URL of experiment:
PsychoPy version is 3.0.6, and Mac OS 10.14.4.
I used Google chrome73.0.3683.103
Description of the problem:
I tried to move a rectangle from left to right in a web browser.
My sample program was very simple; I set a polygon component and changed the shape to “rectangle” and the position to (t, 0) and “set every frame”.
This program ran successfully in my computer, but it did not run online.
I saw an error message as follows:
Unfortunately we encountered an error:
when converting an object to its numerical form
unable to convert: undefined to a number.
Try to run the experiment again. If the error persists, contact the experimenter.
Is it possible to move a rectangle online?
