Modifying the MyGLRenderer Class
The MyGLRenderer class must be modified in order to integrate the main menu, high score table,
and high score entry menu.
The GameState enumeration (see Listing 9-36) holds the general state of the game, which can be one
of the following:
MainMenu : The state where the main menu is being displayed
ActiveGamePlay : The state where the game is active
HighScoreTable : The state where the high score table is being displayed
HighScoreEntry : The state where a player is entering his or her initials after making
a high score
Listing 9-36. The Game State
enum GameState
{
MainMenu,
ActiveGamePlay,
HighScoreTable,
HighScoreEntry
}
The m_GameState variable holds the state of the game.
private GameState m_GameState = GameState.MainMenu;
The m_MainMenu variable holds a reference to the MainMenu class object that implements the
main menu.
private MainMenu m_MainMenu;
The m_HighScoreEntryMenu variable holds a reference to the HighScoreEntryMenu class object that
implements the high score entry menu system.
private HighScoreEntryMenu m_HighScoreEntryMenu;
The m_HighScoreTable variable holds a reference to the class object that implements the high
score table.
private HighScoreTable m_HighScoreTable;
The m_CanContinue variable is true if there is a previously saved game that the user can
continue from.
private boolean m_CanContinue = false;
