Lucky Roshambo

Learn creating a Lucky Roshambo game using Windows App SDK with this Tutorial

Lucky Roshambo shows how you can create simple Rock-Paper-Scissors game or Roshambo as it is known in parts of North America, using emoji and with a toolkit from NuGet using the Windows App SDK.

Step 1

Follow Setup and Start on how to get Setup and Install what you need for Visual Studio 2022 and Windows App SDK.

In Windows 11 choose Start and then find or search for Visual Studio 2022 and then select it.

Once Visual Studio 2022 has started select Create a new project.

Then choose the Blank App, Packages (WinUI in Desktop) and then select Next.

After that in Configure your new project type in the Project name as LuckyRoshambo, then select a Location and then select Create to start a new Solution.

Step 2

Then in Visual Studio within Solution Explorer for the Solution, right click on the Project shown below the Solution and then select Manage NuGet Packages...

Manage NuGet Packages

Step 3

Then in the NuGet Package Manager from the Browse tab search for Comentsys.Toolkit.WindowsAppSdk and then select Comentsys.Toolkit.WindowsAppSdk by Comentsys as indicated and select Install

NuGet Package Manager Comentsys.Toolkit.WindowsAppSdk

This will add the package for Comentsys.Toolkit.WindowsAppSdk to your Project. If you get the Preview Changes screen saying Visual Studio is about to make changes to this solution. Click OK to proceed with the changes listed below. You can read the message and then select OK to Install the package.

Step 4

Then while still in the NuGet Package Manager from the Browse tab search for Comentsys.Assets.FluentEmoji and then select Comentsys.Assets.FluentEmoji by Comentsys as indicated and select Install

This will add the package for Comentsys.Assets.FluentEmoji to your Project. If you get the Preview Changes screen saying Visual Studio is about to make changes to this solution. Click OK to proceed with the changes listed below. You can read the message and then select OK to Install the package, then you can close the tab for Nuget: LuckyRoshambo by selecting the x next to it.

Step 5

Then in Visual Studio within Solution Explorer for the Solution, right click on the Project shown below the Solution and then select Add then New Item…

Add New Item

Step 6

Then in Add New Item from the C# Items list, select Code and then select Code File from the list next to this, then type in the name of Library.cs and then Click on Add.

Add New Code File

Step 7

You will now be in the View for the Code of Library.cs, within this type the following Code:


using Comentsys.Assets.FluentEmoji;
using Comentsys.Toolkit.WindowsAppSdk;
using Microsoft.UI.Xaml;
using Microsoft.UI.Xaml.Controls;
using System;

public class Library
{
    private const string title = "Lucky Roshambo";
    private const int size = 3;
    private const int lost = 0;
    private const int win = 1;
    private const int draw = 2;

    private static readonly int[,] _match = new int[size, size]
    {
            { draw, lost, win },
            { win, draw, lost },
            { lost, win, draw }
    };
    private static readonly FluentEmojiType[] _assets = new FluentEmojiType[]
    {
        FluentEmojiType.Rock,
        FluentEmojiType.PageWithCurl,
        FluentEmojiType.Scissors
    };
    private static readonly string[] _values = new string[]
    {
        "You Lost!",
        "You Win!",
        "You Draw!"
    };
    private readonly Random _random = new((int)DateTime.UtcNow.Ticks);
    private Dialog _dialog;

    // Asset & Play

    // Get & New

}

The Class that has been defined in so far Library.cs has using for the packages that were added of Comentsys.Assets.FluentEmoji and Comentsys.Toolkit.WindowsAppSdk amongst others needed. There are also some const and readonly values for parts of the game such as the FluentEmojiType for Rock, Page with Curl for Paper and Scissors and to represent the board along with a Dialog that will be used to display messages in the game.

Step 8

Still in the Class for Library.cs after the Comment of // Asset & Play type the following Methods:


private Viewbox Asset(int asset) => new()
{
    Width = 100,
    Height = 100,
    Child = new Asset
    {
        AssetResource = FlatFluentEmoji.Get(_assets[asset])
    }
};

private void Play(int option)
{
    int computer = _random.Next(0, size - 1);
    var result = _match[option, computer];
    var content = new StackPanel()
    {
        Orientation = Orientation.Vertical
    };
    content.Children.Add(new TextBlock()
    {
        HorizontalTextAlignment = TextAlignment.Center,
        Text = "Computer Picked"
    });
    content.Children.Add(Asset(computer));
    content.Children.Add(new TextBlock()
    {
        HorizontalTextAlignment = TextAlignment.Center,
        Text = _values[result]
    });
    _dialog.Show(content);
}

Asset will be used to get the relevant asset to display the Rock, Paper or Scissors and Play will be used when it is time to see if can beat the selection of Rock, Paper or Scissors with your own selection and will display a message showing what the result is.

Step 9

While still in the Class for Library.cs after the Comment of // Get & New type in the following Methods:


private Button Get(int option)
{
    Button button = new()
    {
        Width = 150,
        Height = 150,
        Tag = option,
        Content = Asset(option),
        Margin = new Thickness(5)
    };
    button.Click += (object sender, RoutedEventArgs e) =>
        Play((int)((Button)sender).Tag);
    return button;
}

public void New(StackPanel panel)
{
    _dialog = new Dialog(panel.XamlRoot, title);
    panel.Children.Clear();
    for (int index = 0; index < size; index++)
    {
        panel.Children.Add(Get(index));
    }
}

Get is used to obtain a Button and set the Event for Click to use the Method for Play and New is used to create the look-and-feel for the game and to start the game.

Step 10

Within Solution Explorer for the Solution double-click on MainWindow.xaml to see the XAML for the Main Window.

Step 11

In the XAML for MainWindow.xaml there will be some XAML for a StackPanel, this should be Removed:


<StackPanel Orientation="Horizontal" 
HorizontalAlignment="Center" VerticalAlignment="Center">
    <Button x:Name="myButton" Click="myButton_Click">Click Me</Button>
</StackPanel>

Step 12

While still in the XAML for MainWindow.xaml above </Window>, type in the following XAML:


<Grid>
    <Viewbox>
        <StackPanel Margin="50" Name="Display" Orientation="Horizontal" 
        HorizontalAlignment="Center" VerticalAlignment="Center" Loaded="New"/>
    </Viewbox>
    <CommandBar VerticalAlignment="Bottom">
        <AppBarButton Icon="Page2" Label="New" Click="New"/>
    </CommandBar>
</Grid>

This XAML contains a Grid with a Viewbox which will Scale a StackPanel. It has a Loaded event handler for New which is also shared by the AppBarButton.

Step 13

Within Solution Explorer for the Solution select the arrow next to MainWindow.xaml then double-click on MainWindow.xaml.cs to see the Code for the Main Window.

Step 14

In the Code for MainWindow.xaml.cs there be a Method of myButton_Click(...) this should be Removed by removing the following:


private void myButton_Click(object sender, RoutedEventArgs e)
{
    myButton.Content = "Clicked";
}

Step 15

Once myButton_Click(...) has been removed, within the Constructor of public MainWindow() { ... } and below the line of this.InitializeComponent(); type in the following Code:


private readonly Library _library = new();

private void New(object sender, RoutedEventArgs e) =>
    _library.New(Display);

Here an Instance of Library is created then below this is the Method of New that will be used with Event Handler from the XAML, this Method uses Arrow Syntax with the => for an expression body which is useful when a Method only has one line.

Step 16

That completes the Windows App SDK application. In Visual Studio 2022 from the Toolbar select LuckyRoshambo (Package) to Start the application.

Step 17

Once running you can then press on the first button - Rock, the second button for Paper or the third button for Scissors then you can see what the Computer selects to see if you Win, Lose or Draw or you can restart the game by selecting New.

Step 18

To Exit the Windows App SDK application, select the Close button from the top right of the application as that concludes this Tutorial for Windows App SDK from tutorialr.com!
