Time for action – displaying the flood

1. Add the following declarations to the Game1 class:

   Private Const MaxWaterHeight As Integer = 244
   Private Const WaterWidth As Integer = 297
   
   Private waterOverlayStart As Vector2 = new Vector2(85, 245)
   Private waterPosition As Vector2 = new Vector2(478, 338)

2. Modify the Draw() method of the Game1 class by adding the following, right after the SpriteBatch.DrawString() call that displays the player's score:

   Dim waterHeight As Integer 
   
   waterHeight = CInt(MaxWaterHeight * (floodCount / 100))
   
   spriteBatch.Draw(background,
       new Rectangle(
           CInt(waterPosition.X),
           CInt(waterPosition.Y + (MaxWaterHeight - waterHeight)),
           WaterWidth,
           waterHeight),
       new Rectangle(
           CInt(waterOverlayStart.X),
           CInt(waterOverlayStart.Y + (MaxWaterHeight - waterHeight)),
           WaterWidth,
           waterHeight),
       new Color(255, 255, 255, 180))

3. Try it out! You should now be able to watch the flood slowly increase in the flood tank. When...
