Multi User Environment

[moneim230]

i want to create a multi user environment between several users that allows them to chat and watch the same environment together.
i tried this code from vizard reference but it did not work!
Server:
import viz
import viznet
viz.go()
viz.clearcolor(.2,.2,.4)

viz.MainView.setPosition(70,45,-60)
viz.MainView.lookat(0,0,10)

objectList = ['duck.wrl','logo.wrl','vcc_male.cfg','vcc_female.c fg']
maze = viz.add('tankmaze.wrl')
objects = {}

UPDATE = viznet.id('update')
CLIENT_DISCONNECTED = viznet.id('client_disconnected')
CHAT = viznet.id('chat')

viznet.server.start(port_in=14950,port_out=14951)

def onStartClient(e):
print '** Client joined:',e.sender
viz.callback(viznet.CLIENT_CONNECT_EVENT,onStartCl ient)

def onStopClient(e):
print '** Client left:',e.sender
viznet.server.send(CLIENT_DISCONNECTED,client=e.se nder) # Alert other clients
objects[e.sender].remove() # Remove object from our map
del objects[e.sender] # Delete user from array
viz.callback(viznet.CLIENT_DISCONNECT_EVENT,onStop Client)

def update(e):
try:
objects[e.sender].setPosition(e.pos)
objects[e.sender].setEuler(e.ori)
except KeyError: # If key doesn't exist add the user's object
objects[e.sender] = viz.add(objectList[e.object],scale=[2,2,2],pos=e.pos,euler=e.ori)
objects[e.sender].tooltip = e.sender # Sets the tool tip for this object
viz.callback(UPDATE,update)

# Tool Tip
import viztip
tth = viztip.ToolTip()
tth.start()
tth.setDelay(0)

# Chat Stuff
def updateChat(msg): # Function to update the chat display
text.message('\n'.join(text.getMessage().split('\n ')[1:])+'\n'+msg)

text = viz.addText('\n\n\n\n',viz.SCREEN) # Add to screen
text.alignment(viz.TEXT_LEFT_BOTTOM)
text.fontSize(25)
text.setPosition(.05,.08)

input = viz.addText('> _',viz.SCREEN) # Add to screen
input.fontSize(25);
input.setPosition(.032,.05)
input.visible(0) # We only want visible when in type mode

def onChat(e): # Update the message display
updateChat(e.client+': '+e.chat)
viz.callback(CHAT,onChat)

talking = False

any suggestions?

Are the machines able to ping each other? Have you tried disabling any firewalls and virus scanners to see if that makes a difference?

yes they ping each other and the firewalls are disabled.
i run the server code first then when i run the client code and write the server name it says "connected" and i select the character but the server does not see the client character navigating.
i also tried 2 clients connected to a server but they don't see each other and the server can't see them

chatting works too
the problem is that the characters don't appear

Sorry about that, there was missing code in the documentation. If you add the following to the client script does it work for you?
def sendUpdate():
ori= viz.MainView.getEuler()
pos = viz.MainView.getPosition()
viznet.client.sendAll(UPDATE,client=viz.getCompute rName(),object=obj_choice,pos=pos,ori=ori)
vizact.ontimer(.05,sendUpdate)

thx Jeff it works now.
i hope vizard 4.0 documentation will get updated with this missing code.
