It won’t fix all lag by itself, but it can noticeably reduce it when used alongside well coded plugins and a solid server setup. It is not intended to resolve issues caused by low quality or poorly configured plugins.</p> </div> ## ⚡ Requirements & Compatibility - **Java:** 21 or later [(use version 1.5.3 for java 8 support)](https://modrinth.com/plugin/lagfixer/version/1.5.3) - **Server:** Bukkit/Spigot/Paper, hybrid Forge, etc. - **Version range:** `1.13.2` – `26.2` ## 🧩 Modules Overview | Module | Impact | Description & Features | | :--- | :---: | :--- | | **MobAiReducer** | 🔴 **VERY HIGH** | Replaces creature movement to optimize behavior. Disables unnecessary PathFinders. Crucial for massive animal farms. | | **EntityLimiter** | 🔴 **HIGH** | Restricts the number of entities per chunk. Prevents excessive entity accumulation. | | **LagShield** | 🔴 **HIGH** | Monitors server load and dynamically adjusts settings during latency spikes. | | **ExplosionOptimizer**| 🔴 **HIGH** | Limits explosion power and chain reactions (TNT, creepers, End Crystals). | | **ItemsCleaner** | 🟡 **MEDIUM** | Cleans up old items on the ground. Includes `/abyss` command for players to retrieve lost items. | | **RedstoneLimiter** | 🟡 **MEDIUM** | Disables demanding Redstone clocks to prevent server overload and crashes. | | **VehicleMotion** | 🟡 **MEDIUM** | Optimizes boats and minecarts. Automatically removes chest minecarts spawned in mineshafts. | | **AbilityLimiter** | 🟡 **MEDIUM** | Limits rapid Trident and Elytra usage to prevent excessive, fast-paced chunk loading. | | **ConsoleFilter** | 🟢 **VISUAL** | Filters console messages based on predefined rules. Enhances log clarity and reduces console clutter. | ## 🛠️ Features & Integration <details> <summary><b>🔌 Supported Plugins</b></summary> - [PlaceholderAPI](https://www.spigotmc.org/resources/6245/) - [WildStacker](https://bg-software.com/wildstacker/) - [UltimateStacker](https://songoda.com/product/16) - [RoseStacker](https://www.spigotmc.org/resources/82729/) - [LevelledMobs](https://www.spigotmc.org/resources/74304/) - [Spark](https://spark.lucko.me/download) </details> <details> <summary><b>📊 Placeholders</b></summary> | Placeholder | Description | | :--- | :--- | | `%lagfixer_tps%` | Current ticks per second (TPS) | | `%lagfixer_mspt%` | Current milliseconds per tick (MSPT) | | `%lagfixer_cpuprocess%`| Current process CPU usage | | `%lagfixer_cpusystem%` | Current system CPU usage | | `%lagfixer_worldcleaner%`| Countdown to the next world clean | </details> <details> <summary><b>💻 Commands</b></summary> - `/lagfixer` - Main plugin command - `/abyss` - The place where deleted items go (recovery) </details> ## 🛡️ Privacy & Data Collection This plugin sends error reports, Spark profiler data and bStats metrics to the author's server solely for plugin optimization and finding new performance improvements for your server.

* Fixed the **`ignore_models`** option in the WorldCleaner module. * Implemented **asynchronous plugin reloading** for `/lagfixer reload` to avoid ~2-tick pauses caused by loading extensive configuration data. * Fixed an issue where items given via `/give` appeared to “duplicate” and remained on the ground (un-pickable) when **`disable_item_despawn`** was enabled. * Fixed the hardware menu on environments that do not support hardware detection, such as **WSL**. * Added new **alert settings** for WorldCleaner: * You can now choose the alert mode (**message**, **actionbar**, or **both**). * Added the ability to define the **permission required** to receive alerts.

* Improved **subcommand handling** for the `/lagfixer` command. * Fixed an issue where the **module configuration menu** stopped working after making changes. * **Optimized the module list and configuration menus** by removing the function that cleared and rebuilt the inventory each time; unchanged items now remain persistent between updates. * **Optimized reflection** in `DeprecatedBukkitSupport` for unsupported versions that rely on NMS class adaptation. * Added a new **"others" limit type** in **EntityLimiter**, which restricts the spawning of entities other than creatures, items, vehicles, and projectiles (e.g. armor stands). * Stopped using **Google Commons’ ImmutableList** to improve compatibility with older Minecraft versions that do not support this library. * Fixed an issue in **ErrorsManager**, which previously failed to report plugin errors properly. * Changed the **resource channel** from **Alpha** to **Release**.

- AbilityLimiter: Fixed an issue on Spigot servers where setting item cooldowns required synchronization. This issue did not affect Paper servers. - EntityLimiter: Added the `overflow_purge` option, which automatically removes excess entities that exceed the per-chunk limits. This helps prevent lag caused by players intentionally spawning large numbers of entities to overload the server.

- Optimized Pathfinder Tempt: Instead of creating a new TargetingConditions object every time, the goal now reuses already prepared ones for each mob. Less object creation = better performance and less garbage collection. - Faster targeting for versions 1.16.5–1.20.4: Previously, selecting the correct targeting logic used a bunch of instanceof checks **O(n)**. Now it's done using a direct Map lookup **O(1)**, which is much faster, especially with many mobs active. - More mobs now support tempting behavior for versions 1.16.5–1.20.4: Added missing tempt options for several mobs that weren’t handled before, better coverage and more consistent AI support. - Fixed pathfinder list sync for 1.16.5: Could cause server crash in some cases.

- We have removed support for servers running on Folia-based forks. Support for Folia was highly problematic and significantly limited the capabilities of the LagFixer plugin, especially in terms of increasing the asynchronicity of its methods. Since the engine itself is designed to be asynchronous, LagFixer cannot operate without impacting gameplay by executing on other threads.
