Need help with creating a List

Thu 10 Sep 2009, 18:56

Hello guys, this is my first post

Im using The newest LFS_External version and C#.

My problem is:

I want to create a userlist like

1. Stefan | 55Pts.
2. ABC | 25Pts.
3. TEST | 22Pts.
4....
But i dont know how.....

What ive got:

Ive got the code to find out the best LapTime from all racers on the server.
Ok, I think i can make the same with Points on Server/Database.
In this code ive got only the BestTime on the server, but how to "calculate" now the 2nd BestTime

Heres the code for BestTime in the server/ of the race.

        private void RES_RaceOrQualifyingResult(Packets.IS_RES RES)
        {
            byte UCID = Players[GetPlyIdx(RES.PLID)].UniqueID; 
                
                TimeSpan bestLap = TimeSpan.FromMilliseconds(RES.TTime);
                string bestLapStr = string.Format("{0}:{1:000}.{2:00}", bestLap.Minutes, bestLap.Seconds, bestLap.Milliseconds);
                if (RES.TTime <= BestLapTime)
                {
                BestTime = bestLapStr;//for BestTime Button
                BestLapTime = Convert.ToInt32(RES.TTime); // for checking the best time
                BestDriver = RES.UName;
                }
                
            InSim.Send_BTN_CreateButton("^0Best Lap Time:  ^2" + BestTime, Flags.ButtonStyles.ISB_LEFT | Flags.ButtonStyles.ISB_LIGHT, 7, 62, 0, 69, 1, 255, 1, false);
        }

The other stuff like the problem with points will be sloved if i know how to get 2nd BestTime 3th BestTime 4th BestTime 5....

I hope you can help me with that problem

I would add the IS_RES packets to a list and then sort them by the TTime.

private List<Packets.IS_RES> results = new List<Packets.IS_RES>();

private void RES_RaceOrQualifyingResult(Packets.IS_RES RES)
{
    // Add packet to the list.
    results.Add(RES);
}

Then to sort it you can do this.

private void SortResults()
{
    // Sort results by TTime.
    results.Sort(CompareResultsByTime);
}

private int CompareResultsByTime(Packets.IS_RES a, Packets.IS_RES b)
{
    return a.TTime.CompareTo(b.TTime);
}

Now you have a list in order of the best time than you can loop through.

foreach (Packets.IS_RES result in results)
{
    if (result.ResultNum == 0)
    {
        // Winner etc..
    }
}

Just a nitpick, you can omit the "new Comparison<Packets.IS_RES>"

private void SortResults()
{
    // Sort results by TTime.
    results.Sort(CompareResults);
}

I also like to give the comparison methods more descriptive names, like "ByTime" for example, to make the code more readable.
