```csharp
public static Object ObjectField(Object obj, Type objType, params GUILayoutOption[] options)
```

### Parameters

**** (\[Object]\(/engine/6000.7/script-reference/unityengine/object)): The object the field shows.**** (\[Type]\(https\://learn.microsoft.com/dotnet/api/system.type)): The type of the objects that can be assigned.**** (\[GUILayoutOption\[]]\(/engine/6000.7/script-reference/unityengine/guilayoutoption)): An optional list of layout options that specify extra layout properties. Any values passed in here will override settings defined by the `style`. Additional Resources: [GUILayout.Width](/engine/6000.7/script-reference/unityengine/guilayout/width.md), [GUILayout.Height](/engine/6000.7/script-reference/unityengine/guilayout/height.md), [GUILayout.MinWidth](/engine/6000.7/script-reference/unityengine/guilayout/minwidth.md), [GUILayout.MaxWidth](/engine/6000.7/script-reference/unityengine/guilayout/maxwidth.md), [GUILayout.MinHeight](/engine/6000.7/script-reference/unityengine/guilayout/minheight.md), [GUILayout.MaxHeight](/engine/6000.7/script-reference/unityengine/guilayout/maxheight.md), [GUILayout.ExpandWidth](/engine/6000.7/script-reference/unityengine/guilayout/expandwidth.md), [GUILayout.ExpandHeight](/engine/6000.7/script-reference/unityengine/guilayout/expandheight.md).

### Returns

| Type                                                            | Description                               |
| --------------------------------------------------------------- | ----------------------------------------- |
| [Object](/engine/6000.7/script-reference/unityengine/object.md) | The object that has been set by the user. |

### Remarks

You can assign objects either by drag and drop 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 the example in the [Editor](/engine/6000.7/script-reference/unityeditor/editor.md) class for further information.

*Search for a help page by selecting the GameObject in the Object Field.*

```csharp
// EditorScript that quickly searches for a help page
// about the selected Object.
//
// If no such page is found in the Manual it opens the Unity forum.

using UnityEditor;
using UnityEngine;
using System.Collections;

public class ExampleClass : EditorWindow
{
    public Object source;

    [MenuItem("Example/ObjectField Example _h")]
    static void Init()
    {
        var window = GetWindowWithRect<ExampleClass>(new Rect(0, 0, 165, 100));
        window.Show();
    }

    void OnGUI()
    {
        EditorGUILayout.BeginHorizontal();
        source = EditorGUILayout.ObjectField(source, typeof(Object), true);
        EditorGUILayout.EndHorizontal();

        if (GUILayout.Button("Search!"))
        {
            if (source == null)
                ShowNotification(new GUIContent("No object selected for searching"));
            else if (Help.HasHelpForObject(source))
                Help.ShowHelpForObject(source);
            else
                Help.BrowseURL("https://forum.unity3d.com/search.php");
        }
    }
}
```

You can also use the `options` parameter to change the look of the control. The following example changes the look of a Sprite ObjectField that is displayed with a large field format.

    }

    void OnGUI()
    {
        sprite = EditorGUILayout.ObjectField(sprite, typeof(Sprite), false, GUILayout.Height(EditorGUIUtility.singleLineHeight)) as Sprite;
    }

Additional Resources: [GUILayout.Width](/engine/6000.7/script-reference/unityengine/guilayout/width.md), [GUILayout.Height](/engine/6000.7/script-reference/unityengine/guilayout/height.md), [GUILayout.MinWidth](/engine/6000.7/script-reference/unityengine/guilayout/minwidth.md), [GUILayout.MaxWidth](/engine/6000.7/script-reference/unityengine/guilayout/maxwidth.md), [GUILayout.MinHeight](/engine/6000.7/script-reference/unityengine/guilayout/minheight.md), [GUILayout.MaxHeight](/engine/6000.7/script-reference/unityengine/guilayout/maxheight.md), [GUILayout.ExpandWidth](/engine/6000.7/script-reference/unityengine/guilayout/expandwidth.md), [GUILayout.ExpandHeight](/engine/6000.7/script-reference/unityengine/guilayout/expandheight.md).

### Returns

| Type                                                            | Description                               |
| --------------------------------------------------------------- | ----------------------------------------- |
| [Object](/engine/6000.7/script-reference/unityengine/object.md) | The object that has been set by the user. |

### Remarks

You can assign objects either by drag and drop 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 the example in the [Editor](/engine/6000.7/script-reference/unityeditor/editor.md) class for further information.
