Compiling on Linux

At the moment, makefile configured so project will build with clang compiler.

Before build project make sure to install dependencies: * apt install libglew-dev libglm-dev libgl1-mesa-dev xorg-dev clang

Run these commands in terminal: git clone --recurse-submodules https://github.com/codenamecpp/carnage3d cd carnage3d * make

Compiling on Windows

You will need Visual Studio 2015 Community Edition to build project. Before compile, add system environment variable SDKDIR with path where all the dependencies lives. These dependencies are: GLEW GLM

Configure

Game needs to be configured before launch, there is example config document in gamedata/config/sys_config.json.default - it must be copy-pasted to same directory but withoud ".default" suffix: gamedata/config/sys_config.json .

Most important param there is gta_gamedata_location - it is location of GTA1 gamedata resources.

How To Run

Original GTA1 game resources required in order to play (Full or DEMO). Demo version still available for download https://www.rockstargames.com/gta/extras/demos.html .

It is possible to download and play demo version of the game easily just typing a few commands in console: make get_demoversion make run_demoversion

Note that game must be compiled and configured before this step as described above.

Tested on Ubuntu Linux and Windows 7 64bits.

Command Line Params

To select specific level to play you can add command line argument -mapname, for example: -mapname SANB.CMP.

Controls

It is similar to original: Arrow keys to walk/drive in directions Space to slide on car Enter to enter or exit car Tab to enable or disable car emergency lights (if it present) * Z, X to change current weapon and Ctrl to shoot

When in "Free Look" camera mode, moving with W, S, A, D keys.

In addition there is support of xbox-compatible gamepads. To enable it or change default key bindings create config file gamedata/config/inputs.json (copy-paste template inputs.json.default) and modify it as you wish.
