I’ve mentioned the excellent SpriteHelper and LevelHelper tools in the past that allow you develop iOS games faster by providing tools for easily creating spritesheets, laying out levels, and generating Box2D physics code.
I’ve also mentioned some great tutorials on getting started with LevelHelper and SpriteHelper, and what I really liked about them was the ease of use and the relatively low cost considering how much easier these tools make things. Since then I’ve become even more impressed with the tools as the developer has been quickly adding in new features.
If you’ve held out on picking up these tools because you were afraid you wouldn’t be able to use them the creator of these tools, Vladu Bogdan has created an epic but easy to follow tutorial where you create a game similar to that of Jetpack Joyride (well at least you use a jetpack!).
Here’s a video of the game created with the tutorial in action:
As you can see there are quite a few things going on with collisions, physics, and animation all done using a minimal amount of code.
You can find the complete tutorial in 4 parts (don’t worry despite the large number of parts it really doesn’t take THAT long to go through just that there are a lot of screenshots).
