Unreal Engine Blueprint Function Library (Patreon)

Unreal Engine Blueprint Function Library, or BFL, is a set of UClasses mostly comprised of static functions that provide utility functionality that is not bound to any particular gameplay object. In this tutorial we present a simple introduction to BFL and how we can use them to exponentially improve our reverse engineering experience.

🎮 Unreal Engine's Blueprint Function Library

📚 Static UClasses offering object-agnostic utility

🔬 Example: GameplayStatics

🌐 Find actors, spawn objects & prediction

🔧 Dump BFL classes with GH UE Dumper

🚀 Leverage static UFunctions in BFL for game mods

Blueprint Function Library Examples​

There are a lot of BFL classes in the unreal engine by default. Developers may add their own classes for specific purposes, but regardless the classes that come with the engine itself are pretty powerful and cover the majority of the tools required for hacking/modding purposes. An example is the GameplayStatics class, which contains methods which can locate actors, damage actors, spawn objects, and even predict projectile paths.
