Hello. I'm trying to imitate what was explained on the [Unite 11 Intro to Editor Scripting][1] on a ScriptableObject class. The class contain an array of another "class of the class".
Example :
public class A : ScriptableObject
{
[System.Serializable]
public class B
{
public B()
{
}
Rect rectangle;
Vector2 position;
}
public A()
{
myArray = new B[1];
myArray[0] = new B();
}
private B[] myArray;
}
With this class, the serialization works like a charm.
Now, I have an EditorWindow wich I use to populate my A's with some B's. For that, following the Unite 11 video, I use a SerializedObject and access its properties with SerializedObject.FindProperty(), like that :
public class AEditor : EditorWindow
{
private SerializedObject myObject;
public void SetA(A a)
{
myObject = new SerializedObject(a);
}
public void OnGUI()
{
if(myObject == null)
return;
myObject.Update();
A.B[] bs = GetBs();
// Do stuff
myObject.ApplyModifiedProperties();
}
private A.B[] GetBs()
{
int arraySize = myObject.FindProperty("myArray.Array.size").intValue;
A.B[] bs = new A.B[arraySize];
for(int i = 0; i < arraySize; i++)
{
Object o = myObject.FindProperty(string.Format ("myArray.Array.data[{0}]", i)).objectReferenceValue;
if(o == null)
{
Debug.LogError ("Object not found in array.");
continue;
}
A.B b = o as A.B;
if(b == null)
{
Debug.LogError("B object not loaded");
continue;
}
bs[i] = b;
}
return bs;
}
}
With this, The script won't compile because of line 23 "A.B b = o as A.B;", I have this :
> error CS0039: Cannot convert type 'UnityEngine.Object' to 'A.B' via a built-in conversion
So, I made B inherit from System.Object :
public class A : SerializedObject
{
public class B : UnityEngine.Object
{
...
}
...
}
Here, FindProperty find my Bs as UnityEngine.Object, but when I try to cast them, I got a null.
> B object not loaded
Here is my question : how should I declare my class B so it can be found by FindProperty() AND be castable afterward?
