Exercise 11: Multiple Choice Tester
A great way to learn about programming in Scratch is
to examine other people's projects. That's what you are asked to do
here. You could say that you have already been doing that, but here
you won't be given detailed help as before. Here is the project:
Download the project by clicking
HERE then
open it in Scratch and try to figure out how it works. Here are a
few hints:
 |
All the questions are stored in different stage
backgrounds. That means the question number is the same as the
number of the background, so when the fourth background is
displayed, for example, then question four is the current
question. |
|
All the answers are stored in a list. That means
the program can know the total number of questions by looking at
the length of the list i.e. the number of items in the list.
|
|
To make sure that the dark text of the questions
is legible I lightened each background picture in Paint Shop Pro
before importing into Scratch. |
Once you have figured out the program works do the
following:
|
Make a nasty image appear when a wrong answer is
given, just as a smiley appears when a good answer is given.
|
|
Add sound effects. |
|
Add another four questions of your own choosing,
with appropriate images. Don't forget to add the corresponding
answers to the list. |
|
Extend this project in original ways. |
|
Examine the 250 thousand projects that have been
published to the Scratch website at
http://scratch.mit.edu.
(OK, you don't have to look at all of them...) |
