Nested if conditions

I am curious what an example use case might be.

I used nested if/then statements at lot when I worked in HyperCard (so a long, long time ago, in software terms).

At this time, Storyline doesn't support nested conditions. You could submit a feature request:

Note: Submitting a request doesn't guarantee that a feature will be implemented. But the number of people who request a feature might have some impact on the decision-making process.

Earlier versions of Storyline didn't even include "Else" statements. Thank goodness that we got that, at least. 

For more complicated sets of if-thens, you need to create separate triggers.

Keep in mind that triggers run in order. Also, a trigger can't run if a previous trigger has already jumped to another slide.

If you want to accomplish this and can't just use multiple AND & OR conditions in the initial trigger there's a couple of options:

[1] Use the base trigger to open a new layer and then add a 'on timeline start' trigger(s) to the layer that uses your additional condition(s). Make sure to add a final 'on timeline start - hide layer' trigger so you can re-show the layer.  You're kind of treating the layer as a re-useable function.

[2] Resort to Javascript!  I'd need to see an example of what you want to check to suggest how best to code this.  In general I would do something like:

• Set a true/false variable  (let's call it 'jsResult') to false.  You can also use numeric or string variables. Strings are most flexible but let's stick to t/f to keep it simple.
• Run the Javascript check & set jsResult to true if your condtions are met
• Add a 'when jsResult changes' trigger that carries out your desired action 'if jsResult = value true'

Does that make sense?
