Question Is there any way to set an animation as the default state from the code?

I'm trying to make a game and I need to change the default animation for another from the code. Is there any way to do this?



In the code I have this:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class WaterBucketController : MonoBehaviour {

public Animator animator;
private void OnTriggerEnter2D(Collider2D collision) //WHEN U TOUCH THE WATER BUCKET IT GETS DESTROYED AND IT CHANGES THE DEFAULT ANIMATION (WHAT I'M TRYING TO DO)
{
Destroy(gameObject, 0.1f);
}
}


Thank you!
