![]() ![]() This is the quake2 project in the workspace. Kernel calling modules and performing client/server network communications. This approach would have been valid for Quake 2 because the engine is not fundamentally different but it was easier to spot the improvements by dividing it by the three main project types: Project type When I read Quake 1 source code I divided it in three part: Network, Prediction and Rendition. Once built don't forget to place the libpng and zlib dlls in the same folder as quake2.exe. Make sure your select the Debug DLL configuration. Now if you are using my version: I added the engine capability to output PNG screenshots, so you also need to build libpng and libz (it is in a subdirectory).If you are using the quake2 release from id software it should fix the issue. Make sure you are linking all 5 projects with the same runtime library by right clicking on each project -> properties -> C/C++: Check that "runtime library" = Multi-threaded Debug DLL (with configuration "Debug",.If the DLL is not exactly what it was expecting or if the DLL dependencies cannot be resolved it will fail silently instead of displaying the error message. Quake2 kernel loads its two dlls using win32 API: LoadLibrary. Note : If after compiling you run into the error: "Couldn't fall back to software refresh!" it means the renderer DLL failed to load properly, this is easy to fix: Software erosion: It seems that what happened to Quake codebase has started to happen with Quake 2: You cannot open the workspace Installed Direct3D SDK and Microsoft SDK (for MFC) and the thing compiled fine. Note 2: Building failed at first because of DirectX header missing:įatal error C1083: Cannot open include file: 'dsound.h': No such file or directory Note : "ctf" and "game" projects overwrite each other, more about this later. Here is a summary of the building targets: Projects This is because Quake2 is designed to be modular (I will detail this later). The first striking thing is that the Visual Studio 6 workspace is not made of one project but five. The project can be opened with Visual Studio Express 2008, also available for free on Microsoft website. The source code is available for free on id software ftp website.

Publish my raw ASCII notes in the future (I am thinking of Quake3 and Doom3 source), let me know what you think. In the end I am not sure it was worth it and I may just I got a bit carried away with the "cleanup" process since there is more thanĤ0MB of videos,screenshots and drawings in this article. Marking the gaming industry's departure from software/8bits color system to hardware/24bits color system that occured around 1997.įor all those reasons, I highly recommend anyone that appreciate programming to dive into it.Īs usual I took numerous notes, cleaned them up and publish them as it may Popular (in term of licensing) 3D engine of all time. ![]() In a lot of regards Quake II is a shining piece of software history since it is the most The way modularity was achieved even though the C programming language doesn't feature polymorphism was especially Quake World and QuakeGL into one beautiful code architecture. It was a wonderful learning experience since one major improvement in idTech3 engine was to unify Quake 1, I spent about a month in my spare time reading the source code of Quake II. It's important to run the demo twice for more accurate results.Ĭonsole showing timedemo and demomap usage including benchmark results in FPS.September 16th, 2011 Quake 2 Source Code Review 1/4 Once in the console type timedemo 1 and then demomap kos1.dm2 in order to play the demo. After the defaults have been loaded I select the resolution and bit-depth I want to benchmark.Īfter selecting the resolution go back to the menu and press the escape-button. After starting the game I go to the video options and choose 'Apply defaults'. More or less the effect of the Nightmare Skill from Doom.Ĭlean install with default settings. You could kill every enemy in a room and advance, but once returned the enemies would be alive again. The game also featured a difficulty setting in which enemies appeared 'on the fly'. Especially regarding blood and the GHOUL damage model which allowed the player to dismember body parts from killed enemies. Soldier of Fortune was criticized for being violent. ![]()
