  1. Creating Procedures in MoleMashHack Week 2

  2. Procedure • Named sequence of statements • Code reuse • Example without arg: turn on light • Example with arg: make a milkshakenote: non-working code:

  3. Animation • The rapid display of a sequence of images to create an illusion of movement • Based on physical and mental processes of humans • Existed since the 1800s http://www.youtube.com/watch?v=xSrDnIVgVv0http://www.youtube.com/watch?v=_D9P5HZkPys

  4. Computer-based animation • Paper-based animation is slow to make & kills trees • The computer can move an image quickly over time so it looks like it is moving • App Inventor has an Animation component

  5. Debugging • Add Comment • Deactivate • Watch • Do it

  6. Mole Mash

  7. Resources If you have problems • Watch the YouTube videos (Part 1, 2 & 3) • Read the App Inventor book (page 37, 237-240) • Post questions to the Technovation Challenge Google Group
