2D character animation not working in Unity. Why?

Question

C++ / C#

I'm making a 2D game on Unity 5.6. Faced a problem - the animation does not work. I use Animation and did everything right: installed Legacy, etc. I call the animation in the code like this:

if (Input.GetKeyDown (KeyCode.Space)) {
        GetComponent<Animation>().Play ("my_animation_name");
}

But she doesn't lose. There are no errors in the console. Does anyone have any ideas?

Answer 1

you can try without if (Input.GetKeyDown (KeyCode.Space)) { }

Answer 2

Personally, I implemented animation in a different way:
public Animator Animator1;
Animator1.Play("my_animation_name");
on the animator you hang an object with an installed animator, inside of which your animation already lies
