ScriptableObject not loading from AssetBundle

Hey there,

I've run into a small snag, and I was wondering if this was a bug or if perhaps I just did something wrong. I'm running Unity 5.3.1p4. Essentially, when I try to load the ScriptableObject, I get a warning "The referenced script on this Behaviour (Game Object '<null'>) is missing!" and the object is null. Here's the object:

Code (csharp):

1.  
2. using UnityEngine;
3.  
4. public class TestSerializeClassUnity : ScriptableObject
5. {
6.     [SerializeField]
7.     private Vector3[] m_Vertices;
8.  
9.     public void Initialize()
10.     {
11.         m_Vertices = new Vector3[10000];
12.     }
13. }
14.  

Then the code that builds/load the asset bundle.

Code (csharp):

1.  
2. using System;
3. using System.Collections;
4. using UnityEngine;
5.  
6. #if UNITY_EDITOR
7. using UnityEditor;
8. #endif
9.  
10. public class AssetBundlePerfTest : MonoBehaviour
11. {
12.     private static readonly string c_szBundlePath = Application.dataPath + "/TestAssets/testBundle.bun";
13.  
14. #if UNITY_EDITOR
15.  
16.     [MenuItem("Test/Prepare")]
17.     private static void PrepareTest()
18.     {
19.         AssetDatabase.CreateFolder("Assets", "TestAssets");
20.  
21.         // prepare the Unity asset  and bundle that we will use to test Unity performance
22.         TestSerializeClassUnity unityAsset = TestSerializeClassUnity.CreateInstance<TestSerializeClassUnity>();
23.         unityAsset.Initialize();
24.         AssetDatabase.CreateAsset(unityAsset, "Assets/TestAssets/CoreAsset.asset");
25.         BuildPipeline.BuildAssetBundle(null, new UnityEngine.Object[] { unityAsset }, c_szBundlePath, BuildAssetBundleOptions.UncompressedAssetBundle);
26.     }
27.  
28. #endif
29.  
30.     private void Start()
31.     {
32.         StartCoroutine(UnityPerfTest());
33.     }
34.  
35.     private IEnumerator UnityPerfTest()
36.     {
37.         AssetBundleCreateRequest req = AssetBundle.LoadFromFileAsync(c_szBundlePath);
38.         while (!req.isDone)
39.             yield return null;
40.  
41.         AssetBundleRequest loadRq = req.assetBundle.LoadAssetAsync("coreasset.asset");
42.         while (!loadRq.isDone)
43.             yield return null;
44.  
45.         TestSerializeClassUnity obj = (TestSerializeClassUnity)loadRq.asset;
46.  
47.         req.assetBundle.Unload(true);
48.     }
49. }
50.  

I've also tried loading all of the assets, and the resulting array is empty. Anyone have any thoughts, or shall I go ahead and file a bug report?

 

Update: I've tested the above scripts in several other versions of 5.x, and all of them had the same issue. I guess I'll have to work around this.

 

Okay, it seems using the "CollectDependencies" flag causes this to work just fine. Not sure why you need to collect dependencies on a single asset like this, but who am I to judge Would be nice if the warning was more helpful though.
