Airplay SDK – Free Commercial Game Framework For Indie Devs

I came across a game engine that I had not previously mentioned on this site, the Airplay SDK thanks to a visitor comment on my iPhone game engine post listing open source game engines. While this is not an open source game engine, it is free to publish iPhone games provided your company has net earnings of less than $100k US dollars per year (with a splash screen).

The engine is also cross platform supporting iPhone OS, Android, Samsung Bada, Symbian, Windows Mobile, BREW, Palm/HP, webOS, and Maemo. It is not specifically a game framework, and can be used to make rich applications of all sorts, but high profile games have been created using Airplay including Call of Duty: World at War: Zombies.

As far as graphics go, the SDK supports 2D and 3D graphics, and something I really like is that it loads in models from Maya and 3D Max. I haven’t had a chance to check everything out, but there are many examples included and the game examples look excellent.

There is also support specifically for the iPad.

You can find it here:
Airplay SDK

You will need to register to download, and then obtain the $0 iPhone indie license.

Beginner iPhone Action Game Programming Tutorial

Welcome to my iPhone action game tutorial. This is a step by step tutorial for creating an iPhone action game.

You can see the result of a game running the code in the video below:

The graphics are a bit different with the tutorial (as some of those in the video are being used in an actual project) but that is the result of running the actual code within the tutorial.

Specificially the tutorial features:

  • Loading/Placing Images
  • Animation
  • Touch Events
  • Text
  • Sound Effects
  • Background Music
  • Buttons
  • Resetting The Game

Now before we start there are a few pre-requisites. You should have a basic understanding of Objective-C and will need a Mac with the iPhone SDK installed. The game was created using iPhone SDK 4.0, and the Sparrow Framework. Also note that I created this to be as easy to follow as possible so I used a minimum number of classes/methods to make it as easy as possible for a beginner to follow – I’ve even exclusively used autorelease objects  so you don’t need to worry about memory management (one of the facets of Objective-C many beginners have trouble with).

In case you’re wondering why I chose to go the route of using the Sparrow Framework it’s because I believe it is the easiest iPhone game development framework available for free for a beginner to start with, and it has already been used in a number of games in the app store.

Please share this tutorial by tweeting it or sharing using one of the buttons at the bottom.  If you have a Dzone account you can vote it up here!

You can navigate through the tutorial by using the page numbers at the bottom of each page.

If you’d like to jump right in you can download a project with all the resources loaded in here.

At the very end of the tutorial you will find the completed project with extensive comments, and at the end of every page you will find a project file that will bring you up to that point of the tutorial.

Otherwise if you’d like to go the route of installing Sparrow, and setting everything up you can visit the Sparrow Framework getting started page here which explains the process of setting up an Xcode project that utilizes the Sparrow Framework. You can get just the game assets (graphics/sound) here.

The tutorial is definitely not perfect, and there are probably some spelling/grammar mistakes, but it is the most extensive single tutorial I’ve seen around and might never be released if I tried to perfect it :)

The first thing we’re going to do is start the game scene by displaying in a background image, adding the score and level text, and playing some music.  Go to page 2 by clicking that number at the bottom of this article to go to that page.
