Hi Unity3D peeps! Just wanted to showcase a game we made with Unity iOS, it just released today on the app store. We're throwing a giveaway party right now at our Facebook and Twitter pages, so join in on the fun! You can win if you follow us on Twitter and tweet "@VAVAinteractive I want Paper Streetball!", or if you like our Facebook page and comment on one of the Paper Streetball wall posts. But what I really want to talk about here is what happened behind the curtains. Farseer Physics 3.1 Sprite Manager 2 Openfeint plugin The Farseer 3.1 version did have a bug when the ball just didn't bounce every now and then and we had to use Farseer 3.1 because I coudn't compile 3.2 using Unity's Mono. Conclusion: Using Box2D next time. Sprite Manager 2 was a lot of help with sprite atlases, but proved to be a giant pain in the ass for this game's scenario (maybe if I had sprite animations it would have been more helpful) Mixing depth of various sprite sheets just doesn't work (or isn't very well explained in the docs). Constant rebuilding of sprite sheets just blew my brains out. Conclusion: Using my own solution for sprite atlases when I don't need sprite animations. Openfeint worked Just took a while to build every time, but I guess I can't complain about that..
