Constructor Detail

GImpactCollisionShape

protected GImpactCollisionShape()

No-argument constructor needed by SavableClassUtil. Do not invoke directly!

GImpactCollisionShape

public GImpactCollisionShape(Mesh mesh)

Instantiate a shape based on the specified JME mesh.

Parameters:

mesh - the Mesh to use

Method Detail

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.

Note that if the shape is shared (between collision objects and/or compound shapes) changes can have unintended consequences.

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.

finalize

protected void finalize()
                 throws java.lang.Throwable

Finalize this shape just before it is destroyed. Should be invoked only by a subclass or by the garbage collector.

Overrides:

finalize in class CollisionShape

Throws:

java.lang.Throwable - ignored by the garbage collector
