add text to sphere

[Frank Verberne]

If I understand correctly, avatar2 is not updated in client1, and avatar1 is not updated in client2?

If avatar1 is controlled by client1 and avatar2 is controlled by client2, then you should pass information about the position of avatar1 to client2, and of avatar2 to client1.

I don't understand the part of client2 not visible in client1's environment. At every client side, you should render 2 avatars (avatar1 & avatar2), and also get the information to make them move. Apparently, both avatars are rendered on the server side. So you should use similar code on both clients to make both avatars visible for both clients.

I cannot help you further without more information, e.g. sample code showing the example without the need for extra files/models/setups.

basically, what I have is a multi user environment that consists of 1 server and 2 clients. what I mean by a client is the avatar. and I am using 1 pc as the server and the client.
client 1 will do a specific task (search for radiation source) where as client2 will identify the radiation source.
both clients can exchange messages between them and with the server.

I, as client1, while performing my task and navigating through the environment, I want to c client 2 (avatar2).

this is the code:
just run the server and then the 2 clients. try to control the movement of avatar1 and c if u can find avatar2 while navigating.

hope it is clear now.

thanx

the replay is too long so I had to divided into 2. sorry for that.
