All the datapacks features:

• 
  Have coal in your inventory and sneak to move upwards
  
• The Jetpack will beep when your fuel level is below five.
• You can have the coal at any place in your inventory.
• you can spare fuel by not always pressing on shift and only pressing it every second or so.
• you can change the fuel usage (look below the crafting)

Craft (drop the items on the ground):

The Jetpack is using too much fuel, how can i change that?

By default the fuel usage is a 1 per second, to modify it, first unzip the datapack inside the datapacks folder, it should look like that:


if you have a folder called data and a file called pack, move them inside of a new folder, onece it is done, remove the zip file of the datapack. now go to: jetpacks/data/jetpacks/functions and open tick.mcfunction as a text file, now change:

scoreboard players set @a fueltimeout 20and replace the 20 with any value in ticks you want, note that 1 second is 20 ticks, in this example it will use 1 fuel per second.



Enjoy your jetpack!
