RulerMod

# 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** - (https://modrinth.com/mod/fabric-api)
