MoleMash App: Conceptualize and Customize
As a Group discuss and answer the following questions each on
an individual sheet of paper. Staple all group papers together
and turn in on the podium. Don’t forget to put your name on your
paper.
Topics
Canvases, ImageSprites, incrementing values, introduction to procedures
Discussion Questions
1. Name the event that isn’t a user-initiated or external event.
2. What function call blocks are used to move an image sprite within the canvas? What are
the function's parameters?
3. If you didn't have a MoveTo block, what blocks could you use to move the mole?
4. What is the unit of measurement for location on the canvas?
5. The version of MoleMash shown above defines a procedure. What is the procedure’s
name? Could you code MoleMash without defining the procedure? Why do you think the
procedure was defined?
6. Describe the effect of the blocks within the MoveMole procedure. Why is the subtraction
performed?

7. The X and Y property of an image sprite specify the sprite’s location. But a sprite is not
a single point, so what specific location does ImageSprite.X and ImageSprite.Y denote?
8. Sketch the blocks so that the Mole moves twice as fast each time it is touched.
9. When a row of blocks is performed, in what order are the blocks executed?
Customization Exercises
1. PERSONALIZE YOUR GAME: Customize the app with a different image (not a mole), a
canvas background image, and custom sound effects.
2. Add a label to keep track of and display the number of times the mole has appeared
(moved).
3. Add a second ImageSprite with a picture of something that the user should not hit, such
as a flower. If the user touches it, penalize him by reducing his score or ending the
game.
4. Allow the user select a picture for the “mole” using the ImagePicker component.
5. Allow the user to specify how fast the mole should move either with faster/slower buttons
or by entering a number in a textbox. The number should be in "jumps per second" and
this should be clear to user. If a textbox is used, constrain the app so that the user can
only enter a number that is reasonable for the speed of the mole. If the user enters an
invalid number, display an error message using the Notifier component and keep the
speed as it was.
6. Show the user's score using a colored bar that changes in size instead of a label.
7. Add "levels": when the user hits the "mole" x number of times, make the mole go faster
automatically and show the user that the level has changed.
8. Keep a high-score for the user and display it in the app.
