This guide goes through the telltale signs of terrible questions asked on stackoverflow. You’ll learn how not to ask questions.

If instead you like to learn how to ask good questions you came to the wrong guide. You may also want to learn to tell people what the Matt you’ve tried so far.

Okay, admittedly I make some poignant observations and suggestions that can be seen as helpful.

If you have been given this link as a response to your question on stackoverflow.com, please don’t take the following personally. I do not intend to offend or insult you, it’s just that I’ve become a little too annoyed to not point out the flaws directly and admittedly without sugarcoating them. Nevertheless there’s good advice in here and I’m sure you’ll know how to apply that to your question and you will get (better) answers because of it. I’m just trying to vent .. help. :)

Any Ideas? Suggestions?

So tell me, what you you really want to know?

You can’t expect stackoverflow users to give random suggestions and guidance. This is not what stackoverflow is about. It is about concrete problems that are likely to have a specific answer (or two).

If you don’t know what specific question you should ask then it’s the same as not asking anything at all. It tells everyone you did not understand your problem well enough to ask a specific question about the problem. Which means any suggestions are very unlikely to point out the flaw in your thinking, or even nudge you in the right direction.

Worse, in some cases it’s obviously just poor laziness. You don’t even want to invest time in properly asking a question? Fine, but please don’t do that on stackoverflow.

… is not working (properly).

“Not working” is not a problem description. You can say “my car is not working” if you need an excuse for your boss why you’ll be late to work. But even a mechanic won’t be able to diagnose your car’s problem if you can’t describe what you were doing and what the car did.

Learn SpriteBuilder Phew!

I’m done writing the Tome of SpriteBuilder.

There’s only edits and reviews left, page proofing and then it goes out to print. Meanwhile, I’m cleaning up and extending the Bouncy Beast project for its App Store release.

Time to share some insights as I haven’t been able to slice some time off to write about the process as I originally intended to.

What’s in the book?

In the Learn SpriteBuilder book you will learn SpriteBuilder step-by-step while building the Bouncy Beast game.

The book will guide you through the creation of a physics-driven, parallax-scrolling game with the help of SpriteBuilder, Cocos2D (cocos2d-swift) and Objective-C. The level-based structure will enable you to add more content to the game, even without writing additional code.

As your guide I will walk you through the individual steps necessary to create the game project. Along the way I’ll explain the SpriteBuilder features, caveats, workarounds and helpful tips and tricks as you are most likely to come across or need them.

978-1-4842-0263-0_Figure_13-16 At the end you’ll have a complete game reminiscent of games like Badland.
The game also runs on Android devices thanks to Apportable’s Android plugin for SpriteBuilder.

The Bouncy Beast project’s source code will be available.

Bouncy Beast Demo Video

Here’s a video demonstrating the game. Notice the subtle particle effect on the main menu’s background, the paginating scroll view, the soft-body player character.

NOTE: the suboptimal framerate in the video is 100% attributable to the iOS Simulator from which I recorded the video. On an iPod touch 5G the game runs with a constant 60 fps.

Learn SpriteBuilder book: Progress Update #1

On July 11, 2014, in book, idevblogaday, by Steffen Itterheim

978-1-4842-0263-0_Figure_04-11

Since the announcement of the Learn SpriteBuilder book I’ve submitted the first three chapters to Apress.

Actually it’s chapters 2 through 4 because I’ve learned that the details in the first chapters tend to change significantly. This includes version numbers but also highlighted features, tool and project names, and so on.

Chapter Summary

Following is a summary of each chapter thus far.

Chapter 2 “Laying the Groundwork” first introduces the SpriteBuilder user interface but also Cocos2D (-iphone/-swift) programming basics. I really went above and beyond existing SpriteBuilder user interface tutorials to explain even the smaller details that boggled my mind when I was learning SpriteBuilder. You’ll learn the difference between Scene, Node or Layer CCBs. The effect of position, content size and scale modes (points, UI points, %, insets). What all the nodes are and what they are used for. But also how to make the code connections and what the difference between CCBReader load and loadAsScene is. The importance of Sub File nodes and the Tileless Editor View.

At the end you’ll have a firm grasp on SpriteBuilder basics and a project framework with two scenes and transitions between both scenes.

I’m excited to announce that I am writing a new book, titled Learn SpriteBuilder. It will be published by Apress and is both sponsored and supported by Apportable with top-notch graphics.

Over the course of the book you will create a level-based, parallax-scrolling game that’s not unlike Badland with some elements from Leo’s Fortune. The game will be complete with main menu, settings, level selection, pause and game over menus, music and sound effects, and room to extend the game with your own ideas, levels, code and other content.

Learn SpriteBuilder is not a direct sequel to ‘Learn Cocos2d'; its focus is on teaching efficient workflows with SpriteBuilder and demonstrating the connection between SpriteBuilder and cocos2d-iphone v3 (now known as cocos2d-swift). Still there’s plenty of Objective-C code necessary to build an iOS game and I’ll take extra care to explain it well, in particular the new Cocos2D v3 features.

The Learn SpriteBuilder book is aimed at beginning to intermediate Cocos2D and SpriteBuilder developers but also experienced Cocos2D developers who are interested in learning more advanced concepts. Among them are the new visual effects system currently in development for Cocos2D and a fully textured, deformable soft-body player character.

Three chapters alone are dedicated to physics editing with SpriteBuilder and physics programming with Objective-Chipmunk.

Xcode’s QuickLook debugging feature allows you to get more details, and be more visual with your debugging data.

For example you can even grab a screenshot of the cocos2d screen and display it right within Xcode:

Migrating to cocos2d-iphone v3 – Tips & Tricks

On March 6, 2014, in idevblogaday, by Steffen Itterheim

This is a collection of Tips & Tricks for users who are migrating to cocos2d-iphone v3 from v2. Mostly refers to questions posted on stackoverflow.com.

Please excuse the short, bullet-pointed format. I’m a little short on time but didn’t want to miss out on another biweekly post like I did two weeks ago (first time in about 4 years, ouch).

General Tips

  • Many classes have been renamed…

“Use the source, Luke!” If you don’t find what you are looking for:
– Check the cocos2d API class reference
– Start typing the class or method name, see what suggestions Xcode autocomplete has for you
– Use part of the class name (ie “repeatforever”) and perform a “Find in Project” to search through all source code files

  • Tutorial XYZ won’t work with v3!

Yes, it won’t. Most likely it was written for cocos2d-iphone v2.
Question is: do you have to use v3? And do you have to use it right now?
Because if you’re in the process of learning cocos2d it’ll be easier to learn from and with v2 tutorials/books for the time being until more v3 tutorials have been published.

  • How to upgrade an existing cocos2d v2 project to v3?

The Mobile 2D Game Engine Popularity Index – January 2014

On February 6, 2014, in idevblogaday, by Steffen Itterheim

This is an update to the Mobile Game Engine Popularity Index I published 2.5 months ago.

Game Engine Popularity on Stackoverflow.com

stackoverflow tag popularity

stackoverflow tag popularity


Since November’s chart I made sure the tags I’m most interested in (cocos2d-iphone, cocos2d-x, sprite-kit) were properly applied to all questions.

Furthermore I update at least the past 6 months for each tag, which caused the graph to change noticeably. This may be due to policing the site, where users remove tags or retag questions. The net result is that there are now recent months with fewer questions for some engines compared to November’s chart. In particular this flattened the up-down curve of cocos2d-iphone.

The Guide to Building and Customizing SpriteBuilder v1.x

On January 23, 2014, in idevblogaday, by Steffen Itterheim
Custom-built SpriteBuilder with MySprite node plugin

Custom-built SpriteBuilder with MySprite node plugin

Following the recent release of SpriteBuilder and cocos2d-iphone v3 I’m sure some of you are itching to use SpriteBuilder by building the github version in Xcode rather than downloading it from the Mac App Store. Here’s how!

This is a post for developers who want to compile the SpriteBuilder code from github. To customize it, to debug issues, to add or gain access to new features; be it for their own use or to help the project, or both.

Previous experience with Xcode, Objective-C, cocos2d-iphone, git and github is assumed.

Download SpriteBuilder from github

The download and first-time compilation procedure is also detailed on the SpriteBuilder github page. You need to clone the project, then initialize the cocos2d-iphone submodule. The necessary Terminal commands are as follows:
