- 26. Scenes • Screens in your game • Can almost think of them as separate apps Thursday, October 1, 2009
- 27. Layers • Take up the entire screen • Setup to handle touch and accelerometer • Can contain other layers and sprites (and other stuff) Thursday, October 1, 2009
- 28. Sprites Thursday, October 1, 2009
- 29. Director • Manages moving between Scenes • Pausing and running Scenes • Sets up OpenGL ES • Layer asks Director to move on Thursday, October 1, 2009
