random walk in piazza environment

[maya]

I have posted the wrong code. so plz ignore it. below is the right code.

I managed to simulate an avatar walking randomly. however, I wanted the avatar to pick up the cellphone when he reaches the red sphere. I have the code for that but I did not know how to do it in a simulated way (without pressing any key)

this is the code that I am working on:

import viz
import viznet
import vizinfo
import vizinput
import viztask
import vizact
import vizshape
import vizproximity
import vizmat
viz.go()

viz.go()
viz.MainView.setPosition([0,0.1,0])
viz.setMultiSample(4)
#Increase the Field of View
viz.MainWindow.fov(60)

#avatarRoot = viz.addGroup()
avatarRoot = viz.add('marker.wrl')
cameraLookAtNode = viz.addGroup(parent=avatarRoot, pos=[0, 1.5, 0])
avatar = viz.add('vcc_male.cfg', parent=avatarRoot)
#avatar.state(1)
#viz.collision(viz.ON)



piazza = viz.add('piazza.osgb')
sphere = vizshape.addSphere(radius=0.2)
sphere.setPosition(0,0,20)
sphere.color(viz.RED)

text = viz.addText('radiation source',parent=sphere)
text.setPosition([-0.3,0.3,0])
text.setScale([0.2]*3)
text.color(viz.RED)
text.visible(viz.ON)

text_2D = viz.addText('radiation source area', viz.SCREEN )
text_2D.setPosition(0,0,20)
text_2D.color(viz.RED)
t=text_2D.visible(viz.OFF)

tex = viz.addTexture('logo.jpg')




#maze = viz.add('tankmaze.wrl')
#def onKeyDown(key): 
     #if key == viz.iskeydown ('t' ):
walk1=vizact.walkTo([4,0,0])
walk2=vizact.walkTo([4,0,3])
walk3=vizact.walkTo([7,0,4])

walk4=vizact.walkTo([8.5,0,17])
walk5=vizact.walkTo([10,0,22])
walk6=vizact.walkTo([3,0,23])

#walk=vizact.walkTo([0,0,15])

def changeState() :
    
    #Add the cellphone model
    cell = viz.addChild('phone.3ds')

    #Get the right hand bone of the avatar
    hand = avatar.getBone('Bip01 R Hand')

    #Link the cellphone to the hand
    CellLink = viz.link(hand,cell)

    #Tweek the cellphone link so it fits snuggly in the hand
    CellLink.preTrans( [0.06,-0.08,0.08] )
    CellLink.preEuler( [0,0,180] )
#thick = vizact.method()

walks=vizact.sequence(walk1,walk2, vizact.waittime(1),walk3, vizact.waittime(1),walk4, vizact.waittime(1),walk5,vizact.waittime(1),walk6)
viz.collision(viz.ON)

avatar.addAction(walks)



    #Make the avatar use the cellphone when the 'w' key is pressed
#vizact.onkeydown('w',avatar.execute,15)

#vizact.onkeydown('t',walk)

#Register the callback which to call the 'onKeyDown' function. 
#viz.callback(viz.KEYDOWN_EVENT,onKeyDown) 
	



#Create proximity manager
manager = vizproximity.Manager()

#Add main viewpoint as proximity target
target = vizproximity.Target(avatar)
manager.addTarget(target)

sensor = vizproximity.Sensor( vizproximity.CircleArea(5),source=sphere)

manager.addSensor(sensor)

def EnterProximity(e):
    text_2D.visible(viz.ON)
    quad = viz.addTexQuad()
    quad.setPosition([0,1,20])
    quad.texture(tex) # The quad will now display the tree picture
    spin=vizact.sequence(vizact.waittime(1), vizact.spin(0,1,0,20))
    vizact.addCallback
    quad.addAction(spin)

    
def ExitProximity(e):
    text_2D.visible(viz.OFF)
    

manager.onEnter(sensor,EnterProximity)
manager.onExit(sensor,ExitProximity)
