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.

fpsNode

protected Node fpsNode

The root node of our text.

fps

protected Text fps

Displays all the lovely information at the bottom.

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.

showBounds

protected boolean showBounds

True if the renderer should display bounds.

wireState

protected WireframeState wireState

A wirestate to turn on and off for the rootNode

lightState

protected LightState lightState

A lightstate to turn on and off for the rootNode

fontLocation

public static java.lang.String fontLocation

Location of the font for jME's text at the bottom

updateBuffer

protected java.lang.StringBuffer updateBuffer

This is used to display print text.

tempBuffer

protected java.lang.StringBuffer tempBuffer

This is used to recieve getStatistics calls.

pause

protected boolean pause

Method Detail

update

protected final void update(float interpolation)

This is called every frame in BaseGame.start()

Specified by:

update in class BaseGame

Parameters:

interpolation - unused in this implementation

See Also:

render

protected final void render(float interpolation)

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

Specified by:

render in class BaseGame

Parameters:

interpolation - unused in this implementation

See Also:
