Populate a dropdown, consisted of list of objects

I want to populate a dropdown which would consist of a list of objects. I use the dropdown editor way for populating dropdowns in the inspector. Usually, I get a list from the main script and using it in Editor script. But now, the problem is that the list is a list of objects, from which I want to show only a value from every object in the dropdown and when is selected, to use all of its properties.

Code (CSharp):

1.  [CustomEditor(typeof(MaterialsDropdown))]
2.     public class MaterialsDropdownEditor : Editor {
3.         public override void OnInspectorGUI() {
4.             base.OnInspectorGUI();
5.  
6.             MaterialsDropdown materialsDropdownScript = (MaterialsDropdown) target;
7.             // TODO: Fix the dropdown: Get options from API
8.             GUIContent label = new GUIContent("MyList");
9.             materialsDropdownScript.listIdx =
10.                 EditorGUILayout.Popup(label, materialsDropdownScript.listIdx, materialsDropdownScript.materialsList);
11.         }
12.     }

 

I mean something like this should work:

Code (CSharp):

1. string[] options = new string[materialsDropdownScript.materialsList.length];
2. int index = 0;
3. foreach (Material material in materialsDropdownScript.materialsList)
4. {
5.    options[index++] = material.name;
6. }
7. EditorGUILayout.Popup(label, materialsDropdownScript.listIdx, options);

But i fear you have to assign the choosen object somewhere later by the selected index.

 

Thanks
