Classes I wrote for implementing joy sticks using iOS's sprite kit library; please see the video below. The images are under copyright (which I lack permission to share any further than this demo), so they may not be used. However, feel free to use the code in your own projects; just swap out the images. This project also serves as a good starting point for a game developed for iOS. The code wasn't intended to be shared (this was mostly a proof of concept) so the documentation may be lacking. I may update if there is interest. The code to create a scene with an actor sprite and grass are provided to demo the joy sticks; you use that code also. Please provide a reference to this git page if you decide to use and or modify the code in your project. :)
