Constructor Summary

FloatingTextAnimation(Label label, int x, int y)
Constructs an animation for the given text centered at the given coordinates.

FloatingTextAnimation(Label label, int sx, int sy, int destx, int desty, long floatPeriod)
Constructs an animation for the given text starting at the given coordinates and floating toward the specified coordinates.

FloatingTextAnimation(Label label, int x, int y, long floatPeriod)
Constructs an animation for the given text centered at the given coordinates.

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	flipDirection() Called to change the direction 180 degrees.
Label	getLabel() Returns the label used to render this score animation.
void	paint(Graphics2D gfx) Called by the appropriate manager to request that the media render itself with the given graphics context.
protected void	paintLabels(Graphics2D gfx, int x, int y) Derived classes may wish to extend score animation and render more than just the standard single label.
void	setFloatPeriod(long floatPeriod) Sets the duration of this score animation to the specified time in milliseconds.
void	setLocation(int x, int y) Set the location.
void	tick(long timestamp) 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

FloatingTextAnimation

public FloatingTextAnimation(Label label,
                             int x,
                             int y)

Constructs an animation for the given text centered at the given coordinates.

FloatingTextAnimation

public FloatingTextAnimation(Label label,
                             int x,
                             int y,
                             long floatPeriod)

Constructs an animation for the given text centered at the given coordinates. The animation will float up the screen for 30 pixels.

FloatingTextAnimation

public FloatingTextAnimation(Label label,
                             int sx,
                             int sy,
                             int destx,
                             int desty,
                             long floatPeriod)

Constructs an animation for the given text starting at the given coordinates and floating toward the specified coordinates.

Method Detail

flipDirection

public void flipDirection()

Called to change the direction 180 degrees.

getLabel

public Label getLabel()

Returns the label used to render this score animation.

setLocation

public void setLocation(int x,
                        int y)

Description copied from class: AbstractMedia

Set the location.

Overrides:

setLocation in class Animation

setFloatPeriod

public void setFloatPeriod(long floatPeriod)

Sets the duration of this score animation to the specified time in milliseconds. This should be called before the animation is added to the animation manager.

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.

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

paintLabels

protected void paintLabels(Graphics2D gfx,
                           int x,
                           int y)

Derived classes may wish to extend score animation and render more than just the standard single label.

Parameters:

x - the upper left coordinate of the animation.

y - the upper left coordinate of the animation.

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
