Reply To: Using if statements during a trial

[Jeremy]

Hi Max,

I’m sorry, I went too fast when posting my answer, here is a revised version of the code:

newTrial( "experiment" ,
    newText ("FullText", row.FullText),
    newButton("FTButton1","Proceed to next Trial"),
    newButton("FTButton2","Proceed to Comprehension Question"),
    newText("CompQ",row.CompQ),
    newButton("CQButton","Placeholder, just click to answer"),
    getText("FullText").print(),
    ( row.CompYN=="Y" ? [
        getButton("FTButton2")
            .print()
            .wait()
            .remove("FTButton2","FullText"),
        getText("CompQ")
            .print(),
        getButton("CQButton")
            .print()
            .wait()
            .remove("CompQ","CQButton")
    ] : [
        getButton("FTButton1")
            .print()
            .wait()
            .remove("FTButton1","FullText")       
    ] )
) //closes newTrial

Besides the lack of double-quotes around Y, the problem was that each comma-separated block of commands represents an object, but the ( test ? success : failure ) structure allows only one object in success and failure. There technically were three objects in the success part of the original code, so the first two were ignored. The solution I just proposed is to package the three objects into a single array: because newTrial treats commands packaged in an array the same way as direct series of commands, you still get the intended result.
