Doublejump
by SQRT256_
Doublejump gives players a second jump in mid-air, triggered by pressing the jump key again while falling or rising.
What it does
Pressing jump a second time while airborne launches the player upward with a burst of cloud particles. The jump is built into vanilla-friendly mechanics and is meant for worlds that keep the game's standard controls. Each extra jump costs three hunger bars, and a ten-second cooldown is shown live on the action bar so players can see when the next jump is available. The launch follows the direction the player is looking, and the power can be set separately for horizontal and vertical motion in the config.
The sound of the jump changes with the boots a player wears, with a distinct effect for leather, chainmail, iron, gold, diamond and netherite. Doublejump runs on client and server, so the server and every player need it. It requires Fabric API and is published for Fabric only, across three release versions, 26.1, 26.1.1 and 26.1.2, under a Creative Commons Attribution 4.0 license. The code is not open source.
Key features
Mid-air second jump
Pressing the jump key again in the air triggers an extra upward launch without any item or command.
Hunger cost and cooldown
Each jump uses three hunger bars, and a ten-second cooldown appears on the action bar until the next jump is ready.
Look-based momentum
The launch carries the player in the direction they face, so jumps can be aimed across a gap or upward.
Boot-based jump sounds
The jump sound varies with the boot material, from leather through to netherite.
Adjustable launch power
Horizontal and vertical launch strength can be tuned separately in the configuration file.

Use cases
Parkour and traversal
Players crossing wide gaps or climbing tall structures can reach ledges that a single jump cannot clear.
Adventure maps
Map makers can use the extra jump to shape routes and puzzles around vertical movement.
Who it’s for: Players who want more vertical reach in survival or adventure play, and server owners who want to tune how far the extra jump carries.
