Minecraft 1.20.1, 1.21.1 కోసం OldCombatMechanics ప్లగిన్

by kernitus

Fine‑tune Minecraft combat, movement, and item balance without breaking your server. OldCombatMechanics is a free, open‑source toolkit for Spigot & Paper that lets you mix 1.8‑style snappiness with modern features, per world and per player. It is built for PvP networks, minigames, BedWars/SkyWars-style games, duels, KitPvP, practice arenas, and mixed PvP/PvE worlds that need different combat rules in different places.

Why servers pick OCM ✨

• 🧩 Modular: enable only what you need: cooldowns, tool damage, knockback, shields, potions, reach, sounds, more.
• 🚀 Performant: lean listeners only enabled as needed; reflection lookups are cached and recurring tasks are minimised (shared where possible) to keep tick time low on busy PvP servers.
• 🗺️ Modesets: ship different rules for different worlds or players; perfect for mixed PvP/PvE, minigames, or duels.
• ⏪ Backwards‑friendly: runs on Java 8+, supports 1.9 to latest; integrates cleanly with PlaceholderAPI and PacketEvents.
• ✅ Tested for you: live integration tests run real Paper servers across multiple versions every build.
• 💸 Zero cost: fully open source, optional basic telemetry (bStats only), no paywalls.

Quick start ⚡

• Drop the jar into plugins/ (Spigot or Paper-derivatives 1.9+).
• Restart and edit config.yml to pick your modules and modesets.
• Use /ocm reload to apply changes instantly.
• Hand players /ocm modeset to let them choose their ruleset.

🧰 Modesets

• Per-player/per-world presets that decide which features are active; each world has an allowed list and a default modeset.
• Let players pick ( /ocm modeset ) to run, for example, 1.8-style PvP in an arena world whilst keeping vanilla rules in survival.

⚙ Configurable Features

🔌 Compatibility & Testing

• OCM targets Spigot 1.9+ and runs on Java 8 and up.
• We stick to Spigot/Paper APIs for forward compatibility; NMS/reflection is used only when necessary.
• Integration tests boot real servers on 1.9.4, 1.12, 1.19.2, and 1.21.11 each build to verify behaviour.
• Most plugins work fine with OCM. Explicitly tested integrations include PlaceholderAPI (see wiki).
