Unit 6: Scrolling Background in App Lab

My class is working on unit 6 for circuits.

This student is trying to make his background image scrollable. We can do it in in Game Lab, but it is to working in App Lab.

Any advice?

Hi @jcharpentier,

I like the idea to scroll the road! I see you have figured out that App Lab doesn’t have a continuous loop like the draw loop in GameLab so you have to code one. You were on the right track (:wink:) with the timed loop and highwayy. You do need to “get” the y value of the highway image and then set that to your variable in the continuous loop. I don’t have a working circuit board with me so I setup a basic AppLab looping image here. Hopefully, this will help you figure out how to work the looping highway into your code.

Good luck!
