[NC2] Cannot assign to BBParameter from a dynamically typed node.

[M4rc]

I’ve made a similar node to SetOrtherBlackboardVariable.cs using the following pattern, with Person being a custom class of ours:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

public BBParameter<Person> TargetPerson; public BBParameter<string> TargetVariableName; public BBParameter NewValue;   protected override void OnExecute() {     if (TargetPerson.value != null)     {         TargetPerson.value.LocalBlackboard.SetValue(TargetVariableName.value, NewValue.value);     } }   //////////////////////////////////////// ///////////GUI AND EDITOR STUFF///////// //////////////////////////////////////// #if UNITY_EDITOR          protected override void OnTaskInspectorGUI(){     DrawDefaultInspector();     if (GUILayout.Button("Select Type"))         EditorUtils.ShowPreferedTypesSelectionMenu(typeof(object), (t)=> {NewValue = BBParameter.CreateInstance(t, blackboard);} ); } #endif

However, when I assign a blackboard variable of type “Person” to NewValue, and that variable is set to a valid value, then trigger my node, then NewValue.value is null. The TargetVariableName is correct. I can’t seem to figure out what I’m doing wrong in this case, is there anything you can think of?

Thanks in advance,
Marc

Hello,

May I suggest you to use a generic task instead? It’s more..”bullet proof” :). Here is an action:

1 2 3 4 5 6 7 8 9 10 11 12

public class SetPersonVariable<T> : ActionTask<Person>{   public BBParameter<string> TargetVariableName; public BBParameter<T> NewValue;   protected override void OnExecute(){ agent.LocalBlackboard.SetValue(TargetVariableName.value, NewValue.value); EndAction(); } }

The SetOtherBlackboardVariable will even change to use generics as well.

Let me know if that solves the issue.
Thanks.

Thanks, that worked! And is a more generic solution.

Cheers,
