removing a value from a variable - SpankMe2 - 05.08.2011

Hey Guys,
So ive just came across this question i cant find a answer to.

If I create a variable called players to see how meny is online so i can divide the amount of players online by the amount of players that want HappyHour to run so like a votng system

I know how to add to variable you use this

pawn Код:

PlayerInfo[playerid][Players]++;

So how do I take away from that variable

and how can i divide that varible by 2 and get half to make the happy hour variable reach half its value before the votes for Happy Hour reach the level where it starts#

Thanks in advance.

Like this?

pawn Код:

new
    iPlayerCounts = -1
;

public OnPlayerConnect( playerid )
{
    if ( iPlayerCounts < 0 ) 
        iPlayerCounts = 0;
    else
        iPlayerCounts ++; // Increase the iPlayerCounts, you could do " iPlayerCounts += 1; "

    return 1;
}

public OnPlayerDisconnect( playerid, reason )
{
    if ( iPlayerCounts > -1 )
        iPlayerCounts --; // Take away the variable, you could use " iPlayerCounts -= 1; "

    return 1;
}

stock dividePlayersByTwo( )
    return iPlayerCounts / 2; // Divides iPlayerCounts by Two.

stock startHappyHour( )
{
    if ( ( dividePlayersByTwo( ) ) < 5 ) // if ( ( iPlayerCounts /2 ) < 5 )
        return GameTextForAll( "Not enough players", 3000, 3 );

    return 1;
}

If I understand, you are asking this.
