Animator.SetIKRotation
SetIKRotation(goal: AvatarIKGoal, goalRotation: Quaternion): void;
void SetIKRotation(AvatarIKGoal goal, Quaternion goalRotation);
def SetIKRotation(goal as AvatarIKGoal, goalRotation as Quaternion) as void
Parameters

goal The AvatarIKGoal that is set.
goalRotation The rotation in world space.
Description

Sets the rotation of an IK 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 the rotation of the ultimate goal in world space; the actual rotation where the body part ends up is also influenced by a weight parameter that specifies how far between the start and the goal the IK should aim (a value in the range 0..1).

}


function OnAnimatorIK(layerIndex: int) {
	var handRotation = Quaternion.LookRotation(objToAimAt.position - transform.position);
	animator.SetIKRotationWeight(AvatarIKGoal.RightHand, 1.0);
	animator.SetIKRotation(AvatarIKGoal.RightHand, handRotation);
