PolySprint

Modrinth downloads CurseForge downloads

PolySprint is a toggle sprint and toggle sneak mod, with a HUD that tells you which state you're in.

  • Toggle sprint and sneak with a single press, and keep the toggle after a restart
  • Bind separate toggle keys, so the normal keys still work for holding
  • Turn off double-tap W sprinting
  • Stop sneaking automatically when you start flying
  • "Fly Boost" speeds up creative flight while you hold sprint (singleplayer only)
  • On modern versions, the toggles stay in sync with the Sprint and Sneak options in Minecraft's Controls menu

Settings

HUD

The HUD shows a line like [Sprinting (toggled)], and tells you whether you are holding the key, toggled it, or the game started it for you. It covers flying and riding too. Every text can be changed, and you move and scale it in the OneConfig HUD editor.
