Cannot add PBox2D library to sketch

tomchambers

I'm following the instructions in The Nature of Code and cannot get the Box2D example to work. I get the error:

The package pbox2d does not exist. You might be missing a library

The example code is this:

```PBox2D box2d;

void setup() { Initialize and create the Box2D world. box2d = new PBox2D(this); box2d.createWorld(); }```

I have installed the library through add tools, and I can see the library in my 'libraries' folder as shown.

Most assured way to import an installed library is clicking at "Sketch".
Look for its "Contributed" section. You should find "Box2D for Processing" for clicking at.

Just gave that a go, I now get import shiffman.box2d.*;. My other problem is that the class has been renamed to Box2DProcessing from PBox2D, but I was following the instructions in the book which call the library by its former name.
