renaming

[IzNoGoD]

Hey all
Found a way to rename players without touching the "name" cvar (thus no setclientcvar needed)

Also: blocking renaming of certain players
Also: blocking renaming of certain players + renaming those players from script anyway without touching the name cvar.

Coming soon to a libcod installation near you

That's great, thanks. I wish it would be also possible to rename the server itself, i mean the "console" thing in chat.

You can already sent custom messages with sendGameServerCommand. But i think renaming "console:" to "...." is possible.

But as it is already possible with sendgameservercommand, there is no real need to find this. Just tunnel your b3 into a cvar instead of the rcon say thingy and sendgameservercommand from there.

Ok, the functions have some (initially) unintended side-effects:

The "name" cvar can be read as an input after which the script can decide to 1) rename the player to that name 2) not rename the player at all 3) rename the player to a different name.
Basically these new functions allow for a "rename" event.

Hmm it seems now on SD names are changing instantly, without having to wait till the next round, even without calling these functions, but i like it, actually.

This code will work very well with the change. It prevents duplicate names and the rename notification of players when they rename to a duplicate name and back to their old name.
Can easily be extended to prevent players from renaming on an individual basis.

Thanks for this, but there is an error in self iprintlnbold("No duplicate names allowed, also i tried this code but im getting segmentation fault on server after 30 seconds, wtf.

[Ni3ls]

Hmm it seems now on SD names are changing instantly, without having to wait till the next round, even without calling these functions, but i like it, actually.

That was already possible

setClientNameMode("auto_change");

Thanks for this, but there is an error in self iprintlnbold("No duplicate names allowed, also i tried this code but im getting segmentation fault on server after 30 seconds, wtf.

The segmentation fault is probably due to the address in gsc_player_clientuserinfochanged. (which is for 1.3 or 1.2)
I fixed the iprintlnbold error in the original code post. Now it is easier to look at the code and see what it does.

Edit: i modified the rename script to an event function like player messages. (CodeCallback_PlayerCommand)

https://github.com/M-itch/libcod/com...d949182ab52720 (+ 2 commits to fix some issues)

		CodeCallback_UserInfoChanged(clientNum)
{
    oldname = self.name;
    newname = self get_userinfo("name");
    
    if(oldname != newname)
    {
        self iprintlnbold("Your old name is " + oldname);
        self iprintlnbold("Your new name is " + newname);
    }
    
    self clientuserinfochanged();
} 
	

I updated my libcod builds for cod2 1.0 - 1.3 on http://znation.nl/libcod/ubuntu/.
