578 Part IV . Running Applications Freeciv Freeciv

Sunday, July 22nd, 2007

578 Part IV . Running Applications Freeciv Freeciv is a free clone of the popular Civilization game series from Atari. A commercial port of Civilization Call to Power to Linux was created a few years ago by Loki Games (described later in this chapter). With Freeciv, you create a civilization that challenges competing civilizations for world dominance. The commonly distributed version of Freeciv contains both client software (to play the game) and server software (to connect players together). You can connect to your server and try the game yourself or (with a network connection) play against up to 14 other players on the Internet. To install Freeciv, check out the download page on the www.freeciv.org Web site. Choose your language, start downloading, install, and have fun. You can start Freeciv from a Terminal window by typing: $ civ & Figure 22-2 shows the two windows that appear when you start Freeciv. The Connect to Freeciv Server window contains your username, host name, and port number. The Freeciv window is where you play the game. If Freeciv won t start, you may be logged in as root. You must be logged in as a regular user to run the civ command. Figure 22-2: Play Freeciv to build civilizations and compete against others. Note

576 Part IV . Running Applications The games (Web site design)

Saturday, July 21st, 2007

576 Part IV . Running Applications The games on the KDE menu range from amusing to quite challenging. If you are used to playing games in Windows, KMines and Patience will seem like old favorites. KAsteroids and KPoker are good for the mindless game category. For a mental challenge (it s harder than it looks), try KSokoban. For a challenging multiuser game on the GNOME menu, try Freeciv. And of course there is Chess (XBoard version of gnuchess). Boson is a fun real-time strategy that runs on KDE desktops. Although the game is still in its early stages of development (0.10 release), it s a good way to try out the capabilities of your gaming hardware in Linux. You can download it from http:// boson.eu.org/download.php. The following sections describe a couple of the more interesting games that are distributed with common Linux distributions. Chess Games Chess was one of the first games played on computer systems. While the game hasn t changed over the years, the way it s played on computers has. Most chess programs that come with Linux let you play against the computer (in text or graphical modes), have the computer play against itself, or replay stored chess games. You can even play chess against other users on the Internet using Internet Chess Servers (ICS). The XBoard program is an X-based chess game that provides a graphical interface for gnuchess. GNU Chess (represented by the gnuchess package) describes itself as a communal chess program. It has had many contributors, and it seeks to advance a more open and friendly environment of sharing in the chess community. With XBoard, you can move graphical pieces with your mouse. To play against the computer, click Games.Chess from the Red Hat menu, then start by just moving a piece with your mouse. While in the XBoard window, select Mode.Two Machines to have the computer play itself. Select File.Load Game to load a game in Portable Game Notation (PGN). Figure 22-1 shows the XBoard window with a Two Machines game in progress. You can use XBoard to play online against others by connecting an XBoard session to an Internet Chess Server (ICS). To start XBoard as an interface to an ICS, type the following command line: $ xboard -ics -icshost name In this example, name should be replaced by the name of the ICS host. In ICS mode, you can watch games, play against other users, or replay games that have finished. The ICS host is a gathering place for enthusiasts who want to play chess against others on the Internet, watch games, participate in tournaments, or just meet chess Note

Web design careers - Chapter 22 . Gaming Alone and Online 573

Friday, July 20th, 2007

Chapter 22 . Gaming Alone and Online 573 X Window Games The X Window System created a great opportunity for games in Linux/Unix systems to become graphic-based rather than character-based, so that instead of having little character symbols representing robots and arrows, the games could actually show pictures of little robots and arrows. A lot of entertaining games run in X. Unless otherwise noted, all of the X games described in this section are free. Also, the GNOME and KDE environments that come with most desktop Linux distributions (described in Chapter 3) each have a set of games associated with it. GNOME Games GNOME games consist of some old card games and a bunch of games that look suspiciously like ones you would find on Windows systems. If you are afraid of losing your favorite desktop diversion (such as Solitaire, FreeCell, and Minesweeper) when you leave Windows, have no fear. You can find many of them under GNOME games. Table 22-1 lists the GNOME games available with most GNOME desktop systems from the panel menu, including Fedora Core 3. See the GNOME Games site (www.gnome.org/projects/gnome-games) for further details. Many KDE games (see Table 22-2) are available if you have a KDE desktop installed. Table 22-1 GNOME Games Game Description AisleRiot (solitaire) Lets you select from among 28 different solitaire card games. Chess Gnuchess game in X. (Runs the xboard and gnuchess commands.) Chromium Configuration Set options such as skill level, screen size, and sound for Chromium. Chromium Deliver supplies to troops in battle in this action game. FreeCell A popular solitaire card game. Freeciv (Isometric tileset) In this strategy game, you try to lead your civilization to extinguish all others. (Uses Isometric tile set to represent cities, oceans, and other terrain.)

Web hosting account - 572 Part IV . Running Applications One feature

Friday, July 20th, 2007

572 Part IV . Running Applications One feature that many games may require of your video card is Direct Rendering Infrastructure (DRI). Whether you are running the games using Cedega or natively in Linux, to play demanding games in Linux you need a card that supports DRI to do hardware acceleration. Following is a list of manufacturers whose video cards support DRI. The list is from the DRI project site (http://dri.sourceforge.net/). . ATI Technologies Chipsets from ATI Technologies that support DRI include the Mach64 (Rage Pro), Radeon 7X00 (R100), Radeon 2 / 8500 (R200), and Rage 128 (Standard, Pro, Mobility). Cards based on these chipsets include All-in- Wonder 128, Rage Fury, Rage Magnum, Xpert 99, Xpert 128, and Xpert 2000. . 3dfx If you can find a used unit on eBay, there are several 3dfx cards that support DRI. In particular, the Voodoo (3, 4, and 5) and Banshee chipsets have drivers that support DRI. Voodoo 5 cards support 16 and 24 bpp. Scan Line Interleaving (SLI), where two or more 3D processors work in parallel (to result in higher frame rates), is not supported for 3dfx cards. . 3Dlabs Graphics cards containing the MX/Gamma chipset from 3Dlabs have drivers available that support DRI in Linux. . Intel Supported video chipsets from Intel include the i810 (e, e2, and -dc100), i815, and i815e. . Matrox The Matrox chipsets that have drivers that support DRI include the G200, G400, and G450. Cards that use these chips include the Millennium G450, Millennium G400, Millennium G200, and Mystique G200. . NVIDIA Cards from NVIDIA are not supported by DRI because NVIDIA has not released hardware specifications to DRI developers. However, NVIDIA cards work for most Linux games. To get NVIDIA drivers, which are produced by NVIDIA but are not open source drivers, you must download them from the NVIDIA Web site (www.nvidia.com). On the NVIDIA home page, click the download button and follow the instructions for downloading and installing the correct drivers for your card. RPM packages are available. To find out whether DRI is working on your current video card, type the following: $ glxinfo | grep rendering direct rendering: Yes This example shows that direct rendering is enabled. If it were not supported, the output would say No instead of Yes. Even if DRI is not supported, you may experience the best game play with a high-end card from either ATI or NVIDIA. While DRI can be important, many games implement OpenGL rendering, which is a feature supported by both NVIDIA and ATI video cards. Both companies have specific driver requirements, so make sure you research the cards, driver requirements, and any gamespecific issue before you plop down big money on a top-tier 3D video card.

Gaming Alone and Online As (Unlimited web hosting) Linux has grown

Thursday, July 19th, 2007

Gaming Alone and Online As Linux has grown in popularity, the need and availability of Linux-based entertainment options has naturally increased. From simple parlor games to fast-paced OpenGL First Person Shooters (FPS), there have been great strides recently in Linux gaming opportunities. In fact, the advance of processor-devouring 3D games has helped drive improvements in computer technology in general. Gaming software that you can use with Linux is a mixed bag of sorts. A lot of the old software is still around (and is free), while newer software is available in demo form but costs money to get a full version. Some experts predict that gaming will be the software category that brings Linux into homes. The unfortunate truth is that many of the current hot titles still need to be coaxed onto Linux with some kind of Win32 emulation, although even this is getting easier and more dependable. While the number of commercial game applications created specifically for Linux is fairly limited at the moment, like everything else in Linux, more are becoming available each day. This chapter examines the current state of gaming in Linux, including the basics on getting your gaming environment going, and hardware considerations for gaming. It describes the free games (mostly fairly simple X Window games) that come with various Linux distributions or that can be easily downloaded. For running games that were created for other platforms, this chapter describes game emulators such as Cedega. It also explores some popular commercial games that have demo versions available for Linux. If you like the demos, you can purchase these games, which run natively in Linux. 2C H A2P2T E R . . . .
