Question Calling animation states from code

Hi
I promise I have been trying to find the answer to this but I think it is too simple to be covered. So hoping someone here can help

I have two animation states:
sittingidle
talking

When the user chooses the avatar they should switch from sittingidle to talking and when they lose focus it should return to the sittingidle pose

I have set up a controller with both states; sittingidle is default and this plays correctly on my avatar

I have tried
public AnimationClip[] animationClips;
private RuntimeAnimatorController controller;
private Animator animator;

but can't make any of them work

How do i switch in code?

thanks

Assign the Animator Controller to the Controller field in the Animator component's Inspector.

Then call animator.Play("State Name");
