Shard Booster Timer - DONUT SMP

by RvlProjects

Shard Booster Timer, a Fabric client mod for DONUT SMP, puts an on-screen countdown next to the vanilla effects.

FabricClient-side onlyMIT License1.21.1 – 1.21.11

What it does

The mod displays a 24-hour countdown for the Shard Booster potion, which is a server effect alongside the vanilla effects. It detects when a Shard Booster is drunk and starts the timer on its own, without any command. The remaining time is kept between play sessions, so a countdown carries over after the game is closed and reopened. Only the client needs the mod, and Fabric API is required alongside it. Builds cover 1.21.1 – 1.21.11, and the mod is released under the MIT License but is not open source.

Key features

  1. Visible potion timer

    A timer is shown on screen for the Shard Booster potion effect, beside the vanilla effects.

  2. Automatic detection

    Drinking a Shard Booster starts the 24-hour countdown without any manual input from the player.

  3. Saved remaining time

    The time left on the countdown is remembered between play sessions, so it resumes after a restart.
