[C#] Randomly assign a unique value to 6 different variables

Unity Engine
1

Hello!

I’m creating an app in Unity that needs to have 6 different players with unique values assigned to them in a random fashion. You click a “roll” button to assign a number from 0 to 5 to each player, but two players can’t have the same number

Example:

After “rolling”; Player 1 is assigned to “4”, Player 2 is assigned to “3”, Player 3 is assigned to “0”, Player 4 is assigned to “5”, Player 5 is assigned to “1”, Player 6 is assigned to “2”.

How do I go about doing this?

Thanks in advance!

There are several ways to do this. This post has some solutions.

First add this nice little List extension snippet somewhere:

public static class EnumerableExtension
{
    public static void Shuffle<T>( this List<T> list )
    {
        int count = list.Count;
        for(int i = 0; i < count; i++)
            list.Swap( i, UnityEngine.Random.Range(i, count) );
    }
   
    public static void Swap<T>( this IList<T> list, int i, int j )
    {
        T temp = list[i];
        list[i] = list[j];
        list[j] = temp;
    }
}

Then, try something like this:

public void AssignInitiative( Player[] players )
{
   List<int> list = new List<int>();
   for (int i = 0; i < players.Length; i++)
   {
      list.Add( i );
   }

   list.Shuffle();

   for (int i = 0; i < players.Length; i++)
   {
      players.initiative = list[i];
   }
}

Hope it helps!

int[] playerValues = Enumerable.Range(0, 5).OrderBy(a => Random.value).ToArray();
