Setting 'Results.ScorePoints' to equal my custom score variable

Hi Tim,

Thanks for reaching out here, and as you mentioned it's been discussed before as Storyline doesn't currently allow for you to edit the Results.ScorePoints using triggers as it's set based on the questions you've inserted and points associated with them. 

I'll defer to the community for their expertise and will be curious to see what you all come up with! 

I'm hope the answer is going to be in setting the 'NumericEntry' variable to equal my custom 'My-Score' value (as if I had typed it in). I can do this OK. I have created a Numeric entry slide and this slide is included in the 'Results' slide but the 'Results.ScorePoin†s' still doesn't include the 'NumericEntry' value. Aaaaargh!

Tim, you can use javascript to set a score in an LMS.  You could use this to set the custom value to your LMS

Thanks Phil. When I get to the Results slide I will have two variables holding quiz question scores ('Results.ScorePoints' that is accumulated from the standard SL questions and 'My_Score' accumulated from my custom question slides with their individual marking, e.g.: score 0-10 on each screen). I need to combine these two into a single points value and then mark this as a Pass or Fail to the LMS.  

You can use javascript to set your score in the LMS. To do this, you will need to keep track of the scores on your own.

Storyline lets you access Results.ScorePoints to display it on the screen, but you can't read or write it with javascript.

What you can do however, is add a trigger to the correct and incorrect feedback layers to collect that information into your own custom variable. Then you can use it however you want.

Thanks Dave. I am collecting certain correctly-answered question points in my custom variable called 'My-Score'. Other questions use standard SL templates and they are accumulating in 'Results.ScorePoints'.

On the Results screen I am using a Trigger to Add the contents of 'Results.ScorePoints' to 'My-Score' (although I really wanted to do it the other way around). So I do end up with the correct total scored points from custom and standard questions. 

But which variables are returned via the LMS from the Results screen? The SCORM 1.2 Tracking screens just names the Results screen but not the variables. The other standard SL variables for ScorePercent, etc. would also not carry my custom data. Does SCORM send back ALL variables it finds on the Results screen?

Storyline sends the score from the default score variables for the results slide that you have set up as the slide to report to the LMS. You can override that value with javascript, but to prevent Storyline from overwriting it, you have to be careful to send it after Storyline. I do this by placing it after the submit results trigger on the results slide.

This statement:

lmsAPI.SCORM_SetScore(My-Score,100,0);

will send the value of the javascript variable My-Score, a max value of 100 and a min value to the LMS.

I hope that this helps.

Thanks for your rapid help Dave, most appreciated. I'll try this.

Not working yet.

Dave - is anything else required in the Javascript other than 'lmsAPI.SCORM_SetScore(My-Score,100,0);'? Opening the Player, defining vars, etc? 

Well, sure, That statement only sends the score to the lms. 

To do this, I create 3 variables in the storyline player. CurrentScore, CurrentScorePercent, and PassScorePercent. 

Then I add a javascript trigger to each question slide on the correct answer layer to add 10 points to my variable CurrentScore. You need to keep track of this in your own variable, as Storyline does not make the internal score variable available to javascript.

Then I add this script in a javascript trigger that runs after the submit action on the results slide

var p = GetPlayer();

var cs = p.GetVar("CurrentScore");

var currentScorePercent = p.GetVar("CurrentScorePercent");

var passScorePercent = p.GetVar("PassScorePercent");

var ns = 10; // Number of Question Slides

var currentScorePercent = Math.round(cs / ns * 10);

p.SetVar("CurrentScorePercent", currentScorePercent );

console.log("Current Score Percent " + currentScorePercent);

lmsAPI.SCORM_SetScore(currentScorePercent, passScorePercent, 0);

console.log("Score Saved");

You will notice that I've added a couple of "console.log" statements. These are very useful when debugging your code. When you've added the scripts, publish your course for web or lms. Start your course in the browser. When it first starts, press F12 on your keyboard. This will open the debugging tools. (You may need to download these for firefox. Chrome's security settings may refuse to play the flash content with the new security settings if your are running from a local file.) With the debugger window open, select the console tab. The results of the console.log statement may be viewed in the console window. 

Since I'm sending a score percentage, I need to calculate the percent from the actual score. Set the var ns to the number of slide that you have.

I like to debug in Chrome, but with the new security settings, you need to run the module from an actual URL (HTTP//) not a file (file//) designation. I get around this by running it in localhost on my PC. This saves me from having to upload it to the LMS for each test. If you want to set up the localhost server, you will need to add a mime type for .mp4 media content, but once you do it works great for testing.

(I did this from memory, so you may need to check it for typos.)

I hope that this information helps.
