Command Line Arguments
The Command-Line control is used to set the Command Arguments for the current project when running a
debugging session. This is a shortcut to setting them through the project Properties. In fact, changes
made here will be reflected automatically in the Properties, and vice versa.
Enter the arguments in the text box or choose from a list of recent arguments using the dropdown list. These will be passed to the executable when a debugging
session is started.
Project configs for game projects that build Unreal Editor add the project name to the command line automatically to tell the editor executable which project you are using.
For example, if you build QAGame using the build config 'Debug Editor', the command line will have QAGame.uproject added to the command arguments without needing to type it in the box.
To launch the editor for QAGame, you can leave the Command-Line control empty and the editor will still know which project you are running.
See Command-Line Arguments for a listing of all available arguments.
