Assessment 2

2. Scratch was the program I chose to
create my project.
The tips area was very helpful and shows
you step by step instructions on how to
create a game. After following the
tutorials, it is then much easier to start
inventing new elements to your program
by following the patterns of data given in
the examples. Click on the link below to

3. Abstraction
In the following slides, I
have used abstraction to
explain the key steps of
creating my game in
scratch, without
unnecessary details.

4. Choose a background
 Click on new backdrops & choose:
• From the library
• Draw your own
• Upload picture
More than 1 can be chosen to change
between.

5. Data Collection
Definition - Data collection is the
process of gathering and
measuring information on targeted
variables in an established
systematic fashion.

6. Click on ‘choose sprite’
• From library
• Upload or
• Draw
Choose a sprite

7. Animating sprite
• Go into costumes
Use the draw option to modify

8. Select script then looks tab.
By entering in specifications for the algorithm, the computer will change
between costume a and b)
Changing your sprites look

9. Making your sprite move
• Go into scripts
• Select tab required
Events tab will tell sprite when to
will do something
(example - when this sprite is clicked)

10. Motion
Motion tab – tell your sprite to
move
move -20 steps
move 20 steps
Control key will
• add a pause between
commands or
• repeat a set of commands.
( wait 0.3 seconds).

11. Adding sound
Sound key
• from the library
• record your own sound
• upload a sound
I selected:
• Library – bubble
• Record own – I’m hungry

12. Refining
The idea was to add text to the
different costumes (balls) so
they depicted the all of the
letters in the alphabet.
When the sprite caught them he
would say the letters name and
the sound it makes.
Unfortunately was unable to de-
bug issues in time frame.

13. Coding the second & third
sprite
Using looping repeats the same
algorithm indefinitely.
To add bubbles – (create new sprite)
Sending sprite (ball) to random
positions)
Scoring

14. Implementation
Definition - actual automation of
an algorithm (Moodle unit 7)

15. When these algorithms are
initiated, they make the
sprite –
• look like it is moving
• opening/closing claws
• & mouth
• Bubbles and sounds in
the background
• Move sprite to catch ball
• Score
