here's the code for the problem in question

<br />
Class BlockClass<br />
{<br />
  private enum BlockColor<br />
  {<br />
    BLUE,<br />
    GREEN,<br />
    RED<br />
  }<br />
  <br />
  // some more members here<br />
<br />
  private BlockColor ItsColor;<br />
<br />
  public void AssignColor()<br />
  {<br />
    Random rnd = new Random();<br />
    switch (rnd.Next(4))<br />
    {<br />
      case 1 :<br />
        this.ItsColor = BlockColor.BLUE;<br />
        break;<br />
      case 2 :<br />
        this.ItsColor = BlockColor.GREEN;<br />
        break;<br />
      case 1 :<br />
        this.ItsColor = BlockColor.RED;<br />
        break;<br />
  }<br />
<br />
  public BlockClass(Graphics InGraphics, <br />
                         int inSpeed,<br />
                       Point inLocation,<br />
                        bool inTopRow)<br />
  {<br />
    // some other constructor code<br />
    this.AssignColor();<br />
    // some other constructor code<br />
  }<br />
}<br />


basically AssignColor() is only used as part of the object's construction it is called once per BlockClass that is created. I choose to use an enumeration so it would be easy for me to do redraw using another switch statement to either draw the block using basic graphics routines like DrawRectangle() or load a specific image from an imagelist containing the 3 color blocks plus a blank white block for redrawing purposes

to give you an idea how this class is used:

<br />
class BlocksClass<br />
{<br />
  ArrayList TheBlocks = new ArrayList(20);<br />
<br />
  public void LayoutBlocks()<br />
  {<br />
    for(int x = 0;x < 20;x++)<br />
    {<br />
      ArrayList YArray = new ArrayList(20);<br />
      for(int y = 0;y < 20;y++)<br />
      {<br />
        BlockClass Block = new BlockClass(this.Gfx,<br />
                                          this.speed,<br />
                                          new Point((x * 7) + 3,(y * 7) + 3)),<br />
                                          (y == 0))<br />
        YArray.Add(Block);<br />
      }<br />
      this.TheBlocks.Add(YArray)<br />
    }<br />
  }   <br />
}<br />


so basically the program calculates a 20x20 playing board with 7x7 pixel boxes
by filling in the Y rows of a specific X column and then moving on to the next X column and repeating (i did this cause part of the program needs to be able to delete a square and cause those above it to drop down to replace it (figured i set up the array like this it would be easier to parse for this event)

ok now i'm done typing like... working at 3am does that to me i can't shut up i mean look at me...Sleepy | :zzz:
