NullReferenceException: Array C#
Hi
I am getting this error "NullReferenceException: Object reference not set to an instance of an object" with this code. And I really cant see what I am doing wrong?
using UnityEngine;
using System.Collections;
public class PrefabLibrary : MonoBehaviour
{
public PrefabSettings[] prefabSettings;
public enum idPrefab
{
Storage,
DefenceTurret,
Engineering,
RecyclePlant,
WaterPlant,
BioDome,
Corridor,
Barracks,
ScienceLab,
LaunchPad,
RocketSilo,
PowerPlant
}
void Start()
{
prefabSettings = new PrefabSettings[30];
prefabSettings[1].obj = null;
}
}
public class PrefabSettings
{
public GameObject obj;
public int id;
}
Best Answer
On line 26, you create the space for the array, but each entry of the array is null. You have to initialize each entry of the array to point to a 'PrefabSettings' object. Something like:
for (int i = 0; i < prefabsSettings.Length; i++) {
prefabSettings[i] = new PrefabSettings;
}
Alternately, you could declare PrefabSettings as a struct instead of a class. As a struct, it would be a value type and would be contained in the array (rather than a reference to a class).
Thanks for the quick answer! I changed the class to a struct ins$$anonymous$$d and now it works without any errors
