EventsLib Mod (26.1.2, 1.21.1) – Custom Potion Effect Triggers

EventsLib Mod provides extra event listeners for potion effects in Minecraft. This library mod works in the background and does not add any standalone items or blocks to the world. Other mods rely on this system to check active status effect timers and trigger custom actions when specific effects end.

Features:

• Runs quietly in the background without changing vanilla items or blocks.
• Provides special events to monitor active potion effect duration percentages on any mob or player.
• Allows other mods to access effect instances and target mob data during effect ticks.
• Triggers clean cleanup methods right when a potion effect wears off.
• Helps dependent mods manage custom player attributes and powers without heavy performance costs.

Requirements:

NeoForge Required
