This design decision was discussed at length in John Carmack's. This allows among other things to record (journalize) each inputs in order to recreate bugs. Every single input (keyboard, win32 message, mouse, UDP socket) is converted into an event_t and placed in a centralized event queue ( sysEvent_t eventQue).Two important things to understand the design: Then look how the inputs flows towards the outputs in a whitebox fashion with the 6 modules ( quake3.exe, renderer.lib, bot.lib, game, cgame and q3_ui) interacting as follow:
#Quake arena software#
Open /code/quake3.xcworkspace and it builds in one click !!Ī convenient way to understand an architecture is to first look at the software as a black box receiving input (upper left arrows) and generating output (bottom arrows): To use the parameters "+set vm_game 0 +set vm_cgame 0 +set vm_ui 0" in order to use the dylib virtual machines. You will need the Quake III Arena baseq3 (not the demo version) and be sure
#Quake arena mac os x#
We have the Trinity River in Dallas, and so it was just like "Trinity Engine," the next step.Įdit ( J) : Jeremiah Sypult contacted me after publication of this article: He "unrotted" the Mac OS X build with an XCode 4.0 project for Quake3. Michael Abrash suggested we just take Intel's tack of naming your next project after a river near I was starting on new rendering technologies and everything, everybody was just calling it "the next engine"
John : I was never really certain how this got as confusing as it did to everybody. It was named after "Trinity River in Dallas": John : I've got a couple of engine things that I'm working on, as far as research.įS : So is one of those things Trinity? I think there's been a little confusion about "Trinity." Since idTech4 was called "Neo" I assumed it was from the "Matrix" franchise.but id Software stated in interview with that Trivia : idTech3 working title was "Trinity". Some of the projects are never used ( splines and ui).Ī table is better to summarize what project is contributing to which module: Projects (especially game, cgame and q3_ui : the virtual machines projects). Not all of them are used depending if the build is DEBUG or RELEASE The first striking thing is that the Visual Studio workspace is not made of one project but eight.

In the end I used Visual Studio 2010 Professional on Windows 8: Upon installation of Visual Studio 2010 Productivity Power Tools
#Quake arena code#
When it comes to comprehend a huge codebase I prefer to use XCode: SpotLight speed, Command-click to find definition and strings highlight make the tool more powerful than Visual Studio.īut opening Quake III project showed that code rotting is not always about the code but also about the tools: XCode 4.0 is unable to open the Quake III XCode 2.0 projects. Since the venerable was recently decommissioned the code can be found on I hope it will save time to some people but also encourage others to read more code and become better engineers.
Part 3 : New Network model based on snapshots.Part 2 : New dualcore renderer with material based shaders (built over OpenGL Fixed Pipeline).The key points can be summarized as follow: The engine is mostly an evolution of idTech2 but there are some interesting novelties. IdTech3 the 3D engine that powers Quake III and Quake Live. After Doom, Doom Iphone, Quake1, Quake2, Wolfenstein iPhone and Doom3 I decided to read the last codebase I did not review yet: Since I had one week before my next contract I decided to finish my "cycle of id".
