Step 5
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.
Step 6
You will now be in the View for the Code of Library.cs, within this type the following Code:
using Comentsys.Toolkit.WindowsAppSdk;
using Microsoft.UI;
using Microsoft.UI.Text;
using Microsoft.UI.Xaml;
using Microsoft.UI.Xaml.Controls;
using Microsoft.UI.Xaml.Media;
using Microsoft.UI.Xaml.Shapes;
using System;
using System.Collections.Generic;
using System.Globalization;
using System.Linq;
using Windows.UI;
public class Library
{
private const string title = "Deal or Not";
private const int rate = 5;
private static readonly double[] amounts =
{
0.01, 0.10, 0.50, 1, 5, 10, 50, 100, 250, 500, 750,
1000, 3000, 5000, 10000, 15000, 20000, 35000, 50000, 75000, 100000, 250000
};
private static readonly string[] colors =
{
"0026ff", "0039ff", "004dff", "0060ff", "0073ff", "0086ff",
"0099ff", "0099ff", "0099ff", "00acff", "00bfff",
"ff5900", "ff4d00", "ff4000", "ff3300", "ff2600", "ff2600",
"ff2600", "ff2600", "ff1a00", "ff1c00", "ff0d00",
};
private static readonly string[] names = {
"a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k",
"l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v"
};
private readonly Random _random = new((int)DateTime.UtcNow.Ticks);
private readonly List<double> _values = new();
private int _turn;
private bool _over;
private bool _dealt;
private double _amount;
private Dialog _dialog;
// Choose, Get Color, Get Background & Get Amount
// Get Offer & Select Box
// Add Box
// Add Row, Layout & New
}
The Class that has been defined in so far Library.cs has using for the package of Comentsys.Toolkit.WindowsAppSdk and others.
Step 7
While still in the Class for Library.cs and after the Comment of // Choose, Get Color, Get Background & Get Amount type in the following
Methods:
private List<int> Choose(int minimum, int maximum, int total) =>
Enumerable.Range(minimum, maximum)
.OrderBy(r => _random.Next(minimum, maximum))
.Take(total).ToList();
private Color GetColor(string hex)
{
byte r = byte.Parse(hex[0..^4], NumberStyles.HexNumber);
byte g = byte.Parse(hex[2..^2], NumberStyles.HexNumber);
byte b = byte.Parse(hex[4..^0], NumberStyles.HexNumber);
return Color.FromArgb(255, r, g, b);
}
private Color GetBackground(double amount)
{
var position = Array.FindIndex(amounts, a => a.Equals(amount));
return GetColor(colors[position]);
}
private Grid GetAmount(double value, Color background)
{
Grid grid = new()
{
Background = new SolidColorBrush(background)
};
TextBlock text = new()
{
Text = string.Format(new CultureInfo("en-GB"), "{0:c}", value),
HorizontalAlignment = HorizontalAlignment.Center,
VerticalAlignment = VerticalAlignment.Center,
Foreground = new SolidColorBrush(Colors.White),
Margin = new Thickness(10),
FontSize = 33
};
grid.Children.Add(text);
return grid;
}
Choose is used to select a list of randomised numbers, GetColor is used to get a Color from the hex representation of the colour and
GetBackground will use this to get the appropriate background colour based on the amount passed in. GetAmount will be used to display
an amount with an appropriate colour.
Step 8
While still in the Class for Library.cs after the Comment of // Get Offer & Select Box
type in the following Methods for GetOffer to generate an offer and SelectBox used when picking a box:
private double GetOffer()
{
int count = 0;
double total = 0.0;
foreach (double value in _values)
{
total += value;
count++;
}
double average = total / count;
double offer = average * _turn / 10;
return Math.Round(offer, 0);
}
private async void SelectBox(Button button, string name)
{
if (!_over)
{
if (_turn < names.Length)
{
button.Opacity = 0;
_amount = _values[Array.IndexOf(names, name)];
bool response = await _dialog.ConfirmAsync(
GetAmount(_amount, GetBackground(_amount)));
if (response)
{
if (!_dealt && _turn % rate == 0 && _turn > 1)
{
double offer = GetOffer();
bool accept = await _dialog.ConfirmAsync(
GetAmount(offer, Colors.Black), "Deal", "Not");
if (accept)
{
_amount = offer;
_dealt = true;
}
}
_turn++;
}
}
if (_turn == names.Length || _dealt)
_over = true;
}
if (_over)
{
object content = _dealt ?
GetAmount(_amount, Colors.Black) :
GetAmount(_amount, GetBackground(_amount));
await _dialog.ConfirmAsync(content, "Game Over", null);
}
}
Step 9
While still in the Class for Library.cs after the Comment of // Add Box type the following Method:
private void AddBox(StackPanel panel, string name, int value)
{
Button button = new()
{
Name = $"box.{name}",
Margin = new Thickness(5)
};
button.Click += (object sender, RoutedEventArgs e) =>
SelectBox((Button)sender, name);
StackPanel box = new()
{
Width = 100
};
Rectangle lid = new()
{
Height = 10,
Fill = new SolidColorBrush(Colors.DarkRed)
};
Grid front = new()
{
Height = 75,
Background = new SolidColorBrush(Colors.Red)
};
Grid label = new()
{
Width = 50,
Background = new SolidColorBrush(Colors.White),
HorizontalAlignment = HorizontalAlignment.Center,
VerticalAlignment = VerticalAlignment.Center
};
TextBlock text = new()
{
TextAlignment = TextAlignment.Center,
FontWeight = FontWeights.Bold,
Foreground = new SolidColorBrush(Colors.Black),
FontSize = 32,
Text = value.ToString()
};
label.Children.Add(text);
front.Children.Add(label);
box.Children.Add(lid);
box.Children.Add(front);
button.Content = box;
panel.Children.Add(button);
}
AddBox is used to add a box that can be selected when Clicked to the game and give it a game-specific appearance using various elements to
create the look-and-feel of the box that can be selected.
Step 10
While still in the Class for Library.cs after the Comment of // Add Row, Layout & New type the following Methods
of AddRow which will add a row of boxes for the game, Layout which will create the look-and-feel for the game and New which will start a game.
private StackPanel AddRow()
{
int count = 0;
StackPanel panel = new();
int[] rows = { 5, 6, 6, 5 };
for (int r = 0; r < 4; r++)
{
StackPanel places = new()
{
Orientation = Orientation.Horizontal,
HorizontalAlignment = HorizontalAlignment.Center
};
for (int column = 0; column < rows[r]; column++)
{
AddBox(places, names[count], count + 1);
count++;
}
panel.Children.Add(places);
}
return panel;
}
private void Layout(Grid grid)
{
grid.Children.Clear();
Viewbox view = new()
{
Child = AddRow()
};
grid.Children.Add(view);
}
public void New(Grid grid)
{
_turn = 0;
_amount = 0;
_over = false;
_dealt = false;
_dialog = new Dialog(grid.XamlRoot, title);
var positions = Choose(0, names.Length, names.Length);
foreach (var position in positions)
{
_values.Add(amounts[position]);
}
Layout(grid);
}
Step 11
Step 12
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 13
While still in the XAML for MainWindow.xaml above </Window>, type in the following XAML:
<Grid>
<Viewbox>
<Grid Margin="50" Name="Display"
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 Grid.
It has a Loaded event handler for New which is also shared by theAppBarButton.
Step 14
Step 15
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 16
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 the Class 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 17
Step 18
Once running you can then select one of the boxes and an amount will be displayed but each five turns, then you'll have the chance to take a Deal or Not and can continue until there is just one box left, which you'll win the amount, but if you took the Deal then you win that amount instead, or you can select New to start a new game.
Step 19
