Interface using

[ArturGimbarr75]

Can we use interface there?

example:
public interface IHitable
{
void Hit(float damage);
}

… .TryGetComponent(out IHitable hitable) …

Add it to every object we can hit

[Brian_Trotter]

Yes, this would be a good use case for an interface… In this case, since both are using Damage

public interface IHitable
{
    void Damage(float damage);
}

And then

if(collider.TryGetComponent(out IHitable hitable) //The compiler will infer the <IHitable> for the TryGetComponent based on the out Parameter
{
    hitable.Damage(damageAmount);
}

I actually did this, but I called it IDestructable

public interface IDestructable
{
    Vector3 GetWorldPosition();
    void DealDamage(int damage);
}

I added GetWorldPosition (which is probably unnecessary) because I calculated damage based on the distance from the grenade explosion, for example

if (collider.TryGetComponent(out IDestructable destructable))
{
    var damage = CalculateDamageBasedOnDistance(_targetPosition, destructable.GetWorldPosition());
    destructable.DealDamage(damage);
}
