> The GameObject is not shown in the Hierarchy, not saved to the Scene, and not unloaded by Resources.UnloadUnusedAssets.

## Definition

* **Type:** Field
* **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```

### Remarks

This is most commonly used for GameObjects which are created by a script and are purely under the script's control.

### Examples

```csharp
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    // Creates a Material that is explicitly created & destroyed by the component.
    // Resources.UnloadUnusedAssets will not unload it, and it will not be editable by the Inspector.
    private Material ownedMaterial;
    void OnEnable()
    {
        ownedMaterial = new Material(Shader.Find("Diffuse"));
        ownedMaterial.hideFlags = HideFlags.HideAndDontSave;
        GetComponent<Renderer>().sharedMaterial = ownedMaterial;
    }

    // Objects created as hide and don't save must be explicitly destroyed by the owner of the object.
    void OnDisable()
    {
        DestroyImmediate(ownedMaterial);
    }
}
```
