Use abstract class to reference multiple scripts with different names that inherit from that abstract class

Questions & Answers
1

I have a combato system setup as follows:

Player has a script that access the enemy script and call a TakeDamage(damage) function by doing somethign like:

public GameObject Enemy;

Enemy.GetComponent<EnemyScript>().TakeDamage(damage)

The problem is that I have different EnemyScripts (with different names), and I do not want to write a lot of similar command for each enemyscript.

Question:
Can I use an abstract class to reference the enemyscripts?
I would create an abstract class and have all the enemyscripts inherit from it. Is unity gonna be happy with me using
Enemy.GetComponent<EnemyAbstractClass>().TakeDamage(damage) ?

Im already implementing interfaces (ITakeDamage) in the enemyscripts, could I use those as a reference? Thereforre I would write something like this:

Enemy.GetComponent<ITakeDamage>().TakeDamage(damage) ?

You cannot use GetComponent with interfaces, but base abstract class will do the job as long as You have only one script on GameObject that inherits from EnemyAbstractClass.

Note:
You can use the [DisallowMultipleComponent] on EnemyAbstractClass to be sure that you wont have two of them.
