[visionegg] Re: fixation viewport

Yes, that would be nice, but how about answering my question?

Perhaps patience is a virtue you need to learn. I'm sorry, but hounding a list for answers to programming questions when you haven't (or at least shown no evidence of) examined the available demo code is rude, and I don't think the person who replied to your initial post should be lambasted for offering that suggestion.

Now, look at the following code snippet (which will not work on its own, as I have removed irrelevant code for your problem).

I have created a stimulus (in this case it is referred to by texture), and a fixation class.

I create 2 viewports [f and p]. f is the viewport with only the fixation and p is with fixation and the stimulus. and present them in order using

f.go
p.go


Add this concept to your existing code base and play with it.

Do I
have to search all over the python world to find this too?

Showing the list that you have initially attempted to solve your problem before asking seemingly random questions is not a bad starting point. Searching the demo direectory of the VisionEgg is a good starting point, and not as large as the entire python world.

The MatLab news list for example wouldn't even respond to your initial posts as they are extremely harsh on people who are seemingly trying to get their code written in piecemeal fashion by asking questions after question.

variable/parameter to set and then just set it.  However, it was not
solved in 5 minutes and I'm not sure what the next step is

Submit the code that you have then, and perhaps responses will come better.

I hope that the code I have attached works out, good luck with it.

Hi, Andrew and all,

It might be a good idea to add a section to the VisionEgg web site with actual 
implemented studies (contributed by volunteers), in addition to the standard 
demos.  This would aid with some of these questions, in addition to lowering 
the bar for newbies wanting to try out VisionEgg.  At the very least, the 
addition of code templates for common psychophysical study-types, such as RSVP 
or multiple-object tracking, might be useful.

As a research programmer, I have the luxury of dedicating myself to scowering 
the related python newgroups and lists and trying things out on my own, but 
many of my psychologist colleagues don't have either the time or programming 
knowledge to do this... in effect, the very reason tools like VisionEgg exist 
(to make psychophysical studies easier to implement!)

I know I've had many of these same questions when I first started coding in 
python/VisionEgg, and I learned as everybody else does... by example.

Hi,

the construct

screen = get_default_screen()

creates a gray screen.  The reference documentation for the screen
class indicates that it has a bgcolor parameter.  I've tried a number
of ways to set it, without success.  How do we set this parameter?  I
want, bgcolor = (0.0, 0.0, 0.0), rather than the default gray.

Best, Darren
