Hello again! I've got another one command creation for you guys. In this one there are jetpacks. Now, I know there are a ton of commands for jetpacks, but I was just messing around with the levitation effect in 1.9. This project is the results of those experiments.

Crafting:
Throw 1 furnace, 1 iron chestplate and 4 blaze powder on the same block to craft a jetpack.

Usage:
First, you might want to get some fuel. Fuel for the jetpack is charcoal and coal. When you've got coal or charcoal in your inventory as well as the jetpack equipped in the chestplate armor slot, you'll notice the coal/charcoal begin to deplete. One coal/charcoal is used every 20 seconds.

Controlling:
When you have the fuel and jetpack equipped, you need to jump. This will activate your jetpack and you'll be brought up with a message. There are 3 options; [Up] [Hover] [Down]. Click on the messages in the chat to activate that control. The controls activate continuously when clicked. They are pretty self-explanatory, but up increases your height. Down drops you(Beware! This completely shuts off the jetpack and you will fall. Fall damage is negated, but watch out where you land). Hover keeps you stationary at an altitude.

Requirements:
Minecraft 1.9+

Command:
