Rotating images

[Amy]

I'm wondering if anyone has experience of rotating images in the Builder?

I am trying to design a task with a spinning wheel. I have read the documentation http://www.psychopy.org/builder/components/patch.html although I can't find the patch stim component in the builder! so I'm struggling to get started.

Any help would be much appreciated

The Patch stimulus has been separated into a Grating and an Image
stimulus that cover the same functionality. Both the Image and Grating
(and nearly all other stimuli) have a parameter `orientation` and if you
set that to change every frame you can generate a rotating stimulus.

best wishes,
Jon

Great - thank you for your fast reply.

So if i have a list of images in an experiment and each one should spin (when some key is pressed) then I set the Ori to change every frame for

$imageFile2

So what kind of code would I add to each frame in order to control the number of spins or degrees spun?

Thank you in advance

All builder scripts have a variable called t that represents time from start of the routine. You could set your orientation to be
    $t*5
After one second your orientation will be 5 deg, after 2 s it will be 10deg etc...

That worked great! Is there a way to make the onset of the stimulus (and thus spinning) dependent on a particular mouse or key press?
