Super Jump
by FroggyLoggy
Super Jump lets a player charge a leap while sneaking and launch straight up, a server-side utility for Fabric on 1.21.11.
What it does
Holding sneak for about two seconds charges the jump, and releasing the sneak key while pressing jump sends the player up roughly 6 to 8 blocks in a straight line. The jump is meant to be used from a solid block, and fall damage still applies when the player lands. The launch works on any standing solid surface, so the height gained comes from the charge rather than from potions or gear.
Because the logic runs on the server tick, the mod behaves the same in single-player worlds and multiplayer servers. It hooks into the game's native movement system through a two-step input sequence, so no separate movement key or client code is needed. Fabric Loader and Fabric API must be installed on the server for it to load. Super Jump is released under the MIT License but is not open source, and its only published build targets 1.21.11.
Key features
Charged launch
Sneaking for two seconds charges the jump, which then fires when the jump key is pressed.
High vertical reach
A charged jump propels the player 6 to 8 blocks straight up through open air.
Server-side logic
All movement logic runs on the server tick, so the behavior is identical for every player on a server.
Native movement input
The jump is triggered through the game's standard sneak and jump inputs instead of a new keybinding.
Compatibility
Latest build for each game version and loader.

Use cases
Exploring vertical terrain
Players can reach ledges and cliff tops that a normal jump cannot clear.
Escaping tight spaces
A charged launch can carry a player out of a pit or enclosed area quickly.
Showing off on multiplayer servers
Groups can use the high leap for stunts and displays on a shared server.
Who it’s for: Server owners who want a simple vertical movement option without potions, and players on those servers who explore cliffs and caves.
