Hi Everyone,
I am a Designer and i thought i try myself out designing apps.
I want to make a storytelling app for kids for iPad and iPhone.
i would need a little help in how to make simple virtual buttons which i can put on the scenes to make sounds ( like cow, sheep, etc. )
Tried a lot of setups but they just don't work properly

I would need 2 kind of button behaviors :
- a simple button behavior which i can attach to a player that just simply plays a sound and if pushed again it stops
- second button would be a button that plays even if the phone is "sleeping" i would need this to add musics to help kids sleep better
Would really appreciate help

Thanks
Senoy
