SparkAnimation

public SparkAnimation(Rectangle bounds,
                      int x,
                      int y,
                      int xjog,
                      int yjog,
                      float minxvel,

                      long delay,
                      boolean fade)

Constructs a spark animation with the supplied parameters.

Parameters:

bounds - the bounding rectangle for the animation.

x - the starting x-position for the sparks.

y - the starting y-position for the sparks.

xjog - the maximum X distance by which to "jog" the initial spark positions, or 0 if no jogging is desired.

yjog - the maximum Y distance by which to "jog" the initial spark positions, or 0 if no jogging is desired.

minxvel - the minimum starting x-velocity of the sparks.

minyvel - the minimum starting y-velocity of the sparks.

maxxvel - the maximum x-velocity of the sparks.

maxyvel - the maximum y-velocity of the sparks.

xacc - the x axis acceleration, or 0 if none is desired.

yacc - the y axis acceleration, or 0 if none is desired.

images - the spark images to be animated.

delay - the duration of the animation in milliseconds.

fade - do the fade thing

Method Detail

fastForward

public void fastForward(long timeDelta)

Description copied from class: AbstractMedia

Called when the appropriate media manager has been paused for some length of time and is then unpaused. Media should adjust any time stamps that are maintained internally forward by the delta so that time maintains the illusion of flowing smoothly forward.

Overrides:

fastForward in class AbstractMedia

tick

public void tick(long timestamp)

Description copied from class: AbstractMedia

Called periodically by this media's manager to give it a chance to do its thing.

Specified by:

tick in class AbstractMedia

Parameters:

timestamp - a time stamp associated with this tick. Note: this is not obtained from a call to System.currentTimeMillis() and cannot be compared to timestamps obtained there from.

paint

public void paint(Graphics2D gfx)

Description copied from class: AbstractMedia

Called by the appropriate manager to request that the media render itself with the given graphics context. The media may wish to inspect the clipping region that has been set on the graphics context to render itself more efficiently. This method will only be called after it has been established that this media's bounds intersect the clipping region.

Specified by:

paint in class AbstractMedia
