Transform BBParameter not "sticking"

[aer0ace]

I have the following action attached to the first state:

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 26 27 28 29 30 31

using NodeCanvas.Framework; using ParadoxNotion.Design; using UnityEngine;   namespace Tasks.Actions {       [Category("Units")]     public class FindChildTransformWithName : ActionTask     {           [RequiredField]         public BBParameter<string> gameObjectName;         [BlackboardOnly]         public BBParameter<Transform> saveAs;           protected override string info         {             get { return "Find Transform " + gameObjectName + " as " + saveAs; }         }           protected override void OnExecute()         {               GameObject obj = GameObject.Find(gameObjectName.value);             saveAs = obj.transform;               EndAction();         }     } }

and in the subsequent action, I try to use the transform that was saved to the blackboard in another custom action:

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 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55

using NodeCanvas.Framework; using ParadoxNotion.Design; using UnityEngine;   namespace Game.Tasks.Actions {       [Category("Units")]     public class RotateTransform : ActionTask     {           [RequiredField]         public BBParameter<float> increment;         [BlackboardOnly]         public BBParameter<Transform> transform;           protected override string info         {             get { return "Rotate Transform " + transform + " by " + increment; }         }           protected override void OnUpdate()         {             base.OnUpdate();               if (transform == null || transform.value == null)                 return;               float dt = Time.deltaTime;               Transform t = transform.value;               t.Rotate(new Vector3(0.0f, increment.value, 0.0f));               transform = t;           }           protected override void OnExecute()         {             if (transform == null || transform.value == null)                 return;               float dt = Time.deltaTime;               Transform t = transform.value;               t.Rotate(new Vector3(0.0f, increment.value, 0.0f));               transform = t;               //EndAction();         }     } }

But when this action executes, the blackboard variable that saves the transform is null….

Is this expected? How do I properly use this?

All right, as usual, I fix my problem a few minutes after posting a question…

Instead of
saveAs = obj.transform;
it’s (and I swear I tried this first, and it didn’t work):
saveAs.value = obj.transform;

Glad you found the solution and for letting me know.
Yes, you should always use the .value property of the parameter instead of the parameter itself 🙂
