Alot better code, you don't need to active headshots for every playerid.
One command to enable/disable

PHP код:

new hstoggle = 1;
public OnPlayerCommandText(playerid, cmdtext[])
{
    if(!strcmp(cmdtext, "/hstoggle", true))
    {
        if(logged[playerid] == 0) return SendClientMessage(playerid, COLOR_BRIGHTRED, "You must be logged in to use that command.");
        if(PlayerInfo[playerid][pAdmin] < 2) return SendClientMessage(playerid, COLOR_BRIGHTRED, "You are not an admin!");
        switch(hstoggle)
        {
            case 0: hstoggle = 1, GameTextForAll("Headshots Enabled!", 5000, 3);
            case 1: hstoggle = 0, GameTextForAll("Headshots Disabled!", 5000, 3);
        }
        return 1;
    }
    return 0;
}
public OnPlayerGiveDamage(playerid, damagedid, Float: amount, weaponid, bodypart)
{
    if(hstoggle == 1 && damagedid != INVALID_PLAYER_ID && bodypart == 9 && (weaponid == 24 || weaponid == 33 || weaponid == 34)) SetPlayerHealth(damagedid, 0.0);
    return 1;
}
