Article:
Open the file chatHud.cs right after the new
MessageVector(HudMessageVector); add the following code:
// All messages are stored in this HudMessageVector, the actual
// MainChatHud only displays the contents of this vector.
new MessageVector(HudMessageVector);
new MessageVector(HudMessageVectorGlobal);
new MessageVector(HudMessageVectorRoomA);
new MessageVector(HudMessageVectorRoomB);
new MessageVector(HudMessageVectorRoomC);
$LastHudTarget = 0;
$ChatRoom = HudMessageVector;
$ChatSelector = "g";
$ChatText = "GLOBAL:";
// this is a gui elements in chatHud.gui
$ChatHud = ChatHud;
function changeChat(%chatSelector){
$ChatSelector = %chatSelector;
if( %chatSelector $= "g" ){
$ChatRoom = HudMessageVector;
ChatHud.setVisible(true);
ChatRoomA.setVisible(false);
ChatRoomB.setVisible(false);
ChatRoomC.setVisible(false);
$ChatHud = ChatHud;
$ChatText = "GLOBAL:";
}
else if( %chatSelector $= "a" ){
$ChatRoom = HudMessageVectorRoomA;
ChatHud.setVisible(false);
ChatRoomA.setVisible(true);
ChatRoomB.setVisible(false);
ChatRoomC.setVisible(false);
$ChatHud = ChatRoomA;
$ChatText = "ROOM A:";
}
else if( %chatSelector $= "b" ){
$ChatRoom = HudMessageVectorRoomB;
ChatHud.setVisible(false);
ChatRoomA.setVisible(false);
ChatRoomB.setVisible(true);
ChatRoomC.setVisible(false);
$ChatHud = ChatRoomB;
$ChatText = "ROOM B:";
}
else if( %chatSelector $= "c" ){
$ChatRoom = HudMessageVectorRoomC;
ChatHud.setVisible(false);
ChatRoomA.setVisible(false);
ChatRoomB.setVisible(false);
ChatRoomC.setVisible(true);
$ChatHud = ChatRoomC;
$ChatText = "ROOM C:";
}
}
In this same file ChatHud.cs make the following changes:
Change
all the HudMessageVector with $ChatRoom or $HudMessageVector or any
variable name you feel comfortable using and all the ChatHud with
$ChatHud in the whole file, this will enable us to instead of
Using a single object we will use a "pointer" (the global variable) to the object so we can change it at any time.
Example:
while( !chatPageDown.isVisible() && HudMessageVector.getNumLines() &&
(HudMessageVector.getNumLines() >= $pref::HudMessageLogSize))
Should look like this.
while( !chatPageDown.isVisible() && $ChatRoom.getNumLines() && ($ChatRoom.getNumLines()
>= $pref::HudMessageLogSize))
In the function onChatMessage add an extra parameter %chatWindow
function onChatMessage(%message, %voice, %pitch, %chatWindow){...}
and replace the whole if statement
// Chat goes to the chat HUD.
if (getWordCount(%message)) {...}
with
// Chat goes to the chat HUD.
if (getWordCount(%message)) {
// save the current variables
// to keep using them later
%tempChatHud = $ChatHud;
%tempHudMessageVect = $ChatRoom;
if( %chatWindow $= "g" ){
$ChatRoom = HudMessageVector;
$ChatHud = ChatHud;
}
else if( %chatWindow $= "a" ){
$ChatRoom = HudMessageVectorRoomA;
$ChatHud = ChatRoomA;
}
else if( %chatWindow $= "b" ){
$ChatRoom = HudMessageVectorRoomB;
$ChatHud = ChatRoomB;
}
else if( %chatWindow $= "c" ){
$ChatRoom = HudMessageVectorRoomC;
$ChatHud = ChatRoomC;
}
$ChatHud.addLine(%message);
$ChatHud = %tempChatHud;
$ChatRoom = %tempHudMessageVect;
}
Add at the end of the file. these are copies of ChatHud you will have to add one for work
For each chatRoomX that you have

}
Now add 4 buttons and 3 GuiMessageVectorCtrl in chatHud.gui this is not the whole code,
Just the part that adds the buttons and the GuiMessageVectorCtrl
...

};
...
In the file messageHud.cs in the function
function MessageHud_Edit::eval(%this){...}
around line 87 add one parameter to the commandToServer
if(MessageHud.isTeamMsg)
commandToServer('teamMessageSent', %text);
else
******* commandToServer('messageSent', %text, $ChatSelector);
In the file common/client/message.cs change the function clientCmdChatMessage with this
function clientCmdChatMessage(%sender, %voice, %pitch, %msgString, %a1, %a2, %a3, %a4,
%a5, %a6, %a7, %a8, %a9, %a10)
{
onChatMessage(detag(%msgString), %voice, %pitch, %a3);
}
Ok
so we are done with the client side, at this point if you start your
game you should see a chat window with four buttons on the side, if you
choose any of these buttons the screen should change. we do not have to
mod the server because thankfuly we are using one of the extra
paramenters that the messaging system has available :) and there for
the parameter of which chat room the message should go to has been
passed all the way back to each client that recieves the message and
has been taken care of in clientCmdChatMessage.
If you want to know where the messages are handled in the server go to
common/server/commands.cs and look at the function serverCmdMessageSent(%client, %text,
%chatSelector){...}
Hope this will help someone.
