Translating Car On Terrain project from into Processing

Today Simon spent hours translating this Car On Terrain project from (where it appears in JavaScript) into Processing (Java). He loved doing it in a form of a lesson for me, while I was filming him and asking questions about loops, arrays, fixtures, shapes and bodies (and there are many things I don’t understand). Simon also spoke about “the three most important properties: density, friction and restitution”. The project involved a lot of Physics, using many Box2D sub-libraries and translating between pixels and mm.

In the end, he got tired of writing all the coordinates for the terrain vertices, but he did get quite far.
