So your project will have to be a mix of Blueprints, C++ and Rust, to be able to access all engine features. You miss out on lots of C++ land Unreal Engine features that simply don't port onto the Rust language at all. There have been attempts to bring Rust to some specific consoles but nothing stable exists. Because Unreal Engine targets the C++ SDKs for all consoles. You support desktops (Mac/Windows/Linux) but you can never be totally sure that it's going to work. You have to reinvent every wheel by porting the specific Unreal Engine API features you want from C++ into Rust. What are the downsides of using Rust in Unreal Engine?

In fact, it can be done quite well if you use cxx as recommended above and then look into how the three older efforts did their porting, but update your methods to use cxx instead, for extra stability. There are three examples of people who have done that: ejmahler's recent effort is the best as far as I can see, and scape's semi-recent effort goes into great detail about how Rust FFI works in UE4/Unity, and then there's the oldest and most broken example by shadowmint. It means that you have to accept/return C++ pointers, and then manually map their values onto hand-crafted Rust structs, which in turn gets very complicated and very buggy when the Unreal Engine pointers refer to complicated classes with deep inheritance. Nobody has done it yet, though.Īlternatively, you have to manually implement the FFI interop in Rust. But this would be by far the most stable and reliable option, because it automatically generates proper header files to let you interact with all the latest changes in the Unreal C++ SDK headers. You would however have to make a C++ project for Unreal Engine and then bind that C++ project to Rust. It's way better than bindgen, and creates safe interop between C++ and Rust. The best way for Rust-to-Unreal-Engine interop would be to write something using the new cxx ( thread) tool. Several people have tried using Unreal Engine's FFI to load Rust modules, and it's definitely doable.

What about writing your Unreal Engine game code in Rust? Look at this game studio who spent 75% of their game development time fixing ways that C++ allowed them to shoot themselves in the foot.

Writing your Unreal Engine code in C++ is error-prone and it's the source of most bugs and game crashes. It's pretty low-level, and statically typed. This is a completely new language which reminds me of a mix of Python and Lua. That's what I will go into more detail about soon.įuture Scripting Language (Unreal Verse): Tim Sweeney has been talking about this for almost a decade and now it's soon a reality. so files in Unreal Engine, which means that anything that can talk/emulate C/C++ will be able to talk to the engine. And everything is unreliable, since they won't compile for all platforms that Unreal can target, nor do you have any guarantees that the 'adapter' projects will live on since they're made by third parties, so you may be left in the dust with a bunch of game code that you'll have to port to another language in the future.įoreign Function Interface (FFI): You are able to load arbitrary. A few other language bindings exist, but nothing for Rust. Third Party Binding Libraries (very unreliable): There are bindings such as Unreal.js which is an interface between the C++ engine and the V8 JavaScript engine. You are writing a strange, archaic, Unreal Engine-brand of C++ which may as well be a totally different language. Everyone says the same thing about it: You are not writing modern C++. It's archaic C++, which demands that you do things using tons of special Unreal Engine-only macros and their custom non-STL objects. And there's no way to do git repositories to track/review Blueprint changes, since it's a binary format.Ĭ++: This is the intended language for the engine. But the problem is that they require around 6 blocks to do whatever 2 lines of C++ could do. They compile straight down to C++, so the performance is great (unlike what myths claim about blueprint performance). You have four (soon five) ways to make games in Unreal Engine:īlueprints: Lego blocks that let you program game logic by dragging and dropping components. Unreal Engine comes from the dark old times, before Rust existed.

It also recently changed its licensing model to allow indie developers to use it for free. It is the most powerful game engine in the world, with the best tools for game creation, the best library of assets (including full, zero-cost, royalty-free access to the mindblowingly realistic Quixel library of objects and textures), and a massive amount of high-quality tutorials both officially produced and by third party tutors.
