Jake2 README

Screenshots

Jake2 is a port of the GPL'd Quake2 engine from id Software to Java. Jake2 is distributed under the terms of the GPL (see LICENSE).

The port is implemented in Java, but some native libraries (LWJGL) are used for the visual rendering, input processing and audio playback (OpenAL) functionality.

Jake2 is still under development. Feel free to send bug report if you find one.

Currently, Jake2 supports every Java supported platform.

Requirements:

• jdk version 11 to build and run Jake2

Please note that there is an issue with more recent java versions (17) on linux with lwjgl natives.

What is Cake? Important note about client side code

Jake2 client in its vanilla form is archived in jake2-legacy branch and will not be maintained. Even though one of the core ideas of this project was to reuse and improve (rather than reimplement from scratch) - the client side code was particularly hard to maintain and develop. Firstly, because it is written on top of the unmaintained and obsolete second LWJGL version, which is incompatible with the current LWJGL version. Secondly, jake2 rendering is implemented in OpenGL immediate mode and had to be rewritten on a modern shader pipeline anyway. And lastly, there is a libGDX framework that can provide a lot of useful functionality, and ditch a lot of code (yes, Menu.java, I am looking at you)

The client and fullgame modules are excluded from the build. The new cake module is introduced for the client side part (WIP).

TODO: update readme

Installation and running

from binary distribution:

• unzip the distribution(jake2-some_version.zip)
• go to bin folder
• run ./fullgame (or fullgame.bat on windows)

build from source:

• run gradle run to build from source and run jake2
• run gradle distZip to build the distribution

If you don't have a gradle distribution you can use gradle wrapper, like ./gradlew run.

If you run jake from an IDE:

1. add dependency to gradle installDist task before launch
2. add -Djava.library.path VM option to point to the location of native libs (they are copied to the fullgame/build/install/fullgame after the task mentioned above)

Installation of Quake2 data:

Jake can autodetect steam installation. If it doesn't (when you have a non-steam version or when you install it to a custom location) pass basedir parameter to the game

+set basedir "/home/demoth/.local/share/Steam/steamapps/common/Quake 2"

If you want to have the latest experimental features you can grab the latest Jake2 sources from GIT.

Compatibility

Jake2 is not compatible with the mods that have custom logic (game.dll).

Jake2 is network compatible with other clients, like Yamagi, Q2pro etc.

Jake2 is compatible with all map/models/sounds/textures as id Quake 2.

Goals of the project

While Jake2 is a hobby project it is important to keep at least high level goals in mind:

1. Maintain project runnable on modern machines and operating systems
2. Bring the codebase up to contemporary expectations.
3. Expand features of jake2 to bring more fun playing/modding it

At the moment of writing the goal N1 is achieved and goad N2 is in progress.

Roadmap

With accordance to the goals we can put a list of more concrete steps:

• gather game state in classes. at the moment state of the process is scattered across many static fields.
• code cleanup - move to modern libraries (filesystem, network, logging)
• file formats - support modern file formats (zip, image, audio, video, models?)
• support "brother projets" content: q2 mission packs, q1? q3? hl?
• replace q2 ui code (not 3d) with a library (i.e. nifty-gui)

Crazy ideas area (proceed with caution):

• add script support: graalvm support many scripting jvm languages, with little overhead. implement monster, items behavior with scripts
• change 3d rendering code to something more recent (like yq2 gl3, q2xp?...)
• implement mmo-like replayable campaign for q2: npc, quests, character progression, item & monster randomization, trading
• jake2 game engine suit (unreal like): full set of tools to support game development and creation of new games. 3d editor, entitity editor, scripting, and so on
• procedural map generation
• utilize kotlin multiplatform support and create jake2 clients for various platforms (desktop, web, android, ios)

3rd party components
