How do I implement a vertical parallaxing image?

I have an idea for an old-school arcade top-down shooter similar to 1942. I am simply trying to figure out how to make a background image scroll vertically underneath the fighter jet as it fights off enemy aircraft. Can you help?

Thanks

Mike

There is an amazing example on the Example Browser called Glokar for this type of game done by MATTHEW GRUBER Tokinsom and HENRIQUE LAZARINI 7Soul that should cover all your questions :)

It´s really well commented and helps a lot learning and understanding C3 (At least it did for me) :)

Thank you very much for taking the time to reply. I was starting to think nobody knew how to do it lol. The closest example I could find on the Example page was a game called Channel Shooter (or something along those lines?) It was written entirely in Javascript, so that didn't help me. It's good to see I was thinking along the right lines.

Btw, for anyone else wanting to look at the file. The game didn't come up in the Example page search for me. I had to Google it.
