Declaration

public void SetIKPositionWeight(AvatarIKGoal goal, float value);

Parameters

goal The AvatarIKGoal that is set.
value The translative weight.

Description

Sets the translative weight of an IK goal (0 = at the original animation before IK, 1 = at the goal).

An IK goal is a target position and rotation for a specific body part. Unity can calculate how to move the part toward the target from the starting point (ie, the current position and rotation obtained from the animation).

This function sets a weight value in the range 0..1 to determine how far between the start and goal positions the IK will aim. The position itself is set separately using SetIKPosition.

using UnityEngine;

public class Example : MonoBehaviour { public Transform objToPickUp; Animator animator;

void Start() { animator = GetComponent<Animator>(); }

void OnAnimatorIK(int layerIndex) { // Retrieves the value of the parameter "RightHandReach" that must be created in the AnimatorController. float reach = animator.GetFloat("RightHandReach");

// Sets IK Position and IK Position Weight. animator.SetIKPositionWeight(AvatarIKGoal.RightHand, reach); animator.SetIKPosition(AvatarIKGoal.RightHand, objToPickUp.position); } }
