You can set-up your own Unreal Environment with these instructions.

For this tutorial, we will use a simple block environment.

Blocks environment is available in repo in folder Unreal/Environments/Blocks and is designed to be lightweight in size. That means its very basic but fast.

Here are quick steps to get Blocks environment up and running:

Windows

  1. Make sure you have installed Unreal and built AirSim.

  2. Make sure you have uproject files are associated with Unreal engine

    • After installation of Unreal, Restart computer

    • Open Epic Game Launcher -> Unreal Engine -> Unreal Engine 4.24.x

      epic1

    • Associate uproject with Unreal engine

      epic1

  3. Open Command Prompt for VS 2019 and navigate to folder AirSim\Unreal\Environments\Blocks and run update_from_git.bat. Or you can run update_from_git.bat by double clicking the file in File Explorer

  4. With File Explorer, double click on generated .sln file to open in Visual Studio 2019 or newer.

  5. Make sure Blocks project is the startup project. Click the right mouse button and select Startup project.

Changing Code and Rebuilding

For Windows, you can just change the code in Visual Studio, press F5 and re-run. There are few batch files available in folder AirSim\Unreal\Environments\Blocks that lets you sync code, clean etc.

FAQ

I see warnings about like "_BuitData" file is missing.

These are intermediate files and you can safely ignore it.
