OpenPAC ComputerCraft United

OpenPAC ComputerCraft United (OPCCU) enhances OpenPAC with CC:Tweaked support, fixing turtle/computer compatibility

OpenPAC ComputerCraft United (OPCCU)

Overview

OpenPAC ComputerCraft United (OPCCU) is a server-side NeoForge mod for Minecraft 1.21.1 that expands Open Parties and Claims (OpenPAC) with better automation support, improved claim management, and survival-friendly tools.

The primary goal is to eliminate compatibility issues between CC:Tweaked and OpenPAC, while providing players with an easier and more flexible claiming experience.


Target Platform

  • Minecraft 1.21.1

  • NeoForge

  • Java 21

  • Open Parties and Claims (OpenPAC) 0.27.5+

Main Objectives

🤖 CC:Tweaked Compatibility

Fix compatibility issues between OpenPAC and CC:Tweaked by:

  • Allowing turtles to interact across OpenPAC claims (configurable).

  • Allowing computers to function correctly when OpenPAC would otherwise block them.

  • Supporting CC:Tweaked fake players without granting actual Minecraft OP permissions.

  • Resolving OpenPAC-related networking/HTTP restrictions that interfere with CC:Tweaked functionality.

  • Preserving OpenPAC's protection system for everything outside the configured compatibility behavior.
