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!
