Type of Namespace Could not be found - Animation related

[Swegfan]

I’m looking to use a single animation to animate multiple objects
Error is underlined at with error code : The Type of namespace HO1could not be found, which is clearly alocated and linked in-game.

[SerializeField]
public Image Heart2;
[SerializeField]
public Animation HO1;

void Start()
{
   
    Heart2.GetComponent<HO1>().Play();

    ResetQuestion();
}

I’m sure Unity is smarter than this, and i’m just missing out on something.
Thanks guys, i couldn’t find a matching issue anywhere else.

Heart2.GetComponent<HO1>().Play();

Should be…

 Heart2.GetComponent<Animation>().Play();

if you want to play the animation on the GameObject Hearth2 reference

or…

GetComponent<Animation>().Play();

If you want to play HO1 from this GameObject

[Swegfan]

[SerializeField]
public GameObject Heart2;
[SerializeField]
public AnimationClip HO1;

    void Start()
    {


        ResetQuestion();
        Animation anim = Heart2.AddComponent<Animation>();
        anim.clip = HO1;
        anim.Play();
    }

found the answer myself, but the problem gets a bit more complicated … i’d like to animate the object the animation is attached to … any quick solution for this ?
