random walk in piazza environment

[maya]

thanks it worked.

I have another question.

I replaced the avatar with the steve module and I added the move to action to the module, but I got this error:

player_matrix.aaddAction(walks)
AttributeError: 'Transform' object has no attribute 'addAction'

how can I simulate the movement of the steve as I did with the avatar in the code provided above?

thanks.

You cannot add an action to a matrix. You can add an action to an avatar. Look carefully how you named the 3D-model of steve, and add the action to that model. That should solve your problem.

And there was a type in your addaction command, it was spelled aaddaction.

thanks it worked. however, I want to c what the steve module sees infront of him (what he is looking at).

I want it to be in this way as reflected in the upper right view:
this is the code:

import viz
import viznet
import vizinfo
import vizinput
import viztask
import vizact
import vizshape
import vizproximity
import vizmat
import steve

viz.setMultiSample(4)
viz.fov(60)
viz.go()

# Use the steve module to represent the other user.
# You will actually have no representation of yourself on your own monitor.
player_matrix = viz.Matrix()
avatar = steve.Steve()
avatar.setTracker(player_matrix)

# Add the world
maze = viz.addChild('piazza.osgb')

#Use a prompt to ask the user the network name of the other computer.
target_machine = vizinput.input('Enter the name of the other machine').upper()

#Add a mailbox from which to send messages. This is your outbox.
target_mailbox = viz.addNetwork(target_machine) 

def sendPosition():

     #Retrieve current transform of viewpoint
     mat = viz.MainView.getMatrix()

     #Send position/rotation to target network object
     target_mailbox.send(action=updatePlayer, quat=mat.getQuat(), pos=mat.getPosition())

# Start a timer that sends out data over the network every frame
vizact.ontimer(0,sendPosition)

def updatePlayer(e):
     player_matrix.setPosition(e.pos)
     player_matrix.setQuat(e.quat)

# Listens for any incomming messages
def onNetwork(e):
     if e.sender.upper() == target_machine:
         e.action(e)

# Register network to listen from incomming messages
viz.callback(viz.NETWORK_EVENT, onNetwork)

# Create a new window in the upper left corner
UpperLeftWindow = viz.addWindow(pos=(0,1.0),size=(0.5,0.5))
UpperLeftWindow.visible(0,viz.SCREEN)

#Create a new window in the upper right corner
UpperRightWindow = viz.addWindow(pos=(0.5,1.0),size=(0.5,0.5))
UpperRightWindow.visible(0,viz.SCREEN)

# Create a new viewpoint
BirdView = viz.addView()

#Attach the bird's eye view to the upper left window
UpperLeftWindow.setView(BirdView)

#Move the view above the center of the room
BirdView.setPosition([0,25,0])

#Rotate the view so that it looks down
BirdView.setEuler([0,90,0])

#Create another viewpoint
RearView = viz.addView()

#Attach the rear view to the upper right window
UpperRightWindow.setView(RearView)

#Increase the field-of-view for both windows
UpperLeftWindow.fov(70)
UpperRightWindow.fov(60)

#Add an arrow marker to bird's eye view window to represent our current position/orientation
arrow = viz.addTexQuad(parent=viz.ORTHO,scene=UpperLeftWindow,size=20)
arrow.texture(viz.add('arrow.tif'))

def UpdateViews():

	#Get the current head orientation and position
	yaw,pitch,roll = player_matrix.getEuler()
	pos = player_matrix.getPosition()

	#Move the rear view to the current position
	RearView.setPosition(pos)

	#Rotate the rear view so that it faces behind us
	RearView.setEuler([yaw,0,0])

	#Move arrow to our current location
	x,y,z = UpperLeftWindow.worldToScreen(pos,mode=viz.WINDOW_PIXELS)
	arrow.setPosition([x,y,0])
	arrow.setEuler([0,0,-yaw])

vizact.ontimer(0,UpdateViews)

# Turn on collision detection so we can't go through walls
#viz.collision(viz.ON)
walk1=vizact.moveTo([4,0,0])

walk2=vizact.moveTo([4,0,3])
walk3=vizact.moveTo([7,0,4])

walk4=vizact.moveTo([8.5,0,17])
walk5=vizact.moveTo([10,0,22])
walk6=vizact.moveTo([3,0,23])
walks=vizact.sequence(walk1,walk2, vizact.waittime(1),walk3, vizact.waittime(1),walk4, vizact.waittime(1),walk5,vizact.waittime(1),walk6)
#avatar.addAction(walks)


#avatar.addAction(vizact.walkTo([0,0,7]))

btw, I commented the "add action" .
thanx
