About this project
What does BetterCosmic add?
BetterCosmic
BetterCosmic is a client-side quality-of-life mod for Cosmic Prisons — customizable HUDs,
inventory overlays, event tracking, and handy tools, all configured from a custom in-game menu.
Everything is optional and independently toggleable.
HUDs
Draggable, scalable, recolorable overlays:
- Cooldowns — timers for commands and abilities
- Satchels — live fill vs. capacity
- Stats — XP, XP/hr, energy, and session totals
- Enchants — active timed enchants like Super Breaker & Powerball
- Events — meteors, ore merchants, meteorite showers, and bandit rushes
Navigation
- Screen-edge waypoints and optional 3D beacon beams for every event
- Gang pings — broadcast your position (or a block you're looking at) to gang chat
Inventory & tooltips
- EasyView — energy, notes, gang points, item levels, and more shown right on items
- Enchant-book upgrade costs and local-time gang-point expiry
- Chest search with filter rules, plus clue-scroll step sorting
Quality of life
- Peaceful mining — ghost nearby players while you mine
- DM sound alerts, pickaxe drop protection, shift-click auto-trade, and more
- Built-in updater — get notified of new versions and auto-install them
Configuration
A fully custom in-game menu (default I, or Mod Menu): collapsible panels, a drag-and-drop HUD
editor, color pickers, and theme customization. No external libraries required.
