Open Parties and Claims PvP Support
by ElocinDev
With Open Parties and Claims PvP Support, party members can be prevented from damaging each other, and each player can switch personal party PvP on or off.
What it does
Installed on a server, the mod turns off player-versus-player damage between members of the same party from the Open Parties and Claims system. Players outside the party keep normal PvP rules. Its only function is this party-level protection, plus an optional personal toggle that is available on Fabric.
On Fabric, the /opacpvp command lets a player turn personal party PvP on or off. When a player fights a party member, both players need personal PvP enabled before either can damage the other. Default values and the whole toggle feature can be changed in the config. The mod requires Necronomicon API and Open Parties and Claims. It is server-side only, released under All rights reserved, and is not open source. Files exist for 1.20, 1.20.1, 1.21 and 1.21.1 on Fabric, Forge and NeoForge, with 1.0.1 as the latest file on each loader.
