Stunt Car Racer

Background

A fork of a fork... This is a fork of fluffyfreak/stuntcarracer, which is a fork of stuntcarremake from sourceforge.

Long story short, at some point the original Amiga source code for Stunt Car Racer was released, and Daniel Vernon and Andrew Copland translated it to C++ and made a Windows version of it.

That was not the entire original game - you could choose a track and race that against a computer player, but it did not include the original tournament mode or player-versus-player options. Still for fans of the original game, this was awesome!!

Not having a Windows PC at hand, I could only play this through something like WINE. It was not a great experience. So I set up to make a browser version of it - modern browsers are great at 3D graphics, sound, and input. And with the help of projects like Emscripten, it's relatively easy to compile C++ into JavaScript and WebAssembly and translate OpenGL to WebGL etc.

So I started off and implemented the Windows APIs used by the game code in a way that Emscripten can use - the DirectX API would use OpenGL, etc.

It turns out that a similar project was already underway, which I was unaware of: ptitSeb/stuntcarremake. This project uses a separate DirectX emulation library, and as such is a much cleaner approach. I am not worthy!

However, I'll continue this fork nevertheless! My mission is to create a version that is more "web-native" and mobile-friendly, and which will end up being a complete version of the original game. For example, this version includes a tournament system like in the original game, and... two-player mode! (Really, try this out!!)

Try it Out!

Building

Install Emscripten and run

$ ./build-and-serve.sh

...and point a browser to http://localhost:8000/source.html.

If you want to run in two-player mode, you need to run the simple Sinatra-based web service in the signaling folder. Install Ruby, then run:

$ bundle install
$ bundle exec rackup --host 0.0.0.0 --port 8080

Then specify http://localhost:8080 (or whatever local IP name your computer is exposed as on the local network) as the Signaling Server on the Two Players join screen.

More on the Origin of the C++ Code

From the original SourceForge page:

About. This is a partial Windows conversion of the classic computer game Stunt Car Racer.
The game is based on the original Commodore Amiga version. It is written in C/C++ and utilises DirectX/Direct3D.

The game uses the original Amiga track data, sound samples and algorithms for the car physics (all of which were copyright Geoff Crammond / MicroStyle / MicroProse and now copyright the current owners which are believed to be Infogrames or Interactive Game Group).
