4. Some sprites have costumes

5. Costume changes give the illusion of movement.
This program says:
After the flag is clicked, put on avery-a costume. Wait a ½ second and put on avery-b costume. Wait a ½ second and put on avery-a costume again. The forever loop means it will repeat until the program is stopped.

Hold down control while you click on a costume to bring up these options (or right click).
Choose duplicate.

19. Try running your program. (Press the green flag)

20. How does this work? What is the trigger to run the code?
The green flag
What do you think this does?
It causes a loop which repeats the code 10 times
Why do we need these wait commands?
It spaces out the commands – otherwise they would all happen at once and cancel each other out

Add it in the middle of your program.
