Made that myself.
Actualy, now that I think of it. That wont work... Let me explain exactly what I want.
I make a server, my "clientNumber" is 0(I'm the host). Someone else joins, they have a "client number" of 1. Yet another player joins, he has a "client number" of 2. Then the guy with the client number of 1 leaves the server. Now the guy with the client number of 2 gets "shifted down" to 1. This is what I was trying to do, but now that I think of it...I think theres a better way to accomplish what I'm trying to do.
If any of you have ever RP-ed, you may know that trying to pick out the message that the person that your RP-ing with could be easier...So I'm making a mod s everyone talks in one color. Now that I think of it, I think it would be better to assign a variable to the client when he joins my server. A variable that would be used to determine the color they talk in(a hex number). That way, if your used to "so-and-so" talking in blue and someone leaves and the numbers get shifted, the color wont change.(if the client has their own "color" variable). I appreciate you guys posting to help me by the way ^_^. Do you think this is a better way of doing it?
