Magma Bubble Column Backport
OUTDATED
THIS MOD IS NOW INCLUDED IN:
https://www.curseforge.com/minecraft/mc-mods/bubble-column-elevator-backport
This mod recreates the functionality of the bubble elevator that was added in Minecraft version 1.13.
The mod completely replicates the behavior of the standard bubble elevator from vanilla Minecraft - the movement speed and player movement mechanics are identical to the original, since the code was taken directly from Minecraft's source code.
The system works with all types of entities, including dropped items and mobs.
Here's a small demonstration of the mod in action:

The mod replaces the standard magma block with a modified version that creates bubble columns. Don't worry - visually the block remains the same magma block you're familiar with.
