Field Detail

cam

protected Camera cam

The camera that we see through.

rootNode

protected Node rootNode

The root of our normal scene graph.

input

protected InputHandler input

Handles our mouse/keyboard input.

timer

protected Timer timer

High resolution timer for jME.

tpf

protected float tpf

Simply an easy way to get at timer.getTimePerFrame(). Also saves time so you don't call it more than once per frame.

lightState

protected LightState lightState

A lightstate to turn on and off for the rootNode

Constructor Detail

SimpleHeadlessApp

public SimpleHeadlessApp()

Method Detail

update

protected final void update(float interpolation)

This is called every frame in BaseGame.start()

Specified by:

update in class BaseHeadlessApp

Parameters:

interpolation - unused in this implementation

See Also:

AbstractGame.update(float interpolation)

render

protected final void render(float interpolation)

This is called every frame in BaseGame.start(), after update()

Specified by:

render in class BaseHeadlessApp

Parameters:

interpolation - unused in this implementation

See Also:

AbstractGame.render(float interpolation)

initSystem

protected final void initSystem()

Creates display, sets up camera, and binds keys. Called in BaseGame.start() directly after the dialog box.

Specified by:

initSystem in class BaseHeadlessApp

See Also:

AbstractGame.initSystem()

initGame

protected final void initGame()

Creates rootNode, lighting, statistic text, and other basic render states. Called in BaseGame.start() after initSystem().

Specified by:

initGame in class BaseHeadlessApp

See Also:

AbstractGame.initGame()

simpleInitGame

protected abstract void simpleInitGame()

Called near end of initGame(). Must be defined by derived classes.

simpleUpdate

protected void simpleUpdate()

Can be defined in derived classes for custom updating. Called every frame in update.

simpleRender

protected void simpleRender()

Can be defined in derived classes for custom rendering. Called every frame in render.

reinit

unused

Specified by:

reinit in class BaseHeadlessApp

See Also:

AbstractGame.reinit()

cleanup

protected void cleanup()

Cleans up the keyboard.

Specified by:

cleanup in class BaseHeadlessApp
