How to replace exp.set in OS4?

Antje

Hello,

I have a bit of an urgent problem. We ran an experiment using an older version of OS, which was programmed by a former colleague. Long story short: the laptop was stolen and on the new lab computers, we have OS4 installed. The experiment does not seem to be fully compatible with OS4 and I'm posting here to see if anyone can help me fix the problem (because my former colleague is no longer available):

The problem is that exp.set does not seem to be supported anymore in OS4.

We use an inline script as first item in a sequence, which specifies:

-------------------------

exp.set('sound_1', examples_y[0])

exp.set('sound_2', examples_y[1])

exp.set('sound_3', examples_y[2])

-------------------------

examples_y are various sound files specified in another inline script preceding the sequence.

Can anyone help me with this?

Thank you very much in advance!

Hi @Antje,

In OpenSesame 4.0, exp.set() is no longer needed because variables are handled differently. Instead, you should use var to store them properly, like this:

var.sound_1 = examples_y[0]

var.sound_2 = examples_y[1]

var.sound_3 = examples_y[2]

This should work the same way, and OpenSesame should correctly track the variables throughout the experiment.

Let me know if you run into any issues.
