View source for Command-Line Reference

==Launcher Flags==
The following command-line options can be chosen from the launcher.  
===Graphics===
====-spec====
Enables specular mapping.  Only polygons mapped with textures for which a shinemap exists will recieve specular lighting.  Specular maps are specified with the base map name plus "-shine" (i.e. TCov3A-shine.pcx).
====-glow====
Enables glowmapping.  Only polygons mapped with textures for which a glowmap exists will be glowmapped.  Glow maps are specified with the base map name plus "-glow" (i.e. TCov4A-glow.pcx)

====-jpgtga====
Enables the use of TGA and JPG file formats for image files.  If a ship is showing up partially invisible, select this option.
====-pcx32====
'''WARNING - HIGH MEMORY USAGE'''

Enables PCX files to be loaded into 32-bit memory.  This will not imporove the rendering of any ships in-game, and is usually more of a burden on performance than is worthwhile.  Use at your own risk.  Removed from launcher options after 3.6.7.

====-cell====
Enables cell shading.  This will make graphics appear more "cartoonish".  For use with media in mv_cell.vp.  Not considered a standard enhancement.
====-mipmap====
Enables mipmaping.
====-nomotiondebris====
Disables motion debris.
====-2d_poof====
Applies nebula poofs in 2d, effectively preventing them from forming intersections with ships.
====-noscalevid====
Disables scaling of video clips.
====-cache_bitmaps====
Caches bitmaps between missions, which will ideally reduce the load-time from one mission to another.
====-rlm====
'''Obsolete Argument'''

<font color=yellow>
Enables more accurate lighting model for OpenGL mode.  Always on in current builds, so this command-line option has been removed.</font>

----

===Game Speed===
====-img2dds====
Converts all images to DDS (compressed) format.  Decreases memory usage but potentially reduces image quality.
====-no_vsync====
Disables vertical sync.

----

===HUD===
====-dualscanlines====
Adds a second pair of scanning lines to the target window when scanning an object.
====-targetinfo====
Displays target info, such as name and class, beside the targeted object.
====-orbradar====
Enables 3D radar (the Orb).  3D radar will replace the standard 2D version.
====-ballistic_gauge====
Adds an ammo gauge to the HUD when armed with a ballistic weapon.

----

===Gameplay===
====-nobeampierce====
Causes beams to hit (and damage) shields before they impact a ship's hull.  This is a global flag, but this behavior can also be modified in weapons.tbl.
====-smart_shields====
Enables "smart" shield recharging.  Shield recharge rate is distributed across all damaged quadrants only, so each quadrant will recharge faster if not all are damaged.
====-ship_choice_3d====
Use ship and weapon models in ship selection and weapon loadout.  Completely disables the standard ANI interface on those screens.
====-3dwarp====
Use full geometry for the subspace warp effect.
====-warp_flash====
Enable a flash at warp in and warp out.
====-UseNewAI====
Tells the game to use new AI routines.  This argument alters mission balance and is not considered a standard feature.
====-tbp====
Enable feature set for The Babylon Project
====-wcsaga====
Enable feature set for The Wing Commander Saga

----

===Audio===
====-snd_preload====
Preload mission sounds.  Useful in preventing game stuttering when sounds are played for the first time.
====-nosound====
Disables all sounds.
====-nomusic====
Disables music only.
===Multiplayer===
====-standalone====
Creates a standalone server.
====-startgame====
'''''What does this do?'''''
====-closed====
'''''What does this do?'''''
====-restricted====
'''''What does this do?'''''
====-multilog====
'''''What does this do?'''''
====-clientdamage====
'''''What does this do?'''''
====-mpnoreturn====
Disables return to the flight deck screen after a mission completes.

----

===Troubleshooting===
====-fixbugs====
'''Obsolete Argument - Removed in builds after 3.6.7'''

<font color=yellow>
Originally used to disable certain crashing behavior as a stop-gap measure.  This feature is not available in current builds.</font>
====-nocrash====
'''Obsolete Argument - Removed in builds after 3.6.7'''

<font color=yellow>

====-oldfire====
'''''What does this do?'''''
====-nohtl====
'''WARNING - VERY SLOW'''

Reverts to software rendering mode.  Does this work any more?
====-no_set_gamma====
Disables the gamma settings in the options screen.
====-nomovies====
Disables all video playback.
====-noparseerrors====
Disables some parsing warnings and makes other parse errors non-fatal.  Do not rely on this when creating new tables, the errors are there for a reason.
====-safeloading====
Loads missions the old way.  Typically safer, but slower.
====-query_speech====
Determines if the current build includes text-to-speech.
====-d3d_bad_tsys====
Enable inefficient texture system.
====-novbo====
Disables OpenGL VBO.
====-noibx====
Disables IBX caching of model geometry data.  This will dramatically increase load times, but will help troubleshoot a model if one is working incorrectly.
====-loadallweps====
Load all weapons, even those not used.

----

===Experimental===
====-env====
Enables environment mapping.  Direct3D only.  Environment mapping intensity will be determined from the intensity of specular maps.
====-alpha_env====
Enables alpha environment mapping.  Direct3D only.  Environment mapping intensity will be determined from the alpha channel of specular maps.
====-decals====
Enables damage decals.
====-ingame_join====
Enables ingame joining in multiplayer.  FIXME: Host option?
====-tga16====
Converts all TGA images to 16-bits.  Reduces memory footprint at the expense of image quality.

----

===Development Tools===
====-fps====
Displays current frames per second.
====-pos====
Displays current position coordinates of camera.
====-window====
Runs the game in a window.  No check to make sure that resolution is no higher than your desktop resolution, so be careful.
====-timerbar====
Displays a timing bar across the top of the screen.  Timebar format varies by build.
====-stats====
Shows statistics.
====-coords====
Shows coordinates of the mouse cursor.
====-show_mem_usage====

==Other==
The following options are not available as checkboxes in the launcher.  Many require parameters, which follow the flag seperated by a space.  The prototype for use in this case is "-option argument"
===Graphics===
====-ambient_factor====
Reduces the ambient lighting levels.

Takes one argument decimal.  The range is specified as a percent, so 0 is no ambient lighting, 100 is default levels.
====-spec_exp====

Takes one argument decimal.

Changes the distance from the viewpoint for the near-clipping plane.

Takes one argument decimal specifying the distance to the near-clipping plane.

----

===Gameplay===
====-mod====
Specifies a higher priority game directory.

Takes one argument string, the name of the directory in which the target mod is contained.  Explicit use of this command line should be unnecessary as the launcher has MOD options, though multiple mods are supported and do require manual entry.

Data precidence with -mod is as follows (mod directory "moddir")
#moddir/data/(appropriate directory)/
#moddir/data/
#moddir/
#Freespace2/data/(appropriate directory)
#Freespace2/data/
#Freespace2/
====-fov====
Specifies the Field of View for the player eyepoint.

Takes one argument decimal specifying the angle of the viewing cone.  FIXME: Is this a solid angle, or a width?  Is it radians or degrees?  What is the valid range of inputs?

----
