Questions & Answers

im creating a top-down shooter and i cant find a way to have the enemy shoot at the player...what im trying to do is have the enemy rotate towards the player and then shoot bullets every few seconds...this is the enemy script that i currently have...everything works fine but the firing...any ideas or suggestions pleaseeeee

     var lookAtTarget : Transform;
var speed : int;
var range : int;
var damp : float;
var ENEMY_HEALTH = 30;
var nextFire = 1;
private  var fireRate = 0.0;
var enemyBullet : Transform;
var death : Transform ;
var health : Transform;

function Awake()
{
    if (!lookAtTarget)
    {
        lookAtTarget = GameObject.FindWithTag("Player").transform;
    }
}

function Update() 
{   

    if(ENEMY_HEALTH <= 0)
    {
        Instantiate(death, transform.position, transform.rotation);
        Instantiate(health, transform.position, transform.rotation);
        Debug.Log("DEAD");
        Destroy(gameObject);
     }

    if(lookAtTarget && CanAttackTarget())
    {
        //transform.LookAt(lookAtTarget);
        var rotate = Quaternion.LookRotation(lookAtTarget.transform.position - transform.position);
        transform.rotation = Quaternion.Slerp(transform.rotation, rotate, damp); 
        transform.Translate (0,0,speed*Time.deltaTime);

        if(Time.time >= nextFire)
        {
            nextFire = Time.time + fireRate;
            var bullet = Instantiate(enemyBullet, transform.position, transform.rotation);
            bullet.rigidbody.velocity = transform.forward * speed;
        }

    }

}

function CanAttackTarget()
{
    //check if in range
    if(Vector3.Distance(transform.position, lookAtTarget.position) > range)
    {
        return false;
    }

    return true;

}

function OnParticleCollision ()
{
    Debug.Log("hit");
    ENEMY_HEALTH--;
}

Your code is almost entirely correct. 

if(Time.time >= nextFire)
{
    nextFire = Time.time + fireRate;

In your code, 'fireRate' is always going to be 0 (unless you left out some code), so you will be firing on every frame after game time passes 'nextFire' seconds. This is probably a typo -- 'fireRate' should probably be 'nextFire'.

Your movement and rotation code is correct.
