PolySprint (Toggle Sprint / Sneak)
by Polyfrost
With PolySprint, pressing the sprint or sneak key once keeps that state on until it is pressed again, and a HUD line shows which state is active.
What it does
Toggle sprint and toggle sneak are the core of the mod. A single press starts the state and a second press ends it, and the toggle is kept after a restart. Separate toggle keys can be bound, leaving the regular keys free for holding. Double-tap W sprinting can be turned off, and sneaking stops on its own when flight begins.
The HUD prints lines such as [Sprinting (toggled)] and reports whether the key is held, toggled, or started by the game, including while flying or riding. Every text can be changed, and the position and scale are set in the OneConfig HUD editor. Settings open with /polysprint. The mod runs on the client only, and needs OneConfig and Fabric Language Kotlin, with Fabric API added on the Fabric builds. OneConfig is bundled inside the mod.
The mod is released under the GNU Affero General Public License v3.0 only and is open source. Files are published for Fabric, Forge and Ornithe across 13 release versions, 1.8.9 – 26.3, with 1.8.9 on Ornithe, 1.12.2 on Forge and 26.3 on Fabric as the latest builds.
Key features
Single-press toggles
One press starts sprinting or sneaking, and the state stays on until the same key is pressed again.
Separate toggle keys
Toggle keys can be bound apart from the normal sprint and sneak keys, so holding still works.
Double-tap W control
Double-tap W sprinting can be switched off, leaving only the toggle or the held key to start a sprint.
Fly Boost
While flying in creative mode, holding sprint increases flight speed. This works in singleplayer only.
Status HUD
A line such as [Sprinting (toggled)] shows the current state and whether the game started it.
