SKReachConstraints
A specification of the degree of freedom when solving inverse kinematics.
Declaration
class SKReachConstraintsOverview
An SKReachConstraints object is used to describe the range of motion for an SKNode object whenever an inverse kinematic (IK) action is executed. To use reach constraints, create an SKReachConstraints object and assign it to a node’s reachConstraints property. For more information on using reach actions to perform IK animations, see the SKAction class.
