Hello, I am very new to PsychoPy and coding in general, so sorry for how little I know. I am trying to create an experiment in which the participant will have to place 15 coloured squares in order (no correct/incorrect order). I have created the basis (in builder mode), with the 15 squares and 15 d…

Hi @Tom_Olive , all you need is a code component and mouse. Make sure your mouse settings is set to “never end routine on press”. Then, say you have shape called polygon and a mouse called mouse. You check whether the mouse isPressedIn the polygon object - see docs and if it is, you set the polygon p…

Thanks so much, do i need to do this 15 times, or can i just put: if mouse.isPressedIn(Square1, Square2, Square3, etc.) Sorry if these are obvious questions.

You are going to want to keep each conditional separate so that you only set the position for the shape that the mouse is pressed in.

Best to loop through your stimuli and have only one if/then check, and then exit the loop (otherwise, it is easy to end up dragging multiple stimuli as one passes over another). e.g. for stimulus in [square01, square02, square03, etc]: if mouse.isPressedIn(stimulus): stimulus.pos = mou…

That’s great, thank you. And answers what was going to be one of my next queries. Couple of other things I am trying to do…: Any way I can make it so that the squares to be moved can only be dropped/placed on any of the destination squares? I have no idea about PsychoPy data output yet, but all I…

Yes this is all possible. But it is an illustration of how often you can do something amazing with a single line of code (in this case, get real-time interactive animation of a stimulus) but the complexity of the code grows rapidly as you need to add more constraints. I can’t write this code for yo…

This is really helpful, thank you so much. So far I’ve got this, which works on the click and drag but closes the trial as soon as I release the mouse click: if not mouse_down and clicked_square is not None: for dest in [Dest1, Dest2, Dest3, Dest4, Dest5, Dest6, Dest7, Dest8, Dest9, Dest10, Des…

[image] Tom_Olive: closes the trial as soon as I release the mouse click: Is there somewhere in your code where you call core.quit()? Otherwise, ensure that “end routine on press” is unchecked in your mouse component.

[image] Michael: square_locations[square] = square.pos To look up the original locations, we have those stored in a dictionary and so I’m hoping that it would work to use the object to look up its stored location: square.pos = square_locations[square] If not, we might need to change things …

[image] Michael: Is there somewhere in your code where you call core.quit() ? Otherwise, ensure that “end routine on press” is unchecked in your mouse component. As far as I can tell I haven’t got that in my code anywhere and the mouse option isn’t selected. This is the error message in the o…

OK this is an issue with the packages distributed within the PsychoPy application itself. I don’t know what version you are using, but you should watch this thread for progress:
