Time for action – tracking the flood

1. Add the following declarations to the Game1 class:

   Private Const MaxFloodCounter As Single = 100.0
   Private floodCount As Single = 0.0
   Private timeSinceLastFloodIncrease As Single = 0.0
   Private timeBetweenFloodIncreases As Single = 1.0
   Private floodIncreaseAmount As Single = 0.5

2. In the Update() method of Game1.vb, add the following code to keep track of the increasing flood waters, right after the timeSinceLastInput variable is updated in the GameState.Playing case section:

   timeSinceLastFloodIncrease +=
       CSng(gameTime.ElapsedGameTime.TotalSeconds)
   
   If timeSinceLastFloodIncrease >= timeBetweenFloodIncreases Then
       floodCount += floodIncreaseAmount
       timeSinceLastFloodIncrease = 0.0
       If (floodCount >= MaxFloodCounter) Then
           gameOverTimer = 8.0
           gameState = GameStates.GameOver
       End If
   End If
