Custom editor field accepting multiple drag and drops?

Questions & Answers
1

I have a custom editor I’m using for a custom object. Right now I can drag an object into that field and immediately add it to a list as so:

customObject = EditorGUILayout.ObjectField("Drag Element Here to Add", 
	customObject, typeof(Element), false) as Element;
			
	if (customObject != null) {
		if (!objectList.Contains(customObject)) {
			objectList.Add(customObject);
			customObject = null;
		} else {
			Debug.Log(customObject.name + " is already in the list.");
			customObject = null;
		}
	}

I can’t seem to drag and drop more than one thing in, no matter what I’ve tried (like using a list customObject instead of just a single object), but I’ve seen it done (for instance with 2dTK). How?

tk2d uses a custom drag and drop area, not an objectField. You should look for DragAndDrop operations.
