Build AirSim on Linux

The current recommended and tested environment is Ubuntu 18.04 LTS. Theoretically, you can build on other distros as well, but we haven't tested it.

We've two options - you can either build inside docker containers or your host machine.

Docker

Please see instructions here

Host machine

Pre-build Setup

Build Unreal Engine

  • Make sure you are registered with Epic Games. This is required to get source code access for Unreal Engine.

  • Clone Unreal in your favorite folder and build it (this may take a while!). Note: We only support Unreal >= 4.27 at present. We recommend using 4.27.

# go to the folder where you clone GitHub projects
git clone -b 4.27 git@github.com:EpicGames/UnrealEngine.git
cd UnrealEngine
./Setup.sh
./GenerateProjectFiles.sh
make

Build AirSim

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

By default AirSim uses clang 8 to build for compatibility with UE 4.27. The setup script will install the right version of cmake, llvm, and eigen.

./setup.sh
./build.sh
# use ./build.sh --debug to build in debug mode

Build Unreal Environment

Finally, you will need an Unreal project that hosts the environment for your vehicles. AirSim comes with a built-in "Blocks Environment" which you can use, or you can create your own. Please see setting up Unreal Environment if you'd like to setup your own environment.

How to Use AirSim

Once AirSim is setup:

  • 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.

See Using APIs and settings.json for various options available for AirSim usage.

!!! tip Go to 'Edit->Editor Preferences', in the 'Search' box type 'CPU' and ensure that the 'Use Less CPU when in Background' is unchecked.

[Optional] Setup Remote Control (Multirotor Only)

A remote control is required if you want to fly manually. See the remote control setup for more details.

Alternatively, you can use APIs for programmatic control or use the so-called Computer Vision mode to move around using the keyboard.
