RTN's Economy Library
by RTN_project
RTN's Economy Library is a NeoForge library that gives servers a shared money system, with mob rewards, kill combos and encrypted balance storage built in.
What it does
Server owners install the library so that players earn currency from defeating mobs. Passive, hostile and boss mobs each have a default price, and the config file lets a server set an exact price for any entity, including modded ones, through entityOverrides. Boss detection runs automatically, so a modded mob with high max health is counted as a boss and paid accordingly.
Killing mobs in quick succession raises income through a combo. After the first kill a five-second timer starts, and each further kill within it grows the combo, multiplying the payout by up to three. A miss window resets the combo. The current combo and income appear in the action bar in real time. Balances are encrypted on disk and saved periodically in the background with atomic writes and an automatic backup.
The library runs on the server and on the client, and both sides install it. It is licensed under the Apache License 2.0 and is not open source. Files are published for NeoForge only, for game versions 1.21.1, 26.2 and 26.3, with 1.4.0 for 26.3 as the latest file.
Key features
Mob rewards
Killing passive, hostile and boss mobs pays currency, with defaults for each group that a server can change.
Kill combo multiplier
Quick successive kills within the timer window raise income up to x3, and a miss resets the combo.
Entity price overrides
Each entity can be given an exact price in config, and bossEntities forces modded entities to count as bosses.
Encrypted balances
Balances are saved with AES-256-GCM encryption, with atomic writes and automatic backups.
Developer events API
An events API lets other mods hook into the economy bus, and a Vault-style API is available for compileOnly use.
