Oculus Rift support for Jedi Academy

This project provides new binaries for Jedi Academy with added Oculus Rift support (for Windows and Linux).

The original game and resources are needed to start the game.

This Oculus Rift support implementation is designed for first person game play. It is possible to switch to 3rd-person view, but the best (and motion sickness free) experience is in first person mode.

Main Menu -> Setup -> More Video

  • set Shadows to Simple
  • disable Dynamic Glow
  • disable Light Fares

Play the game

Binary:

There are binaries for Linux and Windows checked into the Github repository, so if you want to just play the Oculus Rift version, download the binary files and start playing right away.

https://github.com/xLAva/JediAcademyLinux/tree/HmdSupportDK2/binary/win32

https://github.com/xLAva/JediAcademyLinux/tree/HmdSupportDK2/binary/linux_i386

Copy all the files from the Windows or Linux platform folder into the following directory of your "Jedi Knight III: Jedi Academy" installation:

[Jedi Academy Install Folder]/GameData/

Original Patch:

For those not having the Steam version: you'll need the 1.01 update from here http://help.starwars.com/articles/en_US/FAQ/Where-do-I-find-the-latest-patch-for-Jedi-Knight-Jedi-Academy?section=Star-Wars#patch

Additional Asset File (optional):

The additional asset file just contains a new default config with the gamepad already setup (including Head-Mounted-Device recenter using the start button). Also a small translation string was added for the resolution selection. The game runs fine without this asset file.

If you want to use it, download the additional asset file and place it into the following folder of your "Jedi Knight III: Jedi Academy" installation:

https://github.com/xLAva/JediAcademyLinux/tree/HmdSupportDK2/binary/base/assets4.pk3 ->

[Jedi Academy Install Folder]/GameData/base/

Platform Specific:

The version was tested on Ubuntu 14.04 and Windows 7.

Windows:

The Oculus Runtime 1.3 is needed to run the game in VR mode.

Ubuntu:

The Oculus Runtime 0.5 is needed to run the game in VR mode.

The universe repository has to be activated (Software & Updates)

Needed libraries on Ubuntu 14.04 32bit: sudo apt-get install libsdl2-2.0-0 libopenal1

Needed libraries on Ubuntu 14.04 64bit: sudo apt-get install libsdl2-2.0-0:i386 libopenal1:i386 libgl1-mesa-glx:i386

Be sure to mark "jasphmd" as executable and start the game with it.

Build the game

If you want to build the code yourself, just follow the instructions in Build.md.

More information

For the DK2 support I had to use the OculusSDK. The OpenHMD library just doesn't support all the features. It is still possible to build the game with OpenHMD support. Just follow the instructions in the Build.md file. The OculusSDK library is loaded during runtime and the game also works fine without the library.

This version can also be played without any Head Mounted Device. All HMD tweaks will be disabled and the game should behave like the original version.

Before I started this project, I had a look at the rift support implementation from LeeN (mtbs3d forum). This helped me to get started. Thx LeeN.
