The manuel has the most recent copy of these commands although these arn't all of them this is an old copy of the manuel, here are the commands they give...

Command line options
The same command line options are valid for the EXE runtime engine as well as for the ACKNEX.EXE development engine. Thus the published game can be started with the following command line options, given behind the name of the EXE module:


-black
This command line option sets the startup window to a red text on black background. Otherwise it's a black text on white background. If an acknex.wdf file is found in the game folder, the window definition in this file overrides the option (Professional Edition only).


-CL
Joins to a multiplayer session in client mode.

From Edition:
A5 Commercial Edition

-CRD number
The 3D card with the given number will be selected, instead of the default one. This is useful for systems with more than one 3D card. Only active 3D devices will be selected. The order or the cards is not determined, so for selecting a second card sometimes "1" and sometimes "2" must be given. The startup message will give the name of the card.


-d name[,value]
Defines the given name for further evaluation in the script through IFDEF. This has the same effect as giving DEFINE name; or DEFINE name,value; within the script. Note that in the second case there must be just a comma, and not any spaces between name and value in the command line. This way, arbitrary game options, like starting screen resolution, difficulty grade etc., can be set via the command line.


-diag
Outputs diagnostic messages into the acklog.txt file in the current folder. When starting in dedicated server mode (-sv), the -diag output is printed into a server console window. This way it's possible to observe on the server which clients connect or leave, and what's happening in the game.


-DIR name
Gives the folder defined for saving games and screenshots; will override any SAVEDIR name defined in the script.


-IP name
Through the -IP command line option the server name, the server's machine name, domain name or IP address can be given when starting a client in multiplayer mode. Example:

acknex office -cl -ip 169.254.73.28

connects to the server with the given IP address on the network or internet. The given name or address is available during gameplay in the predefined server_name string. If this command line option is not given, the server will be searched on the local network.


-nc
The -nc command line option prevents the engine from checking itself for possible virus or hacker tampering at game start. This way, the EXE can be 'wrapped' into another program for using the registration or unlock feature of some distribution channels.

From Edition:
A5 Professional Edition

-NJ
Disables the Joystick.


-NM
Disables the mouse.


-NX number
Size of the nexus in megabytes. When you set the nexus in Map Properties, WED uses this command line option to transfer the nexus size to the engine. The nexus is the internal data structure for picture rendering. The nexus size depends on the size and complexity of the biggest level of the game. The bigger the nexus, the more complex scenes may be shown, and the more entities can be used - but the more virtual memory is used - if real memory is not available, it's taken from the harddisk. The default value for the nexus is 40 megabytes. A nexus too small for a scene can cause a sudden frame rate drop, or even give an engine error message. If you ever encounter a "Nexus too small" message, the engine must be run with a nexus size higher than that you've used before (e.g. -NX 80 for 80 MB nexus size).


-PL name
By this option an individual name can be given to each client in a multiplayer system (up to 16 characters). Otherwise the engine will generate a client name. During gameplay the name is available in the player_name string.


-PORT number
Through this command line option, a port address for TCP/IP client/server communication can be given. Valid ports are in the range 2300..2400. If no port is given, a default port address is assigned. A port address can only be given for the server - the client will connect to the right port automatically.


-S3d
Activates the Direct3D software renderer. The software renderer is dead slow, but can be used for taking screenshots, or for determining whether a certain visible fault is caused by the engine or by the D3D card driver.


-SN name
Through this command line option the session name can be given when starting a server or a client in multiplayer mode. The default session name is the name of the main script file without extension, e.g. "office" for starting the office.wdl. The given name or address is available during gameplay in the predefined session_name string.


-SV
Starts a new multiplayer session in server mode. When used in combination with -cl, the server is a client at the same time. Stand alone server mode is only supported by the Professional Edition.

From Edition:
A5 Commercial Edition

-W3D
Will force weak D3D mode, even when the 3D card pretends to support multiple textures. This way even very old 3D cards with faulty drivers can be forced to run. The graphics quality is inferior in this mode. See section about 3D hardware (link!).


-WND
Will start in window mode instead of fullscreen mode. As long as you haven't redefined the ON_ENTER function, you can always switch between window and fullscreen mode by [Alt-Enter].
