  • GPS-based navigation through the theme park. The current position and the best route are shown on the painted version of the parkmap, which is strongly warped compared to the real geography. I solved the problem by developing a standalone editor to define the warping.
  • resource-patching for each resource used in the app. As there where so many resources, I developed a system to patch resources inside the app just by uploading them to a webserver.
  • Facebook and Twitter support
  • inclusion of the ticket shop
  • the app features lots of content, so I used different methods to avoid adding content by hand. For some parts, the CMS of the website was able to produce plists directly. For some other parts, I wrote PHP proxy sites which loaded the park websites via curl and extracted the data I needed.
  • galleries using the three20 lib
  • location-based treasure hunt game
