The following screenshots show code that is not functioning as I thought they would. I attempt to set a blackboard value and then try to print the value and it comes up false in both scenarios. The only way I can set blackboard values is if I set it in a task or the controller itself.
Did you call “run behavior tree” within the AI controller that you are using?
Also, I’m pretty sure you can just call get blackboard, you don’t need to call get AIController.
yes the behavior tree is running. The code I posted is from within the pawn but is triggered from a task in the BT.
Maybe you are running into the same problem as this person:
Where it is updating the blackboard, you are just printing it before it shows that it is updated.
Maybe try using a different task to print it out so that it for sure makes it through the task and updates before it prints.
I would also double-check your behavior tree as it runs and make sure that the boolean value is not getting reset somewhere else.
Otherwise, I have seen multiple issues with booleans specifically in BT but I don’t remember exactly what the issue is, so you could try an enum, int, or other value?..hope this helps.
The print was just a debug addition. The blackboard value is not being set and it’s visible in the BT as such. If it were being set, the BT would run a different composite node which is not happening.
