Error: Accessed none from node Set Value as Bool ...
Hey, I get error Accessed None 'CallFunc_getBlackboard_ReturnValue' from node Set Value as Bool in graph 'EventGraph' in blueprint PCSCharacter
I was following tutorial: https://www.youtube.com/watch?v=MILsSv_fPPQ
I know it is older version, but so far it proved to be what i was looking for.
Problem is somewhere near changing boolean attribute called IsChasing. This attribute is defined in blackboard and i needed to change it to true in my NPC character (blueprint class). But I think you cant access it by tag like Set(attribute) to true because it is defined in that blackboard (probably).
So by following tutorial i get this:
Variable in make literal name is called precisely like the refered to one.
When i create 1 NPC no problem occures, but when i create 7 NPC behavior tree start to act funny and switch without triggering NPC by box.
When i debugged i was that boolean variable IsChasing is changing on its own, sometimes(with multiple npc)... I am sure i am not in any of triggering boxes, I have them visible.. Any idea how to fix this?
behavior tree: Thx for help

I am not sure I entirely follow what you're doing. If you want more specific help, it may be a good idea to upload entire blueprint for us to have a look at.
A couple of things that jump out at me:
Try those two things and let us know how you went
For anyone having this Error "Accessed None 'CallFunc_getBlackboard_ReturnValue' from node Set Value as Bool in graph 'EventGraph' in blueprint PCSCharacter" The FIX is the Box you made can not be inside the NPC so move it out side of it. This is what fixed my problem.
