Clicking experiment, little issue with a time max response...
(Sorry it's a bit unreadable but I couldn't code quoting the whole..)
Hi,
So that's the first experience that I try to create, I decided to use OpenSesame but I get some issues, if you have any idea about how to fix it that would be really great. I think I need to say it's the first time I use python so may be the error is really easy to solve but I could not do anything without any experience and I didn't found helpful answers in same issues on internet..
The experiment consists in making one cross appears -click on it when it becomes green-, then a fix dot appears -click on it-, and a last one appears -click on it again-, positions of these events are variables.
And I would want an error message when the subject's click is misplaced or when he doesn't click fast enough, the first one is easy but I'm not able to elaborate the second..
The first try is with this code:
def go():
first = True
second = False
third = False
ok = False
rt = clock.time()
while first:
my_canvas.image(red_cross, x=var.depart, y=0)
my_mouse.show_cursor(show=True)
my_canvas.show()
clock.sleep(2000)
my_canvas.image(green_cross, x=var.depart, y=0)
my_canvas.show()
button, position, timestamp = my_mouse.get_click(timeout=2000, visible=True)
x, y = position
if x < var.depart-erreur or x > var.depart+erreur and y < 0-erreur or y > 0+erreur:
my_canvas.clear()
my_canvas.image(precis)
my_canvas.show()
clock.sleep(1000)
my_canvas.clear()
break
if x > var.depart-erreur and x < var.depart+erreur and y > 0-erreur and y < 0+erreur:
global rt1
rt1 = clock.time() - rt
my_canvas.clear()
first = False
second = True
else:
my_canvas.clear()
my_canvas.image(rapide)
my_canvas.show()
clock.sleep(2000)
my_canvas.clear()
break
while second:
my_canvas.fixdot(x=0, y=var.hauteur)
my_canvas.show()
button, position, timestamp = my_mouse.get_click(timeout=2000, visible=True)
x, y = position
if x < 0-erreur or x > 0+erreur and y < var.hauteur-erreur or y > var.hauteur+erreur:
my_canvas.clear()
my_canvas.image(precis)
my_canvas.show()
clock.sleep(1000)
my_canvas.clear()
break
if x > 0-erreur and x < 0+erreur and y > var.hauteur-erreur and y < var.hauteur+erreur:
global rt2
rt2 = clock.timme() - rt1
my_canvas.fixdot(color="yellow", x=0, y=var.hauteur)
my_canvas.show()
clock.sleep(50)
my_canvas.clear()
second = False
third = True
else:
my_canvas.clear()
my_canvas.image(rapide)
my_canvas.show()
clock.sleep(2000)
my_canvas.clear()
break
while third:
my_canvas.fixdot(x=var.sens, y=var.hauteur)
my_canvas.show()
button, position, timestamp = my_mouse.get_click(timeout=2000, visible=True)
x, y = position
if x < var.sens-erreur or x > var.sens+erreur and y < var.hauteur-erreur or y > var.hauteur+erreur:
my_canvas.clear()
my_canvas.image(precis)
my_canvas.show()
clock.sleep(1000)
my_canvas.clear()
break
if x > var.sens-erreur and x < var.sens+erreur and y > var.hauteur-erreur and y < var.hauteur+erreur:
global rt3
rt3 = clock.time() - rt2
global ok
ok = True
my_canvas.fixdot(color="yellow", x=var.sens, y=var.hauteur)
my_canvas.show()
clock.sleep(50)
my_canvas.clear()
my_canvas.image(white_screen)
my_canvas.show()
clock.sleep(1000)
my_canvas.clear()
third = False
else:
my_canvas.clear()
my_canvas.image(rapide)
my_canvas.show()
clock.sleep(2000)
my_canvas.clear()
break
while 1:
go()
if ok:
break
With this one the error is in the 'else', when I wait for two seconds to click on the cross or on the fixdot, pygame crashes and the ErrorType message is "'NoneType' object is not iterable ".. I tried to write it in other ways (like "if button == None:") but with that type of construction the problem keep appearing.
So I tried an other type of construction and I get an another issue..

The code is may be more complex for what it is but it's cause I tried many options, without any working.. So here the time max is not a problem but the thing is that the first click activates the command on the 'def second' so when the first fix dot appears after the click on the green cross, it automatically make like the subject hadn't clicked on the fixdot and then error of misclicking.
I hope I'm clear and that may be one of you has a simple idea to get it solved ?
Many thanks,
Nicolas

Hi Nicolas,
Sorry, but this is really a lot of code that seems to make sense somewhat. However, without having a better description of the desired behaviour it is very difficult to help you debugging. Would you mind elaborating a little more? Maybe you could also upload the experiment, so I could have a look?
Thanks,
Eduard
Actually to just present clearly my problem, trying to allow mouse clicking detection, I used that function:
And just using these four lines, the "'NoneType' object is not iterable" error appears..
Are you sure you used the example as above? The following typo in line 3 would result in the error you mention:
if button in None:Here,
inshould have beenis.If you did copy it without error, then try the following instead of line 2:
button, pos, timestamp = my_mouse.get_click(timeout=5000)
