Do something after player enter/leave the server

[iloveut99]

class code extends LastManStanding;

event PostLogin( playerpawn NewPlayer ){
super.PostLogin(NewPlayer);
log("Player Enterered");
}

function Logout( pawn Exiting ){
super.Logout(Exiting);
log("Player Left");
}

I'm using this code in a lms game but it doesn't logs what I write, seems the event/function don't get called. I'm spawning this class from a mutator.

Anyone got an idea why it isn't working?

Afaik the LastManStanding is a gameype, only works if it's the current gametype running, and the same applies to its subclasses.
Therefore you can't just spawn it to use it's events.

In the context of a mutator you have this:

Code: Select all

function ModifyLogin(out class<playerpawn> SpawnClass, out string Portal, out string Options)
{
    if ( NextMutator != None )
        NextMutator.ModifyLogin(SpawnClass, Portal, Options);
}

This is called from every gametype's "Login(...)" function, so you can use that instead of PostLogin I think.

Regarding the logout, well, I am not sure what you can do about this one, there are some ideas I have in mind, but only someone who already had to use such events should enlighten you better and lead you the proper way.

But basically, on logout, the player ceases to exist, perhaps you should go from there, idk.

is there a way to access the playerpawn with the ModifyLogin function?

The mutator is just for use in LMS gametype. But even so it will not work if overwrite the gametype functions?

function ModifyLogin(out class<playerpawn> SpawnClass, out string Portal, out string Options)
{
    if ( NextMutator != None )
        NextMutator.ModifyLogin(SpawnClass, Portal, Options);
}

I read about this function but seems it also is called after a player respawn. Is this correct?

Thanks for all the help.

Yes, ModifyPlayer is called everytime on a mutator when a player respawn. If you only want to call it when the player enters the game, make sure that the players hasn't died yet.

Should look like this:

Code: Select all

function ModifyPlayer(Pawn Other) {
  if(Other.IsA('TournamentPlayer') && Other.PlayerReplicationInfo.Deaths < 1) {
    
     // Do something here
   }
   if (NextMutator != None) NextMutator.ModifyPlayer(Other);
}

Taking tracks of player leaving is a bit tricky though, I recommend creating a player-structure and then check each tick whether a player joined/left.

EDIT: Here's a good tutorial on how to maintain the player structure. Link

My idea was to optimizes the code at max. But if I need to use timers/ticks functions I will just forget it, and do a timer that do some checks every 5 seconds for example. It would be enough.

I though it could be simpler to check if a player left, with overriding functions. (probably I could do that if I create a new gametype extending to lms)

Thanks to all. I should release the mutator soon, and I can say now too that it will try optimize the bots in lms. (which now tend to block the server without letting players enter)

Hi again,

What's it's the easier way to addbots to the game via uscript? Tried Engine.GameInfo.AddBot() but seems isn't recognized.

Well, if you're basing yourself in the console commands, let me say that none of them run from GameInfo. They are all (or at least most of them) within the PlayerPawn class: all the functions started with the "exec" modfier.

If the case of PlayerPawn class, that function is this one:

Code: Select all

exec function AddBots(int N)
{
    ServerAddBots(N);
}

function ServerAddBots(int N)
{
    local int i;

    if ( !bAdmin && (Level.Netmode != NM_Standalone) )
        return;

    if ( !Level.Game.bDeathMatch )
        return;

    for ( i=0; i<N; i++ )
        Level.Game.ForceAddBot();
}

Basically, you can implement the code directly as a function in your own class like this:

Code: Select all

function AddBots(int N)
{
    local int i;

    if ( !Level.Game.bDeathMatch )
        return;

    for ( i=0; i<N; i++ )
        Level.Game.ForceAddBot();
}

It's basically the same as ServerAddBots, but without the admin checks.

Ha awesome, thanks!

Abraço.
