----------------------------------------


Welcome to X-Wing Revival!  I started making this because I wanted to have an X-Wing LAN
party in 2011, and found that X-Wing Alliance (released in 2002) didn't run correctly on
modern PCs.  We've come a long way since then!  The goal is still to recreate the feeling
of a classic LucasArts X-Wing game, but X-Wing Revival has developed into its own unique
take on the genre, with a focus on fast dogfighting, epic battles, multiplayer balance,
and staying true to classic Star Wars ship designs.  (TIE Fighters don't have missiles!)

== CREDITS AND THANKS ==

Ship models were shamelessly pilfered from X-Wing Alliance asset files, including many
beautiful high-res models from the X-Wing Alliance Upgrade Project.

Special thanks to NoJoe, Peter, and Sawyer for all the test flights, and to The Rebel
Alliance for helping me bring balance to the forces.

== GAME TYPES ==

  Fleet Battle: Each team tries to destroy the enemy capital ships while defending
    their own.  The last team with any surviving capital ship wins.  Respawn is only
    possible while your team's flagship is alive, so prioritize its protection.
    Cruisers and Battleships will respawn if their entire group is destroyed before
    the flagship, but it takes time to replace a large group of capital ships.

  Battle of Yavin: Rebels must fly down the trench and try to hit the exhaust port
    with a pair of proton torpedoes.  Imperials must try to prevent the Rebels from
    doing this before the time limit runs out.  Harder AI skill effects turrets too!

  Flagship Hunt: The attacking team must destroy the defending team's flagship before
    the time limit runs out.  (This mode was previously called "Capital Ship Hunt".)

  Team Deathmatch: The team to hit the kill limit first wins.  Respawn always enabled.

  Team Elimination: The last team with any ships remaining wins.  Players can control
    AI ships when the player's ship has been destroyed, but no new ships will be given
    to either team once the match has started.

  Team Kessel Run: Race through the asteroid field, gaining points for your team with
    each checkpoint reached.  First team at the score limit (or last team alive) wins.

  FFA Deathmatch: The player to hit the kill limit first wins.  Respawn always enabled.

  FFA Elimination: Last man standing wins, and there's no respawn whatsoever.

  FFA Kessel Run: Race through the checkpoints in the asteroid field.  First player to
    reach the score limit (or last player alive) wins.  Basically Carmageddon in space.

  Mission: Play a campaign level or custom scripted mission.


== TROUBLESHOOTING / FAQ ==

Textures are blank.  Everything looks like white boxes!

  Windows: This is a directory permissions problem.  This often happens on Windows 10/11
    if you attempt to unzip X-Wing Revival in your Downloads folder or on the desktop.

    The solution is to move the zip file to a different directory like "C:\Program Files"
    before extracting it.

  Mac: This is usually caused by the Quarantine file system attribute, which prevents a
    downloaded program from reading files, even if they were extracted from the same zip.

    The solution is to open Utilities/Terminal and remove the Quarantine flag from the
    directory you extracted X-Wing Revival to:

      xattr -dr com.apple.quarantine "/Applications/X-Wing Revival"

My OS warns about or won't allow a downloaded or unsigned application to run.

  Apple and Microsoft have made it disappointingly onerous to distribute software for
  their platforms without paying them for code-signing.  Fortunately for those of us
  who still value running whatever we want on our own computers, there are workarounds.

  Windows: In the SmartScreen popup, click "More Info" at bottom, then "Run Anyway".
    The permanent fix is in Windows Security, "App & Browser Control", "Reputation-based
    protection settings".  Turn off "Check apps and files".

  Mac: You might be able to just right-click to run an unsigned app.  (Unconfirmed.)
    The permanent fix to allow apps downloaded from anywhere is done in the Terminal:
      sudo spctl --global-disable

  I recommend the permanent fixes for power users only, or anyone who misses the 90's.

Should I run "X-Wing Revival.exe" or "X-Wing Revival Legacy.exe" on Windows?

  You should try "X-Wing Revival.exe" first.  This is the 64-bit version using SDL 2.0.
    If you are on a 32-bit system or having problems that did not occur in old versions
    of X-Wing Revival, you can try "X-Wing Revival Legacy.exe" which is 32-bit SDL 1.2.
    NOTE: SDL 1.2 and 2.0 often have different joystick axis mappings, so you may
    need to alter control binds or restore defaults when switching between them.

Linux asks what application to open files of type "executable" with.

  Click Cancel, then right-click "X-Wing Revival.elf", select "Properties", then go to
    the "Permissions" tab, and check "Allow this file to run as a program".  Close this
    window.  Now double-clicking "X-Wing Revival.elf" should run it.


== PREFERENCES ==

--Graphics--

  Fullscreen: Toggle fullscreen, and set the resolution for fullscreen mode.
    Windowed resolution can be changed by dragging the lower-right corner.

  FOV: Set horizontal field of view in degrees.  Default "auto" uses vFOV 60.

  MSAA (Antialiasing): Use multiple samples to reduce jagged edges.  Can be GPU-heavy,
    especially when VR is enabled.  (Renamed from "FSAA" to avoid confusion with FXAA.)

  VSync (Vertical Synchronization): Eliminate tearing by only drawing frames when the
    monitor is ready to refresh.  Recommended for fast systems, but turning this off is
    an easy way to improve framerate and reduce stuttering.

  Framebuffer Textures: Use framebuffer objects as live textures for the cockpit.
    This shouldn't hurt performance much, but some old video cards don't support it.
    Framebuffers are also used for the VR eyes, so this is required for VR.

  Texture Quality: Limit the maximum texture resolution; downsample anything too large.
    This may improve performance with very limited VRAM and is required on some ancient
    video cards, but if your PC was made in the last 20 years you can leave this High.

  AF (Anisotropic Filtering): Improve texture clarity and detail.  Slightly GPU-heavy.
    Trilinear mode is the standard non-anisotropic mode.  Linear mode uses bilinear
    filtering without mipmapping, which looks sharp but sparkles at longer distances.

  Shaders: Use GLSL vertex and fragment shaders instead of old fixed-pipeline OpenGL.
    Recommended for performance and better appearance, but a few old motherboards may
    perform better with this off, and some ancient video cards require this off.

  Lighting: Per-pixel can be GPU-heavy, especially in VR, but looks much better on
    large surfaces like capital ships and the Death Star trench.  Requires shaders.

  Dynamic Lights: Number of point light sources (lasers, torpedos, explosions, etc) to
    use for lighting each object.  Higher values use a bit more CPU and GPU power.

  Blastpoints: Number of damage blastpoints to draw per object.  Higher values can be
    very GPU-heavy, especially at higher quality.  Requires shaders.

  Blastpoint Quality: Controls shader complexity used to draw blastpoints.  Low does
    most work per vertex.  Medium and High operate per pixel, which can be quite
    GPU-heavy when combined with high blastpoint count, anti-aliasing, and/or VR.

  Effects: Adjust the number of sprites per explosion.  Lowest removes shot impact
    effects entirely.  Most should leave this High, but lower settings may reduce
    the CPU load of dynamic lights and/or the GPU load of layered transparencies.

  Engine Glow: Draw engine glow effects.  Very little performance impact on most GPUs.

  Asteroid Level of Detail: Controls how far away asteroids render in higher detail.
    Can be somewhat CPU-heavy and GPU-heavy with many asteroids, especially in VR.
    NOTE: This is even more CPU-heavy when shaders are disabled!

  Death Star Trench/Surface: Draw 3D details over the flat surfaces of the Death Star.
    Can be somewhat GPU-heavy and CPU-heavy, especially in VR.
    NOTE: This is even more CPU-heavy when shaders are disabled!

  FPS: Show framerate (and physics rate if hosting) in bottom right.

--Virtual Reality--

  Enable VR Mode: Enable VR HMD output and seated head tracking, using OpenVR/SteamVR.
    Tested with the HTC Vive, and it should work for the Oculus Rift, Valve Index, or
    any other HMD.  Non-Vive headsets may require view tweaks below.  VERY GPU-HEAVY!

  Sway: Enable cockpit swaying motions in VR.  More immersive, but can be nauseating.

  FOVW / FOVH: Field of view in degrees; negative means vertical FOV.  Default: -111

  Eye Separation: Spacing in meters between the two eyes.  Default: 0.0625

  Center Offset: Offset in pixels from screen center to eye center.  Default: 87

--Sound--

  Volume: Master volume that affects all playback.

  Effects: Volume of sound effects.

  Engines: Engine sound volume, relative to effect volume.

  Music: Volume of all music, including end-of-round victory/defeat music.

  Menu Music: Play background music in the menus and lobby.

  Game Music: Play background music while flying.

  S.Alarm: Play alarm sound when losing a deflector shield.

--Networking--

  Rate: Send updates to the server at this rate.  Default: 30

  Predict: Shots fire immediately instead of waiting for server.  Default: All My Shots


== CONTROLS ==

  Swap Yaw/Roll: Normally X = roll and twist/pedals = yaw.  This option swaps those
    controls so the joystick points your ship and twist/pedals change your ship's roll,
    which is how classic X-Wing games were controlled.

  Invert Turrets: Normally turrets pitch the same way ships do.  This reverses them.

--Joystick--

  Deadzone: Ignore some stick/twist motion near the center to prevent drift.
    NOTE: This setting is not used for calibrated devices!

  X / Y / Twist: Sharpest is most responsive while Smoothest is least twitchy.

--Controller--

  Deadzone: Ignore some thumbstick motion near the center to prevent drift.
    NOTE: This setting is not used for calibrated devices!

  Sticks: Sharpest is most responsive while Smoothest is least twitchy.

  Triggers: Sharpest is most responsive while Smoothest is least twitchy.

--Mouse--

  Mode: Disabled: Disable mouse input in game.
  Mode: Turret Aim: Mouse does not control flight, but does aim for turret gunners.
  Mode: Yaw/Pitch: Mouse controls yaw and pitch in flight, and aims turrets.
  Mode: Roll/Pitch: Mouse controls roll and pitch in flight, and aims turrets.
  Mode: Freelook: Use mouse to look around the cockpit.

  Invert Pitch: Make mouse flying feel more like using a joystick (up = pitch down).

  Input: Sharpest is most responsive while Smoothest is least twitchy.

--Binds--

  Show Only Connected Devices: Hide control binds for devices that were not found.

  Refresh: Search again for connected joysticks.

  To rebind an analog axis, click the box and then move your joystick or controller
  axis in the positive direction (pitch up, yaw right, roll right, throttle up, etc).
  If the result is reversed from what you want, rebind it in the other direction.

  To rebind a digital control, click the box and then press the desired button or key.

  To unbind a control entirely, right-click its box; all of its binds will be cleared.


== CALIBRATION ==

  1. Select the device type to calibrate.
  2. Sweep every axis to its full extents, then release to center.
  3. Check "Deadzone", then gently wiggle stick and twist within the deadzone.
  4. Click "Apply" when satisfied or "Clear" to start over.


== CONSOLE COMMANDS ==

X-Wing Revival features a Quake-style console which allows power users to tweak the
game parameters.  Press backtick (tilde) to toggle the console.  If you mess anything
up, quit and delete settings.cfg to restore defaults.

Here are some of the commands currently implemented:

  status: Show the status of various game subsystems, including framerate and ping.
  show: Show all variables.
  set <name> <value>: Change a variable's value.
  exec <file>: Load a config file.
  export <file>: Save a config file.
  g_restart: Apply video settings and restart video.
  joy_refresh: Look for new joysticks that have been connected.
  joy_clone <from> <to>: Define a new joystick category and copy binds to it.
  who: Show list of players connected.
  say <message>: Send chat message.
  echo <text>: Display text in the local console.
  host: Start a new game.
  connect <host>: Join a game by IP/hostname.
  reconnect: Rejoin the IP/hostname last connected to.
  disconnect: Leave the current game.
  quit: Exit to desktop.

When hosting, you can also use the "sv" command to control the server:

  sv show: List game variables.
  sv set <name> <value>: Change a game variable's value.
  sv defaults: Restore all game properties to default settings.
  sv state ++: When a game is in progress, you can use this to end the round early.
  sv netrate <num>: Adjust the network update rate for all clients.  Default: 30
  sv maxfps <num>: Adjust the simulation update rate.  Default: 60
  sv threads <num>: Use extra threads for capital ship collisions.  Default: 0
  sv port <num>: Change the TCP port number (after restart).  Default: 7000
  sv restart: Restart the server.

From a dedicated server console, the sv commands are used without the "sv" keyword.


== COMMAND-LINE OPTIONS ==

You can control X-Wing Revival's behavior with these command-line options:

  -host: Start a new game immediately.
  -connect <host>: Join a game immediately by IP/hostname.
  -name <name>: Set player name.
  -dedicated: Host a dedicated server console instead of playing.
  -set <name> <value>: Change a variable's value.
  -windowed: Start windowed, not fullscreen.
  -safe: Use old fixed-pipeline OpenGL at 640x480 with minimal extensions.
  -screensaver: Load in screensaver mode.  Moving the mouse will quit.


== NETWORKING AND PORT-MAPPING ==

By default, X-Wing Revival servers run on TCP port 7000.  If you wish to host a game
online, you'll need to map this port from your firewall to your PC.  You can override
the server port by changing the "sv_port" variable.

Local games are announced by sending LAN broadcasts on UDP port 7000.  If you have a
software firewall enabled (such as Windows Firewall) and want to play over LAN, make
sure this port is allowed so you can discover local games.


== VIRTUAL REALITY ==

This version of X-Wing Revival has OpenVR (SteamVR) support!  I've only tested this
on the HTC Vive, but it should work on other headsets with SteamVR support, such as
Oculus Rift, Valve Index, etc.  See the Preferences for VR view tweaks.

When playing in VR, there's no radar yet, so pick up your visual scanning!  Messages
won't display by default, but you can show them by pressing return to toggle chat or
holding tab to show scores.


== ABOUT THE SCREENSAVER ==

To use X-Wing Revival as your screensaver, simply copy the RaptorEngine.scr file into
C:\Windows and select "RaptorEngine" in the Screen Saver settings.  Before you can
preview or activate it, you'll need to click "Settings...", browse to your copy of
"X-Wing Revival.exe", and click "OK".

The RaptorEngine screensaver wrapper is only currently available for Windows.  You can
also launch the game with "-screensaver" to watch screensaver mode on any platform.

You can customize the screensaver by creating a text file "screensaver.cfg" with
console commands to execute, such as "sv gametype yavin" or "sv rebel_fighter A/W".
