OPAC Fixes

A Fabric Minecraft mod that provides claim protection compatibility fixes for Open Parties and Claims (OPAC) when used alongside other popular mods.

Overview

Some mods implement custom explosion or block placement/breaking mechanics that bypass standard Fabric event listeners, allowing players or mobs to bypass OPAC claims protection. This mod surgically intercepts these behaviors to ensure that claims remain protected.

Features

  • Mutant Monsters: Prevents mutated explosions (e.g. Mutant Creepers) from destroying blocks and harming entities inside protected claims.
  • Supplementaries: Prevents Red Merchants' bombs from bypass griefing blocks and entities in protected claims.
  • Botania: Prevents the Ring of Loki from bypass-placing or bypass-breaking blocks inside protected claims using blueprints.
  • Conditional Loading: Compatibility mixins for Mutant Monsters, Supplementaries, and Botania only load if the respective mods are detected at runtime.

Installation

  1. Ensure you have Fabric Loader and Fabric API installed for Minecraft 1.20.1.
  2. Requires Open Parties and Claims (OPAC) to be present.
  3. Drop this mod into your mods folder.
