This is an even more complex scrolling platform example. I was asked to make it multi-direction using Scroll X and Scroll Y, so here you go! The main thing to note is that to make the backgrounds you must name them as a two digit number (the first is the x index, the second is the y index of where the background should be positioned). Can you let me know if this lags now on your PCs? Also, I needed to alter some of the scripts a little to make it work... I might back some of this out or change it around till I find the best way :)
