Boxing character and AI enemys

I have a third person (based on TornadoTwins tutorial) that can walk, rotate and shoot fire balls. On one point in my game he lossing hes ability to shoot so he have to use he's hands to fight, like boxing. how do I animate him that it will look like he hits the enemys (3 hits) and the enemys will seems like they being hit by me?

here is my character script:

//Walking 

var speed = 20.0;

var rotateSpeed = 4.0;

//Shooting
var bullitPrefab:Transform;

//Dying
private var dead = false;

//Getting hit
var tumbleSpeed = 800;
var decreaseTime = 0.01;
var decayTime = 0.01;
static var gotHit = false;
private var backup = [tumbleSpeed, decreaseTime, decayTime];

function LateUpdate()
{
     if (gotHit)
     {
         if(tumbleSpeed < 1)
         {
             //we're not hit anymore... reset & get back in the game!
             tumbleSpeed = backup[0];
             decreaseTime = backup[1];
             decayTime = backup[2];
             gotHit = false;
         }
         else
         {
             //we're hit! Spin our character around
             transform.Rotate(0, tumbleSpeed * Time.deltaTime, 0, Space.World);
             tumbleSpeed = tumbleSpeed-decreaseTime;
             decreaseTime += decayTime;
         }
     }
 }

//function OnControllerColliderHit(hit : ControllerColliderHit)
function OnTriggerEnter( hit : Collider )
{
     if(hit.gameObject.tag == "enemyProjectile")
     {
         dead = true;
         //substract life here
         HealthControl.LIVES -= 1;
         gotHit = true;
         Destroy(hit.gameObject);
     }

     if(hit.gameObject.tag == "HP_Capsule") //extra Lives
     {
         if(HealthControl.LIVES >=3)
         {
             HealthControl.LIVES +=1;
             Destroy(hit.gameObject);
         }
         else
         {
             HealthControl.LIVES = 3;
             Destroy(hit.gameObject);
         }
     }
 }

function Update ()
    {
        var controller : CharacterController = GetComponent(CharacterController);
        transform.Rotate(0, Input.GetAxis ("Horizontal") * rotateSpeed, 0);

        var forward = transform.TransformDirection(Vector3.forward);
        var curSpeed = speed * Input.GetAxis ("Vertical");

        controller.SimpleMove(forward * curSpeed);

        //Shooting!
        if(Input.GetButtonDown("Jump"))
        {
             var bullit = Instantiate(bullitPrefab, transform.Find("SpawnPointB1").transform.position, Quaternion.identity);
             bullit.tag = "bobProjectile";
             bullit.rigidbody.AddForce(transform.forward * 5000);
        }
     }

@script RequireComponent(CharacterController)

Another question i have is how to make the enemys follow after me and rotate? how to make an AI enemy?

    var distance;
    var target : Transform;    
    var lookAtDistance = 15.0;
    var attackRange = 10.0;
    var moveSpeed = 5.0;
    var damping = 6.0;
    private var isItAttacking = false;

    function Update () 
    {
    distance = Vector3.Distance(target.position, transform.position);

    if(distance < lookAtDistance)
    {
    isItAttacking = false;
    renderer.material.color = Color.yellow;
    lookAt ();
    }   
    if(distance > lookAtDistance)
    {
    renderer.material.color = Color.green; 
    }
    if(distance < attackRange)
    {
    attack ();
    }
    if(isItAttacking)
    {
    renderer.material.color = Color.red;
    }
}

function lookAt ()
{
var rotation = Quaternion.LookRotation(target.position - transform.position);
transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * damping);
}

function attack ()
{
    isItAttacking = true;
    renderer.material.color = Color.red;

    transform.Translate(Vector3.forward * moveSpeed *Time.deltaTime);
}

Here is a VERY basic AI. Just remember to drag the target you want the AI to follow in the inspector. When you come in a certan range it will look at you. If you get even closer it will attack you. I dont know if you can use this or not.

Tell me if there is something you wanna know and if you can use this.

Happy to help :)

thx. (wow, that answer was fast…).I’ll try it. I asked about the animate of the “Boxing Charecter”, can you help me with that?
