Proximity Manager - How to implement delay

[Jeff]

Use the vizproximity.waitEnter command within a task function:

import viztask

def proximityTask():

	yield vizproximity.waitEnter(SensorIndexFinger)
	print 'entered sensor'
	yield viztask.waitTime(2)
	print 'two seconds elapsed'

viztask.schedule(proximityTask())

Dear Jeff,

thank you for the help, this seems like the way to go! But I have some problems with it:

I noticed that adding the line

viztask.schedule(proximityTask())

makes the event happen only once, upon entering the sensor for the first time.

My question would be how do I make it happen everytime, like it was the case when I used

manager.onEnter(SensorIndexFinger,EnterProximity_IndexFinger)

I tried the following (somehow adding the function that specifies the delay to the manager):

SensorIndexFinger = vizproximity.Sensor(vizproximity.Box([0.03,0.03,0.03],center=[0,0,0]),IndexFinger) 
manager.addSensor(SensorIndexFinger)

def proximityTask():
        global handstate
	yield vizproximity.waitEnter(SensorIndexFinger)
	print 'entered sensor'
	yield viztask.waitTime(2)
	print 'two seconds elapsed'
        handstate = 1
        print 'change hand'

def EnterProximity_IndexFinger(e): # decide what happens on sensor entry
	global handstate
	e.sensor == SensorIndexFinger 
	print "activate proximityTask"
manager.onEnter(SensorIndexFinger,proximityTask())

But I get an error "TypeError: 'generator' object is not callable."

I would be very happy to hear if you had any suggestions on how to call the action (with delay) every time the sensor was entered, as I can't seem to find a way to implement it

You can add a loop inside the task function:

def proximityTask():

	while True:
		yield vizproximity.waitEnter(SensorIndexFinger)
		print 'entered sensor'
		yield viztask.waitTime(2)
		print 'two seconds elapsed'

viztask.schedule(proximityTask())

Thank you so much, Jeff, this works perfectly!
