Thanks a lot man - unfortunately I still can’t open the project, and it might be because I’m not updated to the latest update of Unreal (I’m on 4.13.1), which I’m afraid to do until I hand this project in as my dissertation in a couple of weeks.
Because of this, I’m not entirely sure how to make each of the things on the BT you’ve shown me, such as the BTService_GetTargetData. I’m going to try and play around with it but any help on the specifics of these would be brilliant!
Sorry for the hassle!
