Variable

Graph context-menu category: Logic. Editor menu label: Set / Modify Variable.

Variable node and dialogue graph example. Supplied product gallery image; any captions/overlays are promotional, not interactive controls. Applies Set, Add, Subtract, Toggle or Remove to the configured variable, subject to type and operation validity. Connect Next to continue.

Example: Set Dialogue.Variable.HasMetAnna to true after the introduction. This does not automatically modify a quest system outside the component.

How to use this node

1. Open a Dialogue Asset and right-click an empty section of the graph.
2. Find the node under the category given above (START is created as part of the graph).
3. Configure its fields in the Details panel and connect the flow pins shown in your editor.
4. Save the asset and inspect the validation and runtime tools.

Runtime and integration notes

The runtime meaning is documented above from the bundled node reference. The graph is compiled to runtime node data; this is not an Unreal Engine Event Graph node. For behavior spanning gameplay objects, see Gameplay events or Blueprint APIs.
