How do I use a sin curve to make rising and falling smoother?

Bellatorius

Hi guys,
I'm pretty new to gamesalad and am making a jetpack joyride style game. Here's an example of what I have so far: http://rocketmangame.blogspot.ie/2013/02/proof-of-concept-video-2.html

The problem is trying to implement a sin curve to make him more realistically rise and fall when the screen is touched and released.
Currently, I have it very linearly set up using acceleration.

Thanks for any help you can give me!

Try this demo I quickly made up. Just using accelerate - but it has a smoothness to it. You can add to the upwards acceleration - hope it helps.

Take a look at this template by DBA - They have a pretty nice setup - http://www.deepblueapps.com/jetpack-template/

That does look awesome, alas the game is for a masters project, and I don't think they would take too kindly to buying a template!

That one is much smoother alright! Is that because of the constant downward force?

Thanks,

Yep. :-) Hope it helps. Good luck with your project!
