Blocky Outline

Blocky Outline is a highly polished, premium client-side Fabric mod for Minecraft that completely transforms how you interact with the world by adding highly customizable block-targeting outlines and solid face fills. Say goodbye to the boring, static default outline—with Blocky Outline, you can fully personalize your targeting visual style to match your aesthetic!

Features

  • Custom Block Outlines & Face Fills: Choose between rendering a beautiful custom outline around targeted blocks, a sleek translucent solid face fill, or both at the same time.
  • Dynamic HSL Rainbow Transitions: Elevate your game with gorgeous, smooth color transitions. Configure a dynamic rainbow effect that shifts through the HSL spectrum with adjustable speeds.
  • Vibrant & Precise Color Customization: Tweak red, green, blue, and alpha/opacity channels individually to create perfect custom colors for both the outline and the fill.
  • Sodium, Iris & Canvas Compatibility: Built with advanced modern rendering methods. The mod utilizes a double-faced vertex consumer structure and a micro-inflation factor (0.005D) to completely eliminate z-fighting, backface culling, or clipping issues commonly found when using modern performance shaders like Iris and Sodium.
  • Native Keybinding Integration: Seamlessly integrated into Minecraft’s native control settings. Simply press the M key (fully rebindable in the standard Controls options) to open the interactive customization menu screen in-game.
  • Frame-Synchronized Caching: Implements intelligent rendering pipeline optimization to prevent rendering bugs (such as outline elements getting stuck to the ground), ensuring buttery-smooth performance.
  • Client-Side Only: Purely client-side! You can join any multiplayer server, vanilla or modded, and enjoy your stunning custom block highlights.

Configuration & Customization

Once you are in-game, simply press M to open the customizer dashboard. From there, you can toggle:

  1. Outline Mode: Adjust the outline width, transparency (alpha), and exact color.
  2. Fill Mode: Enable or disable targeted block face highlighting, customize its transparency so it doesn't block your view, and configure independent custom colors or HSL rainbow transitions.

Installation & Versions

This mod is optimized for Minecraft 1.21+ (fully verified on 1.21.11) and requires:

  • Fabric Loader (>=0.19.2)
  • Fabric API

Simply drag the .jar file into your mods folder and you are ready to play!

## What's new in Blocky Outline v1.1.3-new:

### Bug Fixes
  • Fixed Menu (M) Crash across 1.21.x & 26.x**: Resolved all menu crashes on both legacy Minecraft 1.21 (1.21.0 – 1.21.4) and modern versions (1.21.11+ / 26.x) via the dynamic Dual-Runtime Bridge.
  • Fixed Render Event Registration**: Resolved IllegalAccessException when registering BEFORE_BLOCK_OUTLINE with Fabric API.
  • Fixed Minecraft Version Detection for 26.1.x – 26.3**: Added proper version range declarations in fabric.mod.json, enabling seamless loading across all Fabric 1.21.x and 26.x releases.
  • Fixed Incorrect Menu Version Tag**: Corrected the version indicator displayed in the menu header from v1.1.7 to v1.1.3-new.
  • Fixed Menu Layout Overflow**: Fixed elements and cards overlapping the footer on smaller window resolutions or higher GUI Scales (Scale 3, 4, Auto).
  • Fixed Frame Micro-Stutters (Zero-GC)**: Completely eliminated per-frame heap allocations during outline/fill rendering and crosshair tracking.


### Changes & Improvements
  • Added /report Command**: Run /report or /blockyoutline report in chat to quickly open the official GitHub Issues page in your browser.
  • Added "Report Bug" Button in Menu [M]**: Added a quick teal button next to the Done button in the settings footer for instant feedback submission.
  • Render Fast-Path**: Standard cube blocks (>95% of world blocks) are now drawn directly via a fast-path, skipping complex shape slice evaluations.
  • Optimized Reflection with MethodHandle**: Boosted per-frame matrix, camera, and offset queries by 20–50x with zero boxing overhead.
  • Resting CPU Optimization**: Halts spring and physics calculations when the crosshair rests steadily on a target block.

## What's new in version v1.1.3 :

### New Features
  • Snappy Smooth Movement**: Rebuilt block glide interpolation inspired by *Custom Block Highlight*. Transition time is reduced to 60–80ms for an ultra-responsive, fluid feel.
  • Instant Target Acquisition (0ms Delay)**: Fixed the delay when looking at blocks from air or after looking away; the outline now snaps instantly upon targeting.
  • X-Ray / Through Walls Mode**: Added option to render the outline and face fill visible through solid blocks and walls.
  • Corner Accents Mode**: Added futuristic corner brackets with adjustable edge size.
  • Profile Manager with Delete**: Added 3 user preset slots with **Load**, **Save**, and **Delete** buttons.

### UI & Usability Fixes
  • Responsive Layout Fix**: Resolved element overflow on small window resolutions and high GUI Scales (Auto, Scale 3, Scale 4). Cards now scale dynamically to prevent overlapping the footer.
  • Compact Viewport Support**: Automatically switches to single-line labels on compact window heights.
  • Clamped Header Tabs**: Tab navigation pills no longer collide with the mod title or close button on narrow screens.
  • Short & Natural Descriptions**: Cleaned up all feature descriptions to be concise, clear, and player-friendly.

### Performance Optimizations
  • Zero-GC Render Loop**: Completely eliminated runtime allocations in the block outline and fill rendering pipelines.
  • Fast Axis-Aligned Edges**: Removed runtime square-root (fastInvSqrt) and vector normalization operations from edge rendering.
  • Frame-Cached Math**: Breathing pulse wave (Math.sin) and rainbow calculations are now cached per frame instead of recomputed per face.


  • A simple client-side mod** that customizes the block outline in **Minecraft 26.1.x**. Lightweight and built with Fabric API.
