2. Skills

3. Create a new project
Title it Lesson 12

4. We have to add the video sensing extension

5. Now you have new video code blocks

6. Try turning your video on
You also use this code block to turn your video off or to flip your video

7. Try different levels of transparency

8. We can code the cat to sense our movements and to react to them
Add an if loop and an operator that will sense when the video motion on our sprite is greater than 50
(you can decrease the number to make more sensitive)

9. Let’s have the cat hide if we touch him
Note that we also need a show code at the beginning of our program
We also need a forever loop so that the program constantly checks for this condition

10. Does yours work?

We are defining what our new code block will do

18. Look under My Blocks for your new code and add it to your program

19. Your Turn! Make your own video sensing game
Must interact in some way with the sprites in the program
Create your own code block to give yourself a shortcut
BONUS: Can you create a program where the video turns on and off and key times?
