Hey guys.

. What I'm attempting to do (and having little success with) is to sort the script so that when the enemy is at for example equal to a certain point i.e: -3 in the .y axis a bullet is fired.

If anyone knows the best way of doing this then I would greatly appreciate it, I'm loving unity and I'm learning quite quick, however in this case I'm confused as to why if position == (insert number here) doesn't appear to work, clearly the enemy has to cross y.3 in order to reach .y 6 for example.

Right now the script is written so that if the enemy is below a certain point then he will stop, and if his STOP position is equal to what I want then he will fire. I'm assuming that if position.y == doesn't work because the enemy is moving too fast, however I would like to get around this problem without slowing the enemy movement down.

Currently My enemy script is as follows

using UnityEngine;
using System.Collections;

public class Enemy_Script : MonoBehaviour
{
    public float MinSpeed;
    public float MaxSpeed;

    public float currentSpeed;
    private float x, y, z;
    public GameObject Projectile;
    float firingRate = 2f; //delay between shots, in seconds
    float lastFired = -100f; //absolute time of last fired shot

    // Use this for initialization
    void Start()
    {
        //currentSpeed = Random.Range(MinSpeed, MaxSpeed);
        currentSpeed = 4;
        x = Random.Range(2f, 2f);
        y = 7.0f;
        z = 0.0f;

        transform.position = new Vector3 (x, y, z);
    }

    // Update is called once per frame
    void Update()
    {
        float amtToMove = currentSpeed * Time.deltaTime;
        transform.Translate(Vector3.down * amtToMove);

        if (Time.time < lastFired + firingRate)
        {
            return;
        }


        if (transform.position.y <= -6.0)

        {
            currentSpeed = 4;
            // currentSpeed = Random.Range(MinSpeed, MaxSpeed);
            transform.position = new Vector3(x, y, z);
        }
        lastFired = Time.time;
        //if (transform.position.y <= 4f)
        if (transform.position.y <= 2f)
            //currentSpeed = Random.Range(0, 0);
        {
            Vector3 rightposition = new Vector3(transform.position.x + transform.localScale.x * -8, transform.position.y + transform.localScale.y * 5);
            Instantiate(Projectile, rightposition, Quaternion.Euler(0, 0, 90));


        }

        }
}

Thanks guys, I'm a little unsure how to stick a reward on my post, I cant see the option anywhere.
