After doing some drawings to figure out how a level of Evolution Nine should look like, I used Box2D to draw what could be the first level and then put a rectangle jumping about randomly on it.
First I did it by creating one more test to the Box2D Testbed application, but after switching the project from Box2D/C++ to Box2dWeb/JavaScript on HTML5’s canvas I rewrote it accordingly.
Here is what it looked like:
I did this by modifying the demo.html file included with Box2dWeb.
A link for a newer version of this prototype will be up soon.
