Description
CobbleOptimizer
A server-side Fabric mod for Minecraft 1.21.1 that optimizes Cobblemon (the Pokemon mod) entity performance based on server load (TPS). It has 4 main
features:
- Tick Throttle — Reduces how often distant/unimportant Pokemon entities are ticked. When the server TPS drops, Pokemon far from players get their tick rate reduced, saving CPU cycles.
- AI Freeze — Completely freezes the AI of Pokemon entities that are far from any player. If no one is nearby to observe them, there's no need to run their pathfinding and behavior logic.
- Adaptive Spawn — Dynamically adjusts Pokemon spawn rates based on current server TPS. When the server is struggling, fewer Pokemon spawn; when it's healthy, spawns return to normal.
- Batch Despawn — Removes excess Pokemon entities in bulk when the server is overloaded, prioritizing removal of unimportant ones (non-shiny, non-legendary, unowned, not in battle).
Shared Infrastructure
- TPS Monitor — Continuously tracks server TPS to inform all features.
- Player Tracker — Caches player-to-entity distances so multiple features can cheaply check proximity.
- Config — TOML-based configuration with in-game commands (/cobbleoptimizer) to tweak thresholds on the fly.
In short
It's a performance optimization mod that keeps Cobblemon servers running smoothly by intelligently scaling back Pokemon entity processing when the server is under load, while protecting important Pokemon (shinies, legendaries, battling, owned) from aggressive optimization.
