Unity animation spiral effect

Let´s go!  Using your unity engine create a new game object to your scene. I will call "myGameObject".

Add to game object a sprite render with any sprite:

Now, create a new C# script, I called him "SpiralAnim.cs".

At vars declaration put:

    float timeCounter = 0;
    float speed;
    float width;
    float height;
    float deep;

In your Start() method put: 

        speed = 3;
        width = 6;
        height = 3;
        deep = 50;

In your Update() method put:

        if(this.GetComponent<SpriteRenderer>().enabled == false)
        {
            this.GetComponent<SpriteRenderer>().enabled = true;
        }

        if (transform.localScale.x>0)
        {
            timeCounter += Time.deltaTime * speed;

            float x = Mathf.Cos(timeCounter) * width;
            float y = Mathf.Sin(timeCounter) * height;
            float z = timeCounter * deep;

            transform.position = new Vector3(x, y, 0);
            transform.localScale -= new Vector3(0.01f, 0.01f, 0);
            transform.rotation = Quaternion.Euler(0, 0, z);
        }
        else
        {
            Destroy(this.gameObject);
        }

And to finish, add the script to your game object, run the scene and see the final result.

Tip: change the values of variables: speed, width, height and deep until custom to your need.
