JEDI FIGHTER is a mod inspired by classic fighting games (SNK's Last Blade I & II, Capcom's Street Fighter II) for Raven Software's latest Star Wars first-person shooter, Star Wars: Jedi Knight: Jedi Academy. Embroiled in a battle between GOOD versus EVIL, you are a fearsome lightsaber fighter forced to use your training to take on legendary warriors and, perhaps, decide the FATE OF THE GALAXY...

GAMEPLAY

You fight from a side view perspective in one-on-one matches against other humans online or against really terrible bots (AI players won't make good opponents until beta 3). A cinematic camera keeps an eye on the action.

Fight your opponent by using any of 10 characters across 5 arenas, where each character harnesses the force and saber combat in a unique way, while the arenas showcase various settings from the Star Wars universe.

CONTROLS

Gamepads are supported and how it was meant to be played!

There are 3 basic attacks, plus block and the 4 directions, which you will use to perform combos:
1) up
2) down
3) left
4) right
5) horizontal attack
6) vertical attack
7) alternate attack (kicks or force powers)
8) block

Patience, young Skywalker. Performing combos is not easy, and will take some practice to get a feel for the input system. The on-screen help in beta 2 shows the required buttons which must be pressed in sequence (but not simultaneously) in order to make a special move happen.

INSTALLATION

There are 2 prerequisites to installing JEDI FIGHTER.

  1. Install Star Wars: Jedi Knight: Jedi Academy. You can purchase it on STEAM here for $9.99 or less.
  2. Install the OpenJK engine. Download it here. Once you have it downloaded, extract the .zip file into your Jedi Academy\Gamedata directory. Confirm it's actual location before proceeding (for most people it would be C:\Program Files (x86)\SteamLibrary\SteamApps\common\Jedi Academy\GameData\ OR C:\Program Files (x86)\LucasArts\Star Wars Jedi Knight Jedi Academy\gamedata\).

Now you should install JEDI FIGHTER itself by following these 3 simple steps:

  1. Download JEDI FIGHTER beta 2 from here (which you already did!):
  2. Unzip it to your Jedi Academy\Gamedata directory (e.g. C:\Program Files (x86)\SteamLibrary\SteamApps\common\Jedi Academy\GameData\ OR C:\Program Files (x86)\LucasArts\Star Wars Jedi Knight Jedi Academy\gamedata\)
  3. Right click on SETUP.BAT in the Jedi Academy\gamedata\jedifighter\ directory, and choose "Run as Administrator". This makes sure OpenJK will launch JEDI FIGHTER correctly. (It sets up a symbolic link to your Windows user "\Documents\My Games\OpenJK\OpenJK\jedifighter" directory needed by OpenJK to the
    jedifighter installation directory. Contact me with questions or suggestions on this.)


HOW TO PLAY \ START A SERVER

Starting the JEDI FIGHTER CLIENT is pretty straightforward... Run the JF_CLIENT_OJK.BAT file in your Jedi Academy\gamedata\jedifighter directory OR do it from the commandline (ONLY IF YOU KNOW WHAT YOU ARE DOING):

openjk.x86 +set sv_pure 1 +set fs_basepath "D:/games/LucasArts/Star Wars Jedi Knight Jedi Academy/GameData" +set fs_game jedifighter +set g_gametype 5

That's it.

When you first run JEDI FIGHTER, you should go into the CONTROLS menu to bind your controls and the SETUP menu to set your video options. All kinds of crazy resolutions are supported, but if you want to customize it, start typing your own width and height! You should set your video options to the highest
resolution your display can support and enjoy modern PCs playing 15 year old games at ridiculous speeds.

To join a game, go to the main menu and Play -> Join a Game. Make sure the filtering is set to "Internet" (or "Local" for LAN games), "All", and "Jedi Fighter". Get a new server list. Click on the server and then click Join! (The mapname should start with jf_ or jf2_ if it's a Jedi Fighter server, otherwise you
might end up trying to connect to an OJP Enhanced server).

Starting the JEDI FIGHTER LISTEN SERVER is simple. Run the JF_CLIENT_OJK.BAT file and then go to the main menu and choose Play -> Create a Game.

Starting the JEDI FIGHTER DEDICATED SERVER is also simple. First edit jedifighter\server.cfg and AT LEAST modify the RCON password. Then run the JF_DED_OJK.BAT file. People will need to vote for a particular map or cycling to the next map.

MISCELLANEOUS

An SDK and help documentation for people extending the base content in JEDI FIGHTER will be made available shortly. For now, please feel free to extract all of the .pk3 files and poke around in the files. Of particular interest will be the jedifighter\fighters\ directory and it's subdirectories, and the maps\mp
directory, which contains all the .map source files. If you want to make a map, you'll notice that there are new spawn entities, and that the fighting plane needs to be axis aligned in a particular way. You'll see this in all of the .map files and should stick to it or you are on your own. Documentation for most of
this will be available soon, but some of it should be intuitive.

If you have complaints, comments, or suggestions, feel free to send them to me at adnan.f.zafar @ gmail.com.

Finally, thanks for trying JEDI FIGHTER beta 2!

Now then...

JEDI FIGHTER beta 3 is in development and will have improved AI!

Tentative release in April! No more randomly jumping bots! Yay!


What is the AI going to be and why?

The main objectives with the AI are to:

  1. create a compelling opponent that isn't entirely predictable,
  2. utilize the least amount of man hours in tuning the AI if the move set is modified,
  3. and polish my skills in machine learning.

The general approach for the AI is going to be using one multi-layer perceptron (MLP, a type of neural network) per fighter. Basically, an MLP takes inputs, processes them, and produces outputs based on how it has been trained to respond to inputs. The outputs will be a set of numbers from 0 to 1, where there will be one number per move or block. The number with the highest value will correspond to the move that gets chosen. Since each fighter has different moves, there will be one MLP per fighter.

I chose MLPs because:

  1. they can be trained to be a little unpredictable (more on this later)
  2. if training data could be automatically generated, then they could be retrained with little manual effort
  3. they are a type of machine learning
  4. and this is a practical implementation people have tried before successfully

For each major system in Jedi Fighter, I try come up with a few concepts and will choose between them based on feasibility, simplicity, and maintainability. This is usually done on paper OR through the implementation of minimum viable products (MVPs) where it's practical in my free time.

The AI is going to get a few MVPs to experiment with the key components of training and decision making. I'll be sharing updates on those MVPs as time allows.

Show me the video!

Okay!

Neural networks use training data to optimize the network into generating the desired output for a range of input conditions.

This video shows the bots executing their moves randomly and sampling inputs (fighter and opponent health, position, and velocity) right before the move and immediately afterwards. The change in health (and other parameters) will be used to indicate the effectiveness of the move. This will be done many thousands of times per character to create a reasonably sized dataset to train the AI.

Three things evident from this experiment:

  1. Darth Vader is overpowered (has a few moves, where a high percentage of them are devastating) so things are inherently unbalanced
  2. Because Darth is overpowered and kept winning, he got many more training samples generated than the others, which means I need to ensure fairness in training set generation (i.e. equal number of samples used to train each fighter)
  3. Fighters occasionally get stuck on each other during spawning, so that will be addressed.

Stay tuned and download JEDI FIGHTER beta 2 while you wait!

JEDI FIGHTER beta 3 is coming in April!

Find out more and follow the JEDI FIGHTER beta 3 AI progress on this forum thread. I'll post here with more information as soon as progress is made!

HI, is this something you're seeing on the Steam version of Jedi Academy? If so, try exiting JA, and starting it over again.

It sounds like you don't have it installed correctly. Please go back and follow the install instructions carefully. If you still have an issue, please start a thread in the "help" section of the forums.

Hi temmie1,

One other person reported a similar issue the first time they tried it with Steam. They said the second time they tried it that it worked by itself.

First, let's make sure you have it properly installed.

(For the following steps, I'm going to refer to your Jedi Academy installation directory. If you don't know where that is, get out of big picture mode, right click on Jedi Academy in the steam library view, go to properties, click on the "Local Files" tab, and then click on the "BROWSE LOCAL FILES" button. This will open up explorer in your Jedi Academy directory.)

1) Unzip the OpenJK engine (openjk-2016-01-11-4ad9ed4a-windows.1.zip from Moddb.com) to the steam Jedi Academy gamedata directory. It should be something like C:\Program Files (x86)\SteamLibrary\steamapps\common\Jedi Academy\GameData.

2) Unzip Jedi Fighter beta 2 (jedifighter_beta2.zip from Moddb.com) to the same directory.

3) Go into the jedifighter directory within the Jedi Academy\gamedata directory and right click on SETUP.BAT and choose "Run as Administrator".

4) Run jedifighter by double clicking on JF_CLIENT_OJK.bat in the Jedi Academy\gamedata\jedifighter directory.

If you do all of this and still have the problem, then exit Jedi Academy and try it a second time. If it still doesn't work, let me know.

The batch file does work in the background to set up a symbolic link in your filesystem so OpenJK will work with your jedi fighter directory. It doesn't make icons on your desktop or start menu if that's what you're expecting.

Now that you ran SETUP.bat, you can start the game by running JF_CLIENT_OJK.bat.

If you need further help, post in the forum and I'll help you out.
