Different values for applyLinearImpulse when tilted?

So I am working on this app similar to the balloon game example. I have added function for the accelerometer and tilt in my version. I am looking for a way to change the value of the linearimpulse so that when I tilt 180 degrees and tap the bottom of my object it will go towards the “new top” of the screen. Same if it is tilted into landscape.

You dont have to give me the exact code, if you could just point me to a section of the API reference that would get this done that would be great.

Other than that I have everything working! Thanks guys. [import]uid: 20431 topic_id: 5208 reply_id: 305208[/import]
