## Intro
2019-05-15 22:52:37 +08:00
The aim of this project is to reverse GTA III for PC by replacing
parts of the game [one by one ](https://en.wikipedia.org/wiki/Ship_of_Theseus )
such that we have a working game at all times.

## How can I try it?
2019-06-13 17:12:42 +08:00
2020-09-25 19:56:15 +08:00
- re3 requires game assets to work, so you **must** own [a copy of GTA III ](https://store.steampowered.com/app/12100/Grand_Theft_Auto_III/ ).
2019-11-07 06:53:54 +08:00
- Build re3 or download it from one of the above links (Debug or Release).
2020-04-17 23:30:59 +08:00
- (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.

## Preparing the environment for building
2020-05-12 06:24:54 +08:00
2020-09-30 18:54:57 +08:00
- Clone the repo using the argument `--recursive` .
2020-05-12 06:24:54 +08:00
- Point GTA_III_RE_DIR environment variable to GTA3 root folder.
- Run premake
- On Windows: one of the `premake-vsXXXX.cmd` variants on root folder
- On Linux: proceed to [Building on Linux ](https://github.com/GTAmodding/re3/wiki/Building-on-Linux ).
- There are various settings at the very bottom of [config.h ](https://github.com/GTAmodding/re3/tree/master/src/core/config.h ), you may want to take a look there. i.e. FIX_BUGS define fixes the bugs we've come across.
2020-07-22 20:20:52 +08:00
- **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)
2020-07-30 00:25:27 +08:00
> :information_source: **If you choose OpenAL on Windows** You must read [Running OpenAL build on Windows](https://github.com/GTAmodding/re3/wiki/Running-OpenAL-build-on-Windows).
2019-05-23 05:12:07 +08:00
2020-07-22 20:20:52 +08:00
> :information_source: **Did you notice librw?** re3 uses completely homebrew RenderWare-replacement rendering engine; [librw](https://github.com/aap/librw/). librw comes as submodule of re3, but you also can use LIBRW enviorenment variable to specify path to your own librw.

### Unreversed / incomplete classes (at least the ones we know)
2020-04-07 22:48:49 +08:00
The following classes have only unused or practically unused code left:
```
2020-11-24 00:59:50 +08:00
CMemoryHeap - only on PS2
NameGrid.cpp - only on mobile (a player name grid, either a very early player name code ala GTA1 or a multiplayer leftover)
PedDebug.cpp - only on mobile (debug code)
HandlingMgr.cpp - debug functions from mobile
CVehicle::ProcessBikeWheel - early bike code (only on mobile)
CAutomobile::DebugCode - debug function from mobile
CBoat::DebugCode - debug function from mobile
CBoat::ModifyHandlingValue - debug function from mobile
CBoat::DisplayHandlingData - debug function from mobile
TexturePools - only on PC (slight RW modification that we don't actually need)
