Hey all,
I have made a function controller to control position, and am trying
to get it to change the position of a texture stimulus. The controller
works fine, because it will move other objects as it is supposed to.
When I load a .jpg file into the TextureStimulus, it displays in the
original position specify, but does not appear to update its position
after that (ie it never moves). Any suggestions?

A few suggestions:
1) Are you sure that the units you're using are properly scaled
according to your viewport (and its projection)?
2) Are you sure that the FunctionController is actually being called?
(Add a print statement and make sure it does print something.)
3) Modify the draw() method of the TextureStimulus class to print
self.parameters.position to make sure it's changing the way you expect.
Or, to stay away from the source, do this:
class DebugTextureStimulus( TextureStimulus ):
def draw(self, *args,**kw):
print self.parameters.position
TextureStimulus.draw(*(self,)+args,**kw)
And make an instance of DebugTextureStimulus.
Post some code if these don't help.
Cheers!
Andrew
