Wool Elevators, a Datapack for Servers

Wool Elevators

**Stand on a wool block and jump — you rise to the next wool block of the same
colour above you. Sneak — you drop to the next one below. That is the whole
thing.**

No mod. No new block to craft. Nothing for players to install: the server has
the datapack, everyone gets elevators.

Same colour, same shaft

A red shaft and a blue shaft can run side by side in the same wall without ever
mixing up. That also means ordinary stacked wool in a build will not send anyone
flying — the colours have to line up.

Sixteen wool colours, sixteen independent shafts.

| | |
|—|—|
| Jump | Rise to the next block of the same colour above you |
| Sneak | Drop to the next one below |
| Range | Up to 64 blocks per ride, adjustable |
| Blocked? | Two free blocks are needed above the landing, otherwise you stay put and hear a short note |
| Cooldown | A few ticks after each ride, so holding jump does not launch you through the whole tower |

Settings

/scoreboard players set #range el 64    how far one ride may reach, in blocks
/scoreboard players set #cool el 8      ticks of cooldown after a ride

Both survive restarts and /reload.

Installation

Server

1. Put the .zip into <level-name>/datapacks/
2. /reload, or restart the server

Singleplayer

1. Put the .zip into .minecraft/saves/<world>/datapacks/
2. /reload

Works on a world you already play. It changes no world data and no recipes.

Why a datapack and not a mod

Every other elevator for Minecraft is a mod. That means installing it, keeping
it in step with your loader, and — for most of them — every player installing it
too.

This is a datapack:

• Server-side only. Players install nothing and notice nothing except that jumping on wool now takes them somewhere.
• Works on Vanilla, Fabric, NeoForge, Paper, Purpur, Folia — the loader does not matter.
• Nothing is added to the game. No new items, no new recipes, no new blocks. Wool stays wool everywhere else.

Tested, not assumed

Every promise on this page is checked by an automated test on a real server, on
26.1, 26.2 and 26.3:

| Check | |
|—|—|
| Jumping rides up to the next block of the same colour | ✅ |
| Sneaking rides back down | ✅ |
| A different colour in between is skipped | ✅ |
| No matching block, no ride | ✅ |
| Blocked landing, no ride | ✅ |
| Beyond #range, no ride | ✅ |

And with a real player connected, jumping and sneaking really trigger it — not
just the internal functions.

FAQ

Does it work with any wool?
Yes, all sixteen colours. Both ends of a ride must be the same colour.

Will my existing wool builds turn into elevators?
Only if two blocks of the same colour sit in the same vertical line with a free
landing — and then only when someone deliberately jumps or sneaks on one.

Can I use it in singleplayer?
Yes, the same way.

Does it break mob spawning, redstone or anything else?
No. It adds nothing and replaces nothing. It only reacts to jumping and sneaking.
