# GetCorrespondingObjectFromSource<TObject>(TObject)

> Retrieves the corresponding source prefab asset object of a given GameObject or component, or null if it can't be found.

## Definition

* **Type:** Method
* **Namespace:** [UnityEditor](/engine/6000.6/script-reference/unityeditor.md)
* **Assembly:** UnityEditor.CoreModule

## GetCorrespondingObjectFromSource\<T>(T)

```csharp
public static TObject GetCorrespondingObjectFromSource<TObject>(TObject componentOrGameObject) where TObject : Object
```

### Parameters

**** (T): The object to find the corresponding object from.

### Returns

| Type | Description                       |
| ---- | --------------------------------- |
| T    | The corresponding object or null. |

### Remarks

Use this method to get the source prefab asset object the GameObject or component was instantiated from.

For example, in the diagram shown below, prefab asset A contains a child nested prefab B, which contains a child nested prefab C.

![nested prefab instance example (GetCorrespondingObjectFromSource\<TObject>(TObject))](/api/media?file=/engine/6000.6/media/images/nested-prefab-instance-example.png)

The image shows the nested prefab assets, with B and C nested under A, and C nested under B, and how this structure carries over to their nested instances in the Hierarchy window.

In this example scenario, if you supply the instance of GameObject C as the `componentOrGameObject` parameter to `GetCorrespondingObjectFromSource`, then the method returns the object C from the asset Prefab A.

For more information about source objects, refer to [Introduction to prefabs](/engine/6000.6/manual/working-with-gameobjects/prefabs/introduction.md).

The following example adds a menu item to the Editor, which launches a simple wizard that allows you to test the results of this method.

```csharp
using UnityEditor;
using UnityEngine;
public class AssetSourceTestWizard : ScriptableWizard
{
    public GameObject instance;

    [MenuItem("Test/Asset Source Test Wizard")]
    static void CreateWizard()
    {
        ScriptableWizard.DisplayWizard<AssetSourceTestWizard>("Asset Source Test Wizard", "Do Test");
    }

    void OnWizardCreate()
    {
        var o1 = PrefabUtility.GetCorrespondingObjectFromSource(instance);
        Debug.Log("Corresponding object from source: " + o1.name + " from: " + AssetDatabase.GetAssetPath(o1));
    }
}
```
