EditorGUI.ObjectField

Parameters

Returns

Object The object that has been set by the user.

Description

Makes an object field. You can assign objects either by drag and drop objects or by selecting an object using the Object Picker.

Ensure that the allowSceneObjects parameter is false if the object reference is stored as part of an asset, since assets can't store references to objects in a Scene.
If the ObjectField is part of a custom Editor for a script component, use EditorUtility.IsPersistent() to check if the component is on an asset or a Scene object.
See example in Editor class.


Object field in an Editor Window.

using UnityEditor;
using UnityEngine;
using System.Collections;

//Select the dependencies of the found GameObject
public class EditorGUIObjectField : EditorWindow
{
    public GameObject obj = null;
    [MenuItem("Examples/Select Dependencies")]
    static void Init()
    {
        UnityEditor.EditorWindow window = GetWindow(typeof(EditorGUIObjectField));
        window.position = new Rect(0, 0, 250, 80);
        window.Show();
    }

    void OnInspectorUpdate()
    {
        Repaint();
    }

    void OnGUI()
    {
        obj = (GameObject)EditorGUI.ObjectField(new Rect(3, 3, position.width - 6, 20), "Find Dependency", obj, typeof(GameObject));
        if (obj) {
            if (GUI.Button(new Rect(3, 25, position.width - 6, 20), "Check Dependencies")) {
                Selection.objects = EditorUtility.CollectDependencies(new GameObject[] {obj}); 
            }

            else {
                EditorGUI.LabelField(new Rect(3, 25, position.width - 6, 20), "Missing:", "Select an object first");
            }
        }
    }
}
