Unable to set IK position with an offset, it keeps jittering.
I have a character holding a stick with left hand. I am using IK to make the stick hit a target position. When I position left hand at target position, it works fine. But, I need to offset the hand such that the end of the stick hits the target position. For this, I have put an empty game object as a child at the end of the stick, and offset it like below, but the hand just keeps jittering like crazy. I know it is quite possible to do that, but somehow I seem to be missing something. Please help me!
[SerializeField] private GameObject target;
private Vector3 leftHandPosition;
private Vector3 hitChildPosition;
private void OnAnimatorIK(int layerIndex)
{
Vector3 t = target.transform.position - (hitChildPosition - leftHandPosition);
animator.SetIKPosition(AvatarIKGoal.LeftHand, t);
animator.SetIKPositionWeight(AvatarIKGoal.LeftHand, 1);
}
private void LateUpdate()
{
hitChildPosition = BatHit.transform.position;
leftHandPosition = animator.GetBoneTransform(HumanBodyBones.LeftHand).position;
}
Check out this image below, I want the Hit Point Position to be placed at Target Position.
