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, rather than setting them through the project
Properties. In fact, changes
made here will be reflected automatically in the
Enter the arguments in the text box, or choose from a list of recent arguments using the dropdown list. These arguments will be passed to the executable when a debugging
session is started.
Project configurations 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 the need 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.
