Recently I need to build a psychological experiment which allows the participant to drag and drop images during the experiment. May I know if it can be done on OpenSesame? What kind of libraries/functions should I use?
Thanks in adcanced!
That will definitely quite a bit of python coding.

There are probably many pygame examples out there: This here for example, looks promising
Good luck and if you manage it would super cool, if you could paste your code here, to use for others.
