What is a command line argument?

Command line arguments are special instructions that can be passed to Collapse when launching it. They can temporarily change Collapse's behaviour at start-up. Only one argument can be used per launch.

To use a command line argument, you can either:

• Use a terminal and add it after the executable.
  (e.g., CollapseLauncher.exe tray)

• Use Windows' Run window or a web browser to call Collapse's URL Protocol.
  (e.g., collapse://tray)

tray

open

Loads a specific game/region when launching Collapse.

Options

REQUIRED

• -g <game name/ID> or --game <game name/id>
  Specifies the game to load.
  If invalid, the entire command will be ignored.

OPTIONAL

• -r <region name/id> or --region <region name/id>
  Specifies the region to load.
  If not specified or invalid, the last opened region for the game will be opened.

Notes

• If the game/region name has spaces, the name must be enclosed by quotes.
• The ID of a game/region corresponds to their position in the Launcher Selector (being the first game/region at position 0). Some examples of IDs are:

collapse://open -g "Honkai: Star Rail" -r Bilibili

• Load and start Honkai Impact 3rd (Southeast Asia region)
