Hi,

this is really not enough information. Control what with the mouse? If you want proper support, you have to give more detail.

PS. MAybe the mousetrap plugin could be useful to you: http://osdoc.cogsci.nl/3.1/manual/mousetracking/

Hello everyone,
Following the above, after they define the radius, I want to give them feedback on success / failure in the task.
Because it's about pixels, I want them to get positive feedback if their response is within 20 pixels of my answer, and if it's outside of that range they get negative feedback.

Can you help me with this?
Many thanks

eduard

Hi,

After the response was given, you can add this code:

if r<20: # I assume r is the variable that represents the radius
    var.correct = 1
else:
   var.correct = 0

Then you can add a feedback item that shows the feedback in accordance with the value for correct. (Checkout the beginner's tutorial for an example).
