Mono C# Bindings for Unreal 4

[anonymous_user_2253ece8]

@Martin Bean;15413

Why attach it to a game? What if a team of dev’s(not tied to a studio/game/project) wants to make C# bindings for UE4 available for everyone?

Hi, Martin,

Not really, it does not need to be a game, it can be anything using UE.

Thanks,

You have no idea how slow mono is compared to microsoft .net espacilly in cases that matter for us, like large collections and processing these.

I would be happy to see C# in UE4… but i doubt anyone is going trough all this for free. Important is that performance stays the same or better sayed no one should see in the first look this is done via C# because its feels slow.

PS: C# Dev’s will learn C++/11 before a proper Plug-In for UE4 come out

I really hope this doesn’t bleed back to the Epic branch

I really hope it does!

[anonymous_user_537a337d]

If it did support Mono then some of our previous work would carry over. However, we made heavy use of ScriptableObjects and not sure how that would play out. Anyway, we moved to SO’s because we couldn’t use normal class inheritance, instantiation, or something similar. Can’t remember the details now. . .but it was a major annoyance.

Sure use C#, provided it’s officially supported by Microsoft, which I state for two important reasons: the engine needs to be developed and maintained by talented people; and people maintaining it need to get paid. Otherwise you get Mono, with Xamarin.

It is my opinion, and I can be wrong about this, Epic can afford to release the UE software due to other revenue streams. One of two things could be happening: Epic is dumping the code because internally they have something much better they are about to turn to, or, they’ve become so successful with their tool that there’s really little harm in sharing it with others. And it’s an added bonus to have additional eyes reviewing what’s been done, and improving upon it.

Again, outside the hobbyist, it’s very tough making a living with tools that aren’t mainstream, updated regularly with the latest technologies. With real-time ray tracing quickly approaching I have more confidence in professional teams (academia, and commercial) than the hobbyist teams. 2 cents.

Mono binding and licensing

We are very happy to see the growing excitement of using C# with Unreal Engine. Like said, it can be a little cumbersome to embed Mono on a C++ engine, and also note you will need a commercial license to the Mono runtime to redistribute Mono in most-non trivial uses in a game.

In particular, you will need a commercial license for distributions on any DRM-powered platforms or Application Stores, since it is not possible to both comply with the terms on the stores/DRM systems and the requirements of the GNU LGPL.

It also conflicts with the Unreal EULA: Game-Engine-Technologie von Unreal - Unreal Engine

The good news is that we are happy to work with interested parties, both in regards to the technical challenges of embedding Mono, as well as for obtaining a commercial license. For more information, feel free to contact me at

Hi, everyone on this thread,

I am the founder of xInterop Software and the author of xInterop NGen++, a C# wrapper generator C++ DLL at http://www.xinterop.com, you may want to take a look at how it can do for you.

We would like to give out 5 copy of xInterop NGen++ Standard version with distribution licenses for free. What we expect from you is a free DEMO copy of your final game software for us to demonstrate how you use xInterop NGen++, that is all.

If you are interested in using C# with Unreal, and would like to write C# on top of Unreal C++, Please contact me for the free license. You can also express your interest in this thread.

Thanks,

hey , can i get a license ? I am using ue 4.4 right now to make a game, and i am actually a c# unity developer. So may i know the steps on getting the license ?

[anonymous_user_a743a820]

Where is this at right now for development?

[anonymous_user_15bfc3a1]

Yes. I would also like an update, if there is one.

How to C# in UE4

Expect it in November according to the following comment on the video -

“we are still working on this and we believe to have it accessible to the public in November.” - Christian Lönnholm

Are there any plans for releasing a guide/tutorial for migrating Unity C# projects over to UE4, it seems there will be a growing demand for this as Unity developers switch to Unreal (myself being one of them).

No matter how good they make the code editor in UnrealEd, they need to have it integrate into Visual Studio or MonoDevelop in the same way Unity does. Being able to add references to .NET/Mono libraries and even NuGet packages would also be valuable.

I’m not against C# at all, I’m being realistic. If you wanted a slow engine why aren’t you using Unity? Anything larger than a non trivial project in Unity runs into memory issues.
Do you know anything about VM’s?

Unity’s memory issues are a result of an archaic mono GC. You cannot necessarily point to Unity’s performance with GC and generalize it to all of .Net and mono applications.

What is the Status of the UE4 / C# Product

It is now December… What is the current status… Where can it be download/purchased from?

@;12237

We are currently looking at releasing v1 of our C# implementation by June. We are also planning on an evaluation, indie, and pro build of the plugin.

Great to hear how ambitious the community is with embedding mono. One word of caution is on the GC side of things. You’ll want to use SGEN for an embedded Mono implementation. Otherwise you’ll start running into memory thunking issues pretty quickly. Embedding Mono is no small task in UE4 and requires some serious thought as to what the outcome should be for UE4 developers. Are you looking calling the engine or calling the C# DLL? What about integration with BluePrints?

Also another word of caution. Our solution takes advantage of the existing macros in the engine used for declaring BluePrint exposure such as UFUCTION() UCLASS() UPROPERTY() macros decorated across the codebase using a clever little macro setup that is engaged by the UBT.

================

Right now we have a C# based UE4.DLL which can be included in any standard C# compiler as well as used by our own compiler built directly into the UE4 Editor. On the C++ side we have a MonoRuntime and Script Engine Plugin for Engine as well as a Script Editor Plugin for Editor.

The UE4 C# library currently as it stands binds to the entire Game Framework sanely as well as any inherited classes that the Game Framework uses. So this includes common game logic UClasses like Actor, PlayerController, and Pawn (just to name a few). We have also binded Core and several other necessary parts of the engine.

You will have a few setup steps in C++ before you can begin using the Plugins with your game. You’ll need to setup the Plugin in your Game DLL. We are working on ways to overcome this step to make this feel as natural as possible to C# developers.

We also provide a Script Editor which lives inside of the UE4 Editor which allows developers to write and compile C# directly in UE4! We use the mcs to compile C# scripts into DLLs which are placed alongside the C++ Binaries.

We are shooting for the most natural Unreal Coding experience possible in C#.

So can we use Mono Unreal Engine in our game or not?

So can we use mono or not?

The Mono Unreal Engine web site ships source code to mod the engine (4.4) using mono. If we cant use mono, why is there even an mono unreal engine project that says if you want to distribute your game, you need to the Xamarin Commercial Products:
Xamarin.Ios
Xamarin.Mac
Xamarin.Android

Business Editions (Especially to use mtouch from command line… also has details in the license.rtf about what libraries you can link with like libmonosgen) and what edition you need… Stater sucks… bite the bullet and get the Business Editions

I have all three Xamarin Business Commercial Products (Will costs a small fortune… just kidding, although not that cheap 1000 bucks for each platform each year for the subscription, but i am a .NET Enterprise Application developer by trade… i need those tool to make enterprise apps… gotta make money somehow)… So Xamarin Studio and Xamarin API’s have been a part of my personal Development Toolchain for years.

So to be able to use that (and all my PCL async httpclient client to easily talk to my game server ASP.NET hosting application i have developed for my game would be awesome!!!)

A Definite YES or NO would be appreciated before i spend months or years developing my game code in .net and can never ship

Hey everyone,

So yesterday I asked the head guy over at much different how long it will be til we get C# in unreal 4.

His reply: “Super Soon”

https://plus.google.com/u/0/112331437607481686388/posts

My guess is we get some sort of official announcement at GDC.

[anonymous_user_6f48ddab]

It’s exciting to see this happening but I still question mono being the best candidate for the binding considering all of the changes Microsoft has put in motion with the official .NET framework. The licensing issues of the past with .NET are no more

I might be mistaken but you are not able to deploy to Android and iOS with .net 2015.

If some one could enlighten me please do

Having a wrapper like this would make my “job” (hobby) so much freaking easier, especially seeing how I will be attempting to integrate speech recognition into the engine. I’ll check out the link (I don’t want one of the free copies, since I do not know if I’ll be going into production, and would like a production-ready dev to get a copy).
