Constructor Detail

HullCollisionShape

protected HullCollisionShape()

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

HullCollisionShape

public HullCollisionShape(Mesh mesh)

Instantiate a collision shape based on the specified JME mesh. For best performance and stability, use the mesh should have no more than 100 vertices.

Parameters:

mesh - a mesh on which to base the shape (not null, at least one vertex)

HullCollisionShape

public HullCollisionShape(float[] points)

Instantiate a collision shape based on the specified array of coordinates.

Parameters:

points - an array of coordinates on which to base the shape (not null, not empty, length a multiple of 3)

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

createShape

protected void createShape()

Instantiate the configured shape in Bullet.

getPoints

protected float[] getPoints(Mesh mesh)

Copy the vertex positions from a JME mesh.

Parameters:

mesh - the mesh to read (not null)

Returns:

a new array (not null, length a multiple of 3)
