Time for action – the TileMap class – part 2

1. Add methods dealing with locating map cells to the TileMap class:

   #region Information about Map Cells
   static public int GetCellByPixelX(int pixelX)
   {
       return pixelX / TileWidth;
   }
   
   static public int GetCellByPixelY(int pixelY)
   {
       return pixelY / TileHeight;
   }
   
   static public Vector2 GetCellByPixel(Vector2 pixelLocation)
   {
       return new Vector2(
           GetCellByPixelX((int)pixelLocation.X),
           GetCellByPixelY((int)pixelLocation.Y));
   }
   
   static public Vector2 GetCellCenter(int cellX, int cellY)
   {
       return new Vector2(
           (cellX * TileWidth) + (TileWidth / 2),
           (cellY * TileHeight) + (TileHeight / 2));
   }
   
   static public Vector2 GetCellCenter(Vector2 cell)
   {
       return GetCellCenter(
           (int)cell.X,
           (int)cell.Y);
   }
   
   static public Rectangle CellWorldRectangle(int cellX, int cellY)
   {
       return new Rectangle(
           cellX * TileWidth,
           cellY * TileHeight,
           TileWidth,
           TileHeight);
   }
