All Implemented Interfaces:

java.awt.event.KeyListener, java.lang.Runnable, java.util.EventListener

public class Physics
extends java.lang.Object
implements java.lang.Runnable, java.awt.event.KeyListener

A class that handles the movement through the scene and the keyboard input.

Field Summary

private int	animStart Keeps track of what frame the current animation started on
private int	flag Determines whether to turn left (-1), turn right (1), turn around (-2 or 2) or move (0)
private int	frame Keeps track of which frame of the animation is being rendered
private int	lastFlag Keeps track of the last animation run and ensures that animStart is not constantly overwritten
(package private) static javax.vecmath.Matrix3d	m3d
private MenuPanel	menu
private boolean	modflag Determines whether or not the flag variable can be modified

Constructor Detail

Physics

public Physics(MenuPanel mp,
               World w)

Instantiates the class with the specified parent MenuPanel and World.

Method Detail

start

public void start()

Starts the thread.

stop

public void stop()

Stops the thread.

run

public void run()

This method runs the Physics processing. It is designed to run at a fixed framerate of 75fps, if such a framerate is attainable, and ensures that the JVM garbage collector does not get overloaded

Specified by:

run in interface java.lang.Runnable

move

public void move()

Moves the camera forward.

turnRight

public void turnRight()

Turns right by rotating the camera clockwise.

turnLeft

public void turnLeft()

Turns left by rotating the camera counterclockwise.

keyPressed

public void keyPressed(java.awt.event.KeyEvent ke)

Handles keyboard input. Inputs used and their respective functions detailed in the Control section of the main menu.

Specified by:

keyPressed in interface java.awt.event.KeyListener

keyTyped

public void keyTyped(java.awt.event.KeyEvent ke)

Remnant of KeyListener interface; not used.

Specified by:

keyTyped in interface java.awt.event.KeyListener

keyReleased

public void keyReleased(java.awt.event.KeyEvent ke)

Remnant of KeyListener interface; not used.

Specified by:

keyReleased in interface java.awt.event.KeyListener
