Thank you very much!

Hi,

you can add this script to your dog object. Then drag your clips and objects into the right fields. Use an not animated parent object for the dog otherwise the position changes will not apply.

Call the ChangeAnim function from OnTargetFound() in your owner Image Target. Also for the Collision detection for the last animation change both objects need rigid bodies an colliders.

public AnimationClip walk;
    public AnimationClip lick;
    public GameObject dog;
    public GameObject owner;
    Animation anim;
    Vector3 direction;
    void Start()
    {
        anim = GetComponent<Animation>();
    }
    public void ChangeAnim()
    {
        anim.clip = walk;
        anim.Play();
        direction = Vector3.Normalize(owner.transform.position- dog.transform.position );
        dog.transform.SetParent(null, true);
    }
    void Update()
    {
        if(anim.clip == walk)
        {
            float speed = 0.001f;
            dog.transform.position = dog.transform.position + direction*speed;
        }
    }
    void OnCollisionEnter(Collision collision)
    {
        anim.clip = lick;
        anim.Play();
    }
