> Provides functionality needed to access, and perform operations on, state machine assets.

## Definition

* **Type:** Class
* **Namespace:** [Unity.GraphToolkit.Editor](/engine/6000.7/script-reference/unity/graphtoolkit/editor.md)
* **Assembly:** UnityEditor

```csharp
public static class StateMachineDatabase
```

## Remarks

The `StateMachineDatabase` class is the [StateMachine](/engine/6000.7/script-reference/unity/graphtoolkit/editor/statemachine.md) counterpart of [GraphDatabase](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphdatabase.md). Use this class to create, load, and save [StateMachine](/engine/6000.7/script-reference/unity/graphtoolkit/editor/statemachine.md) instances and their associated assets.

Use [StateMachineDatabase.PromptInProjectBrowserToCreateNewAsset](/engine/6000.7/script-reference/unity/graphtoolkit/editor/statemachinedatabase/promptinprojectbrowsertocreatenewasset.md) to create and name a new asset, [StateMachineDatabase.CreateStateMachine](/engine/6000.7/script-reference/unity/graphtoolkit/editor/statemachinedatabase/createstatemachine.md) to generate an asset file, and [StateMachineDatabase.LoadStateMachine](/engine/6000.7/script-reference/unity/graphtoolkit/editor/statemachinedatabase/loadstatemachine.md) to retrieve an existing one.

Use [StateMachineDatabase.SaveStateMachine](/engine/6000.7/script-reference/unity/graphtoolkit/editor/statemachinedatabase/savestatemachine.md) to persist state machine data changes, and [StateMachineDatabase.LoadStateMachineForImporter](/engine/6000.7/script-reference/unity/graphtoolkit/editor/statemachinedatabase/loadstatemachineforimporter.md) to load a clean instance during import.
