WorldViz User Forum - Scheduling action at different timings using time.time()

Hello!

I am trying to schedule an action (a beep sound) in Vizard. However, I want the beep to happen at certain timings since onset of the trial.

What I have so far gives me (for example, after running it once) a list of times "times: [ 1.89229142 5.2610474 9.86058804 11.43137033 13.87078666]" and is playing the beep at what seems to be varying intervals and prints out the elements of the above mentioned list. It's just that it's not actually using these elements as seconds/timings at which to play.

My question is: How do I make Python know that these are not just numbers, but timings since onset of the function/trial? Probably I am supposed to use time.time() somewhere, but I am just not sure about the logic of how to get there.

Code:

import time

import numpy as np

import viztask                                              





### Start Vizard ### 

viz.go()





### Cue sound ###

cue = viz.addAudio('cues\dong.wav') 

cueDuration = cue.getDuration() 



### Timings ###



def uniform_min_range(a, b, n, min_dist):

    while True:

        times = np.random.uniform(a, b, size=n)

        np.sort(times)

        if np.all(np.diff(times) >= min_dist):

            return times



def timings():

    global times

    times = uniform_min_range(0, 20, 5, 1.0)

    print "times: ", times





def main():

    global times

    timesIndex =0

    for x in range(len(times)):

        cuetime = times[timesIndex]

        cue.play()

        print 'cue'

        print cuetime

        yield viztask.waitTime(cueDuration + cuetime)

        cue.stop()

        timesIndex = timesIndex + 1
