Connect 4 C# (How to draw the grid)
- by Matt Wilde
I've worked out most of the code and have several game classes. The one bit I'm stuck on at the moment, it how to draw the actual Connect 4 grid. Can anyone tell me what's wrong with this for loop? I get no errors but the grid doesn't appear. I'm using C#.
private void Drawgrid()
{
Brush b = Brushes.Black;
Pen p = Pens.Black;
for (int xCoor = XStart, col = 0; xCoor < XStart + ColMax * DiscSpace; xCoor += DiscSpace, col++)
// x coordinate beginning; while the x coordinate is smaller than the max column size, times it by
// the space between each disc and then add the x coord to the disc space in order to create a new circle.
for (int yCoor = YStart, row = RowMax - 1; yCoor < YStart + RowMax * DiscScale; yCoor += DiscScale, row--)
{
switch (Grid.State[row, col])
{
case GameGrid.Gridvalues.Red:
b = Brushes.Red;
break;
case GameGrid.Gridvalues.Yellow:
b = Brushes.Yellow;
break;
case GameGrid.Gridvalues.None:
b = Brushes.Aqua;
break;
}
MainDisplay.DrawEllipse(p, xCoor, yCoor, 50, 50);
MainDisplay.FillEllipse(b, xCoor, yCoor, 50, 50);
}
Invalidate();
}
Thanks.
