Im doing a c# maze that should fill up the screen like

x x x x x x
x x       x
x x x x x x
x x  x x x x
x  x x x x x
x x x x  x x
   x x x x x
x    
x x x x x x

The x's are places randomly and the mouse is trying to find its way out. What I am having trouble with is finding a way to fill something up with x's. I tried creating a 2D string array full of x's and fill a label, but no luck.

What is the best way of doing this? Using a panel or maybe something I don't know about? I have to do this in WFA

Answer 1

Same example as my other answer but with Windows Forms :) Its nearly the same.

  public partial class Form1 : Form
  {
    public Form1()
    {
      InitializeComponent();
    }

    private void panel1_Paint(object sender, PaintEventArgs e)
    {
      var blackPen = new Pen(Brushes.Black);
      for (int y = 0; y < 10; y++)
      {
        for (int x = 0; x < 10; x++)
        {
          e.Graphics.DrawLine(blackPen, new Point(x*20, y*20), new Point(x*20 + 10, y*20+10));
          e.Graphics.DrawLine(blackPen, new Point(x*20, y*20+10), new Point(x*20 + 10, y*20));
        }
      }
    }
  }

You have to add a Panel into your window (name it panel1 if it isn't yet) and an event handler for Paint

Nothing complicated.

Answer 2

To give you a quickstart with drawing in WPF I created a little example for you which directly draws X's into the window.

  public partial class MainWindow : Window
  {
    public MainWindow()
    {
      InitializeComponent();
      Background = Brushes.Transparent;
    }

    protected override void OnRender(DrawingContext dc)
    {
      base.OnRender(dc);
      var whitePen = new Pen();
      whitePen.Brush = Brushes.White;
      for (int y = 0; y < 10; y++)
      {
        for (int x = 0; x < 10; x++)
        {
          dc.DrawLine(whitePen, new Point(x*20, y*20), new Point(x*20 + 10, y*20+10));
          dc.DrawLine(whitePen, new Point(x*20, y*20+10), new Point(x*20 + 10, y*20));
        }
      }
    }
  }

You can add your condition like if (positions[x, y] == 1) around the DrawLine calls to prevent a specific X from being drawn.

Answer 3

After generating the random map and saving it on the 2d array, cycle trought every cell of the map (adding it to the label) and add a new line everytime it reaches the end of the row.

Also, what happened when you tried to fill the label with the 2d array map?
