Hello,
I’ve created a series of assets, all deriving from a BaseNode abstract class that inherits from ScriptableObject.
Everytime I open Unity and go in play mode, these assets don’t load correctly. If I open a CustomEditor that loads those assets, it cannot find anything. But if I focus the asset in the project folder (either with left click or right click) and refresh the window, the object appears correctly and gets loaded in play mode AND every asset that is referenced by it works.
I have to do this everytime I open Unity.
Is there any reason why this happens, and how can I avoid having to click on every object?
Thanks in advance!
The problem is that you should not use Resources.FindObjectsOfTypeAll() to retrieve assets, especially at run-time, because they may not necessarily end up in your build if you do it this way. In the Editor, these assets are loaded in lazily, which is why it works after you have clicked on them once.
Instead, your component should serialize references to the nodes directly, as this will cause them to be included in the build and be loaded when your component is loaded in the scene. For example:
using System.Collections.Generic;
using UnityEngine;
class MyComponent : MonoBehaviour
{
// assign these in the Inspector
[SerializeField]
List<BaseNode> m_AllNodes = new List<BaseNode>();
}
If you need to find these objects in your project at edit time (e.g., in some custom editor window) you should instead use AssetDatabase.FindAssets():AssetDatabase.FindAssets("t:BaseNode");
