Data flow

Arbor has a function to pass data between nodes of the graph.

Data flow

Connecting data input / output slots allows you to take advantage of data flow.

Example

In the example using the built-in script, the following data flow can be easily assembled.

  1. InstantiateGameObject instantiated prefab.
  2. Output instantiated GameObject.
  3. Get the Rigidbody component with Rigidbody.Get.
  4. Add force with AddForceRigidbody to the received Rigidbody.

Data flow can be used in BehaviourTree as well.
