Trying to Generate Different Random Values for Position of Game Object Instances [C#]

Questions & Answers
1

I am trying to generate different random values for the position of my game object whenever it is re-instantiated. For some reasons, it is not working. Can someone help to see what is wrong? (newPosition is the value that I hope it would be different everytime a new gameobject is generated.)

using UnityEngine;
using System.Collections;

public class KillObjectGenerator : MonoBehaviour
{

    public float randomTimeDelay;
    private Vector3 newPosition;
    public float spawnTime = 3.0f;
    public GameObject cloud;
    public GameObject lightning;
    private float randomX = Random.Range(-8.3f, 0.78f);

    void Start()
    {
        randomTimeDelay = Random.Range(3f, 6f);

        // Start calling the Spawn function repeatedly after a delay.
        InvokeRepeating("Generator", randomTimeDelay, spawnTime);
    }

    void spawnNewPosition()
    {
        newPosition = new Vector3(randomX, 0.18f, 0);
    }

    void Generator()
    {
        Instantiate(cloud, newPosition, Quaternion.identity);
        Instantiate(lightning, newPosition, Quaternion.identity);
        Debug.Log("Spawned a kill object!");
    }
}

randomX is assigned a random value once during construction. You want a random value for every new spawn position. So why not move the Random assignment to inside of the spawnNewPosition() function?

void spawnNewPosition()
{
    randomX = Random.Range(-8.3f, 0.78f);
    newPosition = new Vector3(randomX, 0.18f, 0);
}
