How to make an array of game objects

Question

I was wondering how I could make an array of game objects using only one image? For example, I have a picture of a cannon ball and a cannon and I want to make 10 cannon balls and be able to change each one of them individually. I have this script attached to a single cannon ball gameobject and I have made my array length 5 using the inspector.

I've tried using instantiate but all that happens is it clones it forever.

public GameObject[] cannonball;
public int i;
public int x=0;
void Start()
{
    for (i = 0; i < cannonball.Length; i++) {
        Instantiate(cannonball[i], new Vector2(x, 0), Quaternion.identity);
        x = x + 5;
    } 
}

When I do this, for some reason it continues to clone game objects and I don't know why.

I'm curious if it's on a cannonball, if it's on a cannon, or something else. — Ruzihm

This script is on my cannon ball. I have a cannon gameobject in place and every time I press space I want it to fire a cannon ball. If I press space lets say 3 times, you can see 3 cannon balls moving across the screen. — Trucing

You attached this script to a canonball GameObject. This means that everytime you fire a canonball, this will have the script attached to it as well and spawn a new canonball spawning a new canonball... You can see the loop here.

You should not attach this to a canonball prefab, but rather on for example a GameController object.

I haven't tested it, but to do this, create a new GameObject in your scene and attach your script to it after removing it from your cannonball GameObject..Now if you press space you can instantiate the cannonballs.

public GameObject[] cannonball;
public int i;
public int x=0;

void Update()
{
    if (Input.GetKeyDown(KeyCode.Space)) {
        for (i = 0; i < cannonball.Length; i++) {
            Instantiate(cannonball[i], new Vector2(x, 0), Quaternion.identity);
            x = x + 5;
        }
    } 
}

How can I do this

@Trucing Put the script on literally anything else besides your prefab.

Okay, and how can I make each of the cloned objects an image in my array through the inspector?

Or how can I move an instantiated object?
