What it does
Auto Sprint Fix is a small Fabric mod by Amelia. It has one job. What you get keeps your toggle sprint, and your shift, from being reset when you respawn.
The project says it essentially adds MC-263293 back. That's the only reference it gives for how the change relates to the game's own issue tracking, so this page won't guess beyond it.
Say you die, come back, and find yourself walking when you expected to sprint. That's the situation the mod is aimed at. With it installed, the state you had set before respawning is the thing it protects.
Who it suits
It fits players who run toggle sprint or toggle shift instead of holding the keys. Look, if that's you, a reset on respawn is the exact annoyance this targets.
It also suits people who want one fix and nothing more. The project lists a single category, Game Mechanics, and the description covers a single behavior. No extra options, menus or other tweaks are claimed anywhere in the source, so none are described here.
Main capabilities
- Keeps toggle sprint from being reset on respawn.
- Keeps shift from being reset on respawn.
- Brings back the behavior tracked as MC-263293.
That's the whole verified feature list. The source doesn't mention settings, commands or configuration files, so you won't find any described here.
Compatibility
The mod runs on Fabric. No other loader is listed. Don't assume Forge or NeoForge will work, because the source doesn't say so.
The supported Minecraft versions are 26.3, 26.2, 26.1.2, 26.1.1, 26.1, 1.21.11, 1.21.10, 1.21.9 and 1.21.8. That's a specific list, not a continuous range. A version that isn't named isn't covered, so check your exact version and not just the family it belongs to.
It's a client side mod, and the client side is required. Server side is listed as unsupported. You'd install it on your own game. Putting it on a server isn't something this page can recommend.
License
The mod is released under the GNU General Public License v3.0 or later.
Before you install
Check two things. Your game needs to be on Fabric, and your Minecraft version needs to be on the list above. The source gives no dependency list, no install steps and no performance numbers, so none are offered here. If your setup matches, the mod does its single job and that's about all there's to say.
