# Visual Studio/C++ & Unreal Engine Issues
### I'm Getting Compiler Errors When Run Unreal Engine for Visual Studio
If you are trying to run UE5 from Visual Studio, then close any other UE5 executable windows you have open. If Unreal is already running when you launch it from Visual Studio then it will sometimes prevent Visual Studio from being able to correctly compile your C++ files, which results in a compiler error.
To fix this close all open instances of Unreal Engine. Once you've done that everything will be fine and you should be able to run Unreal from Visual Studio.
### I'm Getting an Error with the Build.bat in the Visual Studio Output Console
This happens when certain executables are already running in the background and haven't shutdown when they're meant to. To fix this open task manager and close `HUB for UE5 runtime traces...` and close every instance of `Runtime Broker` you can find.
Once you've done this, Visual Studio will work again and you can compile code.
`Runtime Broker` controls file permissions on windows and `HUB for UE5 runtime traces...` can sometimes have a file or folder open. From what I know this is a Games Academy specific issue mostly - my guess is that it probably has something to do with the configuration of the University computers. I've not really seen this issue for people who're not using Falmouth Uni/GA computers.
### Stucture's are Unknown when Packaging
If you get an error in the packaging log that looks like this:
```log
PackagingResults: Error: FStructProperty::Serialize Loading: Property 'StructProperty /Game/Game/VisualNovel/BP_VisualNovelManager.BP_VisualNovelManager_C:VisualNovelData.VisualNovelData'. Unknown structure.
PackagingResults: Error: FStructProperty::Serialize Loading: Property 'StructProperty /Game/Game/VisualNovel/BP_VisualNovelManager.BP_VisualNovelManager_C:Dialogue'. Unknown structure.
PackagingResults: Error: FStructProperty::Serialize Loading: Property 'StructProperty /Game/Game/VisualNovel/BP_VisualNovelManager.BP_VisualNovelManager_C:ExecuteUbergraph_BP_VisualNovelManager:CallFunc_Array_Get_Item'. Unknown structure.
PackagingResults: Error: Unknown Cook Failure
```
The the way to fix this is to rename the blueprint structure file(s) it's complaining about. Any name will do. Save all the file(s) that need saving including levels and blueprints that you haven't changed manually.
This will force unreal to update all the references to the blueprint stucture file, and fix the issue.
# Fixing UE5 Setup
### dotnet is not recognized as an internal or external command
If you get an error similar to this one when generating visual studio project files or opening the project for the first time, it's because `.NET 6` is not installed or its environment path is not set.
To fix this locate `C:\program files\dotnet`, and delete the `dotnet` folder if it exists. If it doesn't exist, then don't do anything.
Next download the .NET 6 SDK ([.NET 6 download here](https://dotnet.microsoft.com/en-us/download/dotnet/6.0)) and install it. _(do not download `ASP.NET Core Runtime`, `.NET Desktop Runtime`, `.NET Runtime`, or any other SDK - just the plain `.NET 6` SDK that has everything included)_
This will fix the dotnet error.

# All Materials are Good
Unreal Engine 4 and Unreal Engine 5 are very similar. Most of the features are still the same and a lot of the UE4 tutorials are still relevant in UE5. You only want a UE5 tutorial if it's a new feature that was intoduced in UE5 or if it was completely reworked.
This especially true for C++ and Blueprints, almost nothing has changed between versions for programmers.
These are the main differences between UE4 and UE5:
1. The UI was updated, but a lot of stuff is still in the same place as before.
2. There was internal engine refactoring which doesn't affect you.
3. Addition of Lumen - A new lighting system.
4. Addition of Nanite - A new system for rendering high poly static meshes.
5. Addition of Enhanced Input Subsystem - This is replacing the old input system, but the old system is still available for now so you can still follow old tutorials fine.
UE4 learning materials are still relevant, and sometimes the only thing available for older subjects that haven't changed for years.
_You can also find a lot of official learning materials made by Epic Games on their community website: [https://dev.epicgames.com/community/unreal-engine/learning](https://dev.epicgames.com/community/unreal-engine/learning)_

### Version Control
Be careful when working on files in Unreal Engine. `.ini` config files and code files can have their changes merged. All other files in Unreal, typically with the file extentsion `.umap` or `.uasset`, cannot be merged like text files can be. These are binary files, so you can't merge the work from 2 different people on the same file. To my knowlegde almost everything you create inside the Unreal Engine Editor will be a binary file, so be careful.
Your teams need to maintain good communication to ensure you don't loose work from two people working on the same asset at the same time, and then having to trash someones work because of the merge conflict.

# Getting Started with Unreal C++
### C++ Programming Course - Beginner to Advanced
[C++ Programming Course - Beginner to Advanced](https://www.youtube.com/watch?v=8jLOx1hD3_o) - This is a 31 hour video going over all the programming and C++ concepts. Use the `MSVC` compiler, don't use the other options they show like `Mingw` or `Clang LLVM`.
### Unreal Engine Modules
If you want to use C++ in your projects you will need to be familiar with adding modules to your project. Unfortunately this isn't taught very well despite how simple it is. Not knowing how to add modules will cause linker errors at compile-time preventing the project from compiling.
I can't find any simple learning materials. For anyone getting started learning Unreal C++ reach out to me _(`rr262471`/`Rian Rutherford`)_ while I'm at the GA and I might be able to give you a quick 5 minute crash course while I'm there if I have the time.
1. [Build.cs & Target.cs](https://unrealcommunity.wiki/build.cs-hv582z08)
2. [Improving Code Structure with Unreal Engine's C++ Modules](https://dev.epicgames.com/community/learning/tutorials/xJ/improving-code-structure-with-unreal-engine-s-c-modules) - This goes way too indepth and you don't need to know 90% of the content in the video, but it's a good watch if you want to learn how to make you own Unreal Engine modules and what they are.
### Opening The Project: For Programmers
If you're a programmer and plan on doing work in C++ you should right click the `<yourgame>.uproject` file and select the `Generate Visual Studio project files` option. When this is complete double click the `<yourgame>.sln` file and run the game from Visual Studio by clicking `Local Windows Debugger`. Whenever you code in C++ you should close UE5 and recompile it from VS.
If you are not doing anything in C++, then you can open the project straight from double clicking `<yourgame>.uproject`. Make sure you click yes on the prompt asking to compile. UE5 will take awhile to open because it's compiling C++ binaries in the background.
If UE5 is being weird, delete all the cache files/folders & generated files/folders, then reopen the project from Visual Studio so it's forced to compile everything correctly and you will catch any compiler errors if anything is wrong.
### I don't know how to setup VS2022 for Unreal Engine 5
Follow this guide: [Setting Up Visual Studio Environment for C++](https://docs.unrealengine.com/5.1/en-US/setting-up-visual-studio-development-environment-for-cplusplus-projects-in-unreal-engine/)
### Garbage Collection
[Garbage Collection](https://unrealcommunity.wiki/garbage-collection-36d1da) When using pointers on class member variables, that contains a type inheriting from `UObject`, you need to have a `UPROPERTY` macro attached to the variable. This is because `UPROPERTY` helps with tracking memory for the garbage collector.
# Multiplayer in Unreal
_Note - You can do multiplayer programming in Blueprints or C++. For basic applications Blueprints are fine, but they do have limitations because they don't have access to everything multiplayer like C++ does._

# Introduction
This is the **ROOT** folder for the unreal game project.
_NOTE - Unreal has blur enabled by default, disable this in project settings if you don't want blur._
# Adding UE5 Game Project
1. Open unreal, select a template, and create the project template anywhere.
2. Open the **ROOT** folder of the UE5 project you just created and copy `yourgame.uproject`, `Content`, `Config`, and `Source` into this folder.
3. If your `yourgame.uproject` file and `Content`, `Config`, `Source` folders are in the same directory as the repositories `.gitignore` file, then your setup is correct.
Once you've completed the above steps you're ready to open the project and start working.
# Opening The Project: For Programmers
If you're a programmer and plan on doing work in C++ you should right click the `yourgame.uproject` file and select the `Generate Visual Studio project files` option. When this is complete double click the `yourgame.sln` file and run the game from Visual Studio by clicking `Local Windows Debugger`. Whenever you code in C++ you should close UE5 and recompile it from VS.
If you are not doing anything in C++, then you can open the project straight from double clicking `yourgame.uproject`. Make sure you click yes on the prompt asking to compile. UE5 will take awhile to open because it's compiling C++ binaries in the background.
If UE5 is bing weird delete all the cache files/folders & generated files/folders, then lauch it from Visual Studio so it's forced to compile everything correctly and you will catch any compile-time bugs if anything is wrong.

# Introduction
This is a Unreal Engine template for 5.1 or greater.
The template was made by **Rian Rutherford** _(rr262471)_. To make the template, I used the pervious UE4 template as a starting point.
`Documentation` is an optional folder, it can be deleted if you don't want it.
If you want, you can rename the `Game` folder to something else. What is important is to make sure whatever the folder name, it has the original `.gitignore` and `.gitattributes` file inside.
If you are using Unreal Engine for the first time, or a first time UE5 C++ programmer, you need to read the [Project Root Readme](Game/readme.md). It has information for setting up your Unreal Engine 5 project with the template, and opening the project as a programmer for coding in C++.

# WARNING!!!
Do not put in development or completed project assets in this repository. When you import assets into unreal they're taken into unreal and changed into `.uasset` files. Because of this it's wasteful to put the original development assets in the game repository. Doing so bloats the project and increases cloning times of the project for everyone.
Instead you should have another repo that uses the [art-lfs-repo](https://github.falmouth.ac.uk/Games-Academy/art-lfs-repo) template. This is where you put your development assets like your models and textures while working on them, including your completed ones. Then when you're done, you import them into Unreal Engine (and UE5 will store the files internally in its own format).
