Digital Workshop

I am currently working on a quiz that has 10 questions that must not repeat or show up in the same order every time. The quiz works fine the first time it is taken by the learner, but the issue arises when the learner re-takes the quiz due to failure of the quiz. The quiz is set up to where they must make a 100% on the quiz to pass, otherwise they must re-take it until they make the 100%. When the learner hits the re-take quiz button that takes them back to the first question it resets "all variables" and then continues randomly selecting quiz pages until it reaches the denoted 10 questions. It will randomly choose pages to go to, but then starts to repeat quiz pages and leaving at least one that never shows up. The pages are all set up where the "next" button will "GoTo next random page". This results in a very close to desired outcome, but still leaves one or more quiz pages out and repeats that amount.

My main question that arose was if someone has created an action script or custom action that can toggle a page's Miscellaneous property, "Exclude from Goto Random Page list"?

That small check box if possible to toggle will solve this repetition problem. Any tips or suggestions will be greatly appreciated.


Thank you all for your dedication to working on Opus and making it a great program!

There are loads of posts on randomising pages - so worth searching.

There is an example of generating random lists from a fixed pool here:

See the functions example.

Hi CJMAC

Macavi's solution is probably the way to go but you could also have a look at some old lessons that I posted on this forum.

Lesson 5 could probably assist you solve your problem.

It's here http://www.digitalgrapevine.info/viewtopic.php?f=13&t=1614

Thank you all for your help. We have successfully implemented the random quiz and it is working flawlessly. We had to stick to a 10 question quiz with no questions left in a "pool" simply 10 for 10.

Everyone's help is greatly appreciated.

I am currently creating a test featuring a bank of 20 questions and 8 questions to be selected at random with no repeat questions. As preparation I have downloaded the publication sugested above at: viewtopic.php?f=4&t=4083&p=20811&hilit=random+list#p20811 . However I notice it is an Opus standalone publication, but when you republish it as HTML 5 the quiz won't run. Is there something in the scripts that stop it working in HTML5?

If this example cannot run in HTML5 can someone point me to a different template that I can base my publication on?

Thanks.

This is one of those questions that shows why Opus HTML is simply so great to use.

1. You don't need some old forum code as any JS shuffle of the internet will work.

2. The Opus JS library contains loads of useful functions that make building things like this easy.

Here's the code:


In this instance, I have adapted the JS function so you can simply place it within an Opus Script object. I've included the line:



But you should call this when you're ready to change pages, simply swap out the hard coded 0 myPage for your own value or incremental variable to pick the next randomised page in the pool.

Hi Mack,

Back to this project again! I have managed to create the variable which will have each question page name in each of 23 elements.
The variable is created OK and I can see the elements in a text box, However I am stuck at the shuffle action? It just won't work.

Here is a summary of what I have done so far:

//Create a Publication array variable "questionbank" with 23 elements
var questionbank = new Array[23]

//and then name the 23 elements
questionbank[0] = "Q1"
questionbank[1] = "Q2"
questionbank[2] = "Q3"
questionbank[3] = "Q4"
questionbank[4] = "Q5"
questionbank[5] = "Q6"
questionbank[6] = "Q7"
questionbank[7] = "Q8"
questionbank[8] = "Q9"
questionbank[9] = "Q10"
questionbank[10] = "Q11"
questionbank[11] = "Q12"
questionbank[12] = "Q13"
questionbank[13] = "Q14"
questionbank[14] = "Q15"
questionbank[15] = "Q16"
questionbank[16] = "Q17"
questionbank[17] = "Q18"
questionbank[18] = "Q19"
questionbank[19] = "Q20"
questionbank[20] = "Q21"
questionbank[21] = "Q22"
questionbank[22] = "Q23"

//couldn't get this to work "questionbank = new Array('Q1','Q2','Q3','Q4','Q5'...........);"

//Shuffle the 23 elements
function shuffle(a) {
var j, x, i;
for (i = a.length - 1; i > 0; i--) {
j = Math.floor(Math.random() * (i + 1));
x = a[i];
a[i] = a[j];
a[j] = x;
}
}

The last bit I don't really understand so not sure if I have to edit further.

You haven't called the function. You need to add this line after the array has been defined.

Thanks Mack, that worked. Now I have to get it to work through each of the questions without repeating them.

You just read the read array and set the pointer to next value each time. IE:

First random question is at questionbank[0], second random question is at questionbank[1] but unless you want to manually change the cell value, use a variable and change that:

// do this each time you want to change question.
</mack>

Still struggling with this.

I have completely rebuilt my random question quiz using a bank of 23 question. However although all is well in the Opus editor when I publish to HTML5 the shuffle action will not then work. It's OK in the editor.

Simplified pub attached which show the problem when published.

Can Mack or someone tell me what I have done wrong please?

Add this line to the top of your script before you define the elements:
