About this project
What does Randomizer Ultimate Core add?
Randomizer Ultimate Core is a mod that randomizes the drops of blocks and mobs, with additional optional features for randomized loot and complete chaos.
By default, Randomizer Ultimate Core assigns every block and mob a random item drop. These drops remain consistent within the same world, meaning that if dirt is randomized to drop diamonds, it will continue dropping diamonds in that world. However, every world gets its own unique randomization.
For example, in one world, dirt might drop diamonds, zombies might drop netherite ingots, and stone might drop apples.
Admins or players with cheats enabled can generate a new set of randomized drops at any time using:
/randomize
Chaos Mode
For even more randomness, Chaos Mode makes blocks and mobs drop a different random item every single time.
You can toggle Chaos Mode using:
/randomizerultimatecore chaosmode true/false
This command requires operator permissions or cheats to be enabled.
Randomized Loot
Randomizer Ultimate Core can also randomize the loot found in naturally generated loot containers, such as chests.
This feature can be enabled or disabled using:
/randomizerultimatecore randomizeloot true/false
Like the other commands, this requires operator permissions or cheats.
Note: Incompatible with Lootr
