Requires HalbLibe => 3.5.4
Specifically made for Minecraft Better Than Adventure 7.1_01.
This new block can be used for lots of different contraptions and builds. The vent block propels entities upwards for a total of 8 blocks.
Sneak while walking above a vent block will result in you falling down again and ignoring fall damage!
Multiplayer is not supported, I might add support in the future.
