About this project

What does TheRuler add?

Ruler

**Ruler** is a lightweight, client-side selection and measurement tool for Minecraft 1.21.1 (Fabric). It lets you mark two positions in the world and instantly see a clean holographic 3D visualization of the selected area — along with all relevant measurements in a HUD overlay.

Inspired by WorldEdit CUI, but completely standalone. No server plugin or WorldEdit installation required.


How it works

Press **R** to activate the ruler (rebindable under Controls → Ruler).

  • **Left-click** a block to set **Pos1**
  • **Right-click** a block to set **Pos2**

That's it. The selection renders immediately.

Press **R** again to deactivate and clear the selection.


3D Visualization

The selection is rendered as a holographic wireframe box directly in the world:

  • **XYZ color-coded edges** — X red, Y green, Z blue
  • **Subtle inner grid** for spatial orientation
  • **Transparent block highlights** at Pos1 (green) and Pos2 (red)
  • Single positions are shown before the second is placed
  • Clean, modern look — no chunky vanilla-style boxes

HUD Overlay

A small panel in the top-left corner shows:

Field Description
Pos1 / Pos2 Block coordinates
Distance Direct 3D diagonal (air-line)
X / Y / Z Dimensions of the selection
Area Footprint (X × Z)
Volume Total blocks (X × Y × Z)

Languages

Ruler ships with **37 languages** out of the box:

**Standard:** English, Deutsch, Français, Español, Italiano, Português, Русский, Українська, Polski, Nederlands, Svenska, Dansk, Norsk, Suomi, Čeština, Slovenčina, Magyar, Română, Türkçe, Ελληνικά, 简体中文, 繁體中文, 日本語, 한국어, العربية, עברית, Tiếng Việt, ภาษาไทย


Compatibility

  • ✅ **Client-side only** — works on any server, no server mod needed
  • ✅ **ModMenu** — appears correctly in the mod list
  • ✅ Fabric API required

Requirements

  • Minecraft **1.21.1**
  • Fabric Loader **≥ 0.17.3**
  • Fabric API
