Open Parties and Claims: Combat Log

⚔️ OPAC: Combat Log

Stop claim-camping and PvP abuse. A lightweight, server-side combat logging mod built specifically for Open Parties and Claims (OPAC) with dedicated support for OPAC: Warfare.

❓ Why OPAC: Combat Log?

If you’ve ever hosted an SMP or PvP server with Open Parties and Claims, you know the drill:

• A player starts a duel in the wild, takes a hit, and immediately sprints across the border into an OPAC claim or safezone where PvP is disabled.
• Attackers or defenders toss Ender Pearls or eat Chorus Fruit right into safezones or ally claims to escape punishment.
• Combatants hot-stash loot into Ender Chests, log out to avoid losing gear, or use /spawn and /home.

Standard combat log mods have zero awareness of OPAC claims or safezone subclaims. OPAC: Combat Log bridges this gap completely.

🤝 Companion Mod: Open Parties and Claims: Warfare

OPAC: Combat Log fully integrates with Open Parties and Claims: Warfare:

• War Chunks as Wilderness: Contested chunks under active war or siege are dynamically treated as wilderness:
  • Players fighting inside war zones will never be knocked back or ejected by claim boundaries.
  • Ender Pearls and Chorus Fruit can be freely utilized within contested siege sectors.
  • Players in combat within war chunks are prevented from fleeing into peaceful, uncontested claims.
• Zero Hard Dependency: The mod automatically activates this behavior when Warfare is detected on the server, while running without issues if Warfare is absent.

✨ Core Features

🛡️ Native OPAC Claim & Safezone Integration

• Anti-Safezone Camping: If combat starts in unclaimed territory (wilderness or active war chunk), tagged players are physically barred from entering ANY claimed land or safezone.
• Origin Claim Memory: If a battle starts inside a claimed base, players can fight within that claim, but are prevented from fleeing to neighboring third-party claims.
• Smart Boundary Pushback: Trying to sprint-jump, ride a vehicle, or exploit client prediction into a forbidden claim results in a clean server-side pushback with zero-velocity rollback and barrier audio cues.

🪓 Anti-Exploit Enforcement

• Ender Pearl & Chorus Interception: Pearls and Chorus Fruit cannot land or teleport players inside forbidden claims while in combat.
• Flight Disabler: Elytra, Creative, spectator, and /fly flight are instantly revoked upon dealing or taking PvP damage (and safely restored when combat expires).
• Anti-Stashing (Container Lock): Opening Ender Chests, chests, shulker boxes, and barrels is blocked while tagged.
• Portal & Command Lock: Nether/End portal traversal and escape commands (/spawn, /home, /warp, /tp, /tpa, claim management commands) are blocked.

💀 Combat Logging & Fair Play

• Combat Logout Punishment: Quitting the game while in combat immediately kills the player.
• Accurate Attacker Credit: Drops player inventory at the logout coordinate and attributes the kill (and death message) directly to the opponent.
• Untag on Kill: Finishing off your opponent instantly clears your combat tag — no waiting around when you win!

⚡ Minimalist & Server-Side

• 100% Server-Side: Clients don’t need any mod installed. Pure vanilla clients can connect freely.
• Clean Actionbar Timer: An unobtrusive countdown timer on the actionbar (⚔ In Combat: 15s) keeps players informed without screen clutter.
