Note to anyone wondering - version 1.1 is compatible with Xcode 7.3. If you are still using Xcode 7.2, you may wish to download the old Xcode 7.2 version of the book (version 1.0), which is available on your “My Loot” page. Hope this helps! ---

I downloaded the 1.1 version, and it appears to be missing some of the assets for the games. For GeometryFighter 01-scenes, I don’t see any ship.scn. Other projects seem ok. ---

Hey, Ray. Love your site and stuff by the way. Anyway, it’s super easy to add Collada files to a SCNScene. You can create Collada with Cheetah 3D, and spit out a dae file, and then the code is just this: func setupScene() { let scene = SCNScene(named: “YourFileFromCheetah3D.dae”)! scnView.scene = scene scnView.allowsCameraControl = true; scnView.autoenablesDefaultLighting = true; scnView.backgroundColor = UIColor.blackColor() } You should really put this in your Book since Cheetah 3D will create way more complex 3D then Xcode ever could. I can send you one if you want. ---

‘ship.scn’ isn’t an RW-provided asset in Chapter 1; it’s an Apple-provided asset in the basic SceneKit project which you’ll be deleting shortly to make room for your own stuff. ---

There are two small slip of the pen mistakes in the Introduction chapter on page 20 in the Book source code and forums section: 1. “other required resources that included as well” should be “other required resources that are included as well”. 2. “making games with SpriteKit” should be “making games with SceneKit”. ---

Never mind, I neglected to see all the helper functions. I think I read the part about game utils and walked away, then when I returned I had forgotten to copy them over. I see where the method is defined now. Thanks. ---

For the Breaker Game (up to Chapter 10) sometimes part of the paddle disappears during gameplay, and the top right barrier. Also for page 175 I find this formula works better for touch controls: `paddleNode.position.x = paddleX + (Float(location.x - touchX) * 0.06)` ---

On page 207 in the last sentence before the bottom image, it says to name the reference node `ball` but when trying to complete chapter 14 on page 250. When getting a reference to the ball programmatically it will find the reference node ball, not the actual ball so none of the contact delegate code is called. I figured this out by looking at the completed challenge which left it with the default name. ---

P. 209, Obj\_pillar1x3 says to set size to (x:1, y:3, z:1), but texture could not be made to look like the picture on that page with 10 squares tall by 2 squares wide. Pulling up the finished project in the example file showed that this object’s size is (x: 0.6, y: 3, z: 0.6). Setting it to this size did the trick. ---

You are right. Page 207 are wrong and node “obj\_ball reference” can’t be renamed as “ball”. ---

Edited: I didn’t see chrononinja comment on this, I will try that to see if it helps. I know I copied over GameUtils. Hi, in Chapter 3, _Physics_, there are calls to Float.random when applying forces to randomX and randomY which produces an error "Type ‘Float’ has no member ‘random’. I checked the Float Documentation ([Apple Developer Documentation](https://developer.apple.com/library/ios/documentation/Swift/Reference/Swift_Float_Structure/index.html#//apple_ref/doc/uid/TP40015923-CH1-DontLinkElementID_7)) and confirmed. Maybe I am using an incorrect version of Swift, my Xcode is 7.2. ---

not really a typo, but in the book it says to make the shadow for the the follow light to 0.5 but the book shows pictures of a 1.0 shadow, and the demo video shows the 1.0 shadows to this might confuse new scene kit developer so a note to new scene kit developers, if your shadows look less black, and you don’t like this, set the follow\_light shadow back to 1.0 and its a lot darker ---
