Introduction to Computer Science with Scratch and App Inventor

Now that we know about and and or blocks, we can update our win and lose conditions for our player.
You can use and and or blocks throughout your program any time you want to check multiple conditions!
You can also use the same blocks we have talked about today to create more challenges for your games.
For example, you can:
Create multiple levels – advancing to a new level can be dependent on reaching a certain
number of points, or any other condition
Make your game more challenging as players accumulate more points, for example, I could
make the duck move faster once the dinosaur has 5 points
Be creative! There is no limit to the kinds of games you can create using Scratch!
Adding Sound to Your Program
You can also add sounds to your program. The sound blocks are bright purple.
If you add sounds to your game, please be
respectful of the other students in the lab and
keep the volume on your computer low!
To play a sound, you must first add it to your
sprite.
There are two ways to add a sound to your
sprite. You can either record a sound using a
microphone, or you can import a sound. If you
import a sound, you can use the built in sounds
from the scratch library, or upload your own
sound/music file.
All of the options for sounds are on the sounds
tab in the current sprite pane.
