Registering Gems to a Project
Open 3D Engine (O3DE) includes many Gems that extend features and add assets to your project. For a full list, refer to the Gem Reference . These Gems have already been registered to the engine and are ready to be added to a project.
You can also register external Gems from a source outside of O3DE so that they too can be used in your project. Registering a Gem enables your project to find the Gem. Gem folders can be located anywhere on your computer.
After you’ve registered a Gem, you can enable it for use in your project. Refer to Adding and Removing Gems in a Project for instructions on enabling or disabling a Gem.
To register a Gem to your project:
Open a command prompt to the folder where your engine lives.
Use the following command to register a Gem to your project. This command verifies that the specified Gem path contains a valid
gem.jsonconfiguration file before registering the Gem to your project. When the Gem is registered to your project, the Gem path is added to your project’s
project.jsonconfiguration file in the
scripts/o3de register -gp <gem-path> -espp <project-path>
There are short and long notations of the options that you can use to specify the path of the Gem and project.
--gem-path: Path to the Gem folder (can be absolute or relative).
--external-subdirectory-project-path: Path to your project folder (can be absolute or relative).
To deregister a Gem from your project, add the
--remove option to the command for registering a Gem. This removes the Gem path from your project’s
project.json configuration file in the
scripts/o3de register -gp <gem-path> -espp <project-path> --remove
