I'm currently writing a game in XNA for fun which uses C#. I have got my sprites loaded and when the character moves right he looks like he is running right and when he moves left he looks like he is running left.

I been looking everywhere for a good coding example for how to create a jumping ability. I have read all the physics stuff that I can stand and it doesn't help when I can't figure out how to use say space bar to jump yet can't keep them from using space just jump again until they land.

I'm a software engineer that's new to game programming so forgive me if this is a dumb question as I don't know that much about game engines.
