From this description I imagine it works like this: I create an UPROPERTY with this Unreal Engine uses a hierarchical garbage collection system, meaning that there is a set of root objects and all other objects are part of an outer-chain that ends at one of the root objects. I’m checking if that class have specific variable using this approach: GetClass()->FindPropertyByName(“DialogueTree”) This is must be a variable of UBehaviorTree type. It looks like one, so the compiler accepts it, but it actually is used by the Unreal Header Tool (UHT) to create code that will then be added in the GENERATED_BODY BenUI has compiled an exhaustive list of all available core and metadata UPROPERTY Specifiers available within Unreal Engine.
