# DiscardChanges()

> Discards unsaved changes to the contents of the editor.

## Definition

* **Type:** Method
* **Namespace:** [UnityEditor](/engine/6000.0/script-reference/unityeditor.md)
* **Assembly:** UnityEditor

```csharp
public virtual void DiscardChanges()
```

### Remarks

Override DiscardChanges() to discard unsaved work when an editor is closed. When you override this method, call the base implementation. Otherwise the [\_hasUnsavedChanges](/engine/6000.0/script-reference/unityeditor/editor/hasunsavedchanges.md) property is not reset to false. Note, if the Editor has multiple prompts to the user to discard their changes, the Editor will call this method as part of a list of changes that need to be discarded. If this method throws an exception, Unity cancels the discard process for all remaining prompts. In that case, a dialog box displays an error message with the exception message.

### Examples

```csharp
using UnityEngine;
using UnityEditor;

[CreateAssetMenu]
public class UnsavedChangesExampleSO : ScriptableObject
{}

[CustomEditor(typeof(UnsavedChangesExampleSO))]
public class UnsavedChangesExampleEditor : UnityEditor.Editor
{
    void OnEnable()
    {
        saveChangesMessage = "This editor has unsaved changes. Would you like to save?";
    }

    void OnInspectorGUI()
    {
        saveChangesMessage = EditorGUILayout.TextField(saveChangesMessage);

        EditorGUILayout.LabelField(hasUnsavedChanges ? "I have changes!" : "No changes.", EditorStyles.wordWrappedLabel);
        EditorGUILayout.LabelField("Try to change selection.");

        using (new EditorGUI.DisabledScope(hasUnsavedChanges))
        {
            if (GUILayout.Button("Create unsaved changes"))
                hasUnsavedChanges = true;
        }

        using (new EditorGUI.DisabledScope(!hasUnsavedChanges))
        {
            if (GUILayout.Button("Save"))
                SaveChanges();

            if (GUILayout.Button("Discard"))
                DiscardChanges();
        }
    }

    public override void SaveChanges()
    {
        // Your custom save procedures here

        Debug.Log($"{this} saved successfully!!!");
        base.SaveChanges();
    }

    public override void DiscardChanges()
    {
        // Your custom procedures to discard changes

        Debug.Log($"{this} discarded changes!!!");
        base.DiscardChanges();
    }
}
