Mark Collins, Linux video game Programming (Prima, 2001)
The major challenge with examining machine books which are six years previous is that, good, they are six years previous. this isn't an immense challenge within the home windows global; as we've seen, occasionally the most up-tp-date home windows know-how will remain round much longer than the provider contracts mandate. That, even if, is nearly by no means the case with Linux, the place a big pool of builders pretty well guarantees that issues will develop and alter on a per 30 days, if no longer day-by-day, foundation. nonetheless, the fundamentals of the mandatory wisdom to get less than the hood and tinker with Linux will carry precise, so it isn't like there is totally not anything to achieve from a e-book like this if you are a complete newb. (Sorry, I despise that spelling, but when i take advantage of the proper one, Amazon filters it for being one letter off from a undeniable slang time period they do not appear to like. )
I am, in reality, that newb. Having eventually thrown Microsoft over for strong in each point of my existence i will (I nonetheless retain a home windows field round for video games, and i've to take advantage of it at work), all these database and online game tasks i used to be engaged on must be Linux tasks now. So i began with what i may get on the library, Collins' six-year-old treatise on Linux online game programming. First, enable me say that in case you are trying to find hands-on instructional stuff, this isn't the ebook for you. Collins is extra drawn to getting you to appreciate the concepts--why you must do anything, instead of what it truly is you need to do. whereas this is often evidently a superb factor and results in programmers who comprehend extra of what they're on approximately, it is most likely worthy a caveat emptor for the folks who're simply trying to find shortcuts, or solutions to a particular challenge. the second one factor to be acknowledged, then, is that video game layout itself is the main transportable a part of any online game undertaking. whereas Collins does delve into a few issues which are extra acceptable to Linux improvement than the other kind (an complete bankruptcy, for instance, is dedicated to the OpenSource debate), the various particular instruments Collins talks approximately, and all the high-level options, are acceptable to online game designers who application for any platform. hence, i'll cross methods the following; criticize the ebook for not likely being approximately Linux particularly, or compliment it for being universal?
The challenge is, i cannot do one or the opposite. How necessary you will find it's going to most likely rely on how a lot analyzing you've gotten already performed on designing video games and constructing video games with C++. If you may have performed a whole lot, you'll get the main worthy out of the chapters on SDL and openGL/openAL; differently, learn the whole lot. ***
