My first project is a scrolling shooter. I have 10 levels of parallax scrolling, which is overkill, I was just testing the performance. It's no harder to do than in DB Pro. Just odd to use sprites, rather than image commands for the backdrop.
The technique works, as I have a demo (work in progress) running using it. Although I confess to not reading the examples, and diving straight in myself. I have made my scroll loopable, which has presented more problems than I anticipated, although I knew having a looping level would make things a little more difficult.
My only gripe with it is the odd glitch, which shouldn't be there, in the scroll. I have since loaded the elf demo and noticed it in that too. Although the scroll is perfect, it occasionally jitters. I wonder why, although this is not a new thing for me. Many languages have had this issue, AMOS, DB, DB Pro, and now AppGameKit have all had this untreatable glitch with scrolls.
But I am waffling, my scroll involves 2 sprites. I change the images as I move along them. So I start on sprite 1, and when I get to sprite 2, I change the images and move back to sprite 1. As long as you shuffle the images correctly you have a scroll.
