for Open Parties and Claims that turns its command-only party management into a full in-game GUI for members, invites, and allies.
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:
| Branch | Minecraft | Loader(s) | Open Parties and Claims | Cloth Config API | Fabric API | Forge Config API Port |
|---|---|---|---|---|---|---|
1.20.1/main |
1.20.1 | Fabric | ≥ 1.20.1 | ≥ 11.x | 0.92.11+1.20.1 | Fabric only |
1.21.1/main |
1.21.1 | Fabric, Forge, NeoForge | ≥ 1.21.1 | ≥ 15.x | 0.105.0+1.21.1 (Fabric) | Fabric and Forge (not needed on NeoForge) |
1.21.11/main |
1.21.11 | Fabric, Forge, NeoForge | ≥ 1.21.11 | not used | 0.139.5+1.21.11 (Fabric) | Fabric and Forge (not needed on NeoForge) |
26.1.2/main |
26.1.2 | Fabric, Forge, NeoForge | ≥ 26.1.2 | not used | 0.145.4+26.1.2 (Fabric) | Fabric and Forge (not needed on NeoForge) |
26.2/main |
26.2 | Fabric, Forge, NeoForge | ≥ 26.2 | not used | 0.159.0+26.2 (Fabric) | Fabric and Forge (not needed on NeoForge) |
26.3/main |
26.3 | Fabric, Forge, NeoForge | ≥ 26.3 | not used | 0.162.0+26.3 (Fabric) | Fabric and Forge (not needed on NeoForge) |
Notes:
- Cloth Config was dropped starting with the
26.1.2/mainbranch (and on1.21.11/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/mainand26.3/mainalso need Java 25 (bundled with the game; only relevant when building from source).
