SphereCollisionShape

public SphereCollisionShape(float radius)

Instantiate a sphere shape with the specified radius.

Parameters:

radius - the desired radius (≥0)

Method Detail

getRadius

public float getRadius()

Read the radius of the sphere.

Returns:

the radius (≥0)

write

public void write(JmeExporter ex)
           throws java.io.IOException

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

Specified by:

write in interface Savable

Overrides:

write in class CollisionShape

Parameters:

ex - exporter (not null)

Throws:

java.io.IOException - from exporter

read

public void read(JmeImporter im)
          throws java.io.IOException

De-serialize this shape, for example when loading from a J3O file.

Specified by:

read in interface Savable

Overrides:

read in class CollisionShape

Parameters:

im - importer (not null)

Throws:

java.io.IOException - from importer

setScale

public void setScale(Vector3f scale)

Alter the scaling factors of this shape. Scaling is disabled for sphere shapes.

Overrides:

setScale in class CollisionShape

Parameters:

scale - the desired scaling factor for each local axis (not null, no negative component, unaffected, default=1,1,1)

createShape

protected void createShape()

Instantiate the configured shape in Bullet.
