Project Setup

Linux

0- Create Epic Games Account

In order to access Unreal Engine Source code you have to request access it.

(If you have problems ask me - Ugurkan)

1- Download Unreal Engine 4.25

Notice : It will take 10GB of download. If you have slow internet do execute this command before you go sleep and don't turn off your PC.

git clone -b 4.25 https://github.com/EpicGames/UnrealEngine.git
cd UnrealEngine
./Setup.sh
./GenerateProjectFiles.sh
make

After git clone rest will also take 2 hours to build(depending on your RAM-CPU Speed)

Congrats you have now Unreal Engine 4.25 built from source code.

2- Install AirSim and Build It

Clone AirSim and build it:

# go to the folder where you clone GitHub projects
git clone https://github.com/Microsoft/AirSim.git
cd AirSim


./setup.sh
./build.sh

3- Test your Install

Go to UnrealEngine installation folder and start Unreal by running ./Engine/Binaries/Linux/UE4Editor.

When Unreal Engine prompts for opening or creating project, select Browse and choose AirSim/Unreal/Environments/Blocks (or your custom Unreal project).

Alternatively, the project file can be passed as a commandline argument. For Blocks: ./Engine/Binaries/Linux/UE4Editor <AirSim_path>/Unreal/Environments/Blocks/Blocks.uproject

If you get prompts to convert project, look for More Options or Convert-In-Place option.

If you get prompted to build, choose Yes. If you get prompted to disable AirSim plugin, choose No.

After Unreal Editor loads, press Play button.

Windows

BEFORE START INSTALL GIT and CMAKE

https://git-scm.com/download/win 64 bit Windows Setup ( not the portable one )

CMake download page: https://cmake.org/download/

You can install CMAKE by following the instructions in this video https://www.youtube.com/watch?v=8_X5Iq9niDE

0- Create Epic Games Account

If you don't have one already.

1- Install Epic Games Store

https://www.unrealengine.com/en-US/download/creators?install=true

Choose "Creators" license.

2- Install Unreal Engine 4.25 from Epic Games Store

From launcher SELECT UNREAL ENGINE 4.25 definitely not select 4.26 or newer.

If you can't see it let us know !

3- Download Airsim

  • Install Visual Studio 2019. Make sure to select Desktop Development with C++ and Windows 10 SDK 10.0.18362 (should be selected by default) while installing VS 2019.

  • Start Developer Command Prompt for VS 2019. Clone the repo: git clone https://github.com/Microsoft/AirSim.git, and go the AirSim directory by cd AirSim.

Note: It's generally not a good idea to install AirSim in C drive. This can cause scripts to fail, and requires running VS in Admin mode. Instead clone in a different drive such as D or E.

  • Run build.cmd from the command line. This will create ready to use plugin bits in the Unreal\Plugins folder that can be dropped into any Unreal project.

4- Test Install

  • Navigate to folder AirSim\Unreal\Environments\Blocks and run update_from_git.bat .

  • Double click on generated .sln file to open in Visual Studio 2019 or newer.

  • Make sure Blocks project is the startup project in Unreal Engine.

  • Make sure build configuration is set to DebugGame_Editor and Win64 in Visual Studio. Hit F5 to run. This should open blocks project in Unreal Engine.

  • Press the Play button in Unreal Editor and you will see something like this,

Note: If Unreal Editor asks you to "Choose Vehicle" just click "No" to select drone.

If you see a drone, you have finished the installation successfully!

Note: If you see a gray screen after pressing the play button, just wait a few minutes for loading the assets then you can see the environment and a drone.
