Group: Forum Members Posts: 5, Visits: 20	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

Any help is very much appreciated. thanks in advance, Maxi "undo" needs to be specified as a /validresponse (it isn't in your <trial>) and you'll want to restart the trial in case of an "undo" response. Something like: <trial loesung1S> / stimulusframes = [1=undo, done] / correctresponse = ("done") / validresponse = ("done", "undo") / inputdevice = mouse / draw = pencil / undodraw = [trial.loesung1S.response == "undo"] / screencapture = FALSE / showmousecursor = TRUE / response = timeout(120000) / branch = [if(trial.loesung1s.response == "undo") trial.loesung1s] </trial> <text done> / items = ("DONE") / position = (40%, 90%) </text> <text undo> / items = ("UNDO") / position = (60%, 90%) </text> <block myblock> / trials = [1=loesung1S] </block> <shape pencil> / shape = circle / color = green / size = (50px, 50px) </shape> Hope this helps.

Hi Dave, excellent, thank you so much it works now :). I would only have one final question regarding this. Is it also possible that participants only draw when they hold the mouse button pressed otherwise not? All the best, Maxi

Hi Dave, excellent, thank you so much it works now :). I would only have one final question regarding this. Is it also possible that participants only draw when they hold the mouse button pressed otherwise not? All the best, Maxi No, that isn't possible using the /draw attribute and a single <trial>. You could build something approximating this, which however will be more complicated. See e.g. the examples here: https://www.millisecond.com/forums/FindPost4421.aspx If you run the "ShowMouseTrail" script, clicking the left mouse button will enable "drawing", clicking the right mouse button will disable drawing, and you can move the mouse cursor to a different position and start drawing from there by clicking the left mouse button again (and so forth). The Trail Making Test script in the library might be another script worth looking at for perhaps useful additional ideas and usage of /draw: https://www.millisecond.com/download/library/trailmakingtest/ Hope this helps.
