EditorGUI.ObjectField

Obsolete public static Object ObjectField(Rect position, Object obj, Type objType);

Obsolete public static Object ObjectField(Rect position, string label, Object obj, Type objType);

Obsolete public static Object ObjectField(Rect position, GUIContent label, Object obj, Type objType);

public static Object ObjectField(Rect position, Object obj, Type objType, bool allowSceneObjects);

public static Object ObjectField(Rect position, string label, Object obj, Type objType, bool allowSceneObjects);

public static Object ObjectField(Rect position, GUIContent label, Object obj, Type objType, bool allowSceneObjects);

Parameters

position		Rectangle on the screen to use for the field.
label		Optional label in front of the field.
obj		The object the field shows.
objType		The type of the objects that can be assigned.
allowSceneObjects		Allow assigning Scene objects. See Description for more info.

Returns

Object The object that has been set by the user.

Description 描述

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 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");
    }

Parameters
