Using Custom Worlds

If you have built a custom Unreal world using the Holodeck backend you can now follow this tutorial to use it for training agents from the python bindings.

Packaging

Before packaging the project, ensure that you have completed the following:

• You have followed the pre-build checks
• You know the names of the levels and agents in the world that you plan to use
• If you are packaging for linux you have followed this tutorial

Go to File>Package Project>operating system to package. After packaging, you should have a directory called WindowsNoEditor or LinuxNoEditor depending on what OS you packaged it for.

Using the Packaged World

Now a config file must be written to inform the python bindings about each level in your world. Follow the json format to write the config file. When finished, put both the config file and the NoEditor folder in a directory called WindowsDefaultWorlds or LinuxDefaultWorlds.

The worlds are stored in the location Users/User/Local/AppData/Holodeck for Windows and home/user/.local/share/holodeck for Linux. If the holodeck directory doesn't exist, create it. Move the WindowsDefaultWorlds or LinuxDefaultWorlds into the holodeck directory.

You can now use env = Holodeck.make("YOUR_MAP_NAME") to run your custom world!
