Constructor Summary

BobbleAnimation(Mirage image, int sx, int sy, int rx, int ry, int duration)
Constructs a bobble animation.

Method Summary

void	fastForward(long timeDelta) Called when the appropriate media manager has been paused for some length of time and is then unpaused.
void	paint(Graphics2D gfx) Called by the appropriate manager to request that the media render itself with the given graphics context.
void	tick(long tickStamp) Called periodically by this media's manager to give it a chance to do its thing.
protected void	toString(StringBuilder buf) This should be overridden by derived classes (which should be sure to call super.toString()) to append the derived class specific information to the string buffer.

Constructor Detail

BobbleAnimation

public BobbleAnimation(Mirage image,
                       int sx,
                       int sy,
                       int rx,
                       int ry,
                       int duration)

Constructs a bobble animation.

Parameters:

image - the image to animate.

sx - the starting x-position.

sy - the starting y-position.

rx - the horizontal bobble range.

ry - the vertical bobble range.

duration - the time to animate in milliseconds.

Method Detail

tick

public void tick(long tickStamp)

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:

tickStamp - 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.

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

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

toString

protected void toString(StringBuilder buf)

Description copied from class: AbstractMedia

This should be overridden by derived classes (which should be sure to call super.toString()) to append the derived class specific information to the string buffer.

Overrides:

toString in class AbstractMedia
