About this project
What does Simple Block Randomizer add?
Block Randomizer
Building a stone wall out of four different variants usually means scrolling your
hotbar between every single click. Block Randomizer does the scrolling for you:
enable the slots you want to build with, and every placement picks one of them at
random.
Client-side only. Works on any server, no server install needed.

Features
- Random block placement - every placement uses a uniformly random enabled
hotbar slot. Truly random, so the same block can come up twice in a row. - Pick your slots visually - a settings screen shows your live hotbar as nine
cells. Click a cell to enable or disable that slot - Enable all / Disable all buttons for quick setup.
- Toggle on the fly with a single key, without opening any menu.
- Mod Menu support - open the settings straight from the mod list. The screen
also shows your current keybinds, so there is no need to hunt through Controls. - HUD indicator - a small marker in the top-left shows the mode is
on and how many slots are in the pool. - Settings persist across restarts.
- No server install. It only changes which slot you have selected before a
completely normal vanilla placement.
How to use
- Put the blocks you want to mix into your hotbar.
- Press N to open the settings screen.
- Click the slots that should take part. Green = enabled, red = disabled.
- Press R (or the button on the screen) to turn Random Build Mode on.
- Build. Every click places a random one of your enabled slots.

Default keybinds
| Key | Action |
|---|---|
N |
Open the randomizer settings screen |
R |
Toggle Random Build Mode on / off |
Both are rebindable under Options → Controls → Block Randomizer.
Requirements
- Fabric Loader 0.19.3 or newer
Multiplayer
Safe on servers. The mod only swaps your own selected hotbar slot right before a
normal vanilla placement - it never places blocks you do not have, and it does not
bypass any placement rules. No server-side installation.
