Hello,
I got my students to understand why we need to put the “background” code in the loop, by explaining how the loop works with a counter pattern and showing the difference when a sprite moves with the background in and out of the loop.
However using a sprite as the background, we do not put that in the loop, and it works fine without the duplicate image streak that happens when the “background” code is not in there. can someone clarify the difference between them and why it does not happen with the sprite background.
thanks!
