OpenXRay

OpenXRay is an improved version of the X-Ray Engine, the game engine used in the world-famous S.T.A.L.K.E.R. game series by GSC Game World.

Goals

1. Make it a drop-in replacement for original engine.
   1. Aim at 99% compatibility and same behaviour, where possible.
   2. Compile engine into a single executable file that you can just drop into bin folder. (see #210)
2. Support all three games in the series: SOC/CS/COP. (see Supported games below)
3. Fix original X-Ray Engine bugs that were polluting S.T.A.L.K.E.R. series.
4. Introduce a solid platform for modmakers:
   1. Add frame/render graph for those who want to add new graphics features.
   2. Improve performance via refactoring the code, parallelizing the engine, making it multithreaded.
   3. Add new scripting, development and debugging features.
   4. New game SDK with new features.
5. Clean up engine code, make it easily portable to new platforms, minimize platform-specific code.
6. Enhance player’s experience with new graphics, gameplay and other features that can be enabled optionally. (by default, we stay close to vanilla)

Main differences from original X-Ray are:

• Support for 64-bit.
• Support for ARM, ARM64, E2K (Elbrus 2000), PPC64LE.
• Works on Linux, macOS, OSL (Elbrus OS).
• New OpenGL renderer. (currently, requires OpenGL 4.1 minimum, lowering to at least OpenGL 3.3 is planned)
• Improved performance, better FPS.
• Original bugs fixes.
• New features for modmakers.
• Gamepad support. (not yet finished, but you can try already, see #943)
• New game SDK being currently developed. (see Game Editor)

You can see the detailed differences table here

Supported games

OpenXRay is based on X-Ray 1.6.02, used in S.T.A.L.K.E.R.: Call of Pripyat, so initially it supported only this game.
Currently, we are working on support for all three games in the series.

Call of Pripyat	Clear Sky	Shadow of Chernobyl
Yes	Release candidate (see #382). Minor bugs possible, but game is stable finishable.	Not supported yet (see #392)

Contributing

All contributions are more than welcomed. There are several ways how you can contribute:

Community

Play and enjoy the game, file an Issue when you encounter any bugs, or you have an enhancement request.

Join us on our Discord, subscribe to our YouTube channel, join our VK group, leave a comment, put a like and communicate there!
Also you can put a star on this repository :)

Development

Join our efforts in making our beloved game better, send pull requests, participate in discussions and code reviews!

It is a place to share ideas on what to implement, gather people that want to work on the engine, and work on the source code. However, the following things should be taken into consideration:

• We want to keep the game close to the vanilla, so if you want to introduce new gameplay features, make sure it is optional, and doesn’t break compatibility with original game resources (i.e. everything in gamedata folder and .db*/.xdb archives). You also may want to add non-gameplay features, fix bugs, or improve engine performance and code quality.
• Major changes should be discussed before implementation.

Take a look at our Issues page:

• See issues labeled as good first issue to get familiar with the engine code in practice.
• You may also want to look at issues labeled as help wanted. Some of them are difficult ones, though.

The dev branch is the default and base branch for the project. It is used for development, and all pull requests should go there. But be aware that this branch sometimes may be broken, and we can only rarely do force pushes to this branch.

Be advised that this is a community project not sanctioned by GSC Game World in any way – and they remain the copyright holders of all the original source code and S.T.A.L.K.E.R. franchise. However, they know about many community projects, including this, and support the S.T.A.L.K.E.R. community efforts to make the game better.
