After days of looking for solutions, what's wrong with my array script?

Questions & Answers
1

I’ve tried multiple ways of writing the syntax. I’m on the verge of leaving Arrayl̶i̶s̶t̶ for rigid solutions and using list for more flexibility. Yet I have to solve this one or else I’ll feel like I’ve failed. Please help.

Only one object gets spawned and the array length stays zero.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class isolatingproblems : MonoBehaviour {

	public GameObject cube;

	int limit = 9;

	public GameObject[] arrcube;


	void spawn () 
	{
		for (int i = 0; i < limit; i++) 
		{
			GameObject cubearray = Instantiate (cube, transform.position, Quaternion.identity);

			arrcube *= cubearray;*

  •  }*

  • }*

  • void Update ()*

  • {*

  •  if (Input.GetButtonDown ("Jump"))* 

  •  {		*

  •  	spawn ();*

  •  }*

  • }*
    }

you need to initialize the array with

arrcube = new GameObject[limit];

before you can put anything into the array.
Once you call that, you get an array with 9 null elements, so you need should put it in the start method.

you didn’t initialize arrcube… in your case that would

arrcube = new GameObject[9];

Then you can iterate thorugh the for loop like this:

for (int i = 0; i < arrcube.length; i++) 
{
    code
}

Also you can use a

List<GameObject> arrcube = new List<GameObject>();

if you want the array to be flexible in size. (to hold more or less than 9).

To add a Gameobject to arrcube you’d then need to use:
arrcube.Add(cubearray);
