Serializedproperty assignment

Questions & Answers

question is at the end of the post

I have the following structure in my code.

[Serializable]
public class SomeClass : ScriptableObject{
    public OtherClass[] others;
}

[Serializable]
public class OtherClass{
    public string name;
    // .... 
    public static OtherClass GenerateOtherClass(){ /* .... */ }
}

and there is a Custom Editor for SomeClass

[CustomEditor(typeof(SomeClass))]
public class SomeClassEditor : UnityEditor.Editor {
    public override void OnInspectorGUI() {
        var others = serializedObject.FindProperty("others");    
        // ....
        if (GUILayout.Button("Generate")) {
            var o = OtherClass.GenerateOther();
            /** append o to 'others' **/
        }
        // ....
        sobj.ApplyModifiedProperties();
    }
}

I want to add a new OtherClass object to the list of others. note: OtherClass is not a ScriptableObject

edit
to clarify, the question is how do i get every variable/field/member of a Serializable-Object into a Serializeableproperty (structure) without listing every element manually
end-edit
would be cool if someone knows a solution for this.

You could use SerializedProperty.InsertArrayElementAtIndex. Note that this will insert an empty object to the array at given index.

if (GUILayout.Button("Generate"))
{
    int newIndex = others.arraySize;
    others.InsertArrayElementAtIndex(newIndex);
    /* you can get the SerializedProperty of your new object using
    "others.GetArrayElementAtIndex(newIndex);" if you need to */
}

Well i think i got it myself. Maybe theres some nicer solution. but here is mine:

 private void fillPropertyFromObject(SerializedProperty property, object o) {
            if(! o.GetType().IsSerializable) throw new ArgumentException("object is not Serializable");

            var it = property.Copy();
            it.NextVisible(true);
            var d = it.depth;
            do {
                var field = o.GetType().GetField(it.name);
                switch (it.propertyType) {
                    case SerializedPropertyType.Generic: 
                        break;
                    case SerializedPropertyType.Integer:
                        it.intValue = (int) field.GetValue(o);
                        break;
                    case SerializedPropertyType.Boolean:
                        it.boolValue = (bool)field.GetValue(o);
                        break;
                    case SerializedPropertyType.Float:
                        it.floatValue = (float)field.GetValue(o);
                        break;
                    case SerializedPropertyType.String:
                        it.stringValue = (string)field.GetValue(o);
                        break;
                    default:
                        throw new NotImplementedException();
                }
            } while(it.NextVisible(false) && it.depth >= d);
        }
