A small library for making MobEffects easier to use, and more dynamic

 

What is this?

The existing MobEffect class in Minecraft is very limited and has only very specific and basic functionality.

You can't really do a whole lot with it without needing extra events, mixins, or any combination or the two.

 

This lib does the work for you, adding several new hooks and features allowing you to make much better use of the effect system

 

Features:

  • Instance-sensitive tick method
  • Instance-sensitive display name
  • Can-apply checks
  • Mutually-exclusive effects check
  • On-application callback
  • On-reapplication callback
  • On-removal callback
  • Instance-sensitive shouldTick method
  • Pre, during, and post attack method callbacks for both incoming and outgoing attacks
  • Client-side tick callback
  • Custom screen overlay render callback
  • Helper classes for building effects and potions
  • Experimental extended Enchantments support

 

How do I use it?

Just about everything you'll need to know is documented here:

https://github.com/Tslat/TslatEffectsLib/wiki

 

To get started, just have your new custom effect extend ExtendedMobEffect instead of MobEffect, then make use of any of the methods available to you
