Retrieving players' data when they join a server

[UTPe]

Hi,
I would need to know how to retrieve players' basic data when they join a server.
I'm using the modifyLogin function of Mutator class.
By using playerName = Level.Game.ParseOption(Options, "Name") it's possible to retrieve the name of the players who connect to a server but I cannot find a method that can be used to know if those player are "real players" or spectators. Any ideas ?

thanks in advance,
Pietro


I started from this code:

Code: Select all

class ClassName extends Mutator config(configfile);

function preBeginPlay() {
   ...
}

function modifyLogin(out class<playerpawn> spawnClass, out string portal, out string options) {

   local string playerName;

   if (nextMutator != none) {
      nextMutator.modifyLogin(spawnClass, portal, options);
   }

   // get player name
   playerName = Level.Game.ParseOption(Options, "Name");

}

Code: Select all

ClassIsChildOf(SpawnClass, class'Spectator')

Have a look at the 'Login' event in GameInfo.

Hey Mr. P, it's gopostal. Are you going to use this on an ACE server because there is simple ways of getting everything with that.

Thanks for the infos, I'll take a look at it !

Yes, I know it's you
About ACE, I really dont' know at the moment, surely I'll do some tests on ISC server where ACE is not installed

About your original question, if you want to specifically look at spectators then you check their PRI assignments. This is a function from a HUD mutator that shows in the players screen a list of players and also spectators that Bob from dU and I wrote for monsterhunt2:

Code: Select all

simulated function DrawPlayerLists (Canvas C)
{
    local float XL, YL, YOffSetP, YOffSetS;
	 local PlayerReplicationInfo PRI;
	 local int PlayerCount, i;
    local string playerString;

    if (PlayerOwner.PlayerReplicationInfo == none || C == none) return;

	 C.Font=C.SmallFont;
	 C.DrawColor=HUDColor;

	 C.StrLen("[Player(LOCATION)] ", XL, YL);
	 C.SetPos(C.ClipX - XL, C.ClipY / 4);
	 C.DrawText("[Player(LOCATION)]",False);

	 C.StrLen("[Spectators] ",XL,YL);
	 C.SetPos(C.ClipX - XL,C.ClipY / 1.5);
	 C.DrawText("[Spectators] ",False);

	// Wipe everything.
	for ( i=0; i<ArrayCount(Ordered); i++ )
		Ordered[i] = None;
	for ( i=0; i<32; i++ )
	{
		if (PlayerPawn(Owner).GameReplicationInfo.PRIArray[i] != None)
		{
			PRI = PlayerPawn(Owner).GameReplicationInfo.PRIArray[i];
			if ( !PRI.bWaitingPlayer )
			{
				Ordered[PlayerCount] = PRI;
				PlayerCount++;
				if ( PlayerCount == ArrayCount(Ordered) )
					break;
			}
		}
	}

	SortScores(PlayerCount);

    YOffSetP = C.ClipY/4 + YL;
    YOffSetS = C.ClipY/1.5 + YL;

    for (i = 0; i < playerCount; ++i)
    {
        if (Ordered[i].PlayerName ~= "player")
        {
        }
        else
        {

            playerString = Ordered[i].PlayerName;
            if (!Ordered[i].bIsSpectator)
            {
                if (Ordered[i].PlayerLocation != none && Ordered[i].PlayerLocation.LocationName != "")
                    playerString = playerString@"("$Ordered[i].PlayerLocation.LocationName$")";
                else if (Ordered[i].PlayerZone != none && Ordered[i].PlayerZone.ZoneName != "")
                    playerString = playerString@"("$Ordered[i].PlayerZone.ZoneName$")";
            }

            if (len(playerstring) > 30)
               playerString = left(playerString, 30)$")"; // truncate if longer than 30 chars

            C.StrLen (playerString$" ", XL, YL);
            if (Ordered[i].bIsSpectator) {
                C.SetPos(C.ClipX - XL, YOffSetS);
                YOffSetS += YL;
            }
            else {
                C.SetPos(C.ClipX - XL, YOffSetP);
                YOffSetP += YL;
            }
            if (!Ordered[i].bIsSpectator && PlayerOwner.PlayerReplicationInfo.PlayerName == Ordered[i].PlayerName)
                C.DrawColor=GoldColor;
            else
                C.DrawColor=WhiteColor;

            C.DrawText (playerString, False);
        }
    }
}

You can see here that the simple switch of
if (!Ordered.bIsSpectator)
allows you to sort the players to different 'lists' easily. This is the most efficient way to do what you are wanting to do. Grab the array of players then sort them depending on the way you need them separated.

I don't think checking the PRI is possible in this case, because he wants to retrieve the information before the player actually joins the server, and therefore no player data has been replicated to the server yet / no PRI is available.

Ok, I want to be more clear about the mutator, this is the code:

Code: Select all

class ClassName extends Mutator config(configfile);

function preBeginPlay() {
   ...
}

function modifyLogin(out class<playerpawn> spawnClass, out string portal, out string options) {

   local string playerName;

   if (nextMutator != none) {
      nextMutator.modifyLogin(spawnClass, portal, options);
   }

   // get player name
   playerName = Level.Game.ParseOption(Options, "Name");

   // at this point I've to understand ONLY if the player joining the server is a spectator or not...
   
   // ...now I know it and this info is stored someway in the code

   if (...the player joining the server is a spectator...) {
		for (aPawn = level.pawnList; aPawn != none; aPawn = aPawn.nextPawn) {
			if (aPawn.isA('PlayerPawn')) {

                                                        // do something for every playerpawn in the server
                       		}
		}
   } else {
		for (aPawn = level.pawnList; aPawn != none; aPawn = aPawn.nextPawn) {
			if (aPawn.isA('PlayerPawn')) {

                                                        // do something else for every playerpawn in the server
                       		}
		}
   }
}

// other functions...

Now I have to retrieve player type data (player or spectator) by using the "Login" event in GameInfo class...

Code: Select all

class ClassName extends GameInfo

event playerpawn Login (string Portal, string Options, out string Error, class<playerpawn> SpawnClass) {

        if (ClassIsChildOf(SpawnClass, class'Spectator')) {

             // set the value of a variable so I'm able to read it ?
        }
}

How can I bind the 2 classes in order to get the infos from the second class ? thanks

There's no need to have two classes. By saying have a look at the Login event, I meant it more in the way that you can actually see how things work whenever a new player joins

The event automatically calls the mutator chain

Code: Select all

event playerpawn Login (
	string Portal,
	string Options,
	out string Error,
	class<playerpawn> SpawnClass
) {

// Other stuff

BaseMutator.ModifyLogin(SpawnClass, Portal, Options);           <-------- here

Therefore, you are able to link yourself with your mutator into this function call whenever a new player joins. Thats what you did with your modifyLogin function. Now, you can simply add this check which I posted above right into your existing function, so it looks like this:

Code: Select all

// at this point I've to understand ONLY if the player joining the server is a spectator or not...  
// ...now I know it and this info is stored someway in the code

if (ClassIsChildOf(SpawnClass, class'Spectator')) {
     // Do your stuff
}

But note that this function is called during the login process, which could still fail in (unlikely) cases and as stated in my post above doesn't give you access to the player's PRI, but if you only want to check whether the new player is a spectator or not you can ignore that

Thanks for your comments Sp0ngeb0b
I'm moving my first steps into UScript and many things are not so clear
