Plugin API/Tweaks collection on top of an Orion Mixin loader & Paper Minecraft server software

• Various item tweaks:
  • Exposed canPlaceOn and canDestroy NBT tags
• Player tweaks:
  • Built-in AFK events
  • Can disable player data saving - extremely useful for most lobby servers
  • Disable idle timeout kicking for opped players (Vanilla does not have that feature built-in for some reason!)
• World system tweaks:
  • More precise spawnpoint without plugins! Decimals and yaw/pitch are saved to world directly now¹
  • Disable UUID conversion on every goddamn server start. Saves start up time if worlds don't need to be converted from older server versions
  • Override default gamerule values (by default "announceAdvancements" is set to false by Helios) using config
• Command system tweaks:
  • Makes default permission denied message configurable (The famous red I'm sorry, but you do not have permission to perform this command... message)
  • Also can make override every² plugin permission message (Your server can now have consistent permission messages!)
• Server core tweaks:
  • Automatic EULA agreement. As you should agree to EULA anyway if you are going to run a Minecraft Server
  • Query protocol plugins list response modification (to disallow exposing installed plugins to prying eyes)
• Various exploit precautionary tweaks:
  • Strict check for item name length on Creative gamemode
  • Disable using NBT received from Creative gamemode³
  • Disable copying container blocks
  • Validate player's locale string

¹ - Not supported outside of Helios
² - Depends how plugin was made.
³ - Might cause confusion, option below is bit better choice

• Orion
• Paper 1.12.2
• Java 8

1. Build Paper server from source, install server (yes, server, not API) jar to local Maven repository
2. Clone this repository and invoke ./gradlew build
3. Grab jar from build/libs and put it to mods/ directory of your server
4. Start server once and configure the Helios
5. Enjoy :)
