[Extension] Player Command Control (includes CHAT-Control for Builtin-B3!)

[kung foo man]

Hey all! I'm happy to announce a new feature!

I've added a new callback into CoDScript, which is called: CodeCallback_PlayerCommand(args)

What does it do?

Lets say somebody wrote in Chat: hello
args[0] = "say"
args[1] = "hello"
(are you already dreaming about your own builtin-BigBrotherBot? )

Since its not only about chat-messages, you can catch ALL other client commands, like "mr", for menuresponses. Or even console-commands sent by client!

Type in console: /lol a command
args[0] = "lol"
args[1] = "a"
args[2] = "command"
(the command is ONLY forwarded to server, if the client couldn't execute it!)

To get a feeling of all the messages a server is arriving, just uncomment this in the callback:

		    //printf("PLAYER COMMAND! message=\"%\"\n", output);
    //self iprintlnbold("you wrote: " + output); 
	

Many new possibilities


The first functions are the normal ones, just look at the last:

		//    Callback Setup
//    This script provides the hooks from code into script for the gametype callback functions.

//=============================================================================
// Code Callback functions

/*================
Called by code after the level's main script function has run.
================*/
CodeCallback_StartGameType()
{
    // If the gametype has not beed started, run the startup
    if(!isDefined(level.gametypestarted) || !level.gametypestarted)
    {
        [[level.callbackStartGameType]]();

        level.gametypestarted = true; // so we know that the gametype has been started up
    }
}

/*================
Called when a player begins connecting to the server.
Called again for every map change or tournement restart.

Return undefined if the client should be allowed, otherwise return
a string with the reason for denial.

Otherwise, the client will be sent the current gamestate
and will eventually get to ClientBegin.

firstTime will be qtrue the very first time a client connects
to the server machine, but qfalse on map changes and tournement
restarts.
================*/
CodeCallback_PlayerConnect()
{
    self endon("disconnect");
    [[level.callbackPlayerConnect]]();
}

/*================
Called when a player drops from the server.
Will not be called between levels.
self is the player that is disconnecting.
================*/
CodeCallback_PlayerDisconnect()
{
    self notify("disconnect");
    [[level.callbackPlayerDisconnect]]();
}

/*================
Called when a player has taken damage.
self is the player that took damage.
================*/
CodeCallback_PlayerDamage(eInflictor, eAttacker, iDamage, iDFlags, sMeansOfDeath, sWeapon, vPoint, vDir, sHitLoc, timeOffset)
{
    self endon("disconnect");
    [[level.callbackPlayerDamage]](eInflictor, eAttacker, iDamage, iDFlags, sMeansOfDeath, sWeapon, vPoint, vDir, sHitLoc, timeOffset);
}

/*================
Called when a player has been killed.
self is the player that was killed.
================*/
CodeCallback_PlayerKilled(eInflictor, eAttacker, iDamage, sMeansOfDeath, sWeapon, vDir, sHitLoc, timeOffset, deathAnimDuration)
{
    self endon("disconnect");
    [[level.callbackPlayerKilled]](eInflictor, eAttacker, iDamage, sMeansOfDeath, sWeapon, vDir, sHitLoc, timeOffset, deathAnimDuration);

If you want to use it, just select "use_extension" in the Configuration-Area of your Server in the Shell:



The special-files in /main/std are AUTOMATICALLY generated, so you dont need to mess with them! So you only need to create fs_game\maps\mp\gametypes\_callbacksetup.gsc and you are ready to go.

Happy modding

[Killer.Pro]

Great work as always bro, keep it up

[Jeplaa]

No more third-party software ?
!Great job

[Jared]

Looks very nice, excited to see more features offered by your webshell

If anybody needs help to use it: just ask and I will add it to your server

[kung foo man]

The "player spawn(origin, angle)"-function is crashing the server when used in CodeCallback_PlayerCommand(args).

To prevent the Segmentation Fault, just write:

		CodeCallback_PlayerCommand(args)
{
    waittillframeend;
    // all other code...
    // all other code...
    // all other code...
} 
	

or:

		CodeCallback_PlayerCommand(args)
{
    wait 0.05;
    // all other code...
    // all other code...
    // all other code...
} 
	

Attention: Only call wait 0.05; or waittillframeend; when you really need to call the spawn-function! Because the arguments are saved in ONE global structure and when 2 players in a server write something near in the same time, the ClientCommand()-function is mixing up the data otherwise.

[IzNoGoD]

It seems to me that the spawnplayer is a special function and is the only one that requires the special attention of waittillframeend or wait 0.05. All other functions should be fine.

The extension-scripts on killtube.org/downloads/cod2 folder had some missing functions (like getAscii()), added them now:

http://killtube.org/downloads/cod2/e...rver/main/std/

(Thanks to Mitch, he told me. utils.gsc)

[kung foo man]

As IzNoGod figured out, CoD2 can handle a lot of requests, but you need:

		function disableFloodProtection(seconds)
{
    setCvar("sv_floodProtect", "0");
    wait seconds;
    setCvar("sv_floodProtect", "1");
}

thread disableFloodProtection(10); // 10 seconds of mass data incoming
