Catching outputs from functions called in vizact.ontimer()

How can I capture the outputs from a function called using the vizact.ontimer() function? I understand that I need to define the name of the function I want to call, and pass any arguments in to the function following that; eg:

Code:

vizact.ontimer(0,myFunction,input)

...But I don't know how to get the outputs of myFunction. How do I do this?

Can you explain what you are trying to accomplish with a timer function and the output you're expecting?

At every screen refresh, I need to manipulate a quad based on the position of a couple of trackable (from motion capture) rigid bodies. I need to pass some variables back into 'myFunction' that are output from 'myFunction' on each occurrence. These are a few ints and bools.

I'd recommend creating a class to update the quad and to store variables from each update. Here is a simple outline of what I am referring to:

Code:

import vizact



class QuadManipulator(object):

        def __init__(self, input):



                # Save input

                self.input = input



                # Initialize variables here

                self.some_int = 0

                self.some_bool = False



                # Call our method every frame

                vizact.ontimer(0, self.myFunction)



        def myFunction(self):



                # Compute some stuff and update quad



                # Update some variables

                self.some_int = 2

                self.some_bool = True



# Create instance of our class

q = QuadManipulator('input')
