Effect Monitor
by Shantek
Effect Monitor is a client-side Fabric utility that warns players before a potion effect runs out, using configurable alerts.
What it does
When a potion effect is close to expiring, the mod can show a notice before it fades, so a player has time to drink another potion or reposition. Alerts fire at custom time thresholds, such as 60 seconds, 30 seconds and 5 seconds, and each threshold can be set separately. A notice can appear as a title on screen or as an action bar message above the hotbar, and an optional sound cue can accompany it.
Effect Monitor can be limited to positive effects, such as Strength or Night Vision, or to negative ones, such as Poison or Weakness, so the alerts cover only the effects a player cares about. An in-game configuration menu holds these settings. The mod runs on the client alone, and it is published for Fabric only, with files for 26.3 and eight other game versions 1.21.5 – 26.3, under the GNU General Public License v3.0 or later. The code is open source.
Key features
Custom time thresholds
Alerts can trigger at chosen remaining times, such as 60, 30 and 5 seconds, instead of one fixed warning.
Title or action bar notices
A warning can be displayed as a title on screen or as an action bar message, depending on the player's preference.
Optional sound cue
An audible cue can accompany each alert, so a warning is noticed even when the player is not looking at the HUD.
Effect filtering
Tracking can be restricted to positive effects or to negative effects, leaving the rest out of the alerts.
In-game configuration menu
All options are changed from a menu inside the game, without editing configuration files by hand.
