Mobile Applications


The mobile application is compiled using Adobe Flash for iOS and Android and the content is created/managed via an XML file which resides on the application server.

Source Files include:
- The .fla file viewable in Flash 8
- The .fla file viewable in Flash CS3
- The .swf of both files

Please note: For the purposes of this document, element and node mean the same thing: an xml tag.

There's one 'global' attribute in the xml file, to be found in the quiz tag: If you state "yes", the questions appear in a random order, otherwise they follow eachother up chronologically.

Each question comprises a single block of code, contained in a question tag. The question tag comes in three types: multiplechoice, guesstimate and trueorfalse

The multiplechoice type has only few attributes: there is an (optional) illustration, and that's it. In this illustration attribute, you can define the name of the picture or swf file you wish to load into the movie. It doesn't have to be in the same folder, you can define a path to an item on sever. The answerillustration attribute is similar to the illustration one. Here, you can link to the picture or swf file you wish to display on the answer-page.

The guesstimate type has three attributes :
answer. This attribute contains the value of the exact, precise answer.
margin. This attribute contains the value of the margin around the answer that'll still be counted as correct.
Example: if the answer is 12, the margin is 3 and the user guesses 10, it is correct - 10 is between 9 (12-3) and 15 (12+3). 17, however, would be incorrect.
illustration. This works just as with the multiple choice. It's an optional attribute where you can define the path of an illustration.
The answerillustration attribute is similar to the illustration one. Here, you can link to the picture or swf file you wish to display on the answer-page.

This question type is the easiest. There are two attributes: answer= can be either 'true' or 'false. Be sure not to forget the ' and ' around true or false!
illustration (see above) The answerillustration attribute is similar to the illustration one. Here, you can link to the picture or swf file you wish to display on the answer-page.

Other than attributes, all three types of questions contain child nodes! These are all explained below:

This childnode defines the actual question. That what is within the tag, is printed into the question field in the quiz file.
You might notice the tags. These make sure all text within the tags is not evaluated at all.
This basically means that you can freely use apostrofes and less-than or greater-than signs without worrying about anything.

This childnode contains the explaination that is given after the correct answer is shown. Again, you'll notice the tags. Simply type your explaination between them.

The multiplechoice questions (and ONLY those) contain the following childnodes as well:
Within the element, each answer is stored individually in an node. Inside each node, you will find the answer that it conveys. These are also stored between CDATA tags, as explained earlier.
The element also has an attribute: correct.
By defining this element as "no" or "yes", you can let the quiz know which answer is the correct one.

Be wary though! Mark only one answer as "yes", and the rest as "no". Failing to do so might cause the quiz to mess up.
