10AM Scratch Level 2

February 2, 2019 @ 10:00 am - 11:00 am
  1. We continued enhancing Spaceship project
    1. We changed fireball image into a better one.
    2. We put a limit on the number of fireball to 10.
    3. We added a logic that would make fireball destroy the asteroid.
    4. We added a logic that would make asteroid faster every 10 seconds.
    5. We learn about “mod”. https://www.khanacademy.org/computing/computer-science/cryptography/modarithmetic/a/what-is-modular-arithmetic
  2. Homeworks:
    1. Review Spaceship project and if you don’t understand any of the script of behavior, please compile list of question.
    2. Draw a square shape in scratch using “change x by” and “change y by” only. At the beginning of the script, you can use “go to x: 0 , y:0”. After that you cannot use goto anymore, just change x/y by script.
