📉 Fall Damage Predictor

Ever looked down a cliff and wondered, "Will this jump kill me or just hurt?" Stop guessing. Fall Damage Predictor is a lightweight, client-side Fabric mod that predicts your survival chances in real-time by highlighting the blocks you're about to land on.

🚀 Key Features

Dynamic Calculations: It’s not just about height. The mod accurately calculates damage based on block properties. Hay Bales, Beds, Honey Blocks, and Pointed Dripstone are all accounted for using vanilla 1.21.1 physics.

  • Visual Safety Zones:

  1. 🟩 Green: 100% Safe. Zero damage landing.

  2. 🟨 Yellow: You'll take damage, but you'll walk away.

  3. 🟧 Orange: Critical! You might accidentally survive, but better not jump.

  4. 🟥 Red: 100% Lethal. This jump will send you straight back to your bed.

🧠Smart Filtering:

  • Automatically ignores water and slime blocks—if there's no indicator, you're good to go!

  • Performance Focused: Uses smart block caching to ensure your FPS stays high even while sprinting through complex terrain.

⚙️ In-Game Configuration

Customize your experience on the fly! The mod features a built-in settings menu where you can:

  • MENU OPENS TO MINUS ("-")
  • Toggle Mod: Enable or disable the predictor with a single click.
  • Scan Radius: Adjust the detection range to fit your PC's performance.
  • Only Lethal Mode: Minimalist view-only shows red markers when a jump is deadly.
  • Show Green: Toggle indicators for safe landings (0 damage).

🛠 Technical Specs

  • Built for Fabric 1.21.1 with precision in mind.

  • Side: 100% Client-side (No server-side install required).
