# ISubgraphState

> Interface for a specialized state that references a subgraph.

## Definition

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

```csharp
public interface ISubgraphState : IState
```

## Remarks

A subgraph state acts as an entry point to another graph embedded within a [StateMachine](/engine/6000.7/script-reference/unity/graphtoolkit/editor/statemachine.md). The referenced subgraph can be either a regular [Graph](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graph.md) or another [StateMachine](/engine/6000.7/script-reference/unity/graphtoolkit/editor/statemachine.md). The owning state machine must support subgraphs through [StateMachineOptions.SupportsSubgraphs](/engine/6000.7/script-reference/unity/graphtoolkit/editor/statemachineoptions/supportssubgraphs.md).
