when I assign vectors to the array, the will not be carried over to the rocketUpdate function. The Gene array that is being used comes from an other script running on the gameObjects from the rocket array. This is the script it is from.

using System.Collections;

using System.Collections.Generic;

using UnityEngine;



public class Rockets : MonoBehaviour {



    public Vector2 Gene;



    public void Start()

    {

        Gene = new Vector2[10];

    }

}

this is the main "controller" script.

using System;

using System.Collections;

using System.Collections.Generic;

using UnityEngine;



public class RocketController : MonoBehaviour {



    public int XVelocityMultiplier;

    public int YVelocityMultiplier;



    int lifespanSec;



    int Count;



    public int Size;

    public GameObject rockets;

    public GameObject RocketPrefab;



    public System.Random rnd = new System.Random();

    float x;

    float y;



    void Start()

    {

        rockets = new GameObject[Size];



        lifespanSec = RocketPrefab.GetComponent<Rockets>().Gene.Length;



        Invoke("killRockets", lifespanSec);



        for (int i = 0; i < rockets.Length; i++)

        {

            GameObject rocketObject = Instantiate(RocketPrefab);

            rocketObject.GetComponent<Rigidbody>().position = new Vector3(0, -4, 30);

            rocketObject.name = "Rocket_" + (i+1);



            for (int j = 0; j < rocketObject.GetComponent<Rockets>().Gene.Length; j++)

            {

                x = Convert.ToSingle(rnd.NextDouble() * (2 * XVelocityMultiplier) + XVelocityMultiplier * (rnd.Next(-1,1) + 0.1f));

                y = Convert.ToSingle(rnd.NextDouble() * (YVelocityMultiplier));

                rocketObject.GetComponent<Rockets>().Gene[j] = new Vector2(x, y);

                Debug.Log(rocketObject.GetComponent<Rockets>().Gene[j]);

            }

            rockets[i] = rocketObject;



        }

        InvokeRepeating("RocketUpdate", 0, 1);

    }



    void Update()

    {

        if (Count == lifespanSec)

        {

            Count = 0;

        }

    }



    void RocketUpdate()

    {

        Debug.Log(rockets[1].GetComponent<Rockets>().Gene[Count]);

        if (rockets[0] != null)

        {

            for (int i = 0; i < rockets.Length; i++)

            {

                rockets[i].GetComponent<Rigidbody>().velocity = rockets[i].GetComponent<Rockets>().Gene[Count];

            }

            Debug.Log(rockets[1].GetComponent<Rockets>().Gene[Count]);

        }

        Debug.Log(Count);

        Count++;

    }



    void killRockets()

    {

        for(int i = 0; i < rockets.Length; i++)

        {

            Destroy(rockets[i]);

        }

    }

}

when I run the first Debug.log() in the start function, every gameObject has its values. but when I run the same Debug.log in rocketUpdate() it suddenly doesn't have its values anymore. I have been stuck on the same problem for a long time. if anyone knows the problem please do tell.

Several things. In your first script you aren't populating an array with a bunch of values, you are creating a new array with space for 10 Vector2s. I'm not sure if that's what you want, but it's what it is. In order to populate it with data, you have to explicitly tell it what the data should be by creating a reference to the script holding the actual values. For example,

private MainScript whateverYouWannaCallIt;

private Vector2 geneCopies; 



public void Awake()

{

    whateverYouWannaCallIt = gameObject.GetComponent<MainScript>();



    for (int i = 0; i < whateverYouWannaCallIt.rockets.Length; i++)

    {

        geneCopies[i] = whateverYouWannaCallIt.rockets.gene[i];

    }

}

You should also initialize a List and populate it with those rockets and maybe one for the rigidbodies as well, those getComponent calls are gonna contribute a lot to your overhead.

Also, I'm intrigued. What is your goal with this script? And what's your game about?
