Silver's Effects Library | EL
by ItzSilver_
Silver's Effects Library | EL is a library for custom status effects, letting a pack or developer add, change and clear them with commands.
What it does
Effects added through the library can be set, extended, shortened or cleared with commands. Commands can give a player a bleed effect for 10 seconds, set Frostbite to 4 seconds or remove a 15-second stun. The library also lists which effects and modifiers are available to command, so pack authors can look up names before writing a command.
Modifiers cover duration changes: an effect's duration can be increased, set to a specific length or reduced, and the remaining time can be counted. Sprinting and biome-related modifiers are included among the modifier options. The library is a server-side dependency, so players join without installing it, though a server owner needs it running for those effects to work.
Silver's Effects Library | EL requires Silver's Datapack Tags Library | DTL and can use Silver's Project Info | PI as an optional companion. It is published for Fabric, Forge, NeoForge and Quilt, plus as a data pack, across 17 release versions, 1.21 – 26.3, and is not open source; it is released under All rights reserved.
