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

Sets the rotational weight of an IK goal (0 = rotation before IK, 1 = rotation at the 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 a weight value in the range 0..1 to determine how far between the start and goal rotations the IK will aim. The goal itself is set separately using SetIKRotation.

var objToAimAt: Transform;

private var animator: Animator;


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


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