Timer Question

I have a program that I want to run for 10 minutes. In those 10 minutes I want it to check for the time. For the first 3 minutes I want it to run one function. After the 3 minutes expires I want it to start another function for 4 minutes. When that expires I want it to run another function for the remaining 3 minutes.

Do I use a starttimer and have the starttimer equal something and put the 3 functions in a loop so it keeps checking the time?

Im looking for a good way to write this.



def function1():


//end of function 1

def function2():


//end of function 2

def function3():


//end of function 3

Here is an example that uses the viztask module to control the timing of the 3 different functions:

import viz
import vizact
import viztask

def func1():
def func2():
def func3():

def MainTask():
        #Run func1 for 3 minutes
        timer = vizact.ontimer(0,func1)
        yield viztask.waitTime(180)
        #Run func2 for 4 minutes
        timer = vizact.ontimer(0,func2)
        yield viztask.waitTime(240)
        #Run func3 for 3 minutes
        timer = vizact.ontimer(0,func3)
        yield viztask.waitTime(180)
        #Quit script
viztask.schedule( MainTask() )

Ok thanks for that... If I wanted to do it via pressing keys and not a timer how would I do that. I got it to work but I have trouble after I go on to the next function... I can never go backwards.


I press 'a' to initiate def func1():

I then press 's' to iniatiate def func2():

If I press 'a' again I get an error. I assume I need a ontimer or something but I have trouble trying to figure that out.

Any insight would be much appreciated

If you just want to call functions based on keypresses use something like


vizact.onkeydown('a', func1)
vizact.onkeydown('s', func2)

All times are GMT -7. The time now is 04:01 AM.
