General class for all script-classes?

My problem is that in my game i have three different enemies, a skeleton, a skeleton mage and a scorpion. On each of those i have a common script called "EnemyBaseScript". This script checks by name which enemy it is and calls "Scorpion.function", "Skeleton.function" or "SkeletonMage.function" with a switch case.

private void attackPlayer()
{
switch (Enemy_)
{
case 1:
StartCoroutine(SkeletonNormal.attack());
break;

case 2:
StartCoroutine(SkeletonMage.attack());
break;

case 3:
StartCoroutine(Scorpion.attack());
break;
}
}

I think this makes bad performance, especially if i would like to expand my game with say 10 different enemies?
- Is there a way to have general class for all the scripts so i can do something like this:

private commonClass thisEnemy;

if(this.name == "Skeleton")
{
thisEnemy = this.getComponent<SkeletonScript>();
}
else if(this.name == "Scorpion")
{
thisEnemy = this.getComponent<ScorpionScript>();
}

 

Inheritance and or interfaces.

Thanks for the answer. I have seen the links but i still don't see how my problem can be solves using inheritance and/or interfacing? Can you give me a more detailed answer?
- Thanks

 

Code (csharp):

1.  
2. public abstract class BaseEnemy
3. {
4.     public abstract void Attack();
5. }
6.  
7. public class Skeleton: BaseEnemy
8. {
9.     override public void Attack()
10.     {
11.         //Skeletonattack code
12.     }
13. }
14.  
15. public class Scorpion: BaseEnemy
16. {
17.     override public void Attack()
18.     {
19.         //Scorpionattack code
20.     }
21. }
22.  

Then you can do something like:

Code (csharp):

1.  
2. BaseEnemy enemy;
3.  
4. gameObject.GetComponent<BaseEnemy>().Attack();
5.  
6.  

 

Oh i see! - Thanks a lot Guzzo, really helped me!
