Linux Game Programming w/CD (Prima Tech's Game Development)

Mark Collins, Linux video game Programming (Prima, 2001)

The major challenge with analyzing desktop books which are six years previous is that, good, they are six years previous. this isn't an incredible challenge within the home windows international; as we've seen, occasionally the most up-tp-date home windows expertise will remain round much longer than the carrier contracts mandate. That, even if, is nearly by no means the case with Linux, the place a huge pool of builders pretty well guarantees that issues will develop and alter on a per thirty days, if now not day-by-day, foundation. nonetheless, the fundamentals of the required wisdom to get less than the hood and tinker with Linux will carry precise, so it is not like there is completely not anything to achieve from a ebook like this if you are a complete newb. (Sorry, I despise that spelling, but when i exploit the right kind one, Amazon filters it for being one letter off from a definite slang time period they do not appear to like. )

I am, actually, that newb. Having eventually thrown Microsoft over for solid in each point of my existence i will be able to (I nonetheless hold a home windows field round for video games, and i've to take advantage of it at work), all these database and video game tasks i used to be engaged on should be Linux initiatives now. So i began with what i'll get on the library, Collins' six-year-old treatise on Linux video game programming. First, permit me say that in case you are trying to find hands-on educational stuff, this isn't the ebook for you. Collins is extra drawn to getting you to appreciate the concepts--why you need to do anything, instead of what it really is you must do. whereas this is often evidently a great factor and ends up in programmers who comprehend extra of what they are on approximately, it really is most likely worthy a caveat emptor for the folk who're simply trying to find shortcuts, or solutions to a selected challenge. the second one factor to be stated, then, is that online 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 style (an whole bankruptcy, for instance, is dedicated to the OpenSource debate), a number of the particular instruments Collins talks approximately, and the entire high-level innovations, are appropriate to video game designers who software for any platform. therefore, i may cross methods right here; criticize the ebook for probably not being approximately Linux particularly, or compliment it for being universal?

The challenge is, i will not do one or the opposite. How beneficial you will find it's going to most likely depend upon how a lot analyzing you could have already performed on designing video games and constructing video games with C++. If you've gotten performed a lot, you'll get the main worthy out of the chapters on SDL and openGL/openAL; differently, learn the whole lot. ***

Example text

Anyone can use this facility; it does not require superuser status. However, as with write and talk, only messages from the superuser override users’ mesg n commands. A good example of such a message would be to give advance warning of an imminent but unscheduled system shutdown. The Message of the Day Login time is a good time to communicate certain types of information to users. It’s one of the few times that you can be reasonably sure of having a user’s attention (sending a message to the screen won’t do much good if the user isn’t at the workstation).

Accordingly, the Unix view of files and its standard directory structure are among the first things a new administrator needs to know about. * The base of this tree is a directory called the root directory. The root directory has the special name / (the forward slash character).

One of SMIT’s most helpful features is command preview: if you click on the Command button or press F6, SMIT displays the command to be executed by the current dialog.
