About SuperTuxKart

General questions about SuperTuxKart (STK for short).

What is SuperTuxKart

SuperTuxKart is a Free 3d kart racing game; we want to make the game fun more than we want to make it realistic. You can play with up to 4 friends on one PC, racing against each other or just try to beat the computer (a network multiplayer feature is under development).

See the great lighthouse or drive through the sand and visit the pyramids. Race under water or in space, watching the stars passing by. Have some rest under the palms on the beach (watching the other karts overtaking you :) ). But don't fall into the volcano!

You can do a single race against other karts, compete in one of several Grands Prixs, or try to beat the high score in Time Trials on your own.

What is the history of STK?

First there was TuxKart. Work on this happened (roughly) between April 2000 and March 2004. In June 2004, the 'Game of the Month' project of the Linux Game Tome decided to improve TuxKart. This was done between June and December 2004. Unfortunately, this projected ended in a big disagreement, and it was finally decided to save the current state as 'SuperTuxkart'. While some graphical improvements were done, the code base itself was very unstable and basically unplayable. Nobody worked on (Super)Tuxkart till 2006.

Joerg Henrichs (aka hiker) picked up SuperTuxKart in 2006, fixed the outstanding bugs and performance issues without any further involvement of the original game designer or the GotM project. With the help of Coz a first release of STK was done in September 2006.

In May 2007 version 0.3 was released, adding highscore lists, a new track (Island) and the bomb and MacOSX and OpenAL support.

February 2008 saw the 0.4 release, which used Bullet Physics to improve the collision handling. Auria joined and started improving tracks (Shifting Sand, Lighthouse).

Version 0.5 was released in May 2008, and it included many improved tracks, challenges that need to be unlocked, the Follow-the-leader game mode and translations (OS language detector and matching to closest translation).

Version 0.6 was released on 22 January 2009. It has significantly improved gameplay: more physics, using Nitro and skidding. The sound system was improved, more interesting music was added and many new tracks and karts were added. It also saw the first special multi-player map for 3-Strikes battle and new items to use.

Version 0.7 was released on December 20, 2010, which contains several significant improvements including: new rendering engine(Irrlicht), new GUI, kart and track animations, new tracks, karts, and items and support for shortcuts/alternative paths. 0.7.1, 0.7.2, 0.7.3 were released shortly after with more improvements.

Version 0.8 was released on december 2012, adding a story mode and new challenge, with an improved AI, skidding, reverse mode, new tracks and music. The menu was also changed

Hardware requirements

Recommended

Minimal (the game might be slow)

Optional

My computer is too old to run STK. What should I do ?

You can try to run the game, and maybe your lucky and it works. If it doesn't we are sorry for you, but we can't support everything. We have a limited amount of manpower and spending time to support old GPU would basically mean no new and advanced features.

Playing STK

Questions often asked when playing STK.

The computer shot backwards - how can I do this?

Most items (bowling ball, cake, plunger) support to be used backwards. Just fire while looking backwards.

What does the plunger do?

The plunger has two different ways of working: if shot forwards, it will come with a rubber band attached to it. If you hit another kart, you will be pulled forwards toward the kart, and the other kart will be pulled backwards. Ideal to overtake an opponent if executed skillfully. You can also shoot the plunger backwards - if you hit a computer the kart will be confused, and accelerate and steer less. If a player is hit, you will see a big plunger in the middle of the screen, and can't see the road anymore :)

Certain keys don't work if I use the keyboard!

This problem is reported in several different variations: e.g. you might not be able to skid when turning left, or you can't shoot when turning right etc. Basically, certain keys don't work all the time. Unfortunately, this is a hardware restriction of your keyboard: most keyboards can not report all keys pressed at the same time, see Keyboards are evil for details. The only solution is either to try different key combinations till you find one that works (the default ones work on nearly all platforms), to get a special gamers keyboard (that can report all key pressed, independent on the number of keys and what keys are pressed), or to use a gamepad.

The AI cheats, I can't push their karts, while my kart is very often pushed and even starts to rotate

The AI is using the same commands (for e.g. steering and acceleration) a player can use, and the physics does not differentiate between a player and AI karts. So there is no cheating for the AI. But the AI can change the steering direction much more frequently than a player can, and so can react to being pushed and correct its course much more easily and more precise. You can see this effect in certain situation where the AI starts to 'shake' because it frequently changes direction. This is at the moment necessary to make the AI competitive. Once the steering algorithm is improved, we can hopefully reduce the shaking (which then would also make the AI karts easier to push).

How can I play STK on the internet?

The network support is under development. The basic support has been added in the Google Summer of Code 2013, but it's still not finished. See Networked Multiplayer (and pages linked from there) for more information.

I found a bug, how should I contact you?

First, look at the STK Bug tracker and open a new issues if your problem hasn't been reported yet. And please make sure that your bug doesn't fly away.

I suddenly got a big red circle on my screen, what's that?

If there's a penguin in the circle, someone's shot a plunger at your face =) . You can do that to others by throwing the plunger backwards (see the FAQ entry about throwing items backwards). If there is no penguin then it's a bug.

How do I install add-ons?

You can simply install all add-ons in-game! Look at In Game Add-On Manager for details.

Technical questions

What are the dependencies of STK?

Look at Dependencies

Where does STK store the user config file?

You can also watch the output in the terminal to see if there is a note on where the config files are stored or search for a file called "config.xml".

Known problems

Sound works, but it is constantly stuttering

This can also have several causes; often OpenAL complains about buffering problems if the game is running slow. If you have a soundcard with sample rate set to 44800 Hz or higher you will need to set OpenAL to use the same instead of the default 44100 sample rate. In Linux, the configuration file can be found at /etc/openal/alsoft.conf (can be copied to ~/.alsoftrc and changed there) and for Windows, these settings should go into %AppData%\alsoft.ini.

Most of the scene is white

Texture compression on intel.png If you're scene looks like the one shown above, try disabeling Texture Compression in the "advanced graphic options". See the Ticket on GitHub for more information.
