Code component for click and drag responses

Builder
1

OS Mac Catalina 10.15.6
PsychoPy version 2020.2.3:
Standard Standalone? (y) Yes

What are you trying to achieve?:

I am aiming to create an experiment that allows participants to drag and drop a net stimulus (image) into the perceived coin (circle polygon) location.

What did you try to make it work?:

I used a similar discourse thread to work on a code component in builder:

This is the code I used to get a click and drag component for my image (adapted from Oli’s reply in order to refer to my image)

#Begin routine
``dynPos = (0,0) # dynamic position variable

#Each frame
while mouse.isPressedIn(netImage): dynPos = mouse.getPos()
Net3

What specifically went wrong when you tried that?:

2020-09-04 10:02:33.429 python[99773:1934702] ApplePersistenceIgnoreState: Existing state will not be touched. New state will be written to (null)
Traceback (most recent call last):
File “/Users/lucymckeown/Documents/coinExperiment/showCoin_lastrun.py”, line 230, in
if obj.contains(mouse):
AttributeError: ‘str’ object has no attribute ‘contains’

Experiment ended.

The experiment runs through and the the mouse co-ordinates are achieved but with no click and drag functionality

Please see my experiment file and conditions file attached (Net3.png is the image)

Hi Lucy,

Another useful starting point might be to try adapting the demo under demos>dragAndDrop ? :slight_smile: this should do what you want after a bit of editing.
