APTweaks: Gamerules (11.x Classic)

by Kaworru

APTweaks: Gamerules (11.x Classic) is a server-side Forge and NeoForge module that adjusts selected game rules while the server runs, based on its current load.

ForgeNeoForgeServer-side onlyMIT LicenseOpen source1.18.2 – 1.21.1

What it does

The module watches server load and changes game rules such as random tick speed, entity cramming, raid frequency, patrol and wandering trader spawns, and insomnia when the server is under high load. The aim is to keep TPS and FPS steadier during busy periods. Changes apply only to the rules the module manages, and the server owner decides which of them are touched through the config files.

Only the server needs the mod: players join without installing anything, and the server runs it alone. It is one of the APTweaks modules, so Required dependencies: APTweaks: Core (11.x Classic) must be installed alongside it. APTweaks: Items (11.x Classic), APTweaks: Player (11.x Classic) and APTweaks: Spawn (11.x Classic) are optional and can be added to extend the set of tweaks. The mod is open source under the MIT License, and builds cover 1.18.2 – 1.21.1 across Forge and NeoForge.

Key features

  1. Dynamic random tick speed

    The random tick speed is raised or lowered according to the load measured on the server.

  2. Entity cramming control

    The entity cramming rule is tuned to reduce lag spikes caused by crowded areas.

  3. Spawn and raid controls

    Raids, patrols, wandering traders and insomnia are adjusted when the server is under high load.

  4. Built-in debug output

    A debug readout shows what the optimizer is changing, so the owner can check its effect.
