Gets max value - Nin9r - 21.06.2016

Hi !

I want to make a bid system for houses.

So, when i start the bid, players will type /bid amount to bid for it.


I don't know how can I detect after 2 minutes which offered the highest amount for the bid.

I use
/bid amount, and variable:

PlayerInfo[playerid][pBidAmount] = amount;

If you're only going to have 1 bid at any one time, you can create another player related variable that will determine which house is involved in the bidding. Then run a comparison with a for loop.

Код:
new miscarray[155], highest = 0, string[42];
for(new i; i < MAX_PLAYERS; i++
{
if(PlayerInfo[playerid][pBidAmount] > highest)
{
highest = PlayerInfo[playerid][pBidAmount];
GetPlayerName(i, string, sizeof(string));
}
}
format(miscarray, sizeof(miscarray), "%s has won the bid with %d", string, highest);
SendClientMessage(playerid, -1, miscarray);
That's the rough idea as to how you could approach that.

Here:
PHP код:
new HighestBid,
      BidLeader,
      AuctionStarted;

forward BidTimer();

CMD:startauction(playerid)
{
     AuctionStarted = 1;
     BidLeader = -1;
     HighestBid= -1;
     SetTimer("BidTimer", 120000, false); //Two minutes
     SendClientMessage(playerid, -1, "Auction has started! Use (/bid)");
     return 1;
}

public BidTimer()
{
     AuctionStarted = 0;
     new string[128];
     format(string, 128, "The winner was ID %i with their bet of $%i", BidLeader, HighestBid);
     SendClientMessageToAll(-1, string);
     //Do whatever you want with BidLeader as playerid.
}

CMD:bid(playerid, params[])
{
     if(AuctionStarted != 1) return SendClientMessage(playerid, -1, "There's not auction.");
     new bid;
     if(!sscanf(params, "i", bid))
     {
           if(bid > HighestBid)
           {
                BidLeader = playerid;
                HighestBid = bid;
           }
           else
           {
                new string[128];
                format(string, 128, "Sorry, you made a too low bid, current bid is: $%i by ID %i", HighestBid, BidLeader);
                SendClientMessage(playerid, -1, string);
           }
     }
     else
          SendClientMessage(playerid, -1, "USAGE: /bid [value]");
     return 1;
}

hello , the variable must not create the enum of the player but the enum of the house :
Quote:

HouseInfo [ HouseID ] [ BidAmount ]
HouseInfo [ HouseID [ BidPlayer ]
then,

in function or cmd of the offer :
Quote:

if ( offer > HouseInfo [ HouseID ] [ BidAmount ] )
{
HouseInfo [ HouseID ] [ BidAmount ] = offer ;
HouseInfo [ HouseID ] [ BidPlayer ] = playerid ;
}
Timer :
Quote:

SetTimerEx ( " UpdateBidAmount " , 120000 , false , " d " , HouseID ) ;
I hope I was clear.

Yes i know , but if a player bid and after he will be disconnected the auction will be failed.

I want to check somehow at final which is the winner.
