All those variables you create yourself. For example, minutes on, hours on, kills, deaths, etc etc. You can basically use everything in variables. The thing is, you need to set the variables first. Let me give you an example:

pawn Code:

public OnPlayerDeath(playerid, killerid, reason)
{
// We check if killerid is a valid player id and give him one kill
    if(killerid != INVALID_PLAYER_ID)
        SetPVarInt(playerid, "Kills", GetPVarInt(playerid, "Kills") + 1);
    SetPVarInt(playerid, "Deaths", GetPVarInt(playerid, "Deaths") + 1); // Here we set a variable called "Deaths" to the player who died
    return 1;
}
// We create a command that resets a player kills
YCMD:resetkills(playerid, params[], help)
{
        #pragma unused help, params
        DeletePVar(playerid, "Kills");
        return 1;
}
// A command that resets deaths
YCMD:resetdeaths(playerid, params[], help)
{
        #pragma unused help, params
        DeletePVar(playerid, "Deaths");
        return 1;
}
// A command to check kills and deaths:
YCMD:checkstats(playerid, params[], help)
{
        #pragma unused help, params
        new str[128];
        format(str, sizeof str, "You have %i kills and %i deaths.", GetPVarInt(playerid, "Kills"), GetPVarInt(playerid, "Deaths"))
        SendClientMessage(playerid, -1, str);
        return 1;
}

Now, you might wonder, why do I delete those variables. Well, instead of setting a player variable to 0, it's better to delete it. You can of course, set it to 0 using "SetPVarInt(playerid, "Deaths", 0);

Now, the "Kills" and "Deaths" variables, you can name it whatever you want. It doesn't matter.
