Hello, @erincatto
The
box2d-liteis a very useful project for beginners. I am reading the source of this project, and try to figure out how it works.I have read the publication
How Do Physics Engines Work?andFast and Simple Physics using Sequential Impulses.It looks like the
Contact.Pnbfiled is un-used in the source, and is not mentioned in the publications.So will it better to remove this field, for clearity?
