Constructor Details

DeformableSpace

public DeformableSpace(com.jme3.math.Vector3f worldMin,
 com.jme3.math.Vector3f worldMax,
 PhysicsSpace.BroadphaseType broadphaseType,
 SolverType solverType)

Instantiate a DeformableSpace with the specified contact-and-constraint solver. Must be invoked on the designated physics thread.

Parameters:

worldMin - the desired minimum coordinate value for each axis (not null, unaffected, default=(-10k,-10k,-10k))

worldMax - the desired maximum coordinate value for each axis (not null, unaffected, default=(10k,10k,10k))

broadphaseType - which broadphase accelerator to use (not null)

solverType - the desired constraint solver (not null)

Method Details

countSoftBodies

public int countSoftBodies()

Count the soft bodies in this space.

Returns:

the count (≥0)

getDeformableSpace

public static DeformableSpace getDeformableSpace()

Access the DeformableSpace running on this thread. For parallel physics, this may be invoked from the OpenGL thread.

Returns:

the pre-existing DeformableSpace running on this thread

getSoftBodyList

public Collection<PhysicsSoftBody> getSoftBodyList()

Enumerate soft bodies that have been added to this space and not yet removed.

Returns:

a new unmodifiable collection of pre-existing instances (not null)

getWorldInfo

public SoftBodyWorldInfo getWorldInfo()

Access the parameters applied when soft bodies are added to this space.

Returns:

the pre-existing instance (not null)

addCollisionObject

public void addCollisionObject(PhysicsCollisionObject pco)

Add the specified collision object to this space.

Overrides:

addCollisionObject in class PhysicsSpace

Parameters:

pco - the collision object to add (not null)

contains

public boolean contains(PhysicsCollisionObject pco)

Test whether the specified collision object is added to this space.

Overrides:

contains in class MultiBodySpace

Parameters:

pco - the object to test (not null, unaffected)

Returns:

true if currently added, otherwise false

countJoints

public int countJoints()

Count the joints in this space, including anchors and soft-body joints.

Overrides:

countJoints in class PhysicsSpace

Returns:

the count (≥0)

create

protected void create()

Must be invoked on the designated physics thread.

Overrides:

create in class MultiBodySpace

destroy

public void destroy()

Remove all collision objects and physics joints.

Overrides:

destroy in class MultiBodySpace

getPcoList

public Collection<PhysicsCollisionObject> getPcoList()

Enumerate collision objects that have been added to this space and not yet removed.

Overrides:

getPcoList in class MultiBodySpace

Returns:

a new modifiable collection of pre-existing instances (not null)

isEmpty

public boolean isEmpty()

Test whether this space is empty.

Overrides:

isEmpty in class MultiBodySpace

Returns:

true if empty, otherwise false

removeCollisionObject

public void removeCollisionObject(PhysicsCollisionObject pco)

Remove the specified collision object from this space.

Overrides:

removeCollisionObject in class PhysicsSpace

Parameters:

pco - the collision object to remove (not null)

setGravity

public void setGravity(com.jme3.math.Vector3f gravity)

Alter the gravitational acceleration acting on newly-added bodies.

Typically, when a body is added to a space, the body's gravity gets set to that of the space. Thus, it is preferable to set the space's gravity before adding any bodies to the space.

Overrides:

setGravity in class PhysicsSpace

Parameters:

gravity - the desired acceleration vector (not null, unaffected, default=(0,-9.81,0))
