# Intro
|
|
|
|
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.
|
|
|
|
Apparently you can download a binary of the latest version
|
|
[here](https://ci.appveyor.com/api/projects/aap/re3/artifacts/bin%2FReleaseCI%2Fre3.dll?branch=master).
|
|
|
|
# Strategy
|
|
|
|
A good approach is to start at the fringes of the code base,
|
|
i.e. classes that don't depend on code that we don't have reversed yet.
|
|
If a function uses only few unreversed functions that would be inconvenient
|
|
to reverse at the time, calling the original functions is acceptable.
|
|
|
|
# Progress
|
|
|
|
This is a list of some things that have been reversed to some non-trivial extent.
|
|
Not everything is listed, check the code.
|
|
|
|
```

CPool
|
|
CTxdStore
|
|
CVector
|
|
CVector2D
|
|
CMatrix
|

CCullZones

CTheZones

# Low hanging fruit
|
|
|
|
There are a couple of things that have been reversed for other projects
|
|
already that could probably be put into this project without too much effort.
|
|
Again, the list is not complete:
|
|
|
|
* Animation (https://github.com/aap/iii_anim)
|
|
* File Loader (https://github.com/aap/librwgta/tree/master/tools/IIItest)
|
|
* ...

# Coding style
|
|
|
|
I started writing in [Plan 9 style](http://man.cat-v.org/plan_9/6/style),
|
|
but realize that this is not the most popular style, so I'm willing to compromise.
|
|
Try not to deviate too much so the code will look similar across the whole project.
|
|
|
|
To give examples, these two styles (or anything in between) are fine:
|
|
|
|
```
|
|
type
|
|
functionname(args)
|
|
{
|
|
if(a == b){
|
|
s1;
|
|
s2;
|
|
}
|
|
if(x != y)
|
|
s3;
|
|
}
|
|
|
|
type functionname(args)
|
|
{
|
|
if (a == b) {
|
|
s1;
|
|
s2;
|
|
}
|
|
if (x != y)
|
|
s3;
|
|
}
|
|
```
|
|
|
|
This one (or anything more extreme) is heavily discouraged:
|
|
|
|
```
|
|
type functionname ( args )
|
|
{
|
|
if ( a == b )
|
|
{
|
|
s1;
|
|
s2;
|
|
}
|
|
if ( x != y )
|
|
{
|
|
s3;
|
|
}
|
|
}
|
|
```
|
|
|
|
Indentation is done with TABS.
