Hi,
I am new to the Unreal engine and I am attempting to learn more about blueprints and behavior trees by following the guide here:
https://docs.unrealengine.com/latest/INT/Engine/AI/BehaviorTrees/QuickStart/index.html
I’ve gotten through the entire quick start guide twice now, once after starting with a fresh project (base top down project) but I ran into the same issue both times.
Based on executing the game I see two errors in the Behavior Tree.
The first is in the Blackboard in the Lower Selector stating “value: None(fail)”
The second is in the Second Blackboard in the Sequence stating “value: (invalid)(fail)”
Reference to what the guide had me do:
https://docs.unrealengine.com/latest/INT/Engine/AI/BehaviorTrees/QuickStart/14/index.html
I honestly don’t know where this is going wrong. My best guess is that either target to follow or target location is not getting set somehow (not sure how to check this). When I run the game, the behavior tree says it is simulating but shows up with the above described errors.
I’m using UE V4.8.0.
I will post more information if asked, I currently am unsure what would help solve my issue. Thank you for your time
