IKChainBlueprint

public class IKChainBlueprint

Represents a complete IK chain definition from a Blockbench model. An IK chain consists of: - A series of bones from root (ik_source) to tip - A target position (from a locator or bone) - A controller (null object) that animates the chain The chain is built by walking UP from the target to the source bone, then reversing to get root-to-tip order (as Blockbench does).

Constructors

IKChainBlueprint

public void IKChainBlueprint(List<BoneBlueprint> chainBones, LocatorBlueprint targetLocator, NullObjectBlueprint controller)

Creates an IK chain with a locator as the target.

public void IKChainBlueprint(List<BoneBlueprint> chainBones, BoneBlueprint targetBone, NullObjectBlueprint controller)

Creates an IK chain with a bone as the target.
