Constructor Detail

BasicPaddle

public BasicPaddle(Board b)

Creates a BasicPaddle of a default size and location, belonging to a specified Board.

Parameters:

b - the Board object of which this BasicPaddle is a member.

Method Detail

setLocation

public void setLocation(java.awt.Point p)

Inactive. BasicPaddle manages its own location.

Specified by:

setLocation in interface BreakoutComponent

getLocation

public java.awt.Point getLocation()

Gets the current location of this BasicPaddle.

Specified by:

getLocation in interface BreakoutComponent

Returns:

a new Point object representing the current location of this BasicPaddle.

getSize

Specified by:

getSize in interface BreakoutComponent

Returns:

a new Dimension object representing the size of this BasicPaddle.

update

public void update()

Called by World every tick; does nothing.

Specified by:

update in interface BreakoutComponent

hit

public boolean hit(BreakoutComponent bc)

Called by a Rebounding BreakoutComponent when it has detected an intersection with this BasicPaddle.

Specified by:

hit in interface BreakoutComponent

Parameters:

bc - the Rebounding/BreakoutComponent object that detected the hit.

Returns:

false -- a BasicPaddle doesn't die when hit.

getShape

public java.awt.Shape getShape()

Gets the java.awt.Shape of this BasicPaddle.

Specified by:

getShape in interface BreakoutComponent

Returns:

a new Shape label at the same location and of the same size/shape as this BasicPaddle.

paint
