Multi User Environment
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: Code:
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.cfg'] 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,onStartClient) def onStopClient(e): print '** Client left:',e.sender viznet.server.send(CLIENT_DISCONNECTED,client=e.sender) # 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,onStopClient) 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 def onKeyDown(key): global talking if key == 'y' and not talking: # Start talking mode talking = True input.message('> _') input.visible(1) elif key == viz.KEY_ESCAPE and talking: # Exit talking mode talking = False input.visible(0) return True elif talking and key == viz.KEY_RETURN: # Send message talking = False viznet.server.send(CHAT,client='SERVER',chat=input.getMessage()[2:-1]) input.visible(0) # Update display with our message updateChat('SERVER'+': '+input.getMessage()[2:-1]) elif talking and key == viz.KEY_BACKSPACE: # Delete a character if len(input.getMessage()) > 3: input.message(input.getMessage()[:-2]+'_') elif len(key) > 1: # Handle special keys return False elif talking and 32 <= ord(key) <= 126: # Input message input.message(input.getMessage()[:-1]+key+'_') viz.callback(viz.KEYDOWN_EVENT,onKeyDown,priority=-6) Code:
import viz import viznet import vizinfo viz.go() viz.clearcolor(.2,.2,.4) maze = viz.add('tankmaze.wrl') objects = {} SEND_UPDATE_TIMER = 1 UPDATE = viznet.id('update') CLIENT_DISCONNECTED = viznet.id('client_disconnected') CHAT = viznet.id('chat') SERVER_NAME=viz.input('Enter Server Name') while not viznet.client.connect(SERVER_NAME,port_in=14951,port_out=14950): if viz.ask('Could not connect to ' + SERVER_NAME + ' would you like to try another?'): SERVER_NAME=viz.input('Enter Server Name') else: viz.quit() break objectList = ['duck.wrl','logo.wrl','male.cfg','vcc_female.cfg'] obj_choice=viz.choose('Connected.

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

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 |

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