# Attach a graph file to a Script Machine or State Machine
|
|
|
|
To use a Script Graph or State Graph file in your project, you need to attach it to a Script Machine or State Machine.
|
|
|
|
A Script Machine or State Machine is a component. Components attach to GameObjects, and help define their behavior. For more information on components and GameObjects, see [the Unity User Manual on using components](https://docs.unity3d.com/2021.1/Documentation/Manual/UsingComponents.html), or [the section on GameObjects](https://docs.unity3d.com/2021.1/Documentation/Manual/GameObjects.html).

|
|
## Add a Script Machine or State Machine component to a GameObject
|
|
|
|
1. In the Editor's Hierarchy window, select a GameObject where you'd like to add a Script Machine or State Machine.
|
|
If the Hierarchy window isn't visible, go to **Window** > **General** > **Hierarchy** or press CTRL + 4 (macOS: Cmd + 4).
|
|
|
|
2. (Optional) If the Inspector window for your selected GameObject doesn't appear, press CTRL + 3 (macOS: Cmd + 3), or go to **Window** > **General** > **Inspector**.
|
|
|
|
3. In the GameObject's Inspector window, select **Add Component**.
|
|
The Components menu opens.
|
|
|
|
4. To add a Script Machine or State Machine, in the Components menu, go to **Visual Scripting** and select **Script Machine** or **State Machine**. Or, use the search bar to find the Script Machine or State Machine component.
|
|
|
|
The new Script Machine or State Machine component appears in the Inspector window for your GameObject:

|
## Attach a graph file to the Script Machine or State Machine
|
|
|
|
1. In the Inspector window, locate your Script Machine or State Machine component, and ensure that you set the **Source** to **Graph**.
|
|
|
|
2. In the **Graph** field, select the target icon and choose a compatible graph file from your project.
|
|
|
|
You can also click and drag a file from your Project window and drop it into the **Graph** field to attach a graph to the component. For more information on how to create Script or State Graphs, see [Creating a new graph file](vs-create-graph.md).

## Next steps

After you attach a graph to a Script Machine or State Machine, you can open your graph for editing. For more information, see [Open a graph file for editing](vs-open-graph-edit.md).
