Random Jump Height
by JokeBanana1
Random Jump Height changes how far the player character jumps, drawing each jump height at random within a fixed span.
What it does
Each jump goes to a height picked at random between 0.4 and 4.4 blocks, so the same key press can end a short hop or a long leap. The mod is built for experimental play rather than normal progression, and it is useful in parkour and survival challenge runs where adapting to uncertain jumps matters. Standard parkour routes may not work, since a jump cannot be planned on a fixed distance.
The mod is server-side only: just the server needs it, and players join without installing anything. It is published for NeoForge only, across 11 release versions 1.21.1 – 1.21.11, with 1.0.0 for 1.21.11 as the latest file. It is released under All rights reserved and is not open source.

What the author says
This makes gameplay unpredictable and chaotic, turning even simple movement into a fun challenge. It’s especially interesting for parkour, survival, or challenge runs where precision and adaptation matter. Before downloading, keep in mind that movement will no longer be consistent — every jump is random, so standard…
