Pair programming really needs to be experienced to be fully appreciated. Just a few years ago, I loved my single office and I was completely against the idea of spending all my time programming with somebody else sitting at the same computer. Today I advocated using pair programming at work and I gladly gave up my office to work in a pair-programming lab alongside the whole team. Funny how things change. ...
E3 is just around the corner, so we can expect to finally get the official announcements of Microsoft’s next-generation console, and maybe even Sony’s. That will mark the official transition into the next generation. And this is not just another console generation transition. This time it’s bigger. Much bigger. ...
The great majority of the literature on warfare concentrates on topics such as formations, maneuvers, equipment, and training. What they often leave out is the importance of the supply lines. The most cunningly devised plan will be worthless in the long term if your supply lines fail. The same can be said for large-scale C++ development. Most of the books and articles out there deal with class hierarchies, object-oriented design, and mind-bending template tricks. However, when it comes down to it, a solid physical structure and good code layout will go a long way towards making all programmers productive. When the milestones near and the pressure piles on, a badly structured C++ codebase is likely to be as fatal as the cold, Russian winter was to Napoleon’s army. ...
This year’s GDC, for a change of pace, was held in San Francisco. It was also the last GDC dealing mostly with the current generation of consoles. Yet again, GDC managed to live up to all expectations. I walked away totally exhausted, but at the same time energized and inspired and full of new ideas. ...
After reading the first two parts of this article, you should have enough information to strike boldly and apply test-driven development to your projects. At first you’re likely to find that the road is somewhat rough and bumpy, though. How do you break up this module into something testable? How can you prevent your tests from becoming a burden to maintain? What exactly should you test? ...
It’s that time of the year again: days are getting longer, the weather is slowly getting warmer, and a hint of change is in the air. That can only mean one thing: the Game Developers Conference is approaching again! This article will help you navigate your way around GDC more successfully and help you get the most out of this year’s conference. ...
Part 1 of this article provided just a glimpse of what was behind the looking glass. Now we’re ready to dive in all the way and look at how we can apply test-driven development to games. Be warned: the looking glass is very much one-way only. After you try this, you might become test infected and may never be able to go back and write code the way you’ve done up until now. ...
If you’re a typical game developer, you probably don’t write any tests for the code you create. So how would you feel about not just writing tests, but creating them before the code they are testing? What if I told you those tests don’t even verify that the code you write is correct? “It’s madness,” you might say; “it’s all backwards!” Not really. It all makes sense in its own way. Follow me through the looking glass and I’ll show you the wonderful upside-down world of test-driven development and how we can apply it to games. ...
There is no doubt that Xoreax’s Incredibuild will speed up most full builds of C++ projects using Microsoft Visual C++ to varying degrees. I’m not going to argue that. But is using Incredibuild in your project really a good idea? ...
One aspect of the scientific process is publishing detailed experiment descriptions and results so that they can be independently verified by other scientists. That’s exactly what I decided to do after reading Kyle Wilson’s surprising results in his article “Experiments with Includes.” ...
I often get email from people looking to get their first job in the game industry asking me for advice. What are companies looking for in candidates for entry-level programming positions? How come it’s so difficult to land a job? I can’t answer for the industry as a whole, but I can certainly tell you what I am looking for when trying to fill an entry-level programmer position. ...
Exactly a year ago today, I put up the first article on Games from Within. It was a review of Tom DeMarco’s book Slack. I thought it would make for a nice, symmetrical bookend to wrap the year up with a review for another book by DeMarco: Waltzing with Bears. As the subtitle indicates, Waltzing with Bears deals with managing risk in software development projects. Managing risk, not reducing risk, or removing risk. Do you think that low risk or even no risk is a good thing? Think again. One of the central points of the book is that a project with no risk is not worth doing. Yes, you read that correctly. Intrigued? Go and read the book right now. ...
Update (Apr 2010): It’s been quite a few years since I originally did this comparison. Since then, Charles Nicholson and I created Unit Test++, a C/C++ unit-testing framework that addresses most of my requirements and wish-list items. It’s designed to be a light-weight, high-performance testing framework, particularly aimed at games and odd platforms with limited functionality. It’s definitely my framework of choice and I haven’t looked at new ones in several years because it fits my needs so well. I definitely encourage you to check it out. -——— One of the topics I’ve been meaning to get to for quite a while is the applicability of test-driven development in games. Every time the topic comes up in conversations or mailing lists, everybody is always very curious about it and they immediately want to know more. I will get to that soon. I promise! In the meanwhile I’m now in the situation that I need to choose a unit-testing framework to roll out for my team at work. So, before I get to talk about how to use test-driven development in games, or the value of unit testing, or anything like that, we dive deep into a detailed comparison of existing C++ unit-testing frameworks. Hang on tight. It’s going to be a long and bumpy ride with a plot twist at the end. ...
The GameTech Leadership Summit was the second part of this year’s Game Tech Seminars. Underneath a somewhat confusing name, it really was an analysis of the tools and technology in games today. The first day is where the real meat of this second part was. It was a postmortem/analysis of the tech involved in some of the most successful games today (Halo 2, Half Life 2, The Sims 2, and Stranger) done by the tech lead (or someone close to that position) for each of the teams. Each of the talks was packed with information and some of them are freely available online, so I’m not even going to try to summarize the talks. Instead, this is going to be more of a highlight of things that caught my eye or I thought were particularly important. ...
They say good things come in small packages. That was certainly true of this year’s Game Tech Seminars. It was a four-day intensive conference dealing with very specific topics (realistic characters and engine/tools technology) with a very impressive list of speakers. The best part though, was the attendees. There were only about 80 people total in the conference (due in no small part to the hefty price tag attached to the conference, I’m sure), and they were mostly tech leads or directors of technology of their companies. It was great to see lots of familiar faces, but also a lot of new ones I only knew through the Internet or not at all before. The great discussions following each session, or even over lunch or dinner were worth the price of admission alone. ...
