Timer cycling correctly?

[JMOwens]

Hi all,
I have a timer running my program at 1/60 second, as indicated below:

def masterLoop(num):
.
[main program here]
.
viz.callback(viz.TIMER_EVENT,masterLoop)
viz.starttimer(0,1/60,viz.FOREVER)

However, when I insert a viz.elapsed() into the callback, it returns values of roughly 0.004. I may be misunderstanding the function, but shouldn't it be returning 0.017, which is 1/60? Sorry if this is a dumb question, but it's really important that this timer is cycling correctly. Thanks for your help!

In Python, the result of dividing two integers will be another integer. Try the following in the interactive interpreter:>>> 1/60
0
>>> 1/60.0
0.016666666666666666
>>> 1.0/60
0.016666666666666666So your code is setting a timer to expire every 0 seconds, which will be every frame. You will need to do the following instead:viz.starttimer(0,1/60.0,viz.FOREVER)

Oh man, thanks a lot - I knew that, but forgot it in the context of a fraction! Doh. Thanks again.
