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.
Marked As Solved

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