Time for action – structuring the game

1. In the EnemyManager class, change the default value of the Active member from True to False:

   Public Active As Boolean = False

2. In the Game1.vb file, modify the declaration for the gameState variable to set the default to GameStates.TitleScreen:

   Private gameState As GameStates = GameStates.TitleScreen

3. Right-click on the Fonts folder in the content project, and select Add | New Item... Create a new SpriteFont object named Pericles14.spritefont.

4. The XML file for the SpriteFont will open automatically. Change the <FontName> tag from Segoe UI Mono to Pericles.

5. Add the following declarations to the Game1 class:

   Public pericles14 As SpriteFont
   
   Private playerDeathDelayTime As Single = 10
   Private playerDeathTimer As Single = 0
   Private titleScreenTimer As Single = 0
   Private titleScreenDelayTime As Single = 1
   
   Private playerStartingLives As Integer = 3
   Private playerStartLocation As Vector2 = New Vector2(390, 550)
   Private scoreLocation As Vector2 = New Vector2...
