Tilt your iPhone to land your shuttle safely on a platform on the moon.Install Now!
Control your shuttle using the accelerometer. Tilt your iPhone up and down to control thrust and speed. Tilt your phone left and right to control angle and position. You have to slowly land your shuttle upright on the platform. If you run out of fuel, gravity will not be your friend. Tap the screen to start a new game.
This game is nearly impossible to win. It took me about 25 tries before I landed successfully, and I think I just got lucky. If your life is filled with too much success and pleasure, try this game.
This application was provided as sample code for iPhone developers. Somebody far more talented than me made this application and I take absolutely no credit for it. I just think it's cool enough that it should be distributed for free.
The code license states that developers may "modify and redistribute the Apple Software, with or without modifications, in source and/or binary forms". I'm distributing it unmodified for the world to enjoy.
Sometimes the accelerometer stops working and you can't control the shuttle. Just quit and relaunch the app.How is the score determined?
Your score is based on your velocity, fuel level, rotation, and distance from the middle of the landing base at the time you land. You'll get more points if you have more fuel left when you land, you'll get more points the less your lander is rotated, you'll get more points the closer you are to the middle of the landing base, and you'll get more points the slower you are moving downward at the time you land.
Here's the actual formula (but don't worry too much about it, it's a little complicated):
score = kScoreVelocity * (1.0 - _velocity.y / -kMaxVelocity) + kScoreFuel * (_fuel / kInitialFuel) + kScoreRotation * (1.0 - _rotation / kMaxRotation) + kScoreDistance * (1.0 - fabsf(_position.x - _basePosition) / maxDistance);
kScoreVelocity = 4000
kScoreFuel = 2500
kScoreRotation = 2000
kScoreDistance = 1500
kMaxVelocity = 75
kMaxRotation = 8
kInitialFuel = 4
