Enemy attacked state

I'll post this as an answer. Then I guess when you do your attack you can send a message to the enemy to play that animation, and that's it. :)

So if player is doing attack "fistAttack1" you send a message to the enemy script to play the animation called "fistAttack1Reaction" or something.

You can do that using the SendMessage() function or GetComponent(componentName) and then instructing the component you just got to activate the reaction.

Here's the unity reference links: :)

GetComponent http://docs.unity3d.com/Documentation/ScriptReference/Component.GetComponent.html

EDIT:

Seeing as you're using collisions to detect attack, and because I'm not sure how your attack script is actually set up, and because it isn't as simple to get the name of the current animation playing, because there can be multiple animations playing at the same time on one object, I'll write this script using strings to see which attack is active. You could use booleans but then you'd need more variables and you'd have more enabling/disabling work. There's probably better ways of doing it, and also my script might have typos or bugs cause I cant test it atm. In any case you'll learn as you go. I commented a lot to explain best I can what's going on

PlayerScript

 var currentAttack : String;

 function Update()
 {
     if(Input.GetButtonDown("Attack1")
     {
         //Set the currentAttack variable to "Attack1"
         currentAttack = "Attack1"
         //using crossfade to transition the animations smoothly
         //0.2 is the length of the animation transition (fade)
         animation.CrossFade("Attack1", 0.2); 
         //The rest of your attack code goes here
     }
     else if(Input.GetButtonDown("Attack2")
     {
         currentAttack = "Attack2"
         animation.CrossFade("Attack1", 0.2); 
     }
 }
 
 function OnCollisionEnter(coll : Collision)
 {
     if(coll.gameObject.tag == "Enemy") //check if its the enemy you hit
     {
         //check if you're using "Attack1"
         if(currentAttack == "Attack1")
         {
             //Get the enemy script from the collision data
             //We're calling your enemy script EnemyAI just for example
             var enemyScript = coll.gameObject.GetComponent(EnemyAI);
             enemyScript.attackReaction = "Attack1";
             //That will tell the EnemyAI script
             //that its being attacked by "Attack1"
         }
         else if(currentAttack == "Attack2") //or attack2
         {
             var enemyScript = coll.gameObject.GetComponent(EnemyAI);
             enemyScript.attackReaction = "Attack2";
         }
     }
 }

EnemyAI

 var attackReaction : String;
 
 function Update()
 {
     //Check if the attackReaction is "Attack1" or "Attack2" 
     //set by the PlayerScript with GetComponent
     if(attackReaction == "Attack1")
     {
         //Play your animation called "Attack1Reaction" for example
         animation.CrossFade("Attack1Reaction", 0.2);
         if(!animation.isPlaying("Attack1Reaction")
         {
             //If its done playing set attackReaction to "None" or something, to end the loop.
             //Otherwise itll probably continue repeating
             //youll see, im just writing not testing because
             //i dont have any animations to work with atm xD
             attackReaction = "None";
         }
     }
     else if(attackReaction == "Attack2") //or attack2
     {
         animation.CrossFade("Attack2Reaction", 0.2); 
         if(!animation.isPlaying("Attack2Reaction")
         {
             attackReaction = "None";
         }
     }
 }
