Installation

Installation

Hex is a client-side Fabric mod. You install it into your own Minecraft; nothing goes on a server, and other players do not need it.

Requirements

Requirement	Version
Minecraft	26.1.2
Java	25 or newer
Fabric Loader	0.19.3 or newer
Fabric API	Built for 26.1.2 (0.155.0+26.1.2 or newer)
Fabric Language Kotlin	1.13.13+kotlin.2.4.10 or newer

Mod Menu is optional. With it installed, its settings button on Hex's entry in the mod list opens Hex's config menu. Without it, Hex behaves identically — it is neither bundled nor required.

Steps

1. Install Fabric Loader for Minecraft 26.1.2 with the Fabric installer.
2. Download the dependencies — Fabric API and Fabric Language Kotlin, both for 26.1.2.
3. Download Hex from the releases page. Take the file named hex-<version>.jar; ignore the -sources jar, which is for developers.
4. Drop all three jars into your mods folder.
   • Windows: %APPDATA%\.minecraft\mods
   • macOS: ~/Library/Application Support/minecraft/mods
   • Linux: ~/.minecraft/mods
5. Launch the game with the Fabric profile.

Checking it worked

Join a world or server and run:

/hexa

Hex replies with its version and the list of available subcommands. If the command does not exist, the mod did not load — see Troubleshooting.

You can also open the settings menu without joining anything: from the title screen, press Options and click the small □ button next to Done.

Where Hex keeps its files

Everything lives under config/hex/ in your Minecraft folder — see Config files for what each file holds. Deleting that folder resets Hex to defaults; it never touches anything outside it, apart from Minecraft's own options.txt when you change a control through control switches or the attack mode switch.

Updating and uninstalling

Hex updates itself — see Updating. To uninstall, delete hex-<version>.jar from mods. Your settings stay in config/hex/ unless you delete that too, so reinstalling later picks up where you left off.
