TimelessLib
TimelessLib is a Fabric library of timing tools, covering animations, cooldowns, countdowns, a scheduler and interpolation for other mods to build on.
What it does
The library provides shared time-based utilities that other mods can call instead of writing their own. Its feature list includes an animation system, double and Vec3 channels for storing values that change over time, an interpolation system for smooth transitions, cooldown and countdown helpers, a scheduler for running tasks after a delay, and general time utilities.
Two catalog mods require TimelessLib: Animated Mojang Logo and Barless. Players install the library next to those mods. The mod is published for Fabric alone, across 48 release versions 1.14 – 26.3, and the code is open source under the zlib License.
The latest Fabric file is 2.0.1-fabric-26.3, dated 2026-10-04, and the project was first published on 2025-12-09. Public links exist for the source code, the issue tracker and a wiki, and the version list is shown on the versions tab of the project page.
Key features
Animation system
Lets other mods run timed animations that play out over a set duration and can be reused across features.
Double and Vec3 channels
Channels store a single number or a three-part vector that changes over time, so a mod can track a value across ticks.
Interpolation system
Computes values between two points, giving a mod smooth movement or fading without manual per-tick math.
Cooldowns and countdowns
Helpers for counting time down to an action or until a timer expires, useful for abilities and delayed effects.
Scheduler and time utilities
A scheduler runs tasks after a delay, and the time utilities convert and handle durations for the calling mod.

Timed animations in other mods

Who it’s for: Mod developers who need timing, interpolation or scheduling helpers, and players who install a mod that requires TimelessLib.
