Cooper Is Modpack — Server Pack
A minimal Fabric server pack for Minecraft 1.21.10, containing only the essential logic and world-generation data required for the Cooper Is Modpack.
Short Summary
This pack is the backend foundation for your server. It ensures that world generation (biomes/structures) and gameplay mechanics (tree felling/mob drops) perfectly match the client experience while removing all heavy visual and UI mods to maximise Server TPS and stability.
🎯 Purpose
- Parity: Ensures clients see the same custom biomes and structures.
- Stability: Stripped of all client-only rendering mods to prevent server crashes.
- Compatibility: Pre-configured for multiplayer security and performance.
🧭 World Generation Parity
All required world-gen data is included, so the server handles terrain correctly:
- Dimensions: Terralith, Incendium, and Nullscape.
- Structures: All Dungeons & Taverns overhauls (Strongholds, Fortresses, Temples).
- Villages: CTOV and Beekeeper Huts.
⚙️ Server-Side Mechanics
Core gameplay features handled by the server:
- FallingTree: Server-side timber physics for all players.
- Right Click Harvest: Agricultural quality-of-life for crops.
- Economy/Utility: Rotten Leather recipes, Animal Feeding Troughs, and Mob Head drops.
- Mobs: Friends and Foes logic for new mob spawns.
- Discord Integration: Ability to chat between your Discord and Minecraft servers.
🛠️ Performance & Security
Tools to keep your server running smoothly:
- Spark: Professional-grade profiling to diagnose and fix lag.
- Packet Fixer: Prevents players from being disconnected due to large data packets.
- AuthMe: Integrated security for player authentication.
