Earlier today, I asked for help regarding how to avoid collision between two instantiated gameobjects.

With my limited understanding on programming, perhaps a question on the general use of it was a bit over my head.

Instead, please help me by looking at my code, poor as it may be, and help me with my problem.

I need to make Missile and Enemy ignore collision with each other.

using UnityEngine;

using System.Collections;

public class EnemyBehaviour : MonoBehaviour {

public GameObject Missile;
public GameObject Player;
public float enemySpeed;
private int health;
private float time;
private int shotFired;
private float shotTimer;

void OnCollisionEnter(Collision target)
{
    if(target.transform.name == "Bullet(Clone)")
    {
       health--;
    }
}

// Use this for initialization
void Start () {
health = 3;
    time = Time.deltaTime;
    shotFired = 0;
}

// Update is called once per frame
void Update () {

    if(PlayerBehaviour.playerHeight - transform.position.y >=0.3)
    {
    transform.Translate(-15f * time,10f * time,0);
    }
    else if(PlayerBehaviour.playerHeight - transform.position.y <=-0.3)
    {
    transform.Translate(-15f * time,-10f * time,0);
    }
    else
    {
    transform.Translate(-15f * time,0,0);
    }

    shotTimer += 1 * Time.deltaTime;

    if(shotTimer >= 0.4 && shotFired == 0)
    {

       shoot();

    }

    if(transform.position.x < -40)
    {
       Destroy(gameObject);
    }

    if(health<=0)
    {
       Destroy (gameObject);
    }

}

void shoot()
{

    if(shotFired == 0)
    {

    Instantiate(Missile, new Vector3(transform.position.x+3,transform.position.y,transform.position.z),Quaternion.identity);


    shotFired = 1; 
    }
}

}

That is for the Enemy

using UnityEngine;

using System.Collections;

public class MissileBehaviour : MonoBehaviour {

private float heightSpeed;
private int directionSet;
private float fireTime;


void OnCollisionEnter(Collision other)
{
    if(other.transform.name == "Ship")
    {
    Application.LoadLevel("Menu");
    }
}

// Use this for initialization
void Start () {

    directionSet = 0;

}

// Update is called once per frame
void Update () {
fireTime += 1 * Time.deltaTime;

if(PlayerBehaviour.playerHeight != 0)
    {

    if(directionSet == 0)
    {

       heightSpeed = -((PlayerBehaviour.playerHeight - transform.position.y)/(PlayerBehaviour.playerX - transform.position.x-2));
       directionSet = 1;

    }

    if(fireTime >= 1.0)
       {
         transform.Translate (-100f*Time.deltaTime,heightSpeed*100*Time.deltaTime,0);
       }

    }

}

}

That is for the missile
