Command Line Arguments

Overview

Sandbox accepts most of the same command line arguments as Launcher.exe, and also has the additional ability of loading .cry files parsed in the first parameter.

Command Line Arguments Example

The following input:

Launcher.exe -Arg1 -Arg2 ParamOfArg2 +Arg3 Param1OfArg3 Param2OfArg3 +Arg4 "ParamOfArg4" +Arg5 4-3+2 -Arg6

... will result in the following pre-commands (starting with a minus symbol (-); modify the startup behavior):

Arg1 Arg2 ParamOfArg2 Arg6

... and the following post-commands (starting with plus symbol (+); executed as console commands after initialization; all in the same frame):

Arg3 Param1OfArg3 Param2OfArg3
Arg4 "ParamOfArg4"
Arg5 4-3+2

Recognized Pre and Post Commands

Below you'll find a list of command-line arguments. If you have Engine and Game code, searching for "eCLAT_Pre" and "eCLAT-Post" should give you all of the available arguments.

PRE Commands	Usage (Prefixed with "-")	Description
DEVMODE	Editor.exe -DEVMODE	DEPRECATED - Devmode is enabled by default in all modes except for Release Pure-Game. In DEVMODE, the lua debugger is disabled and the pak file system now prefers files outside the pak files. The LUA command execution in the console is now allowed (by using the # prefix). CVars marked with the Cheat flag can be changed.
nodevmode	GameSDK -nodevmode	Disable devmode in pure-game mode, even in non-release builds.
DX9	Editor.exe -DX9	DEPRECATED - Use Direct3D 9 renderer (override the system.cfg setting).
DX11	Editor.exe -DX11	Use Direct3D 11 renderer (override the system.cfg setting).
MOD	Editor.exe -MOD MyMod	Loads a MOD DLL, instead of the standard game code. Adds the folder of the MOD to the data directories to search in. MODs must be located in the `<root>\Mods` directory.
root	Editor.exe -root RootFolder	Overrides the default folder for log files (also, LogBackups), cfg files (for the exec command), and level rotation files. This command line option is mostly used for 3rd party hosting, with multiple instances on the same machine support.
nomouse	Editor -nomouse	Disable mouse input.
lua_storedebug	Editor -lua_storedebug
noprompt	Editor -noprompt	Disable the message box.
