Dear Inquisit experts,
I have a question regarding the undodraw attribute: I have a task where participants are supposed to draw the answer to a visual-spatial riddle (connecting 4 dots). The drawing itself works with the draw attribute. However, I would like to enable the participants to erase their scratch while using a button ("undo") and start anew. However, it just won´t work. I tried every possible combination. Does anyone of you have an idea why not? Here is the code:
<trial loesung1S>
/ stimulusframes = [1=fixation1; 50= mask; 60 = raetsel1S, raetselbild1S, undo, done]
/ correctresponse = ("done")
/ validresponse = ("done")
/ inputdevice = mouse
/ draw = pencil
/ undodraw = [trial.loesung1S.response == "undo"]
/ screencapture = FALSE
/ showmousecursor = TRUE
/ response = timeout(120000)
</trial>
The "done" button works perfectly fine, but when clicking on the "undo" button, nothing happens. Any help is very much appreciated.
thanks in advance, Maxi
