[RUNUO] Lady Luck - Lottery system for runuo

This is a script i butchered from DATT99's OWTLR. originally part of the token system there, i wanted a simple lottery system for my solo server. This script works with RUNUO, so some minor changes may be required for servUO.

how it works:

place lady luck somewhere
players can buy lottery tickets from the lady luck
the lottery will draw every 168 hours (7 days) as configured in the script.

Note: no winners guaranteed. The prize is set at random between 5000 and 1000000. the...

Found BUGs, the purchase of lottery tickets will not deduct the check in the bank safe.

int i_Bank;
int i_Total;
i_Bank = Banker.GetBalance( m_From );
i_Total = i_BuyTickets * i_TicketCost;

if ( i_Bank > i_Total )
{
m_From.BankBox.ConsumeTotal(typeof(Gold), i_Total);
m_From.SendLocalizedMessage( 1060398, i_Total.ToString() ); // ~1_AMOUNT~ gold has been withdrawn from your bank box.
m_From.SendLocalizedMessage( 1060022, Banker.GetBalance( m_From ).ToString() ); // You have ~1_AMOUNT~ gold in cash remaining in your bank box.

LotteryTicket lottery = new LotteryTicket();
lottery.DrawingNumber = i_Drawing;
lottery.StartTicketNumber = i_Ticket;
lottery.EndTicketNumber = (i_Ticket + i_BuyTickets - 1);
m_From.AddToBackpack( lottery );

i_Ticket = (i_Ticket + i_BuyTickets);
m_From.CloseGump( typeof( LadyLuckSellingGump ) );
m_From.SendMessage("You bought {0} lottery tickets.", i_BuyTickets);
i_Reward = ( i_Reward + ( i_BuyTickets * (i_TicketCost/2) ) );
}
else
{
m_From.PlaySound(1069); //play Hey!! sound
m_From.SendMessage("You don't have enough Money!!!!");
m_From.SendMessage("Please make sure you have enough gold in your bank.");
m_From.SendGump( new LadyLuckSellingGump( m_From ) );
}

Works for me using runuo. perhaps there's difference in how the bankbox is called if you are using servuo?

My UO station is runuo。
It is now found that there is also a problem with winning the lottery. The lottery number is 300,000 and the winning number is 500,000, which is a number that has not been purchased at all.

okay lets walk through this. the section that determines winner ticket is

C#:

                s_WinnerName = "Not claimed";
                
                // calculate odds based on amount being drawn
                
                double mixit = Utility.RandomDouble();
                if ( mixit > 0.80 ) mixit = 0.80;
                if ( mixit < 0.20 ) mixit = 0.20;
                
                double oddsdouble = ( (i_Reward / i_TicketCost) * mixit ) + i_Ticket;
                int odds = Convert.ToInt32(oddsdouble);
                
                i_Winner = Utility.RandomMinMax(1, odds);

                i_WinnerReward = i_Reward;
                dt_NextDrawing = DateTime.Now + TimeSpan.FromHours( i_DrawingDelay );
                World.Broadcast( 38, true, "And the lucky ticket that won {0} gold for drawing number {1} is {2}.", i_WinnerReward, i_Drawing, i_Winner);               
                i_Reward = Utility.RandomMinMax(5000, 1000000);
                i_Drawing++;
                i_Ticket = 1;
                World.Broadcast( 89, true, "If a player has the winning ticket, hand it in to Lady Luck!" );
                World.Broadcast( 66, true, "The next drawing will take place at {0}.", dt_NextDrawing );

so step 1: creating a mixit variable to spruce things up with a value between 0.20 and 0.80
step2: calculate the odds of winning (oddsdouble) by:
- dividing the total reward of the draw by ticket price
- multiply this value by mixit variable
- add to this value the number of tickets purchased
-convert this oddsdouble to integer to get the odds
step3: determine the winning ticket randomly between 1 and the variable odds.

in this manner, the odds of winning should always be between 20% to 80% of the winning amount divided by the ticket price (plus the number of tickets sold). for example, if the lottery is for 500,000 gold and 10 tickets were sold, for 1000 each the winning ticket will have to be between 110 and 410.

Did you change the ticket price? Did you change any other variables? As stated before, the bank instruction works on my version of runuo so it could just be a matter of a different way of calling functions in your version of runuo.

to note: the winning ticket has to be submitted before the next lottery is over.
so if you have the winning ticket for drawing #1 and the lottery is now at drawing #3 you lost your chance to win
