Loading MP3's into an Audio Array and assigning them to members of a GameObject Array

Questions & Answers
1

I’m trying to load an array of MP3 files from the Resources folder, and then assign each MP3 file to the Audio Clip value of a GameObject.

This list of GameObjects (referred to as “Notes”) is sorted, and the MP3 files are already sorted manually (their names are in numerical order).

Below is my attempt, I’ve removed the sorting method SortNotes() to save space (it works perfectly fine, isn’t the issue).

    // An array of Notes
    public GameObject[] NotesArray;
    
    AudioClip[] pickupMP3s;
    
    // Use this for initialization
    void Start () {
    	// Grab and sort array of Notes
    	NotesArray = GameObject.FindGameObjectsWithTag("Note");
    	SortNotes();
    
    	// Grab a list of pick-up mp3 files
    	pickupMP3s = Resources.LoadAll("..\\Level 4\\Level 4 Pickup Tracks") as AudioClip[];
    }
    
    // Assign each mp3 file to a Note
    void AssignNotes(){
    	for (int i = 0; i < NotesArray.Length; i++){
    		foreach (GameObject note in NotesArray){
    			try{
    				note.audio.clip = pickupMP3s*;*

_ Debug.Log(pickupMP3s*);_
_ Debug.Log(note.audio.clip.name);_
_ }catch(Exception e){_
_ Debug.Log(e.ToString());_
_ }_
_ }_
_ } _
_}_
_I get tons of NullReferenceException: Object reference not set to an instance of an object errors. They seem to stem from this line: note.audio.clip = pickupMP3s; but I can’t figure out what.*
The objects already have Audio Sources attached._

It could be an issue with the cast, you could try the generic version:

Resources.LoadAll<AudioClip>(path);
