Ue4 Visual Studio Code

Posted on  by



Slow pop-up for suggestions working on C code with Unreal Engine Visual Studio 19 Hi all, so I try to learn Unreal Engine while using C (basically learning both engine and C at the same time), and I managed to install Visual Studio with all the plugins required for use with Unreal Engine, as well as followed setup guide for Visual Studio. Visual Studio is an essential package for code editing when editing the C code for your UE4 game.

Visual Studio Code not working with UE 0 I have started using Unreal Engine and wanted to switch from VS 2017 to VSC because intellisense in VS is not very good and often simply stop working.

Ue4 Visual Studio Code

Welcome

This is a series about Unreal Engine 4 Multiplayer Deathmatch. In this series we go through Setting up of Dedicated Server using Source code and creating a Deathmatch multiplayer Game Mode.

Unreal Engine 4 versions this tutorial supports

  • 4.23
  • 4.24
  • 4.25
  • 4.26

In order to build Dedicated Server you need source code of UE4. Source code takes around 100gb hard drive space.

Visual Studio

Before we can build UE4 Source code we need to install Visual Studio.

You can use Visual Studio 2017 or 2019 to build Source code. For 4.25 or later it’s recommended to use Visual Studio 2019.

Ue4

Once you have installed Visual Studio, UE4 requires some special libraries. You can install those using Visual Studio Installer.

Windows key -> Visual Studio Installer -> Modify

Install Unreal Engine installer.

For Visual Studio 2019 select Universal Windows Platform development, .NET desktop development and Desktop development with C++

Files

Before we can do anything we need to get the source code and build it.

Download Unreal Source Code from GitHub.

Login to Github and click Join to see this page:

Open up command prompt as administrator.

Type “pushd” and location where you unzipped the file.

Type “Setup.bat”

When it has finished that

Type “GenerateProjectFiles.bat -2017” or -2019 depending on your visual studio version.

Go to folder and launch the solution “UE4.sln”

Set build configuration to “Development Editor”

Then in Solution Explorer right click UE4 and select Build

After it has finished, right click UE4 again and select “Set as Startup Project”

Then launch it from “Local Windows Debugger”

Believe it or not, that’s it. Once it has finished Building Shaders create a ThirdPerson Blueprint Project and you’re good to go.

I prefer Blueprint because you get the Character stuff all in blueprint and that’s what we are going to work with.

Server Setup

Set up Maps

Create “Maps” folder and add two empty levels “entryLevel” and “transitionLevel”.

And your game level map as “MainLevel” or any other name.

Then Build Maps so we can get “Map Build Data Registry”.

Unreal visual studio setup

Go to project settings -> Maps & Modes.

Open Default Maps from a small triangle pointing down.

And set all maps like in picture below:

Add Open Level node in entryLevel Level:

Now cook Content:

Building Client

Once you have finished cooking the content you can build Client.

Building Server

It’s not possible to build a server with Visual Studio. So we have to build it with Unreal tools.

Create a new file ProjectNameServer.Target.cs

Replace “DebServerTut” with your project name.

Then add it in Sources folder:

Set Build Target to Server:

Now you should be able to build it:

You can also build it using UnrealFrontEnd:

You can launch UnrealFrontend from Right click -> Debug -> Start new instance.

Set uproject file first:

Then set it like this and hit Launch:

Launching Server and Client

Once you have build both Server and Client go to WindowsServer folder and create shortcut to Server executable.

In server.exe shortcut add “-log” at the end of target:

WindowsNoEditor is the client folder and it should look like this:

Launch server first from shortcut and then client.

Building for Linux

Building Linux is very simple once you get Cross platform toolchain.

So just install this and then Package Project -> Linux

Problems & Tips

4.23

Visual Studio Code For Ue4

Can only be built on Visual Studio 2017 and older because of mathtest failure.

PsAllocator

If you get this problem:

C1083 Cannot open include file: 'typeinfo.h': No such file or directory

Go to Solution Explorer, type in search bar “PsAllocator.h”

In “PsAllocator.h” file go to line 43 and make sure that it’s

  • “typeinfo”
  • and not
  • “typeinfo.h”

Megascan

If you add Megascan plugin with Bridge (into Source code Plugins folder) you need to close unreal editor and visual studio and then start the solution again (UE4.sln), then launch the solution (local windows debugger) so visual studio can update the project. Otherwise you’ll get this error: Plugin ‘MegascanPlugin’ failed to load because module ‘MegascanPlugin’ could not be loaded.

No C++ Code

If your File Menu looks like this, you need to add New C++ Class in order to be able to build a Server.

Good to Know

  • Your Source Code build is unique, this means that if you build plugins with it they don’t work with Epic’s Official Unreal Engine 4 release build. You need to compile the plugin with the official build.
  • You can simulate the server environment in the editor. So you don’t need to build a server unless you want to see how it performs as a standalone.

There are few IDE (Integrated Development Environment) supported by Unreal Engine.

Grab Preview from [https://www.jetbrains.com/lp/rider-unreal](). Yes, this is a Preview, but already beat Visual Studio or Visual Studio Code in almost everything.

Rider is a new option for C++ in general and Unreal Engine from JetBrains. This company is well-known for providing excellent tools for programmers, especially multiple IDEs specialized in specific languages and industries. For example, CLion is a standard JetBrains for C++, but they work towards making Rider (traditionally a C# IDE) the 'gamedev IDE'. Rider already provides excellent support for C# and Unity, with a customized UI and debugger. And Resharper C++ provides support for C++ and Unreal Engine as the extension to the Visual Studio.

Pros

  • Nearly as lightweight and responsive as Visual Studio Code, despite providing much more features. It's extremely pleasant to jump from the Visual Studio which often runs very slow, hangs for many seconds during editing or using a debugger.

  • UI is modern, clean, very customizable. It's so much easier to find information, read debugger values.

  • Resharper is built-in, providing almost every feature from Resharper C++ (Visual Studio plugin). This gives us advanced (and fast!) code search, navigation, refactoring actions and code inspection! That's priceless while working with such a huge codebase as the Unreal Engine.

  • Resharper simplifies maintaining the coding standard and a healthy codebase in the entire team.

    • It thanks to auto-formatting and code inspection that works great, and you can tweak every single detail.

    • You can extract such settings as Code Style and Code Inspection to the team-shared settings saved to the repository.

  • Rider for Unreal Engine adds some voodoo magic. It's able to analyze assets in the Unreal project, so it can do things like. No other IDE does that, there are no such Unreal-specific features in VS or VSC

    • Displays blueprint classes inheriting after viewed C++ header. It creates links to these blueprints allowing to open blueprint editor with a single click.

    • Displays default values overridden by blueprints and .ini files! The editor also creates links to assets, i.e. material assigned to the property.

    • Find usages of C++ function in blueprints.

    • It can create property or class redirect in .ini if you rename property or class exposed to blueprints.

  • It supports all Version Control Systems out-of-the-box, including Perforce.

  • The final, production-ready version will be available on Windows, Mac, Linux. Supporting both C# with Unity and Unreal with C++ in one IDE.

Cons

  • It's only free during the Preview phase. The free license is valid till May 2021, although it may be prolonged (already have). Later on, you need to pay for it. See Pricing options. That's no issue for professional programmers, but might a barrier for enthusiasts.

  • It's not a default IDE in Unreal Engine. We might expect excellent support from JetBrains, but most probably Epic gonna stick with a free and proven Visual Studio as the default IDE. At least, for some time.

What's missing in Preview?

  • At this point, it only works on Windows with MSVC compiler. For this reason, working with Rider still requires intermediate Visual Studio project files, although Resharper uses its own project model for Unreal Engine (starting from UE 4.24).

  • Mac version is coming soon, they're just started work on the Linux version.

  • JetBrains team needed to write their own C++ debugger, as VS debugger is an integral part of the VIsual Studio. It might lack some functionalities or have bugs, although basically, it runs great!

  • It doesn't yet support debugging consoles.

  • It doesn't yet provide an equivalent to UnrealVS extension. You can still set command line parameters for the Unreal Engine process, but it's not convenient.

  • The official status report: Any ETA on production-ready Rider for Unreal Engine?

You can grab Visual Studio Community for free!

Pros

  • It's a proven and well-known editor for gamedev programmers. It should your default choice if you wouldn't use Rider for any reason.

  • C++ debugger is excellent, as is developed by the same company that develops Microsoft Visual C++ compiler.

  • For these reasons, it's the default IDE for Unreal Engine. Used by Epic Games for a very long time, so they provided these resources:

    • Setting Up Visual Studio for Unreal Engine - official guide installation and basic setup

    • UnrealVS Extension - it's a very useful extension, lets you easily add launch parameters and build many configurations at once

Unreal Engine 4 Visual Studio Code Setup

Cons

  • It's surprising, but VS support for editing C++ is... almost non-existent. There's Intellisense, but it doesn't work properly with huge codebases like the game engine. Many programmers simply prefer to disable Intellisense. There are also not many features for code search, navigating, refactoring.

  • Vanilla Visual Studio doesn't provide any Unreal-specific support.

  • Perforce plug-in isn't part of the Visual Studio itself. You need to add P4VS plug-in yourself, but it's free. This plug-in automatically checks out (marked as edited) every source file you're starting to edit. This way working with Perforce is convenient for programmers.

  • It's based on the old architecture and supporting so many languages, so it can't be easily reworked by Microsoft. It's still a 32-bit process that may use only somewhat above 2GB RAM. That's for IDE, all the plugins, loaded project data. Resharper C++ itself needs hundreds of MBs. That's the main reason why VS is so sluggish when used for big projects. And every Unreal Engine project is considered big since it includes engine source code.

  • The free Community Edition is only applicable for students, open-source and commercial studios with 5 or fewer concurrent (VS) developers. The bigger company should use a paid Visual Studio edition.

Fixing VS usability

Unreal Engine 4 codebase contains a few millions of lines of code. It's too much for clean Visual Studio to handle such an enormous codebase, so nearly every programmer needs a supporting plugin. And these also come with many editing features and Unreal-specific support.

You can choose one of these two described below. Both are paid, but definitely worth it.

  • Resharper C++ - yep, that's a JetBrains plugin described in the Rider section. Provides more features than Visual Assist, especially when it comes to code navigation and refactoring. It's also part of Rider, so it's super easy to switch between VS + Resharper and Rider.

  • Visual Assist (also know as VAX). It was the only choice for programmers for a long time. Not only for Unreal Engine programmers but also for devs working on in-house engines. VAX includes exclusive features for working with Unreal Engine.

    • Simply learn these top features. These few shortcuts are priceless time-savers.

  • UE4 Smarter Macro Indenting properly handles the indentation of the next line after UE4 macros. Thanks to this your code will look closer to the engine's Coding Standard and gonna be a bit easier to read.

    • This might be not needed if you already using Resharper C++ or a recent version of VAX.

It's not really an IDE, it's more like a smart Notepad. Although it's quite popular among programmers for few reasons.

Pros

Unreal Engine 4 Visual Studio

  • It's totally and forever free.

  • It's built from the scratch, to be lightweight and modular. It's amazing at that. VSC code search can quickly find any string in the entire codebase of the Unreal Engine.

  • It's available on Windows, Mac, Linux.

Cons

  • Epic Games provide basic support for VSC, but it's sometimes broken with the new engine release.

  • It doesn't provide advanced editing or debugging features. And it can't because of its architecture. This is the answer of JetBrains engineer: explanation why there won't Resharper for VSC.

  • Studios often expect programmers to be familiar with proper IDE, like Visual Studio or Rider. It's because advanced features of these IDEs, VAX and Resharper helps tremendously to write better code and follow the coding standard.
