Found out about a pretty cool tool for those looking to develop games using Box2D (especially if you’re using Cocos2D — but really good for anyone using Box2D) called SpriteHelper. It is a notch above the other tools I’ve seen doing similar.
What the tool allows you to do is easily gather information on any sprite such as UV, the vertex positions, position of the sprite within another image (for those of you using spritesheets), and the dimensions of the sprite’s rectangle — but most importantly the tool allows you to easily drag and create an outline around the shape, telling you if your shape will work with Box2D, you can then use the generated data, or even generate the actual Cocos2D code for your Box2D shape. Check out this video demo/tutorial:
The tool is currently only 0.99 cents at the moment in the Mac App Store. No word on whether it will go up in price.
You can find it here:
What I think really makes this tool different is just the ease of use, and the small details added to the tool that make things a bit easier. If you are using Box2D, and especially Box2D and Cocos2D this should be a good time saver.
Thanks to the creator Vladu Bogdan for mentioning it in the iPhone and iPad development forum.
