Random Item Jump
by mazwey
Random Item Jump gives a random item to a player each time they jump, on Fabric for 1.21.4.
What it does
Each jump triggers a random item to be handed to the player, so the drop is chosen at random rather than set by a fixed table. The mod is a server-side only addition that runs on Fabric for 1.21.4, and it needs Fabric API to load. Players connecting to a server running it do not need to install anything.
The mod is published by mazwey under All rights reserved, so its code is not open source. Files were first published and last updated on 2026-05-08, with 1.0.4 for 1.21.4 as the latest Fabric file. Only the 1.21.4 game version is covered.
Key features
Random item on jump
Every jump gives the player an item picked at random, with no command needed to trigger it.
Command and repeating blocks
Command blocks, chain command blocks and repeating command blocks are part of the set of vanilla tools the mod is built around.
Structure block support
Structure blocks and structure voids are covered by the mod's feature list, alongside the debug stick.
Debug stick access
The debug stick is among the listed items, giving server operators a familiar tool for testing block states.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Server events
Server owners can add a light random reward to a jump-based game mode, with the drop decided on each jump.
Testing builds
Operators working with command blocks and structure blocks can use the debug stick and related tools on the same server.
Who it’s for: Server owners who want jump-triggered random items on a Fabric server running 1.21.4, and operators who build with command blocks and structure blocks.
How it compares
Random Smelting is a Fabric mod for 1.21.1 that runs on client and server, and it is not open source under All rights reserved. Sprint jump nerf is also Fabric for 1.21.1 and client and server, but it is open source under the MIT License. Jump Reset Mod is Fabric for 1.21.11, client-side only, and not open source. Random Item Jump, by contrast, is server-side only and covers only 1.21.4.
