Hangman game in Silverlight

All work and no play makes Jack a dull boy. It means that without time off from work, a person becomes both bored and boring. So come and play the hangman game.

What is this game?

Hangman is a word guessing game. The player tries to guess it by suggesting letters.

The word to guess is represented by a row of dashes, giving the number of letters. If the guessing player suggests a letter which occurs in the word, the other player writes it in all its correct positions. If the suggested letter does not occur in the word, the other player draws one element of the hangman diagram as a tally mark.

Let's see how to implement this in our program.

First thing we need is to design the page.

Below is the XAML for our page.

Rest of the controls you see on page load is done dynamically in code behind. Let's see each one of this separately.

For showing 26 alphabets I have created buttons for each on them as shown below:

for (int i = 0; i < 26; i++)
{
    Button b = new Button();
    b.Name = "b" + i;
    b.Content = alph[i];
    b.Width = 25;
    b.Height = 25;
    b.FontWeight = FontWeights.Bold;
    sp.Children.Add(b);
}

Where "alph" is an array of alphabets. This buttons are placed in a stackpanel named "sp".

Now, on every page load we select random words and accordingly we show separate dashes for the number of characters in the word. The code is as follows:

Random r = new Random();
s = words[r.Next(0, words.Length)];
for (int j = 0; j < s.Length; j++)
{
    r1 = new Rectangle();
    r1.Width = 25;
    r1.Height = 5;
    SolidColorBrush sb1 = new SolidColorBrush();
    sb1.Color = Colors.Black;
    r1.Fill = sb1;
    TextBox t = new TextBox();
    t.Name = "t" + j;
    t.Text = s[j].ToString().ToUpper();
    t.Visibility = Visibility.Collapsed;
    t.Width = 25;
    t.Height = 25;
    t.IsEnabled = false;
    g.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength((double)40) });
    g1.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength((double)40) });
    g1.ShowGridLines = true;
    Grid.SetColumn(t, j);
    Grid.SetColumn(r1, j);
    if (t.Text != " ")
    {
        g.Children.Add(r1);
        g1.Children.Add(t);
    }
    nooftxtbox++;
}

Now we will see the actual functioning of the program. On every button click I am matching the character from button and the characters in the word. When we have matching character display it in its position. Else we draw one part of the body of the man to indicate that the guess is wrong. For every wrong guess we draw one part of the body.

After six wrong attempts the game finishes.

Here is the code:

bstr = ((Button)sender).Content.ToString();
for (int j = 0; j <= nooftxtbox; j++)
{
    txtName = g1.Children[j] as TextBox;
    if (txtName.Text == bstr)
    {
        txtName.SetValue(Grid.ColumnProperty, j);
        txtName.Visibility = Visibility.Visible;
        txtName.IsEnabled = false;
        ((Button)sender).Visibility = Visibility.Collapsed;
        flag = true;
    }
    else
    {
        ((Button)sender).Visibility = Visibility.Collapsed;
    }
}

Code for restarting the application(Try again button code):

private void trybutton_Click(object sender, RoutedEventArgs e)
{
    this.LayoutRoot.Children.Add(new MainPage());
}
