Server lost check
i started checking the tutorials,now i'm working on the client/server tutorial and made several modifications to it,now i wanted to make a server lost check,so if the server is gone to eather say connection lost of clear all neighbors,is there such feature to check for the server in the code or i need to do a ping/pong check

RE: Server lost check
you can put in your Update() state on client side:
Code:
if(connection.state() == CONNECT_INVALID)
{
Gui.msgBox("Connection lost", "Connection lost");
}
and on server side to ~Client() (destructor) you can put anything to send to neighbors

RE: Server lost check
well i used ur code,first i got the msg right away cause i made the server ip to be picked from a textline and needed to use the login button,then i made a bool in the login if(connection.state() == CONNECT_INVALID &&connected() == true) it didn't work, made the bool to be default == false and on login changed to true,but it dosn't work

RE: Server lost check
you create Connection connection in every update, it should be created once and before everything
put Server into update check
