Unity动画C＃

Question

I am making abilities for a game and I need to add animations (which I know how to do). My problem is I need a way to make a reference to animations without assigning a particular animation. I have a base class along with base logic for an ability (which is where I need a general reference because an ability does need an animation) and then when I want to make an ability I make a new class that inherits the base and then create the ability that way (which is where I would assign an animation).

//Default logic for abilities
public virtual void abilityEffects(hero caster, hero target){
    this.caster = caster;
    this.target = target;
    float DMG = damage * this.caster.heroAttPow;

    //Ability should not be on cooldown the first time it is used
    if (firstUse == true)
    {

        //sets the total damage to take into account the ability damage plus the hero power
        //need general reference to animation here
        //when animation is over, deal damage
        this.target.HP -= DMG;
        firstUse = false;
        //cooldown begins
        SpellStart = Time.time;
    }

    if(firstUse == false)
    {
        if (Time.time > SpellStart + SpellCooldown)
        {
            //sets the total damage to take into account the ability damage plus the hero power
            //need general reference to animation here
            //when animation is over, deal damage
            this.target.HP -= DMG;
            //cooldown begins
            SpellStart = Time.time;
        } 
    }
}

an Animator Component controls all your object animations and states and if it is attached to your gameobject you can get a reference to it like this

public class player: MonoBehaviour { 
    public Animator anim;    
    public void Start() {
        anim = GetComponent<Animator>();
    }
}

your class can also be abstract if you want to you just should call the start of the base class in the child class to get the reference to the animator component

public abstract class player: MonoBehaviour {
    public Animator anim;    
    public void Start() {     
        anim = GetComponent<Animator>();
    }
}
public class PlayerChild: player{   
    void Start() {
        base.Start();        
    } 
}
