EditorWindow GameObject Array

I've been trying to find a source on how to put a gameobject array (or list) in a custom editor window that will accept multiple items dragged into it at once. Is there a simple way to do this with an ObjectField? I tried using a foreach loop, but it gives me an error.

 

So I finally was able to piece everything together, and for anyone else who might have the same problem:

Code (CSharp):

1. public class MyClass : EditorWindow{
2.  
3.     public GameObject[] someThings;
4.  
5.     [MenuItem("Window/My Class")]
6.     public static void ShowWindow(){
7.  
8.         EditorWindow.GetWindow <MyClass>("My Class");
9.     }
10.  
11.     void OnGUI(){
12.      
13.         ScriptableObject scriptableObj = this;
14.         SerializedObject serialObj = new SerializedObject (scriptableObj);
15.         SerializedProperty serialProp = serialObj.FindProperty ("someThings");
16.  
17.         EditorGUILayout.PropertyField (serialProp, true);
18.         serialObj.ApplyModifiedProperties ();
19.     }
20. }

I had seen very similar code segments around, but I didn't think they fit my use case.

What took me a while to realize was that EditorWindow derives from ScriptableObject, so I can keep everything I need in this class by referencing itself. A SerializedObject can be initialized from that, and a global variable in the class can be accessed as a SerializedProperty.

 

Thanks!
exactly what I needed

 

this is better than create a reorederablelist i've find before
