Visit the JFShadowWarrior website for the latest information. The source code for JFShadowWarrior can be found in this Git repository.

# System Requirements

At minimum, you need:

- 64-bit Intel, AMD, or compatible CPU
- OpenGL 2.1 capable GPU
- (Windows) Vista or newer (7, 8, 10)
- (Mac) macOS 10.9 (Mavericks) or newer

Additionally, these platforms and architectures are supported when building from source code:

- 32-bit Intel/AMD, and 32 or 64-bit ARM CPUs
- OpenGL ES 2.0 capable GPUs, e.g.
  - Broadcom VideoCore IV (tested with Raspberry Pi 3 B+)
  - ARM Mali-T860 (tested with Libre Computer ROC-RK3399-PC)

# Installation and Setup

After unzipping the JFShadowWarrior package somewhere on your computer, run the main executable: `JFShadowWarrior.app` on macOS, `sw.exe` on Windows. You ought to see the startup window open at the Game tab.

Windows, Linux and BSD (if built with GTK support) have similar startup windows with the same options.

You will now need to import the game data from a commercial release or the shareware version of Shadow Warrior as the game will not work without it.

1. Click the "Choose a location..." button, then navigate to a location where Shadow Warrior data can be found.
2. Choose a folder and JFShadowWarrior will then scan the location you've selected, copying any compatible game data it finds.

Where game data files are stored by JFShadowWarrior depends on the operating system you are using:

- (Linux, shared with all users) `/usr/local/share/games/jfsw`
- (Linux, single user) `~/.jfsw`
- (macOS, single user) `~/Library/Application Support/JFShadowWarrior`
- (Windows) wherever you've put sw.exe

Below are known locations of Shadow Warrior game data for various sources:

MS DOS Registered version CD-ROM
  In the `SWINST` directory of the disc.
Classic Redux from GOG on macOS
  To be determined.
Classic Redux from Steam on macOS
  In Steam, go to Shadow Warrior Classic Redux, open the 'gear' menu, choose Manage > Browse local files. Make note of this location to use for importing.
Classic Redux from Humble
  To be determined.
Classic Complete from GOG.com on macOS
  In GOG Galaxy 2, go to Shadow Warrior Classic Complete, open the 'options' menu (beside Play), choose Manage installation > Show folder. Make note of this location to use for importing.
Classic (1997) from Steam on macOS
  In Steam, go to Shadow Warrior Classic (1997), open the 'gear' menu, choose Manage > Browse local files. Make note of this location to use for importing.
MS DOS Shareware version

  If you have downloaded an original 3D Realms distribution file named `3DSW12.ZIP`:

  1. Unzip `3DSW12.ZIP` to obtain the `SWSW12.SHR` file.
  2. Rename `SWSW12.SHR` to `SWSW12.ZIP`, then unzip it.

  Alternatively, you can fetch swsw12.zip authenticity-intact from my site ready to unzip and point JFShadowWarrior at for importing.

## CD Music

Music from the retail Shadow Warrior CD can be ripped and encoded to Ogg Vorbis format files, and JFShadowWarrior can play those files in place of having the original game CD in the system CD drive. Each track should be named `trackNN.ogg`, NN being the track number 0-padded to two digits, and placed beside the `sw.grp` file in the game data location mentioned above.

## "Portable" Installation

Typically the game will store its configuration information and saved games in a private location for your user account:

- (Linux) `~/.jfsw`
- (macOS) `~/Library/Application Support/JFShadowWarrior`
- (Windows) `C:\Users\your-name\AppData\JFShadowWarrior`

To have the game instead store these files in the working directory where the game was started, create an empty file named `user_profiles_disabled` (no extension) beside the executable. You can put the `sw.grp` file in the same location, thus making everything self-contained and 'portable'.

# Multiplayer

Multiplayer games can be started from the startup window, or for more specialised situations, with command-line parameters passed to the game.

From the startup window, one player should choose "Host multi-player game" and select the number of players, then press Start to begin waiting. The other players should choose "Join multi-player game" and enter the hostname or IP address of the system hosting the game, and then press Start. The game will proceed once all players are joined.

Windows, Linux and BSD (if built with GTK support) have similar startup windows with the same options.

The game communicates on UDP port 23513 by default, so if you intend to play across the Internet you may need to forward that port through relevant firewalls of the system hosting the game.

## Command-line launching

The general command line syntax to use on each platform is:

- (Linux, in a terminal) `/path/to/jfsw/sw [options] -net [net options]`
- (macOS, from a Terminal window) `open /Path/To/JFShadowWarrior.app --args [options] -net [net options]`
- (Windows, from a Command Prompt window) `x:\path\to\jfsw\sw.exe [options] -net [net options]`

Multiplayer games can use either of two communication modes: hosted (a.k.a. master/slave mode) and peer-to-peer. Peer-to-peer is more difficult to use over the Internet and more troublesome to correctly configure. In all modes you must know the exact number of players as the game will not start until all players are present.

## Hosted (master/slave) mode

Choose a system to be the host of the game, and each other player will connect to that host.

The "net options" for this mode are:

- `-pportnum` — host the game on a different UDP port to the default 23513.
- `-nm` — be host of a 2-player game.
- `-nm:num` — be host of a num-player game.
- `-nm host-name-or-ip` — join a game hosted by host-name-or-ip.
- `-nm host-name-or-ip:port` — join a game hosted by host-name-or-ip on non-default port port.

For example, a three-player hosted game is launched like so:

1. (Player 1, hosts) `sw -name Player1 -net -nm:3`
2. (Player 2, joins) `sw -name Player2 -net -nm host1`
3. (Player 3, joins) `sw -name Player3 -net -nm host1`

## Peer-to-peer mode

In this mode each player sends data to each other player in the game directly, which is only really practical in non-firewalled LAN-like environments. The list of peers specified on the command line must be consistently ordered amongst all players, and each peer will launch the game with slightly different options.

The "net options" for this mode are:

- `-pportnum` — communicate with other peers on a different UDP port to the default 23513.
- `-np ordered-peer-list…` — participate in a peer-to-peer game.
- `.` or `*` — identify the local machine in the ordered peer list.
- `host-name-or-ip` — identify a peer at host-name-or-ip in the ordered peer list.
- `host-name-or-ip:port` — identify a peer at host-name-or-ip on non-default port port in the ordered peer list.

For example, a three-player peer-to-peer game is launched like so:

1. (Player 1) `sw -name Player1 -net -np . host2 host3`
2. (Player 2) `sw -name Player2 -net -np host1 . host3`
3. (Player 3) `sw -name Player3 -net -np host1 host2 .`

# Customisation File Format

Historically, modifications and total conversions for Shadow Warrior have been required to hack a copy of the game executable to replace the names of maps and the episode title information. JFShadowWarrior introduces a customisation script file that is loaded on startup to achieve the same end.

The customisation file should be named `swcustom.txt` and its contents may consist of the directives below. Comments can be used by prefixing the text with a `//` (C++ style), or surrounding the text with `/*` (comment here) `*/` (C style).

map number { ... }
level number { ... }

  description title
    Sets the new title of the level to title. name and description are synonyms for title.
  filename filename
  file filename
  fn filename
  levelname filename

# Console Commands

This is a list of more useful console commands and settings and their purpose:

clear
  Clear the console.
glinfo
  Displays some information about the OpenGL driver. Use "glinfo exts" to display supported OpenGL extensions.
glmultisample <0, 1, 2, …>
  Enable OpenGL multisample antialiasing. 0 disables it. You need to use "restartvid" to apply any changes to this value.
gltextureanisotropy <level>
  Sets the OpenGL anisotropic filtering level. The default is the highest level supported by the hardware.
gltexturemode <mode-number>
  Sets the OpenGL texturing mode. Valid values are:

  0 | GL_NEAREST
  1 | GL_LINEAR
  2 | GL_NEAREST_MIPMAP_NEAREST
  3 | GL_LINEAR_MIPMAP_NEAREST (bilinear)
  4 | GL_NEAREST_MIPMAP_LINEAR (gives an unfiltered appearance like the original software renderer)
  5 | GL_LINEAR_MIPMAP_LINEAR (trilinear, the default)

glusetexcompr <0 or 1>
  Enables or disables the use of OpenGL texture compression for replacement textures. You need to use "restartvid" to apply any changes to this value.
help <name>
  Displays a help message for a particular console variable or command.
listsymbols
  Displays the names of all commands and variables available in the console.
novoxmips <0 or 1>
  Disables or enables the use of voxel mipmaps to improve voxel visual quality.
osdrows <num>
  Sets the number of visible lines of the console when it is open.
restartvid
  Reinitialise video to apply settings changes.
screencaptureformat <0 or 1>
  0 = Targa, 1 = PCX
usegoodalpha <0 or 1>
  If 1, a lower alpha cutoff value is used when rendering textures with transparency, which gives better looking transparent textures at the expense of some sprites behind the transparent item potentially being invisible in certain circumstances. 0 is a more compatible value (and is the default) for this option but slight visual degradation will result.
vidmode <bpp>
vidmode <xdim> <ydim> [bpp [fs]]
  Change the video mode. xdim ydim are the resolution. bpp is the colour depth (8, 16, 24, 32). fs is 0 for windowed, 1 for fullscreen.
