  • Check out the code in the project below by going to the links and
    pressing 

  • Model: https://scratch.mit.edu/projects/176430425/

  • This game is given out individually as students finish the previous game at their own paces.

Basic Game

  • This game is a review of cloning, because it has clones coming in from edges of the screen. The player clicks on the clones of bugs to squish them and stop them from reaching the donut in the center of the screen.

  • Teaches:

    • Wait block

    • Checking if a sprite is clicked

    • More cloning

  • Make the donut sprite in the middle of the screen.

  • Make a spider sprite that's hidden on the screen- this is the
    master sprite, whose only job is to make clones. It doesn't go
    after the donut like the clones do.

  • Create clones of the spider that appear on a random edges of
    the screen and constantly go to the donut.

    • In this case, have the master spider sprite create clones in
      a forever loop, because the clones will be deleted later.​

  • Program the spider clones so that if they are clicked, they
    delete themselves.

    • Check if a clone is clicked using an "and" block; If the clone
      is touching the mouse pointer "and" the mouse is down,
      then the sprite is clicked.​

  • If any of the spider clones touch the donut, the player loses.

Lesson 5

  • Create a score variable that counts how many bugs have been squished.

  • Add sounds for when a bug is squished and/or for when the bugs reach the donut.

Finishing Raining Cats and Crabs

This is a different way of using clones from Lessons 4/5. This involves hiding the master sprite away while the clones do the work.

  • Students continue working on the Raining Cats and Crabs Game from the previous lesson (see Lessons 4/5)
