vizact.ontimer problems?

Hi all,
I have a program that is supposed to give stimuli to a subject and constantly monitor a button for feedback from the subject. The button is not keyboard, but connected by adding a .dls file. The method to check the button, however, never runs. I had an older version that used a callback to a timer_event perfectly, and I don't know why it won't work now. Heres the code below that I think is relevant...

def giveStimuli():

...

def checkButton():

...

vizact.ontimer(.001,checkButton)
starttimer(0,.001,FOREVER)
viztask.schedule(giveStimuli())

checkButton should be getting called. try

Code:

def checkButton():

        print "in checkButton"



vizact.ontimer(0,checkButton)

this following line has incorrect syntax and you don't need it here for calling checkButton since you are using vizact.ontimer

Code:

starttimer(0,.001,FOREVER)

if you were using a callback with it it would be

Code:

viz.starttimer(0,0,viz.FOREVER)

one other thing is that your timer will not run every .001 seconds. It will only get called as fast as your framerate. If you use 0 for the rate the timer will be called every frame.
