Random Dot Kinematogram
Hi there!
I was wondering whether there is the possibility of creating a random dot kinematogram in the background of, e.g., a search display in OpenSesame. Since PsychoPy has this functionality, I guess this can also be used in OpenSesame. However, unfortunately, I have no clue how to implement that.
For example, is there a way to specify in an inline script, that a specific canvas (in my case: "Searchdisplay") should contain random dots that move from A to B with the speed X?
Thanks a lot in advance for any suggestions!
Best,
Christian

Hi Christian,
As far as I know, you can't implement a slider directly with Opensesame. Psychopy however is quite well able to do it. So, you could import psychopy in an inline_script and draw the cloud like that, but probably this would open another window, because you probably can't make psychopy draw on Opensesame's canvas.
If you need help implementing it in Psychopy, let me know. I have recently done it.
Good luck,
Eduard
Hi Eduard,
Thanks a lot for your response! What a pity that this probably doesn't (yet? ;)) work in OpenSesame.
Thank you a lot for your offer, too. If it comes to it, I will contact you.

Yeah it is to do, with how Opensesame organizes the drawing aspect of a canvas (prepare-run-strategy). This frame-wise updating that is typical for RDK makes it a little tricky to apply the prepare-run strategy to RDKs.
