public class Firework

extends Canvas

implements Runnable

Version:

1.0, Nov 26, 1996

Author:

Symantec

AnimationSpeed

Speed at which animation occurs.

Gravity

Controls gravity of the firework simulation.

MaxRocketExplosionEnergy

Controls "energy" of firwork explosion.

MaxRocketNumber

Maximum number of rockets.

MaxRocketPatchLength

Controls the radius of the firework burst.

MaxRocketPatchNumber

Controls the density of the firework burst.

RocketStyleVariability

Chance of different rocket style.

symantec.itools.multimedia.Firework()

Construct the defalut firework.

addNotify()

Tells this component that it has been added to a container.

freezeRockets()

Suspend the firework animation.

hide()

Makes this component invisible.

paint(Graphics)

Paints a black background for this firework.

removeNotify()

Tells this component that it is being removed from a container.

reshape(int, int, int, int)

Moves and/or resizes this component.

run()

Firework thread body.

show()

Makes this component visible.

unfreezeRockets()

Resume the firework animation.

public int AnimationSpeed

Speed at which animation occurs. Delay time = 100 / AnimationSpeed. Default value 10.

public int Gravity

Controls gravity of the firework simulation. Default value 400.

public int MaxRocketExplosionEnergy

Controls "energy" of firwork explosion. Default value 850.

public int MaxRocketNumber

Maximum number of rockets.

public int MaxRocketPatchLength

Controls the radius of the firework burst. Larger numbers give larger radius. Default value 68.

public int MaxRocketPatchNumber

Controls the density of the firework burst. Larger numbers give higher density. Default value 90.

public int RocketStyleVariability

Chance of different rocket style. Rocket sytle changes if Math.random() * 100 < RocketStyleVariability. Default Value 10.

public Firework()

Construct the defalut firework.

public void addNotify()

Tells this component that it has been added to a container. This is a standard Java AWT method which gets called by the AWT when this component is added to a container. Typically, it is used to create this component's peer. It has been overridden here to start the launcher thread.

Overrides:

addNotify in class Canvas

See Also:

removeNotify

public void freezeRockets()

Suspend the firework animation.

public synchronized void hide()

Makes this component invisible. This is a standard Java AWT method which gets called to hide this component. A hidden component cannot be seen by the user nor does it take up space in its container, but it does continue to exist.

Overrides:

hide in class Component

See Also:

show

public void paint(Graphics g)

Paints a black background for this firework. This is a standard Java AWT method which typically gets called by the AWT to handle painting this component. It paints this component using the given graphics context. The graphics context clipping region is set to the bounding rectangle of this component and its <0,0> coordinate is this component's top-left corner.

Parameters:

g - the graphics context used for painting

Overrides:

paint in class Canvas

See Also:

repaint, update

public synchronized void removeNotify()

Tells this component that it is being removed from a container. This is a standard Java AWT method which gets called by the AWT when this component is removed from a container. Typically, it is used to destroy the peers of this component and all its subcomponents. It has been overridden here to stop the launcher thread.

Overrides:

removeNotify in class Component

See Also:

addNotify

public synchronized void reshape(int x,
                                 int y,
                                 int width,
                                 int height)

Moves and/or resizes this component. This is a standard Java AWT method which gets called to move and/or resize this component. Components that are in containers with layout managers should not call this method, but rely on the layout manager instead.

Parameters:

x - horizontal position in the parent's coordinate space

y - vertical position in the parent's coordinate space

width - the new width

height - the new height

Overrides:

reshape in class Component

public void run()

Firework thread body. This method is called by the Java virtual machine is response to the program's call to the start method of this thread.

public synchronized void show()

Makes this component visible. This is a standard Java AWT method which gets called to show this component. If this component was invisible due to a previous hide() call it make this component visible again.

Overrides:

show in class Component

See Also:

hide

public void unfreezeRockets()

Resume the firework animation.
