Crystal per Second HUD

A modern Fabric mod that displays End Crystals destroyed per second (CPS) as an in-game HUD overlay, with full multi-version support via Stonecutter.

Editor Keybind: H

Use Cases

• Crystal PvP Practice: Track your real-time crystal destruction speed while training
• Performance Benchmarking: Compare CPS output across different crystal optimizer mods

Features

CPS Tracker

Tracks End Crystal destructions in real-time and displays them directly on your screen:

• Instant Mode: Reactive calculation, averaged over the last 3 intervals
• Smoothed Mode: Window-based calculation, counted over a rolling 1-second window
• Live Updates: HUD value updates continuously as you play, no manual refresh needed

Editable HUD

Full in-game control over how the HUD looks and where it sits:

• Drag & Resize: Reposition and resize the HUD directly in the editor screen
• Editor Popup: Quick-access gear icon (⚛) for toggling display options

Display Customization

Fine-tune the HUD to fit your setup:

• Background: Toggle the dark background box
• Borders: Toggle the white border around the HUD
• Text Shadow: Toggle text shadow rendering
• "CPS" Label: Show or hide the "CPS" label suffix
• Green When Active: Color the text green whenever CPS > 0
• Smooth CPS: Switch between instant and window-based calculation

Crystal Optimizer Compatibility

Counts crystal destructions via Player.attack(), so it works correctly alongside most crystal optimizer mods:

• Marlow's Crystal Optimizer
• Walksy Crystal Optimizer
• CrystalAccelerator
• G1ax Tweak Mode

Known limitation: G1ax Crystal Optimizer (Default Mode) bypasses vanilla attack paths and may result in lower CPS readings.
