Command line switches

This article is a stub. You can help this wiki by expanding it.

Supreme Commander will accept many command line switches. You can set them up in your windows shortcut, or in your GPGnet settings under Tools -> Options -> Supreme Commander -> Command Line Arguments. This is a partial list, with some explanations.

Setting up a skirmish using command line

Standard switches

You can automaticly launch a skirmish right after launching the game. To do that, you need to specify a map. The other switches are optionals.

• /map map_folder

Set the map

• /faction faction

Set your faction

1 = UEF

2 = Aeon

3 = Cybran

• /victory "victory_condition"

Set victory conditions

demoralization = Assassination

domination = Supremacy

eradication = Annihilation

sandbox = Sandbox

• /nofog

Set fog to None

• /blackfog

Set fog to Unexplored

• /predeployed

Set pre-build units to On

Example: SupremeCommander.exe /map SCMP_019 /faction 3 /nofog /victory "domination"

Custom switches

You can create your own switches :

1. hook lua/SinglePlayerLaunch.lua
2. go to line 175
3. add your switch detection code

Example:

if HasCommandLineArg("/gamespeed") then

options['GameSpeed'] = GetCommandLineArg("/gamespeed", 1)[1]

end

This will allow you to adjust game speed with the following switch :

• /gamespeed "gamespeed"

Set game speed ("normal", "fast" or "adjustable")

Other switches

/aqtime

/audition

/bugreport

/data

/debug

Opens the debugging tool at startup

/D3D10

/EnableDiskWatch

The game engine will monitor all files on the disk, and if it detects a change, it will attempt to re-load that file immediately, if possible. This allows instant in-game updates of things like unit blueprints.

/edit

/exitongameover

Application will exit when the game is over

/file

/framerate

/genpath

/gpgnet

/gpgnetdev

/hook

/hostgame

/init

/interlocked

/joingame

/load

/loadrulesandexit

/log "log_file"

Logs messages to the given file.

/mediacenter

/networksafe

/nobugreport

/noinitialunits

/nologbox

/nomass

/nomovie

Disable all pre-rendered movies

/nomusic

Set music to Off

/noprops

/nosound

/replay "replay_file"

Plays the given replay file. Example: /replay "C:\My Replays\Me vs The Bad Guys.SupremeCommanderReplay"

/savereplay "replay_file"
