Timing how long an interaction takes.

Hi Lance,

I'm not sure if this is what you're looking for but this is how I implemented it.

when the timeline starts I fire this JS:

var d = new Date();

var player = GetPlayer();

var start = player.SetVar("gsStart", d.getTime());

when the interaction has finished:

var d = new Date();

var player = GetPlayer();

var start = player.SetVar("gsEnd", d.getTime());

Using start and time you can perform the calculation you need.

I'm new to Storyline, and not familiar with JS. How would I go about doing that?

Add triggers to your interaction.

Specify Execute Javascript as the action.

Click the Script button

Enter Javascript code

Hello, Berno, your solution is quite cutting edge, could you share the story file ? I tried to add js trigger on my slide, but failed.

Hello Jon,

I had some JavaScript startup trouble as well.

Maybe this will help.

Thanks Berno. So can I just copy and past what you put in the first post into triggers at the beginning and the end of the interaction?  How would I go about doing the calculations.... Sorry for so many questions. I really have no experience with JS.

With some additional effort, a time-remaining graphic could be added to every slide....

Lance,

Yes, you can copy and paste the JS code in triggers.

Regarding the calculations:

var player = GetPlayer();

var start = player.GetVar("gsStart");

var end = player.GetVar("gsEnd");

var duration = end - start;

You may want to divide by 1000 because the start and end time is in millisecond.

var duration = (end - start) / 1000;

Hello, Berno. Could you screenr how to use your js code ?
