Prefab not loading in data from Inspector

Question

Okay. What I'm trying to do is create an array of prefabs, but I'm having trouble properly creating them and placing them in the array. I've tried several things so far, but these two actually compile and don't crash immediately:

 // 1. An array of GameObjects
 public GameObject[] Weapons;
     
 // Setting array size
 Weapons = new GameObject[(int)WeaponBase.WeaponType.NumTypes];
     
 Weapons[0] = GameObject.Find("MachineGun");

 // 2. An array of base-class scripts
 public WeaponBase[] Weapons;
     
 // Setting array size
 Weapons = new WeaponBase[(int)WeaponBase.WeaponType.NumTypes];
     
 Weapons[0] = gameObject.AddComponent<WeaponBase>();

Neither of these options assigns the values from the prefab's Inspector upon creation, but the objects do get created, and are assigned the values within their ctor. I used to be able to Instantiate this prefab before I implemented the array, but since that's not working, nothing else is.

Any help would be appreciated. Thanks!

Your Weapons array is immedialty overriden on the run by this line:

 Weapons = new GameObject[(int)WeaponBase.WeaponType.NumTypes];

Which is creating a new array... What you need to do is:

 public GameObject[] Weapons = new GameObject[(int)WeaponBase.WeaponType.NumTypes]; 
 // in the declaration you can set the size without override what is in inspector

As I'm not sure it would compile because of the (int)WeaponBase.WeaponType.NumTypes not being accesible in the declaration (I honestly don't know) the 2 alternatives you have are:

Set the size in script like this: public GameObject[] Weapons = new GameObject[12];
Set the size manually in inspector

What I ended up doing was your first bullet, the public GameObject[] Weapons = new GameObject[num];

Then I created factory methods that instantiated new weapons and placed them in their respective array slots.

What I think the problem was (sorry it took me so long to reply) was that I had ctors in the derived class attached to the prefabs, and they were being called, thus overriding what was in the inspector, even though they were empty. I took those out and just made an Init() that was called after creation. Everything works now that there's a factory. Thanks for your quick input!
