How to run a FlowGraph from C# and get the value from ControlOutput

Hello everyone,

I'm trying to create Abilities defined by Scriptable Objects (SO) using Bolt's FlowGraph to make it easier for designers.
but I couldn't figure out how to execute FlowGraphs and get the generated SOs via C# scripts.

Thanks!

 

Hi!

Did you find any solution?

 

I created a method that is quite crude in its implementation and was wondering if there is a more elegant solution available.

Code (CSharp):

1.  
2. public static class ScriptGraphAssetExtensions
3. {
4.     public static T Run<T>(this Unity.VisualScripting.ScriptGraphAsset graph, string method, object arg, string outputVariable) where T : class
5.     {
6. #if UNITY_EDITOR
7.        if (!Application.isPlaying)
8.        {
9.            return default(T);
10.        }
11. #endif
12.        var go = new GameObject("Temp");
13. #if VISUALSCRIPTING_1_7_1_OR_GREATER
14.        go.AddComponent<Unity.VisualScripting.ScriptMachine>().nest.SwitchToMacro(graph);
15. #else
16.        go.AddComponent<Unity.VisualScripting.FlowMachine>().nest.SwitchToMacro(graph);
17. #endif
18.        Unity.VisualScripting.CustomEvent.Trigger(go, method, arg);
19.        var variables = Unity.VisualScripting.Variables.Object(go);
20.        object output = default(T);
21.        if (variables.IsDefined(outputVariable))
22.        {
23.            output = variables.Get(outputVariable);
24.        }
25.        GameObject.Destroy(go);
26.        return output as T;
27.     }
28. }
29.
