Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Parkour Helper

`/parkour`

Configures various settings related to parkour. Syntax is identical to /gamerule.

`sprint_leniency (true)`

Whether or not hitting surfaces softly breaks sprint. Good for disabling in onlysprint maps.

`allow_swimming (true)`

Whether or not players can 1.13 swim. Disabling also enables sprinting when touching water

`sneaking_player_height (1.5)`

Self-explanatory

`movement_snap_threshold (0.003)`

if (Math.abs(yPosition) < movement_snap_threshold) {yPosition = 0.0d;}

`allow_sprint_sneak (true)`

Whether players can keep sprinting when they begin sneaking

Functions

There are also three functions (accessible via /function) that act as presets for compatibility with 1.8 and 1.12 maps, as well as one that resets everything to default (current version).

Happy parkouring!
