I’m new to Psychopy coder and I need some help.
I’d like to create a stimulus like this example here:
Basically it’s a central field full of dots moving in circles at a slow speed, and a peripheral field of dots moving in circles at a fast speed.
I have been trying my best using the ‘dotStim’ object but it has the following limitations:
- The dots move in a straight line or a random walk, not in a nice circle
- The dots in the central field are ‘cut’ when they reach the edge of the central field - in the example they never reach the edge of the central field and thus do not get cut.
Can anyone give me tips/suggestions on which elements to use and how to set them up for a stimulus that is more like the example?
Thanks for your help!
