public abstract class BaseGame

extends AbstractGame

BaseGame provides the simplest possible implementation of a main game loop. Both logic and graphics are updated as quickly as possible, with no interpolation to account for shifting frame rates. It is suggested that a more complex variant of AbstractGame be used in almost all cases.

public BaseGame()

Method Detail

start

public final void start()

The simplest main game loop possible: render and update as fast as possible.

Specified by:

start in class AbstractGame

quit

protected void quit()

Quits the program abruptly using System.exit.

Specified by:

quit in class AbstractGame

See Also:

AbstractGame.quit()

update

protected abstract void update(float interpolation)

Description copied from class: AbstractGame

update updates the game state. Physics, AI, networking, score checking and like should be completed in this method. How often and when this method is called depends on the main loop implementation.

Specified by:

update in class AbstractGame

Parameters:

interpolation - unused in this implementation

See Also:

AbstractGame.update(float interpolation)

render

protected abstract void render(float interpolation)

Description copied from class: AbstractGame

render displays the game information to the OpenGL context. Nothing altering the game state should be run during a render. How often and when this method is called depends on the main loop implementation.

Specified by:

render in class AbstractGame

Parameters:

interpolation - unused in this implementation

See Also:

AbstractGame.render(float interpolation)

initSystem

protected abstract void initSystem()

Description copied from class: AbstractGame

initSystem creates all the necessary system components for the client application. It is is called once after start is called. The display must be initialized within this method.

Specified by:

initSystem in class AbstractGame

See Also:

AbstractGame.initSystem()

initGame

protected abstract void initGame()

Description copied from class: AbstractGame

initGame creates and initializes all game data required for startup. It is suggested that caching of frequently used resources is done within this method. It is called once after initSystem has completed.

Specified by:

initGame in class AbstractGame

See Also:

AbstractGame.initGame()

reinit

protected abstract void reinit()

Description copied from class: AbstractGame

reinit rebuilds the subsystems. It may be called at any time by the client application.

Specified by:

reinit in class AbstractGame

See Also:

AbstractGame.reinit()

cleanup

protected abstract void cleanup()

Description copied from class: AbstractGame

cleanup cleans up any created objects before exiting the application. It is called once after finish is called.

Specified by:

cleanup in class AbstractGame

See Also:

AbstractGame.cleanup()
