Ok, so I have followed this whole tutorial https://docs.unrealengine.com/latest/INT/Engine/AI/BehaviorTrees/QuickStart/index.html and have triple checked all my blueprints for an error. this is my problem
as you can see in the right corner there is no default settings. Can someone help me please?
Check your Service “AgroCheck” if you followed the tutorial it should be setup like this:

Might want to go over the tutorial again and double check that everything is correct.

Ok, so I have check all of them and I have not found any errors but this one
On the use blackboard it says I need a blackboard component, but he doesn’t. Also I have looked and that is the only use blackboard component.
What does your AgroCheck service look like? That is where the values get updated to the blackboard, that is where I see it in the tutorial from the link I posted above.
I have and again there are no errors except again that other one. If you want you can go ahead and check yourself, but i’m sure there are no errors.
Set your TtargetToFollow and TargetLocation to editable and try it again.
Thanks for pointing that out but sadly, it still wont work.
oh sry it does i just had to refresh it thanks.
