Zynga Scroller
The bread and butter of social games are isometric or top down simplified RTS resource building games. If that’s the type of game you are making, you’re going to need a scrolling tile layer to make it work. If you want a smooth-scrolling, mobile-friendly, zoomable scrolling tileset, then you can either spend a good deal of time make a cross-platform compatible one, or just use Zynga’s scroller.
Zynga’s scroller is released under the MIT license and independent of the way you render those tiles onto the screen.
Code is up on github. See more details and demos or try it out below.
