About this Mod
Meka-PMMO
A compatibility bridge between Mekanism and Project MMO (PMMO) that enables XP rewards from Mekanism machines.
Overview
Meka-PMMO provides seamless integration between Mekanism's machines and PMMO's skill system. Players now earn XP when using Mekanism's Energized Smelter, just as they would with vanilla furnaces. Latest updates also include Block Break XP and Restrictions Enforcement on the Digital Miner!
Dependencies
| Mod | Version | Required |
|---|---|---|
| Minecraft | 1.20.1 | ✅ |
| Forge | 47.4.0+ | ✅ |
| Mekanism | 10.4.16.80+ | ✅ |
| PMMO | 1.20.1-1.7.39+ | ✅ |
WARNING
This mod is really only valid for early-mid game Mekanism, once you start getting towards end-game with large factories of multiple smelters each with multiple speed boosts this COULD cause performance issues as it tries to fire an event for every smelt. I may look into some form of caching mechanism in future but for now, this warning is here!
It is generally assumed that by late-game you won't need the XP as much and this bridge would be safe to remove mid-world.
