I have an interesting idea (at least in my mind) for an iPhone game and for the game to work, I would need to have the pinch-to-zoom (and pinch-to-zoom-out) functionality similar to the one you see in say the Google Maps app.
The game “Angry Birds” for instance also has this functionality and you can zoom-in and zoom-out of the game by pinching…
Since my game will take place in a city similar to this one (http://www.istockphoto.com/stock-illustration-12650327-town-plan.php) and I will need to be able to zoom-in and zoom-out of it, my question is, how is this functionality achievable in an iPhone game and do I have to draw the game in a certain program (for instance Illustrator) to make it work?!
Please let me know everything you know about this!!
I personally have not dealt with any SVG graphics creation, but I think PhoneGap is cool because it is supposed to make app building easier as it utilizes technologies that are less foreign to folks already experienced in web design programming languages:
PhoneGap is an open source development framework for building cross-platform mobile apps. Build apps in HTML and JavaScript and still take advantage of core features in iPhone/iPod touch, iPad, Google Android, Palm, Symbian and Blackberry SDKs.
I suggest SVG for your graphics, but you could probably (also) use any other image format.
