Constructor Detail

BoundedItem

public BoundedItem(Texture t,
                   Tangible b)

Constructor for creating a BoundedItem. Automatically adds this item as a listener to the supplied Tangible item if it is a GameRelatedObject.

Parameters:

t - is the Texture to represent this item on screen

b - is the Tangible item that this object will know the bounds of

Method Detail

getRectangularBoundaries

protected java.awt.geom.Rectangle2D getRectangularBoundaries()

Method for getting the current rectangular boundaries associated with the BoundedItem. This is equivalent of calling getShape().getBounds2D().

Returns:

a Rectangle2D representing the boundaries of what is bounding this item in terms of the game's coordinate system

getShapeBoundaries

protected java.awt.Shape getShapeBoundaries()

Method for getting the current boundaries associated with the BoundedItem. These boundaries are very precise and represent the exact Shape associated with the object bounding this one.

Returns:

a Shape representing the boundaries of what is bounding this item in terms of the game's coordinate system

positionChanged

public void positionChanged(PositionChangedEvent e)

Description copied from interface: PositionChangeListener

This is called whenever a Tangible object updates its position.

Specified by:

positionChanged in interface PositionChangeListener

Parameters:

e - the PositionChangedEvent

rotationChanged

public void rotationChanged(RotationChangedEvent e)

Description copied from interface: RotationChangeListener

This is called whenever a Tangible object changes its rotation.

Specified by:

rotationChanged in interface RotationChangeListener

Parameters:

e - the RotationChangedEvent

sizeChanged

public void sizeChanged(SizeChangedEvent e)

Description copied from interface: SizeChangeListener

This is called whenever a Tangible object updates its position.

Specified by:

sizeChanged in interface SizeChangeListener

Parameters:

e - the PositionChangedEvent
