static function ObjectField (position : Rect, obj : Object, objType : System.Type, allowSceneObjects : boolean) : Object

static function ObjectField (position : Rect, label : String, obj : Object, objType : System.Type, allowSceneObjects : boolean) : Object

static function ObjectField (position : Rect, label : GUIContent, obj : Object, objType : System.Type, allowSceneObjects : boolean) : Object

Parameters

Returns

Object - The object that has been set by the user.

Description

Make 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.

//Select the dependencies of the found GameObject

class EditorGUIObjectField extends EditorWindow {
    
    var obj : GameObject = null;
    
    @MenuItem("Examples/Select Dependencies")
    static function Init () {
        var window = GetWindow(EditorGUIObjectField);
        window.position = Rect(0, 0, 250, 80);
        window.Show();
    }
    
    function OnInspectorUpdate () {
        Repaint ();
    }

    function OnGUI () {        
        obj = EditorGUI.ObjectField(Rect(3,3,position.width - 6, 20),
                "Find Dependency",
                obj,
                GameObject);
        
        if (obj)    {    
            if (GUI.Button(Rect(3,25,position.width - 6, 20), "Check Dependencies"))
                Selection.objects = EditorUtility.CollectDependencies ([obj]);
        } else {
            EditorGUI.LabelField (Rect (3, 25, position.width - 6, 20),
                "Missing:", 
                "Select an object first");
        }
    }
