Local Blackboard is not being used. Fix included ?

[erwan]

Hi everyone,
I am in the specific case where I want my behaviour tree to use the local black board (I am not using any component)
And the problem is that when the code says : “let’s use the local black board !” et actually sets it to null one line later.

In Graph.cs :

1 2 3 4 5 6 7 8 9 10 11 12 13 14

623  if (blackboard == null){ 624    if (agent != null){ 625      Logger.Log("Graph started without blackboard. Looking for blackboard on agent '" + agent.gameObject + "'...", "NodeCanvas", this); 626      blackboard = agent.GetComponent(typeof(IBlackboard)) as IBlackboard; 627    } 628    if (blackboard == null){ 629      Logger.LogWarning("Started with null Blackboard. Using Local Blackboard instead.", "NodeCanvas", this); 630      _blackboard = localBlackboard; //  "let's use the local black board !" 631    } 632  } 633 634  UpdateReferences(agent, blackboard); // Actually no, set the black board to null

Shouldn’t the line 630 read :

1 2 3

630      blackboard = localBlackboard; ?

Overwise the blackboard is set to null again because of the call to “UpdateReferences(…)”

Merci !

Hello,

Yes, you are right 🙂 This is a bug introduced from a refactoring, and the fix is exactly what you suggest here:
blackboard = localBlackboard;

Thank you for letting me know!

You are welcome,
It’s good to know I’ll be able to discard the fix on the next update.
And bravo to open source code !
