Tools and technologies used

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
  • apt-get install libopenal-dev

Run these commands in terminal:

Compiling on Windows

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

  • GLEW
  • GLM
  • OpenAL-Soft


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 .

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, Windows 7, Windows 10.

Command Line Params

  • To select specific level to play you can add command line argument -mapname, for example: -mapname SANB.CMP
  • To specify the game data location add argument -gtadata followed by path
