Build Graphs with the Graph Editor

​

Create a Graph

You still need to create a ScriptableObject for your graph. In the Project tab, right‑click and choose “Create > Inworld > Graph > Default” or “Character Interaction”.

​

Fill in Required Fields

Do not open the Graph Editor yet. First, fill in some required fields, otherwise the graph will not run. The Default Graph is suitable for general tasks that are not related to character interaction. You can also inherit from Default Graph to implement more customized functionality. UserData is required. The Character Interaction Graph inherits from Default Graph. It is a template focused on character interaction. In addition to UserData, it has a mandatory field: CharacterData. If you plan to use a TTS node, also fill in the Voice ID. If you plan to use an LLM node, provide a Prompt. Once these are set, you can open the Graph Editor.

​

Zoom in Zoom out and Move Graph

You can scroll the mouse wheel to zoom in and zoom out. You can press and hold the mouse wheel to move around.

​

Create a Node

After opening the Graph Editor, right‑click inside the canvas and select Create Node. You can add an Inworld node, or open Custom Nodes to add an existing custom node.

​

Create a New Custom Node Type

While adding a node, you can also select Create New Custom Node Script. A dialog will appear asking for a file name and a path. Click Create to proceed. If the IDE configured for your Unity Editor is already open, it will switch to that IDE and open the newly created file. After that, reopen the Graph Editor and you will find your new custom node under Custom Nodes.

​

Create an Edge

Drag from an output port of one node to an input port of another node to automatically create an edge. You can also drag out from an output port into empty space. The editor will open the Create Node dialog; after you select a node to create, an edge will be created automatically between the two nodes.

​

Change Edge Type

Right‑click an edge to choose its type.

​

Delete Nodes or Edges

Select an edge and either Right‑click > Delete or press the Delete key. Select a node and press the Delete key to remove it.

​

Save the Graph

Click Save Graph in the top left to save your changes to the current graph. You can also press “Ctrl + S” to do the same. After saving, ScriptableObjects for the nodes and edges are generated under Assets/Data/{Your graph name}. The Start and End nodes are also computed and set automatically.

​

Export JSON

You can also click Save Json to generate a JSON representation of the graph.
