        static void Main(string[] args)
        {
            string komputer = " ", user;
            int win = 0, loss = 0, draw = 0;
            var rand = new Random();
            switch (rand.Next(2))
            {
                case 0:
                    komputer = "N"; break;
                case 1:
                    komputer = "K"; break;
                case 2:
                    komputer = "P"; break;
            }
            Console.WriteLine("P - papier, N - nożyce, K - Kamień");
            user = Console.ReadLine();
            if (user == "p")
            {
                Papier(user, komputer, win, loss, draw);
            }

        }

        static int Papier(string user, string komputer, int win, int loss, int draw)
        {

        }

        static int Papier(string user, string komputer, int win, int loss, int draw)

            return win;
            return loss;
            return draw;
        }
    }
}

You can return a tuple if you don't want to create a new class

static (int, int, int) Foo()
{
   return (1, 2, 3);
}

static (int, int, int) Foo()
{
   return (1, 2, 3);
}

But not sure why you'd like to return the same value as the parameters

CzkafekOP•2y ago

How can I use tuples? em

Thinker•2y ago

static (int, int, int) Foo()
{
    return (1, 2, 3);
}

static (int, int, int) Foo()
{
    return (1, 2, 3);
}

var (a, b, c) = Foo();

var (a, b, c) = Foo();

So in your case,

static (int, int, int) Papier(string user, string komputer, int win, int loss, int draw)
{
    if (komputer == "N")
    {
        Console.WriteLine("Przegrałeś! Wyniki:");
        Console.WriteLine();
    }
    return (win, loss, draw);
}

static (int, int, int) Papier(string user, string komputer, int win, int loss, int draw)
{
    if (komputer == "N")
    {
        Console.WriteLine("Przegrałeś! Wyniki:");
        Console.WriteLine();
    }
    return (win, loss, draw);
}

I see thanks

You could also use a class or a record, but a tuple is probably the easiest here.

CzkafekOP•2y ago

thats record?

Thinker•2y ago

A tuple is not a record

CzkafekOP•2y ago

whats*

Thinker•2y ago

A record would look like this

record PapierResult(int Win, int Loss, int Draw);

static PapierResult(/* ... */)
{
    // ...
    return new PapierResult(win, loss, draw);
}

record PapierResult(int Win, int Loss, int Draw);

static PapierResult(/* ... */)
{
    // ...
    return new PapierResult(win, loss, draw);
}

Translate error?

CzkafekOP•2y ago

for a non-satic field, method, or propert ... an object reference is required

TheRanger•2y ago

well like it says, an object reference is required to access this method it was static in ur code, did u remove that word?

CzkafekOP•2y ago

nope

CzkafekOP•2y ago

Angius•2y ago

You gave it two return types int (int, int, int) Does it return an int? Or an (int, int, int)?

CzkafekOP•2y ago
