[SD] Enable multikill

[IzNoGoD]

Heres the result: http://social.xfire.com/video/62f82e

Changes to make to your sd file:
in callback_startgametype:

		    thread limitmultikill(); 
	

This will fix an infinite issue which crashes the server in the vid

In callback_playerdamage, in the else of if(isPlayer(eAttacker) && (self != eAttacker) && (self.pers["team"] == eAttacker.pers["team"])):

		        else
        {
            // Make sure at least one point of damage is done
            if(iDamage < 1)
                iDamage = 1;
            self makepassthroughbullet(eInflictor, eAttacker, iDamage, iDFlags, sMeansOfDeath, sWeapon, vPoint, vDir, sHitLoc, psOffsetTime);
            self finishPlayerDamage(eInflictor, eAttacker, iDamage, iDFlags, sMeansOfDeath, sWeapon, vPoint, vDir, sHitLoc, psOffsetTime);

            // Shellshock/Rumble
            self thread maps\mp\gametypes\_shellshock::shellshockOnDamage(sMeansOfDeath, iDamage);
            self playrumble("damage_heavy");
        } 
	

spawnplayer:

		    waittillframeend;
    self notify("spawned_player");
    if(isdefined(self.eyemarker))
        self.eyemarker delete();
    self.eyemarker = spawn("script_origin", self geteye());
    self.eyemarker thread deleteonevent("disconect", self);
    self.eyemarker thread deleteonevent("spawned_player", self);
    self thread linkeyemarker(self.eyemarker);
} 
	

and finally, the additional functions:

		deleteonevent(ev, us)
{
    us waittill(ev);
    if(isdefined(self))
        self delete();
}

linkeyemarker(marker)
{
    wait 0.05;
    if(!isdefined(self) || !isdefined(self.sessionstate) || self.sessionstate != "playing")
    {
        if(isdefined(marker))
            marker delete();
        return;
    }
    if(isdefined(marker))
    {
        marker.linked = true;
        marker linkto(self, "tag_eye", (0,0,0), (0,0,0));
    }
}

makepassthroughbullet(eInflictor, eAttacker, iDamage, iDFlags, sMeansOfDeath, sWeapon, vPoint, vDir, sHitLoc, psOffsetTime)
{
    if(!isdefined(vDir) || !isdefined(vPoint) || !isdefined(eAttacker) || !isplayer(eAttacker))
        return;

    if(!isdefined(sMeansOfDeath) || sMeansOfDeath != "MOD_RIFLE_BULLET")
        return;
    trace = bullettrace(vPoint, maps\mp\_utility::vectorscale(vDir, 1000) + vPoint, true, self);
    sHitLoc = "none";
    if(isdefined(trace["entity"]) && isplayer(trace["entity"]))
    {
        if(isdefined(trace["entity"].eyemarker) && isdefined(trace["entity"].eyemarker.linked))
        {
            vec = trace["entity"].eyemarker.origin - trace["position"];
            amount = vectordot(vec, vDir);
            new = trace["position"] + maps\mp\_utility::vectorscale(vDir, amount);
            if(distancesquared(new, trace["entity"].eyemarker.origin) < 10 * 10)
            {
                sHitLoc = "head";
                iDamage *= 2;
            }
        }
        level.multikill++;
        if(level.multikill > 3)
            return;
        trace["entity"] thread [[level.callbackPlayerDamage]](eInflictor, eAttacker, int(iDamage * 0.5), iDFlags, sMeansOfDeath, sWeapon, trace["position"], vDir, sHitLoc, psOffsetTime);
    }
}

limitmultikill()
{
    while(true)
    {
        level.multikill = 0;
        wait 0.05;
    }
}
