Stores the current pose for an IK constraint. Stores the current pose for an IK constraint. An IK constraint adjusts the rotation of 1 or 2 constrained bones so the tip of the last bone is as close to the target bone as possible. See [url=http://esotericsoftware.com/spine-ik-constraints]IK constraints[/url] in the Spine User Guide. Updates the constraint. The IK constraint is solved by adjusting the rotation of the bones so the tip of the last bone is as close to the target as possible. Returns the IK constraint's setup pose data. Returns the bones that will be modified by this IK constraint. Modifying the array has no effect. Returns the bone that is the target for the IK constraint. The bones will be rotated so the tip of the last bone is as close to the target as possible. Sets the bone that is the target for the IK constraint. The bones will be rotated so the tip of the last bone is as close to the target as possible. Returns the current pose for this IK constraint, containing mix, softness, bend direction, compress, and stretch values. Returns the applied pose for this IK constraint. Returns whether this IK constraint is active. When inactive, the constraint is not applied. Sets whether this IK constraint is active. When inactive, the constraint is not applied.
