Core began development in mid-2019 with the initial aim of correcting Sonic Worlds' inaccuracies and revamping it to the Sonic Mania style. But from the 0.23.0 version we decided to rewrite everything from scratch to make use of the contemporary Fusion features.

We rewrote the same methods as Sonic Worlds in some situations, but with a ton of changes like the improvements to the collision system, sensors, angle detection, visual angle calculation, landing, ceiling landing and physics.

We rewrote a ton of gimmicks and features from Delta into a brand new code, just like every action, rings, monitors, spikes, platforms, bridges, etc. Some things that naturally worked great were adapted from Sonic Worlds Delta, like water tunnels, screw, corkscrew with slight edits, but everything else was written by us.

We can say that versions before 0.23.0 were modifications of Worlds, while versions after that are a fully rewrite.

Note: This project is no longer receiving any kind of updates from my end. While anyone who wants to update the framework can do so, it will officially happen at the hands of joshyflip, Chopp and Dark. It was almost 4 years of inexhaustible hard work, which I currently have no interest in finishing. There are some bugs with the semi-solids, but Dark is in charge of fixing them. I hope this framework will be useful to you.
