Constructor Details

EmptyShape

protected EmptyShape()

No-argument constructor needed by SavableClassUtil.

EmptyShape

public EmptyShape(boolean unused)

Instantiate an empty shape.

Parameters:

unused - to distinguish this from the no-argument constructor

Method Details

unscaledVolume

public float unscaledVolume()

Return the volume of the shape.

Returns:

0

canSplit

public boolean canSplit()

Test whether the shape can be split by an arbitrary plane.

Overrides:

canSplit in class CollisionShape

Returns:

true

cloneFields

public void cloneFields(com.jme3.util.clone.Cloner cloner,
 Object original)

Callback from Cloner to convert this shallow-cloned shape into a deep-cloned one, using the specified Cloner and original to resolve copied fields.

Specified by:

cloneFields in interface com.jme3.util.clone.JmeCloneable

Overrides:

cloneFields in class CollisionShape

Parameters:

cloner - the Cloner that's cloning this shape (not null)

original - the instance from which this shape was shallow-cloned (not null, unaffected)

maxRadius

public float maxRadius()

Calculate how far the shape extends from its center.

Overrides:

maxRadius in class CollisionShape

Returns:

0

read

public void read(com.jme3.export.JmeImporter importer)
          throws IOException

De-serialize the shape from the specified importer, for example when loading from a J3O file.

Specified by:

read in interface com.jme3.export.Savable

Overrides:

read in class CollisionShape

Parameters:

importer - (not null)

Throws:

IOException - from the importer

scaledVolume

public float scaledVolume()

Return the volume of the shape, including scale and margin.

Overrides:

scaledVolume in class CollisionShape

Returns:

0
