[Major Bug] Standalone Action Player Actions lose reference to Blackboard

[erikParticipant]

Looks like the StandaloneActionPlayers ActionTasks loses all references to their Blackboard.

When launching the game, creating a prefab, and every other action that serializes them.

That component is a real time saver for me.

I have hotfixed this for me by changing in ActionListPlayer.cs

1 2 3 4 5

void ISerializationCallbackReceiver.OnAfterDeserialize() {             _actionList = JSONSerializer.Deserialize<ActionList>(_serializedList, _objectReferences);             if ( _actionList == null ) _actionList = (ActionList)Task.Create(typeof(ActionList), this);         }

to

1 2 3 4 5 6 7 8 9 10

void ISerializationCallbackReceiver.OnAfterDeserialize() {             _actionList = JSONSerializer.Deserialize<ActionList>(_serializedList, _objectReferences);             if ( _actionList == null ) _actionList = (ActionList)Task.Create(typeof(ActionList), this);               foreach (var a in _actionList.actions)             {                 BBParameter.SetBBFields(a, this.blackboard);             }         }

But this spawns an Exception, a more robust solution would be greatly appreciated.

1 2	UnityException: get_isPlaying is not allowed to be called during serialization, call it from Awake or Start instead. Called from MonoBehaviour 'ActionListPlayer' on game object 'GameObject'. See "Script Serialization" page in the Unity Manual for further details.

Thnx. 🙂

 

Cheers

Hello,
Thanks for the report. To fix this, please keep the OnAfterSerialization method as it originally was and instead change the method UpdateTaskOwner to be like this:

1 2 3 4 5 6 7 8 9

public void UpdateTasksOwner() {             actionList.SetOwnerSystem(this);             foreach ( var a in actionList.actions ) {                 a.SetOwnerSystem(this);                 BBParameter.SetBBFields(a, blackboard);             }         }

Let me know if that works for you.
Thanks 🙂

Yes, that works. Thanks for the fast reply. 🙂
