    Is there a way to log the actual text of a text object? The situation is that I’m randomly choosing 1 of 12 possible words to use for each trial, and I need to log which one is chosen.

    I’ve tried a few things, but most seem to get stuck on the fact that using getX() doesn’t return a value. So setting a number variable and logging it works, but then I can’t use it to get the word. Alternatively, I can directly get the word by string concatenation (as below), but then I can’t log the word that gets chosen (since logging a text object logs the time it was printed but not what the text is).

    Here’s a link to the experiment: https://farm.pcibex.net/r/PtpjPM/

    And here’s a code snippet:

    
    newText("word", variable["word_" + Math.floor(Math.random() * 12)]).print().log()
    

    This just logs the print time of the text, but not the actual text.

    The alternative I tried is this:

    
    newVar("word_num", Math.floor(Math.random() * 12)).log(),
    newText("word", variable["word_" + getVar("word_num")]).print()
    

    but this doesn’t work because getVar(“word_num”) doesn’t actually return the value.

    What I’d like to do is log ideally the value of the word that gets chosen, but at least log the random number so I can reconstruct that choice later.

    Nevermind; I figured out how to do this. I’ll post it in case anyone else comes across a similar issue.

    
    Template("practice.csv", variable => {
        var word = variable['word_' + Math.floor(Math.random() * 12)];
        return newTrial("trial_prac",
            // ... whatever else you want here
            newText("word", word)
            // ... whatever else you want here
        ).log("word", word)
    })

    Hi,

    newX commands (and their arguments) are evaluated immediately so even if you were able to directly refer to the value of the Var element (which you can: getVar("word_num").value) you wouldn’t necessarily get what you want, because the execution of a PennController trial (and of the commands on its elements) happens, well, whenever the trial is executed

    You could do this instead:

    newVar("random_word", variable["word_" + Math.floor(Math.random() * 12)] ).log(),
    newText("word", "").text( getVar("random_word") ).print()

    or

    newTrial("trial_prac",
    // ...
      word_num = Math.floor(Math.random() * 12),
      newText("word", variable["word_" + word_num]).print()
    //...
    )
    .log("word_num", word_num)
    

    EDIT: sorry, I just saw your second message. That’s a great solution (it’s actually cleaner than creating a variable within newTrial like I suggest)
