Intro
The aim of this project is to reverse GTA III for PC by replacing parts of the game one by one such that we have a working game at all times.
How can I try it?
- re3 requires game assets to work, so you must own a copy of GTA III.
- Build re3 or download the latest nightly build (You must be logged in.)
- (Optional) If you want to use optional features like Russian language or menu map, copy the files in /gamefiles folder to your game root folder.
- Move re3.exe to GTA 3 directory and run it.
Building from Source
Before starting you may want to point GTA_III_RE_DIR environment variable to GTA3 root folder, if you want executable to be moved there via post-build script. (premake)
Linux Premake
For Linux using premake, proceed: Building on Linux
Linux Conan
Obtain source code.
git clone https://github.com/GTAmodding/re3.git
cd re3
git submodule init
git submodule update --recursive
Install python and conan, and then run build.
conan export vendor/librw librw/master@
mkdir build
cd build
conan install .. re3/master@ -if build -o re3:audio=openal -o librw:platform=gl3 -o librw:gl3_gfxlib=glfw --build missing -s re3:build_type=RelWithDebInfo -s librw:build_type=RelWithDebInfo
conan build ..
FreeBSD
For FreeBSD using premake, proceed: Building on FreeBSD
Windows
Assuming you have Visual Studio:
- Clone the repo using the argument
--recursive
. - Run one of the
premake-vsXXXX.cmd
variants on root folder. - Open the project via Visual Studio
If you use 64-bit D3D9: We don't ship 64-bit Dx9 SDK. You need to download it from Microsoft if you don't have it(although it should come pre-installed after some Windows version)
If you choose OpenAL on Windows You must read Running OpenAL build on Windows.
ℹ There are various settings at the very bottom of config.h, you may want to take a look there. i.e. FIX_BUGS define fixes the bugs we've come across.
ℹ Did you notice librw? re3 uses completely homebrew RenderWare-replacement rendering engine; librw. librw comes as submodule of re3, but you also can use LIBRW enviorenment variable to specify path to your own librw.
