[open] How to draw a set of dots for an Android experiment?

MayMay
edited October 2015 in OpenSesame

Hi,
I'm looking for a way to draw a set of dots in the sketchpad for an experiment to run on Android. I need to do it in a way that I can manipulate the number of dots as a variable. I've been reading this can generally be done by importing the ElementArrayStim function from PsychoPy, but is it possible to do this using the Droid back-end?
Also, would it be possible to control more advanced features such as the total area or circumference length of all dots?
Any advice will be greatly appreciated. Thanks!

    No, PsychoPy doesn't work on Android. However, you could use the xy_random() function (OpenSesame 3.0) to achieve more-or-less the same thing. Let's assume that you have an experimental variable called ndots, then the following script will draw this number of non-overlapping circle:

    c = canvas()
for x, y in xy_random(n=var.ndots, width=100, height=100, min_dist=20):
    c.circle(x, y, r=10)
c.show()
