Constructor Detail

RigidBodyMotionState

public RigidBodyMotionState()

Instantiate a motion state.

Method Detail

applyTransform

public boolean applyTransform(Spatial spatial)

If the motion state has been updated, apply the new transform to the specified spatial.

Parameters:

spatial - where to apply the physics transform (not null, modified)

Returns:

true if changed

getWorldLocation

public Vector3f getWorldLocation()

Copy the location from this motion state.

Returns:

the pre-existing location vector (in physics-space coordinates, not null)

getWorldRotation

public Matrix3f getWorldRotation()

Read the rotation of this motion state (as a matrix).

Returns:

the pre-existing rotation matrix (in physics-space coordinates, not null)

getWorldRotationQuat

public Quaternion getWorldRotationQuat()

Read the rotation of this motion state (as a quaternion).

Returns:

the pre-existing instance (in physics-space coordinates, not null)

setVehicle

public void setVehicle(PhysicsVehicle vehicle)

Parameters:

vehicle - which vehicle will use this motion state

isApplyPhysicsLocal

public boolean isApplyPhysicsLocal()

Test whether physics-space coordinates should match the spatial's local coordinates.

Returns:

true if matching local coordinates, false if matching world coordinates

setApplyPhysicsLocal

public void setApplyPhysicsLocal(boolean applyPhysicsLocal)

Alter whether physics-space coordinates should match the spatial's local coordinates.

Parameters:

applyPhysicsLocal - true→match local coordinates, false→match world coordinates (default=false)

getObjectId

public long getObjectId()

Read the unique id of the native object.

Returns:

id (not zero)

finalize

protected void finalize()
                 throws java.lang.Throwable

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

Overrides:

finalize in class java.lang.Object

Throws:

java.lang.Throwable - ignored by the garbage collector
