Installation on Ubuntu 20.04 using Visual Studio Code

1. Create a project in Unreal Engine (4.27.2 or latest version 5.0.0)

For Unreal Engine 4.27.2

  • Get into Unreal Engine folder, type in Terminal
./Engine/Binaries/Linux/UE4Editor
  • Choose Games and hit Next
  • Choose Blank template and hit Next
  • Choose C++, leave everything as default, choose a project name and hit Create Project
  • This will take a while, go grab some coffee...
  • In the Menu Bar select File, right now you could see the option Generate Visual Studio Code Project is greyed out. If you don't see this option, please open Editor Preferences in the Menu Bar. Then in tab General choose Source Code. Then in Source Code Editor choose Visual Studio Code
  • Eventually, the Visual Studio Code window will pop up. Now you can build this project using Visual Studio Code. If it doesn't, open a terminal in Unreal Engine folder and command:
./GenerateProjectFiles.sh 'path/to/your/project/<project_name>.uproject' -game -engine

It will generate project files to build. Now you can open Visual Studio Code and add Unreal Engine to the workspace.

  • Press Ctrl + Shift + B and type <project_name>Editor Linux Development Build to rebuild the project from the IDE. Don't forget the postfix Editor after the <project_name>!

For Unreal Engine 5.0.0

  • Get into Unreal Engine folder, type in Terminal
./Engine/Binaries/Linux/UnrealEditor
  • Choose Games, Blank, leave everything as default and hit Create
  • Now you can build the project with Visual Studio Code or any IDE. For example in Visual Studio Code you can press Ctrl + Shift + B and type <project_name>Editor Linux Development Build to rebuild the project from the IDE. Don't forget the postfix Editor after the <project_name>!

2. Setup the plugins

  • Create folder Plugins inside the Project folder, clone these 3 repositories
git clone [email protected]:HoangGiang93/URoboViz.git
git clone [email protected]:robcog-iai/UROSBridge.git
git clone [email protected]:robcog-iai/UUtils.git
  • Rebuild the project with the task <project_name>Editor Linux Development Build. The result should look like this
  • Press Ctrl + Shift + D and choose Launch <project_name>Editor (Development), then press F5. This whole compiling would take about 5 minutes
  • In the end, the project will be compiled with plugins available. You can search for Robo Manager in Tab Place Actors. If it does exist, the installation is finished successfully!

3. Configure source code to make packing available (optional, only required for packaging if it fails)

If you want to package the project using this Plugin, there is a small change in the source code you need to add.

  • Go to CoreRedirects.cpp in UnrealEngine/Engine/Source/Runtime/CoreUObject/Private/UObject/CoreRedirects.cpp
  • Search after STRUCT_REDIRECT("AnimNode_ModifyBone", "/Script/AnimGraphRuntime.AnimNode_ModifyBone");
  • Add directly below that line the following line
STRUCT_REDIRECT("AnimNode_ModifyBones", "/Script/URoboViz.AnimNode_ModifyBones");
  • Rebuild the project
