I wrote that I won’t be posting anymore errors on this forum, but I changed my mind. I am stuck on chapter 13 page 367. I build the game to see the bugs animate with the array of animation in Bug.swift. I copied the code exactly how it is written in the book and am getting a fatal error **PestControl[2710:687445] Fatal error: Index out of range** **(lldb)**. this line is getting the RED bar with the words Thread 1:Fatal error: Index out of range : — run(animations[direction.rawValue], withKey: “animation”) – when I comment out that line, I see the bug animations after I build it, but just for the front walk animation for the bug, and not for the back or sideway walk animation. ---

Hi @game_gecko - I checked out the sample code in `final`, and that works. Does it work for you? Perhaps you could check your code against the code in the `final` directory? ---

I started with the starter file from chapter 13, and I always check the final version when I run into a problem, for each chapter. ---

That’s odd then. Please could you zip up your project and post it here? And also tell me the specifications of all the devices that you’re running it on - macOS version, Mac specs, Xcode version, simulator/device version etc. Thanks ---

I have a MacBook Pro, but it has a separate GPU as well as the Intel. I wonder if that’s the problem. Are you able to zip up the whole project and upload it here and see if I can run it? I can’t work out how to test SpriteKit using only the Intel. ---

[starter.zip](https://forums.kodeco.com/uploads/short-url/vdlNA78CQ7bIi18rR5vqZBheLpX.zip) (402.6 KB) I forgot that I started with chapter 12 starter file and worked on it since. I also converted the file to swift 5 version when prompted. So, I don’t know if that had anything to do with the problem I am having? ---

Sorry about the late reply - I didn’t see the notification. In Chapter 12, Beginning Tile Maps, you create a method called `createAnimations`. You appear to have left the final line out, which appends a fourth animation. Add this to the end of `createAnimations(character:)`: ```auto animations.append(SKAction.repeatForever(actionLeft)) ``` I debugged this by adding code before the crash to print out properties to see why it was crashing. I added this code just before the crash: ```auto print(animations) print(direction.rawValue) ``` From that I could see that `direction.rawValue` was 3, meaning it was looking for the fourth element of `animations`. But `animations` only had three elements. So then I tracked down why `animations` only had three elements instead of four. The reason why the fourth one is repeated, is that left and right animations are the same, only right is a mirror of left. That’s taken care of with changing the sign of `xScale` when setting up the direction in `move()`. ---

Thanks for your help! I will change the code as soon as I get back to working on the chapter. Also, you mentioned about moving the character , I remember that when I moved him to the right the game crashed. Hopefully, I will have no problems with your solution.👍 ---

I hope so! I’m really glad you’re progressing through the book. SpriteKit is a great way to get into making games 🙂 ---
