Thread: feedback location defaults to upper left

  1. #1

    feedback location defaults to upper left

    I am trying to provide keypress feedback for subjects after they respond to a multiple-choice question. The stim, loc, time columns are:

    feedback; .5,.75,0; 2000

    without the semicolons. I'd like the keypress feedback to be horizontally centered and appear about 3/4 of the way down the screen. But no matter what I put in the loc column, the feedback (which is correct) shows up in the upper left corner of the screen (which is not what I want). I've attached the input and styles file here. Any help would be appreciated!

    I am experiencing exactly the same problem. Is there any advice out there?

    It would seem that DirectRT currently cannot parse percentage based location values for feedback stimuli.
    The only solution to this as of now would be to specify values using exact locations, ie. 100,200,0 (100 pixels from the left, 200 pixels from the top) .

    If it is pertinent that percentage based location values are used (rather than exact location values), I may be able to offer a solution to work with this request.

    thanks for letting me know. I'm not too worried about using percentage values, as long as the response appears in a reasonably central location. I will try using pixel values instead.

    it works! to get it to appear in the central location I used the pixel values 375, 250.
    thanks for the help :-)
