Tux Racer instance of free and open-source video game
Gameplay
Tux Racer is a racing game in which the player must control Tux across a mountainside. Tux can turn left, right, brake, jump, and paddle, and flap his wings. If the player presses the brakes and turn buttons, Tux will perform a tight turn. Pressing the paddling buttons on the ground gives Tux some additional speed. The paddling stops giving speed and in turn slows Tux down when the speedometer turns yellow. Tux can slide off slopes or charge his jumps to temporarily launch into midair, during which he can flap his flippers to fly farther and adjust his direction left or right. The player can also reset the penguin should he be stuck in any part of the course.Courses are composed of various terrain types that affect Tux's performance. Sliding on ice allows speeding at the expense of traction, and snow allows for more maneuverability. However, rocky patches slow him down,: 193  as does crashing into trees. The player gains points by collecting herrings scattered along the courses, and the faster the player finishes the course, the higher the score. Players can select cups, where progression is by completing a series of courses in order by satisfying up to three requirements: collecting sufficient herring, finishing the course below a specified time, and scoring enough points. Failing to meet all the criteria or aborting the race costs a life, and should the player lose all four lives, they must reenter the cup and start over.  During level selection, the player can choose daytime settings and weather conditions such as wind and fog that affect the gameplay. Maps are composed of three separately saved raster layers that each determine a map's elevation, terrain layout, and object placement.Development
Tux Racer was originally developed by Jasmin Patry, a student attending the University of Waterloo in Ontario, Canada, where he aimed to begin a career in the video game industry by pursuing a computer graphics degree. Development of the game began in August 1999 as a final computer graphics project in Computer Graphics Lab, and was completed in three days to positive class reception. A webpage for the game was then started, and someone suggested he release the game's source code. Patry felt that made sense due to Tux being the mascot for the open-source Linux, and continued to work on the game before publicly uploading it to SourceForge for Linux under the free GNU General Public License on February 28, 2000, hoping others would join in on developing it. This early version featured a very basic gameplay that consisted of Tux sliding down a hill of snow, ice, rock, and trees for Tux to avoid along the way. To write the game, Patry tended to use free premade content such as textures borrowed from websites, rather than original content made from scratch.In December 1999, Patry, fine arts students Rick Knowles and Mark Riddell, and computer graphics students Patrick Gilhuly, Eric Hall, and Rob Kroeger announced the foundation of the company Sunspire Studios to develop a video game project. Patry stated the game would have a massively multiplayer and a persistent universe with real-time strategy and first-person shooter components. Since their ideas were limited by that time's 3D engines, they embarked on creating their own, which according to Patry would make Quake 3 and Unreal engine look "tame" in comparison. Fine arts undergraduate classmate Roger Fernandez was chosen as the artist. The project was eventually abandoned due to it being a "massive undertaking," and in August 2000, Knowles suggested the company resume working on Tux Racer, which became their first official project. Continued development of the free version was swift; numerous elements such as herrings, jumping, and a soundtrack, as well as graphical improvements, were added in just three weeks. Porting the game from Linux to Windows was easy, as it used cross-platform tools such as OpenGL and Simple DirectMedia Layer. A major update including those improvements, version 0.60, was freely uploaded to SourceForge for both Linux and Windows on October 2, 2000. A minor patch for that release was often included in most Linux distributions,: 191  and a port for Macintosh was released in November 21, 2000.
