Coroutine working in the Unity Editor, but not when built and deployed to the Oculus Go

I have a coroutine that just triggers off a VFX and SFX on load:

Code (csharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using System.IO;
6. using System.Linq;
7. using UnityEngine.UI;
8. public class QuizManager : MonoBehaviour {
9.    
10.     [SerializeField]
11.     public List<Question> Questions;
12.     public ParticleSystem[] StartParticles;
13.     public AudioSource[] startAudio;
14.     // Use this for initialization
15.     void Start () {
16.         Questions = File.ReadAllLines("Assets/Questions.csv")
17.             .Skip(1)
18.             .Select(v => Question.FromCsv(v))
19.             .ToList();
20.         StartCoroutine (onInitLoad ());
21.     }
22.    
23.     // Update is called once per frame
24.     void Update () {
25.        
26.     }
27.     IEnumerator onInitLoad(){
28.         yield return new WaitForSecondsRealtime (2f);
29.         foreach (AudioSource a in startAudio) {
30.             a.Play ();
31.         }
32.         foreach (ParticleSystem p in StartParticles) {
33.             p.Play ();
34.         }
35.         FindObjectsOfType<Text>()[0].text = "RAN";
36.         FindObjectsOfType<Text>()[1].text = "RAN";
37.     }
38. }
39. [System.Serializable]
40. public class Question
41. {
42.     string Country;
43.     string FilePath;
44.     string Answer1;
45.     string Answer2;
46.     string Answer3;
47.     public static Question FromCsv(string csvLine)
48.     {
49.         string[] values = csvLine.Split(',');
50.         Question q = new Question();
51.         q.Country = values[0].ToString();
52.         q.FilePath = values [1].ToString ();
53.         q.Answer1 = values [2].ToString ();
54.         q.Answer2 = values [3].ToString ();
55.         q.Answer3 = values [4].ToString ();
56.         return q;
57.     }
58. }
59.  

This is triggered in the start method using StartCoroutine(onInitLoad()), this works perfectly and as expected in the Editor and Play mode., but not when built and deployed. Any ideas why? This is my whole scrip.

 

FIXED: My code wasn't finding the csv file on android - erroring and not running the coroutine.

 

I think your text file load is failing. I'm not sure, because I have never tried to load a text file just like that.
https://docs.unity3d.com/Manual/LoadingResourcesatRuntime.html

Check out your logs and it will tell you what's the problem in runtime. https://docs.unity3d.com/Manual/LogFiles.html

 

I haven't used oculus before, but I'm going to take a possible guess that it might be getting stuck on File.ReadAllLines

It's possible that like Android, oculus doesn't maintain it's file structure which means you wouldn't be able to access Assets/Questions.csv

You should put Questions.csv into StreamingAssets and access it there, although you may have to use www or unitywebrequest to access it from that location.

Nevermind, looks like it's all fixed now. lol

 

StreamingAssets? Is that just a folder?

 

https://docs.unity3d.com/Manual/StreamingAssets.html

It's a special folder that doesn't import the file (no import settings), but any file in the folder will be included in the build.

It can be accessed through Application.streamingAssetsPath as they mention in the doc. Interesting enough, I haven't really look at their doc description. It does claim the files are placed in the normal filesystem on the target.
