How can I lerp animator layer weights in/out?

Questions & Answers

My player’s arms snap into place when the aim key is pressed. How can I use lerp to increase or decrease the upperbody’s weight so his upper body doesnt just snap into position but happens more gradually?

 void Actions()
    {
        if (Input.GetKeyDown(KeyCode.F))
        {
            aim = !aim;
            if (aim == true)
            {
                anim.SetLayerWeight(1, 1);
                aimik.solver.SetIKPositionWeight(1);
            }
            else
            {
                anim.SetLayerWeight(1,0);
                aimik.solver.SetIKPositionWeight(0);
            }
        }

I know this thread is a few months old

but, all that needs to be done is to call the 2 functions to so that you can swap between them.

Also, this is applying to layer 1 of the animator. The indexes start from 0 and go up so basically im lerping from the base layer to the next layer.

These links will help you better understand what is going on.

using UnityEngine;
using System.Collections;

public class SetLayerWeight : MonoBehaviour {

	public Animator animator;
	public float smoothTime;
	private float yVelocity = 0.0F;
	private float currWeight;
	
	public void Update()
	{
		currWeight = animator.GetLayerWeight(1);
	}
	
	
	public void UnarmedActive ()
	{
		float startWeight = Mathf.SmoothDamp(currWeight, 1.0f, ref yVelocity, smoothTime);
		animator.SetLayerWeight(1, startWeight); 
	}
	
	public void UnarmedInactive ()
	{
		float endWeight = Mathf.SmoothDamp(currWeight, 0.0f, ref yVelocity, smoothTime);
		animator.SetLayerWeight(1, endWeight); 
	}
}
