Behaviour Tree task node, the function node “Set Blackboard Value as Vector” fail. Vector KeyValue in blackboard invalid
I wanna try use the “Behaviour Tree” to get my enemy action in heself as the UE4 document. But I got some problem.
I have done all things in the document Behavior Tree Quick Start Guide | Unreal Engine Documentation
It is step 5, the task is to find a potrol location to move.
I run the BT finally but the actor didn’t walk to the target location.
As I see, the “PotrolLocation” is invalid as following picture
and the “Set Blackboard Value as Vector” node in the task node worked well.
I took much time to get the way, but I failed. Can someone tell me why and help me to solve this problem. Thank you so much.
