CooldownLib

by New

CooldownLib is a Fabric library that gives other mods a shared way to store, count and expire cooldowns, so their developers do not write timers from scratch.

FabricServer-side onlyCustom license1.21.9 – 26.2

What it does

Many mods need a cooldown for abilities, spells, weapons, special attacks, items or machines. Without a shared library, each developer tends to build the same storage, time calculation and expiration logic again. CooldownLib supplies that layer: it keeps cooldown storage for each player, allows several cooldowns per player at once, calculates the remaining time and clears entries when they expire.

The library is meant to be added as a dependency by other Fabric mods rather than used directly by players. Its API is fluent and readable, and it supports custom cooldowns with their own messages, such as a notice that an ability is still charging or unavailable. Developers can focus on gameplay while the library handles timing.

CooldownLib is server-side only, so players join a server that runs it without installing anything. It is published for Fabric only, for 1.21.9, 1.21.10, 1.21.11 and 26.2, under a custom license that is not open source.

Key features

  1. Cooldown storage per player

    Each player has stored cooldowns, and the library tracks several of them at the same time.

  2. Fluent API

    A readable, chainable API lets developers start, query and cancel cooldowns without manual timer code.

  3. Automatic expiration

    Expired cooldowns are removed by the library, so the mod using it does not need its own tick logic.

  4. Custom cooldown messages

    A cooldown can carry its own message, for example to tell a player that an ability is unavailable or still charging.

Questions

Does a player need to install CooldownLib?

Not to join a server that runs it, because the environment is server-side only. Players who use a mod that depends on it may still need the library on their client if that mod requires it.

Which loader does CooldownLib support?

CooldownLib is published for Fabric only, so a mod that depends on it must also run on Fabric.

Which game versions have files?

Files exist for 1.21.9, 1.21.10, 1.21.11 and 26.2, and the latest Fabric file is mc1.21.9 for 1.21.9, dated 2026-09-13.

What the author says

Instead of creating custom timers, HashMaps, and tick logic for every ability or item, CooldownLib provides a clean and easy-to-use API for managing cooldowns. .message("§cFireball is still on cooldown!")
