# Subgraph node
|
||||
|
||||
Use a Subgraph node to reference and trigger another Script Graph's logic from inside a parent Script Graph.
|
||||
|
||||

|
||||
|
||||
For more information on Subgraphs, see [Subgraphs and State Units](vs-nesting-subgraphs-state-units.md). For more information on Script Graphs, see [Graphs](vs-graph-types.md).
|
||||
|
||||
## Fuzzy finder category
|
||||
|
||||
The Subgraph node is in the **Nesting** category in the fuzzy finder.
|
||||
|
||||
You can go to the **Graphs** category and select any Script Graph to create a Subgraph node. For more information on how to create a Subgraph, see [Add a Subgraph to a Script Graph](vs-nesting-add-subgraph.md).
|
||||
|
||||
## Available ports
|
||||
|
||||
By default, a Subgraph node has no ports.
|
||||
|
||||
Use the [Graph Inspector](vs-interface-overview.md#the-graph-inspector) to specify the following on a Script Graph:
|
||||
|
||||
- Trigger Inputs.
|
||||
- Trigger Outputs.
|
||||
- Data Inputs.
|
||||
- Data Outputs.
|
||||
|
||||
These determine the type and number of ports available on its Subgraph node. For more information on how to define ports on a Script Graph, see [Add a Trigger or Data port to a Script Graph](vs-nesting-add-triggers-data-graph.md).
|
||||
|
||||
| **Port type** | **Description** |
|
||||
| :------------- | :-------------------- |
|
||||
| **Trigger Input** | Adds a control input port to the Subgraph node for the Script Graph. Use a Trigger Input to choose which node or nodes from a parent graph triggers Visual Scripting to run the logic in the Subgraph. |
|
||||
| **Trigger Output** | Adds a control output port to the Subgraph node for the Script Graph. Use a Trigger Output to choose which node or nodes Visual Scripting triggers after the logic contained in the Subgraph finishes. |
|
||||
| **Data Input** | Adds a data input port to the Subgraph node for the Script Graph. Use a Data Input to receive data from a parent graph. |
|
||||
| **Data Output** | Adds a data output port to the Subgraph node for the Script Graph. Use a Data Output to send data back to a parent graph. |
|
||||
|
||||
## Example graph usage
|
||||
|
||||
> [!TIP]
|
||||
> A Subgraph node can use a new blank Script Graph or an existing Script Graph from a project. For more information, see [Add a Subgraph to a Script Graph](vs-nesting-add-subgraph.md).
|
||||
|
||||
In the following example, the Subgraph node **Character Move** references a graph that makes a GameObject move based on a user's input. It has the following:
|
||||
|
||||
- One Trigger Input port.
|
||||
- One Trigger Output port.
|
||||
- Three Data Input ports.
|
||||
- One Data Output port.
|
||||
|
||||
After every Update Event in the application, the **Character Move** Subgraph node triggers and takes the X, Y, and Z coordinates of the current GameObject's Transform component. The Subgraph node then outputs a new Vector 3 value, which the parent graph assigns to the current GameObject with a Transform Set Position node.
|
||||
|
||||

|
||||
|
||||
The Subgraph node reduces the number of nodes in the parent graph.
|
||||
|
||||
> [!TIP]
|
||||
> To see the Script Graph attached to the Subgraph node in this example, see either [Input node](vs-nesting-input-node.md) or [Output node](vs-nesting-output-node.md).
