creating prefabs in array
hi, i get an error message stating that the array index is out of range. i need help on where am i making mistake. please explain me wat is the error. i have only one gameobject and i want only that object to be instantiated in loop.
using UnityEngine;
using System.Collections;
public class spawner_1 : MonoBehaviour {
//public GameObject card;
//public GameObject card2;
public GameObject[] prefabPool = new GameObject[1];
// Use this for initialization
void Start () {
prefabCreation ();
//prefabPool = new GameObject[2];
}
// Update is called once per frame
void Update () {
}
public void prefabCreation()
{
//print ("method start");
for(int i = 0; i < 4; i++)
{
//print(i);
for(int j = 0; j < 4; j++)
{
Vector3 position = new Vector3((j * transform.localScale.x) -1.0f, (j * transform.localScale.y) + 1, 0);
Instantiate(prefabPool[i],position, Quaternion.identity );
}
}
}
}
on line 9 you create an array of two elements while in the the for loop on line 27 you try to access the first 4 elements of that array
thanks for the response. i tried myself and figured out what is the mistake.
Array index out of range means that you are trying to access a position in the array, that does not exist.
Put in some debug lines that check: 1. How big your array truthfully is 2. Where you are at in terms of accessing it.
// First, check how big the array truthfully is...
int a = prefabpool.Length;
You should note that even you have 7 items in your array as an example.... Then the array starts at 0 and ends at 6. Arrays always start at zero
print (a);
print (i); // Check which spot in the array you really are trying to use
