Best method to resume an animation from where it was interrupted

Hi all!

I hope you can help me with this. I have 2 animations: Idle and Attack. When the Attack Animation starts i want save the Idle animation's state so i can resume it after the Attack animation ends.
To do this, i wrote this code (and it actually works):

    {

        Animator anim;

        AnimatorStateInfo stateInfo;

   

        float tempNormTime;

        float prevTime;       

       

   

        private void Awake()

        {

            anim = gameObject.GetComponent<Animator>();

        }

   

        private void Update()

        {

            if (anim.GetCurrentAnimatorStateInfo(0).IsName("Idle"))

            {

                stateInfo = anim.GetCurrentAnimatorStateInfo(0);

   

                tempNormTime = stateInfo.normalizedTime;

                prevTime = tempNormTime - (float)System.Math.Truncate(tempNormTime);           

            }       

   

        }

   

        public void changeAnimation()

        {

            if (anim.GetCurrentAnimatorStateInfo(0).IsName("Idle"))

            {           

                anim.Play("Attack");

            }

            else

            {           

                anim.Play("Idle", 0, prevTime);

            }

        }

    }

Using this method, however, i can't use the Transitions in the Animator. So I ask you if there is a more effective or elegant way to do what I need. In particular, i'm looking for a way to resume the animation without using the "Play()" function but instead using an animation's Behavior.

Thank you for your time and any help!
