Constructor Details

ConeCollisionShape

protected ConeCollisionShape()

No-argument constructor needed by SavableClassUtil.

ConeCollisionShape

public ConeCollisionShape(float radius,
 float height,
 int axisIndex)

Instantiate a cone shape around the specified main (height) axis.

Parameters:

radius - the desired unscaled radius (≥0)

height - the desired unscaled height (≥0)

axisIndex - which local axis to use for the height: 0→X, 1→Y, 2→Z (default=1)

ConeCollisionShape

public ConeCollisionShape(float radius,
 float height)

Instantiate a cone shape, oriented along the local Y axis.

Parameters:

radius - the desired unscaled radius (≥0)

height - the desired unscaled height (≥0)

Method Details

getAxis

public int getAxis()

Return the main (height) axis of the cone.

Returns:

the axis index: 0→X, 1→Y, 2→Z

getHeight

public float getHeight()

Return the height of the cone.

Returns:

the unscaled height (≥0)

getRadius

public float getRadius()

Return the radius of the cone's base.

Returns:

the unscaled radius (≥0)

unscaledVolume

public float unscaledVolume()

Return the unscaled volume of the cone.

Returns:

the volume (in shape units cubed, ≥0)

canScale

public boolean canScale(com.jme3.math.Vector3f scale)

Test whether the specified scale factors can be applied to this shape. For cone shapes, base scaling must be uniform.

Overrides:

canScale in class CollisionShape

Parameters:

scale - the desired scale factor for each local axis (may be null, unaffected)

Returns:

true if applicable, otherwise false

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 scaled shape extends from its center of mass, including collision margin.

Overrides:

maxRadius in class CollisionShape

Returns:

the distance (in physics-space units, ≥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

write

public void write(com.jme3.export.JmeExporter exporter)
           throws IOException

Serialize this shape to the specified exporter, for example when saving to a J3O file.

Specified by:

write in interface com.jme3.export.Savable

Overrides:

write in class CollisionShape

Parameters:

exporter - (not null)

Throws:

IOException - from the exporter
