AnchorConstraint

---

An anchor act as sort of elastic attached to the center of node on a soft body in other word a typical point to point constraint. Depending on the total mass to of the body and influence of the anchor the soft body will be either pulled or dragged toward the anchor's attachment point.

The anchor contains two attach point; the first (pivotA) is always relative to the current object transformation. The second (pivotB) depend if an existing RigidBody is attached to the constraint. If there is one connected the point is relative to the object location; instead the second attach point is relative to the first.

Static Variables

---

Name	Description
softconstraint	The SoftConstraint reference the current anchor belongs to.
Declaration SoftConstraint *softconstraint

Variables

---

Name	Description
pivotA	The first anchor attach point.
Declaration vec3 pivotA Note The attach point will automatically snap to the closest node of the SoftBody.
pivotB	The second anchor attach point.
Declaration vec3 pivotB Note If the anchor rigidbody property have been assigned to an existing RigidBody the pivotB is relative to is PhysicObject transformation; else the first attach point.
rigidbodyB	An existing rigidbody that belongs to the same World.
Declaration RigidBody *rigidbodyB Note To disconnect the rigidbodyB set it property to nil.
collision_between_bodies	Enable or disable the collision between the two physics bodies.
Declaration bool collision_between_bodies Note This option only take effect if the anchor rigidbodyB is set.
enabled	Enable or disable the constraint.
Declaration bool enabled Remarks When disabled the constraint will still remain in the World however it will not processed by the solver.
influence	Represent how much the softbody is affected by the pulling effect of the anchor.
Declaration float influence Range 0.0 to 10.0 \note The higher the influence the faster the soft body will be "pulled" toward the pivotB. \warning The suggested range of influence is between 0.0 and 10.0 other values exceeding that range might make the soft body unstable. </td>

Functions

Name	Description
GetNodeInfo	Retrieve information about the SoftBody node connected to the constraint.
Declaration NodeInfo GetNodeInfo( void ) Return Value Upon failure return a zeroed NodeInfo structure; else return a fully filled structure that contains the node information.
