Notice: I am currently no longer working on this project for the time being.
tile2d, an improved version of its predecessor kin2d, is a physics engine built specifically around tiles. By employing multiple threads, it speeds up the processing of thousands of Rigid-Tile bodies.
The goal is to super-optimize tile-to-tile collisions, allowing for thousands or even tens of thousands of collisions to happen at a time.
The data which is contained inside of tiles is entirely user-decided because of the use of templates.
See this for documentation.
For now, public documentation is mostly done, but it still needs work in some places.
