[solved] Countdown display

I need to create a 30 second countdown display for an experiment I'm designing. It will occur automatically after an instruction screen and session 'X' of the experiment will follow the countdown. Essentially it will act as a distractor so that instructions are not maintained in participants WM.

Unfortunately I am new to OpenSesame, programming in general (let alone Python). Please assume complete naivety with regards to programming!

Any help would be great - this probably will not be my last SOS...

    Please ignore - figured it out with a feedback loop!

    Great. Consider it ignored. ;)

    There's much bigger issues in the world, I know. But I first have to take care of the world I know.

    Create a feedback loop with variable 'countdown' (or whatever!). Insert the numbers 1 thru 30 into 'countdown'. Create a sketchpad item within the fb loop and insert your variable using the square brackets method (I.e. ['countdown']). That should do it!

    Count you or somebody explain this in more detail? Thanks!!!

    Hi Viennese,

    Basically, you need to create a sketchpad for every second that you want to present. So, if you want to have a 3 seconds countdown, you need to have three sketchpads, each having a duration of 1 second. In the first one you write something along the lines of "The next block starts in 3 seconds", for the second sketchpad, something like "The next block starts in 2 seconds" and so forth. If you feel like it, you can also implement this via a loop (if you have a countdown of 30 seconds, it is a little tedious to create 30 sketchpads).
    Does that clear things up?
