All of the figure skating on TV lately from the Winter Olympics has me really excited about Newton's Third Law of Motion and the conservation of angular momentum.

It's not an overly exciting part, so to show off the new, telescoping piston in SimpleRockets 2, I threw together a silly satellite that's orbiting an Earth-like planet. It has four very heavy fuel tanks connected by a series of pistons. I got the satellite spinning with some RCS blasts and then I extended the fuel tanks to slow the rotation down. Retracting the fuel tanks increases the rotation speed, just like those figure skaters do with their meaty appendages.

To be honest, it wasn't as exciting as I hoped it would be, but I had too much time invested in this post to abandon it. Maybe I needed some heavier fuel tanks or maybe some better ice skates.

The piston can be customized in several ways in the designer. It's range, speed, and scale can all be customized. It can also be set to cycle back and forth, respond to an activation group, and it can be wired up to any available input. It's a lot of fun to experiment with. Here are the current part details:

  • Mass: 5kg to 212kg (11lbs to 467lbs)
  • Price: $5k to $25k
  • Retracted Size: 0.25m to 1.25m (0.8ft to 4.1ft)
  • Extension: 0.05m to 3.3m (0.2ft to 10.8ft)

    The angular momentum works

    How can I make it so pistons/rotators extend when the part is activated, and retract when they are turned off?
    I want to map the input to its activation state.
    Thanks

    Why do my pistons start out extended? I can adjust them with slider, but they wont start compact and then extend when I want them to

    This game looks really exciting. But I have 1 question... will there be really big awesome explosions?

    @AndrewGarrison, what did you hoped for, if this isn't exciting for you? Many developers can't create this, but you made it! Come on, it will success. motivation mode off

    @MineGamer231 you'll survive, SP had no armament for a long time
    @Diver moar success = moar moneeh, i imagine if you do sciency stuff it'll make money
