Unit 2 Activity overview

The second unit consists of four activities. General this unit asks for more active work. 

The first activity is about interactions between objects. How can objects communicate to each other and synchronize their actions? This question is answered here.
The next activity is adresses the possibility of storytelling in Pocket Code. With the background object you can easily control the scenes of your story or the levels of your game. 

The third activity is about dependencies. Often actions are depending on certain events. Here you learn how to use dependencies to make your projects more powerful.

As an exercise, you're going to be a debugger in the last activity of this unit again. Find the bugs!
