This is the scratch project I am proud of the most. I actually have worked on this for years and finished it quite a while, but never uploaded in fear of someone else making a 360 degree Sonic game before me using this. It is the first working engine to cover the entire 360 degrees on Scratch using gravity, allowing loops and curves in the terrain to be much more realistic. I might use this to make single Sonic levels as amazing as the ones from Sonic Advance, but my hopes for making a full-length game have faded because of Scratch's size limit. This took years of fidgeting and I finally got a head start by using Kiley's slope detection. However it was was not capable of going every direction and would glitch if a steep slope was attempted, let alone upside down. Kiley did not use sin or cos, the important expressions needed to make a 360 degree engine. Instead I remade the entire engine by teaching myself some trigonometry to make make this. After years of trying, it worked. Now everyone can enjoy this because I finally gave up keeping it to myself. If you need help making something like this, feel free to look at the scripts. But please understand how important this is to me, and give credit for anything you use. If scripts or sprites are copied, not remade in someone's own style, I will be very upset that they didn't even take the time to remake what took me years to figure out. If anything is taken from this without giving credit, you better hope I won't find out about it. The Scratch Team let me know if this happens I can report whoever did this, and their project will probably be removed unless they give credit. Sadly, Scratch is stuck on the point that it is all about learning, so there will never be a way to protect projects. Really, learning is only just the start, and without out a way to share work and protect it, serious programmers will not want to use Scratch for serious programming, even though it is capable for amazing, but small, projects. (When I go back and read this, I do still agree in some ways, but I understand the issues this would cause as well.) There are lots of glitches to fix and tweaks to be made still. I hope you enjoy this guys. -Cheeta
