Status

Fortunetly broken after Half-Life 25th anniversary update (because binaries do not export dynamic symbols now). I'm not going to fix this because:

1. I hope hl1 will get some activity again, so I don't want to flood servers with cheaters.
2. I don't see much fun in dealing with byte patterns and offsets.

HlHaxLib

HlHaxLib is a linux hack for games based on goldsource engine so this can work for many games like half-life 1, counter-strike 1.6, etc. For features list see src/funcs.

Startup

1. Clone this repo.

2. Download SDK:

    mkdir sdk
    git clone https://github.com/ValveSoftware/halflife.git sdk/halflife-master

3. Prepare build folder:

    mkdir build
    cd build
    cmake ..

4. Actually build:

    make

5. Start hl1 (preferably from terminal).

6. Inject hax (be sure you are in build folder):

    ./injector.sh load

   P.S. injector runs make every time, so don't worry about modifying sources.

7. Make sure hax loaded fine.

   Check in-game console and find line "hlhax loaded". Also you can try to start typing hx_, cv_ or +hx_ and a completion list should appear.

Credits

Many thanks to all game hacking communities, this is a really big scene. Mostly it's a site www.unknowncheats.me, but also I've seen some archived forum pages of www.gamedeception.net.

Also thanks to russian forum pvpru.com. A long time ago there was many good persons who write stuff and share code/instructions about counter-strike 1.6 .

Unknown Russian site with a lot of useful information about hacks in cs 1.6: http://troll-homepage.narod.ru/

Special thanks to shelru for method of injecting library into process using debugger, which idea I took from extramirror version for linux.

Somewhere in the code I also inserted urls to original sources, but I'm sure that's not all.
