Timer Actions problem

[whj]

Oh!!! I always thought the second argument of vizact.ontimer2 was the number of times to active the timer. Sorry about that. I should set it to 0. I'll correct it and see what happened....

Thanks a lot!

Thank you, Jeff. It works!

Now I make a little change on the reset part. I would like to reset the object (duck or ball) right before being played. But I got the following error:

Traceback (most recent call last):
File "C:\Program Files\WorldViz\Vizard30/python\vizact.py", line 2980, in __ontimer
val = event.call()
File "C:\Program Files\WorldViz\Vizard30/python\vizact.py", line 2803, in _callStatic
return self.func(*self.args,**self.kwargs)
TypeError: 'NoneType' object is not callable


Could you please help me find the problem again? Thanks!

The error is in this line

vizact.ontimer2(wait, 0, reset(object[x]))

You need to pass the argument to your function like this

vizact.ontimer2(wait, 0, reset, object[x])

Thank you so much for your help, especially at weekend.
