Prebuilt jar

Go to releases, download the latest jar
If you wish to have a prebuilt BETA jar with the latest code, click Actions at the top of the page, click the latest build, and download the artifact

Building from source

Run mvn package

Servers using AEF:

Hisparquia.org (50-150), constantiam.net (70-80), 5b5t.org (50-150), 8b8t.xyz (50-100), 10b10t.org (5-20), 1b1t.tk ( 5-15)

Commands

These commands are only able to be executed by console or opped players.

• /aef ver - Plugin version.
• /aef reload - Reload the config
• /aef kickphrase (phrase) - Kick all players that have said these words. Currently broken will fix when feel like it.
• /aef geared - See how many players have armor or are new.
• /aef elytra - See who is flying on an elytra.
• /aef lag - artificially lag the server for testing. Every time you run the command the server freezes for 1 second

Optimization Guide

You can find an optimization guide at the file GUIDE.md

Missing features

• My modified version of John's god mode patch - Was removed because the original code was so shit that when reloaded with plugman all the players will get kicked, aswell as breaking support for anything other than 1.12.2. Please use my standalone plugin for this (1.12.2 only): https://github.com/moom0o/AntiGodMode. I have another god mode patch but I'm not sure if it works.

Probably won't be added

• Auto-updater, because you shouldn't trust me and instead read the code yourself.
