Improved:

• Villager AI: Optimized pathfinding/AI logic to reduce RAM usage.

• Projectile Cleanup: Any projectile shot by any mob immediately despawns upon hitting the ground.

Added:

Command: /opt entitylim (Default N = 40).

Named projectiles/thrown items (e.g., custom Tridents) are excluded from being despawned.

How it works:

• Limits active projectiles shot by a player to N. Once exceeded, the oldest projectile despawns.

• Limits active projectiles shot by player-placed dispenser/machine blocks to a separate cap of N.

• The limits are independent, allowing up to 2N total active projectiles per player across both sources.

NeoForge 1.21.1

📝 Easy Server OPT (ESO) - Changelog

This update focuses exclusively on refactoring the underlying Event Handling architecture to strictly follow Forge Mod Loader standards. All server optimization features and logic remain 100% unchanged.

🔄 Refactoring Changes

Automated Event Registration: Replaced manual MinecraftForge.EVENT_BUS.register() calls with Forge's @Mod.EventBusSubscriber class-level annotations across the mod. Static Event Methods: Converted all @SubscribeEvent methods to public static to comply with the automatic subscriber requirement. Config Separation: Moved all configuration loading events (Load/Reload) out of the main mod class and into ModConfig.java, utilizing the MOD event bus for cleaner architecture and separation of concerns.

🚀 Features Status

All optimization mechanics continue to work flawlessly in the background exactly as before:

✅ TPS-based auto-optimization (Runs silently every 2 seconds).

✅ Aggressive XP merging and chunk mob limits (40 max).

✅ Server sleep/tick-pause on empty.

✅ Smart Villager AI freezing.

✅ All /opt commands.

OPTServer v1.09 - Release Changelog

A lightweight, powerful server-side optimization mod for Minecraft Forge 1.20.1.

What's New in v1.09

1. Auto "Anti-Tick-Slip"

Automatic World Time Freeze: When the server becomes empty, the mod persistently saves the game time (gameTime/dayTime) and the real-world logout timestamp. Auto-Restoration: Upon player login, if the server was empty for >= 5 minutes, the mod automatically rolls back/restores the game time and day time to the exact moment of logout. Safety Window: If players reconnect in under 5 minutes (quick crashes or restarts), time proceeds normally to prevent rollback issues.

2. Built-in Lag Profiler (/opt find)

Instantly scan loaded chunks across all dimensions. Displays the Top 3 Chunks with the highest entity count (dimension, chunk coordinates, and exact block coordinates) so you can hunt down mob farms or lag spots. Displays the Top 5 most numerous entity types globally.

3. Dynamic Mob Capper (/opt moblim )

Dynamically limit the maximum number of Mob entities allowed inside any single chunk. New spawns in overloaded chunks are automatically canceled (ignores custom-named mobs/pets so your named entities are always safe). Adjusted in-game via /opt moblim .

4. Smart Villager AI Optimizer

Automatically freezes the pathfinding and brain tick processing (NoAi = true) of stationary Villagers (speed ~0) to eliminate trading hall lag. Seamless Trading: Automatically restores full AI (NoAi = false) for 60 seconds whenever a player interacts (right-clicks) with them, allowing smooth trades, restocking, and job updates before refreezing them.

5. Critical Bug Fix

Fixed Inactive Event Loop: Resolved a major issue where the automatic dynamic optimizer (onServerTick and onServerStarting) never executed because the CommandsHandler class lacked the @Mod.EventBusSubscriber annotation. Auto-mode now works perfectly on server startup!

Auto Mode (Default): Automatically runs on startup. Dynamically monitors TPS and adjusts settings — no manual setup required.

Manual Commands (Optional): All existing commands (/opt dis, /opt clear, etc.) still work for manual control if needed.

XP Infinite Merge: /opt xp <on/off> to toggle high-performance XP stacking.

Simplified Config: No tuning or logic options anymore. Config file now only contains a pre-filled default trash item list — works out of the box. Advanced users may optionally customize or extend the list if desired.

Simplify Commands

/opt dis on/off

/opt weather on/off

/opt daylight on/off

/opt randomtick on/off

/opt mobai on/off

/opt clear
