Have you wished to fly? Do i have the tool for you...

The controls:

Left clicking an un-activated jetpack (you can see with the red lighgt on the texture) will activate it.
Left clicking an activated jetpack (the light becomes green) will de-activate it

When a jetpack is activated:
If you press jump:
- jetpack applies upwards velocity to you
- jetpack wears down a bit
- you become 2x faster
If you press both jump and shift or aux1:
- jetpack applies half as much upwards velocity as when you jump
- jetpack wears down 2x less
- you still become 2x faster

The mode you are flying in can also be seen by how many particles are getting spawned.
The wear is setup such that it lasts you 3 minutes of constant flying

You can re-fuel your jetpack by clicking on a battery, full repair costs 1000 Cj

Jetpack gets de-activated when you move it in your inventory during flight, or when it runs out of charge.

The Jetpack originally used to get automatically de-activated when you stop having it in your hand, but that is no longer the case.

If you "place" it on a battery (sneak+right click), it will take power from the battery and charge the drill! (Just like the jetpack)

In the center of a planet, there is a core, around it is some molten metal.

Molten metal reacts with cold nodes (like water and ice), very slowly, to:

- if a flowing metal source collides with water, it gets turned into the node that the flowing metal was. For example molten silicon => silicon block
