Constructor Detail

Anchor

public Anchor(PhysicsSoftBody softBodyA,
              int nodeIndexA,
              PhysicsRigidBody rigidBodyB,
              Vector3f pivotInB,
              boolean allowCollisions)

Instantiate an anchor with influence=1.

Parameters:

softBodyA - the soft body for the A end (not null, alias created)

nodeIndexA - the index of the node for the A end (≥0, <numNodes)

rigidBodyB - the rigid body for the B end (not null, alias created)

pivotInB - the pivot location in B's scaled local coordinates (not null, unaffected)

allowCollisions - true→allow collisions between the bodies, false→disallow such collisions

Method Detail

copyPivot

public Vector3f copyPivot(Vector3f storeResult)

Copy the location of the connection point in the rigid body at the B end.

Parameters:

storeResult - storage for the result (modified if not null)

Returns:

a location vector (in B's scaled local coordinates, either storeResult or a new instance)

getRigidBody

public PhysicsRigidBody getRigidBody()

Access the rigid body at the B end.

Returns:

the pre-existing body (not null)

getSoftBody

public PhysicsSoftBody getSoftBody()

Access the soft body at the A end.

Returns:

the pre-existing soft body (not null)

influence

public float influence()

Read how much influence the anchor has on the bodies.

Returns:

the amount (≥0, ≤1, 0→no influence, 1→strong influence)

isAllowCollision

public boolean isAllowCollision()

Test whether collisions are allowed between the bodies.

Returns:

true if collisions are allowed, otherwise false

nodeIndex

public int nodeIndex()

Read the index of the anchored node in body A.

Returns:

the node index (≥0)

setInfluence

public void setInfluence(float amount)

Alter how much influence the anchor has on the bodies.

Parameters:

amount - the degree of influence (≥0, ≤1, 0→no influence, 1→strong influence, default=1)

setPivotInB

public void setPivotInB(Vector3f location)

Alter the pivot location in B's local coordinates.

Parameters:

location - the desired location (not null, unaffected)

isEnabled

public boolean isEnabled()

Test whether this Anchor is enabled.

Specified by:

isEnabled in class PhysicsJoint

Returns:

true
