Apple Game Frameworks and Technologies: PhysicsCategory.floor was renamed (p 87)

On page 86 is this line of code:

self.physicsBody?.contactTestBitMask = PhysicsCategory.player
                                     | PhysicsCategory.foreground

On page 87 is this text:

Notice here that the contactTestBitMask is set to both the PhysicsCategory.player | PhysicsCategory.floor categories

The text references PhysicsCategory.floor while the code references PhysicsCategory.foreground. foreground is what the code has referenced up until this line. I believe floor may have been renamed to foreground at some point and this reference didn’t get caught.

Hello, David.

Nice catch. I’ve updated the text to fix the incorrect reference. You’ll see this update in the next release.
