Vertical Navigator

Vertical Navigator shows exactly what's below — before you jump.

How it works

Sneak near any edge and a ray traces straight down. A glowing marker lights up the landing point, while your HUD shows drop height and predicted fall damage in hearts. Water, lava, fire, and void all get color-coded warnings so you know what's waiting.

Features

• Edge detection — triggers when you sneak, no block directly below needed (3×3 area scan catches platform edges)
• Fall damage preview — hearts show (height − 3) × 0.5 formula
• Water buffer — landing in water cancels damage, blue marker
• Lava · Fire · Void — instant death warnings in red / orange / purple
• Configurable HUD — press V to open the config screen, use arrow keys to position and scroll wheel to resize, with live preview
• Bilingual EN/CN — auto-switches with your Minecraft language
• Client only — no server install needed, works on any multiplayer
