About this project

What does AutoRun Key add?

AutoRun is a tiny, client-only Fabric mod that lets you walk and sprint forward without holding any key. Press K once to start moving — your character will walk and sprint until you press K again, press S (backward), or open any screen.

Features

  • One key, two states. Press K to toggle hands-free forward movement on/off.
  • Sprinting included. Auto-sprint is on by default — covers ground fast.
  • Safe defaults. Pressing S (move backward) cancels auto-run instantly, so you never get stuck running off a cliff while you grab a drink. Auto-run also disables itself if you die, mount a vehicle, fall asleep, or open any inventory/menu.
  • Tiny footprint. Only one small KeyboardInput.tick tail hook — other movement mods keep working as expected.
  • Client-only. Works on any server (singleplayer or multiplayer), no server install needed.

How it works

On every client tick, the mod rebuilds the PlayerInput record with forward = true and sprint = true while auto-run is active. The change is invisible to the server — it's the same packet your fingers would send.

Compatibility

Tested on Minecraft 1.21.8, 1.21.9, 1.21.10, and 1.21.11 (Fabric Loader 0.16+). One JAR for all four versions.

Default key

The toggle is bound to K (hard-coded for now). Want a different key or a config screen? Open an issue.
