Recently, due to the need of work, do a simple program of C #. After learning some basic things, write them down first.
There are mainly:
1. Generate the initial framework
STEP 2 Disturb the order
3. In the game part, only Text and Visible parts are exchanged with the blank part after clicking the button
const int N = 4; // Number of rows and columns
Button[,] buttons = new Button[N, N];
private void Form1_Load(object sender, EventArgs e)
{
// Generate all buttons
GenerateAllButtons();
}
private void button1_Click(object sender, EventArgs e)
{
// Disturb the order
Shuffle();
}
// Generate button
void GenerateAllButtons()
{
int x0 = 100, y0 = 10, w = 45, d = 50;
for( int row = 0; row < N; row++ )
for ( int col = 0; col < N; col++ )
{
int num = row * N + col; // Digital number
Button btn = new Button();
btn.Text = (num + 1).ToString();
btn.Top = y0 + row * d;
btn.Left = x0 + col * d;
btn.Width = w;
btn.Height = w;
btn.Visible = true;
btn.Tag = row * N + col; //button Position
// Registration button Click event
btn.Click += new EventHandler(btn_Click);
buttons[row, col] = btn;
this.Controls.Add(btn);
}
buttons[N - 1, N - 1].Visible = false;
}
void Shuffle()
{
Random rnd = new Random();
for (int i = 0; i < 100; i++ )
{
int a = rnd.Next(N);
int b = rnd.Next(N);
int c = rnd.Next(N);
int d = rnd.Next(N);
Swap(buttons[a, b], buttons[c, d]);
}
}
// Play a game
private void btn_Click(object sender, EventArgs e)
{
Button btn = sender as Button;
Button blank = FindHiddenButton();
// Judge whether it is adjacent or not
if ( IsNeighbor(btn, blank) )
{
Swap(btn, blank);
blank.Focus();
}
// Judge whether it is completed
if ( ResultIsOk() )
{
MessageBox.Show("OK!");
}
}
// Find Blank Button
Button FindHiddenButton()
{
for (int row = 0; row < N; row++)
for (int col = 0; col < N; col++)
{
if (!buttons[row,col].Visible)
{
return buttons[row, col];
}
}
return null;
}
// Judge whether it is adjacent or not
bool IsNeighbor(Button btnA, Button btnB)
{
int a = (int)btnA.Tag;
int b = (int)btnB.Tag;
int r1 = a / N, c1 = a % N;
int r2 = b / N, c2 = b % N;
if ( (r1 == r2 && (c1 == c2 + 1 || c1 == c2 - 1))
|| (c1 == c2 && (r1 == r2 + 1 || r1 == r2 - 1)) )
return true;
return false;
}
// Check whether it is complete
bool ResultIsOk()
{
for (int r = 0; r < N; r++)
for (int c = 0; c < N; c++)
{
if (buttons[r, c].Text != (r * N + c + 1).ToString())
{
return false;
}
}
return true;
}
// Swap two buttons
void Swap(Button btna, Button btnb)
{
string t = btna.Text;
btna.Text = btnb.Text;
btnb.Text = t;
bool v = btna.Visible;
btna.Visible = btnb.Visible;
btnb.Visible = v;
}
