To update Kart Racing Pro to a newer version:
1) download the latest version: http://www.kartracing-pro.com/?page=downloads
2) go to the folder where Kart Racing Pro is installed ( usually C:\Program Files\Kart Racing Pro\ ) and backup the addons ( paints, dashes, tracks, ... )
3) manually delete the Kart Racing Pro installation folder
4) optional: if a clean installation is needed, go to "My Documents"/PiBoSo/Kart Racing Pro/ and delete everything except the file license.ini and the "mods" folder
5) install the new build
6) restore the addons in the Kart Racing Pro installation folder

It is important to correctly setup the steering wheel.

1 ) In the steering wheel profiler, disable the centering spring and damping, or at least let the software override them.
2 ) Take note of the rotation ( the suggested value is 180 ).
3 ) Start Kart Racing Pro and click on Settings -> Input -> Calibration.
4 ) Move all the inputs to their full extent.
5 ) If you have other controllers connected as a separate device, select them from the dropdown menu at the top of the calibration screen.
6 ) Repeat from 4) until all controllers have been calibrated at the same time
7 ) Then leave all inputs of all controllers perfectly centered / released before pressing "Ok".
8 ) Click on the right of Controls -> Steer and steer LEFT to assign the control.
9 ) Under Advanced -> Steer, set deadzone to 0, linearity to 100 and leave smooth unchecked.
10 ) Enable force feedback and set strength to 100%, deadzone to 0% and linearity to 100%
11 ) Enable wheel rotation and set it directly or use the wizard. In both cases the value should match the rotation set in the profiler.

12 ) If you are experiencing vibration on straights, please try increasing force feedback deadzone in steps of 5. This shouldn't be needed on the Logitech G25 and G27.
13 ) If you feel the force in the center is a bit weak, you can try lowering the force feedback linearity.

This is how the FF curve looks like at 0 ( top ) and 100 ( bottom ) linearity:

Every now and then emails are sent to Kart Racing Pro contacts, inquiring about kart simulators for hire for events.
It would be nice to have a list of companies, if any exists, that can hire simulators ( preferably using Kart Racing Pro for the software ).
In order to give better information to the inquirers, it would also be useful to know the location of the company and where it can deliver.

The plan for the release 10 is to improve brakes simulation, replacing the "pressure" settings with more realistic ones.
In a kart, is it possible to choose between different master cylinders? If it is, is it possible for the front brakes, too?
It seems like there are at least 2 leverage settings for the foot pedal. Is it possible to set the leverage on the front brakes lever, too?

Kart Racing Pro beta9 released: http://www.kartracing-pro.com/?page=news

A clean install is strongly recommended.

Note: replays are not compatible with previous versions

Would it be possible, using an Arduino http://www.arduino.cc/ and a Can shield, to connect Kart Racing Pro with a real dash, simulating the real sensors?

To install this patch, overwrite kart.exe in Kart Racing Pro installation folder.

Changelog:
fix: chat color
fix: "data mismatch" error
fix: Logitech G27 leds

Starting with Beta8, physics files ( .cfg and .engn ) of the engines and karts ( .cfg ) are unencrypted.
It should now be possible to create new engines and new karts ( combining the different chassis / engines ).

Kart Racing Pro beta8 released: http://www.kartracing-pro.com/?page=news

A clean install is strongly recommended.

Note: replays are not compatible with previous versions

It is possible to create a texture animation of a few frames:

1) Create a text file in the same folder and with the same name of the 1st texture, but with extension .TXT ( for example, screen01.txt )
2) add the name of the other textures of the animations to the TXT file, one texture per line. For example:

Code Select Expand


screen02.tga
screen03.tga
screen04.tga
screen05.tga

3) export the MAP file
4) create another text file, in the same folder and with the same name of the MAP file, but with extension .SCR
5) for each animated texture, add the following structure:

Code Select Expand


texture0
{
name = screen01
loop_time = 200
}

where name is the name of the base texture ( without the extension ), and loop_time is the length of the animation, in milliseconds.

If you don't like installers or if you need to access the original data ( maybe to replace corrupted files ), it is possible to extract data from the installer.
Run the installer adding "-extract" to the command line.

Does anyone knows the optimal weight distribution for a kart, with and without the driver?
On manuals it is often suggested a weight distribution of 43.5 - 56.5, but is this with or without the driver? If it's without, how much does this change with the driver?

Maybe the feature was overlooked, or maybe it's not interesting, but since Beta7 it is possible to add custom helmets.
The procedure to create and integrate them is similar to dashes and intakes.

Happy 2013 everyone.

This year will bring Kart Racing Pro 1.0 

A little update on the progress on Kart Racing Pro.

The main focus so far has been on the tyre simulation model, to integrate some fixes and improvements:
1) fixed a bug that limits slip ( introduced in Beta7 )
2) temperatures should now be correct
3) fixed a bug that could generate wrong dynamic track surface data ( the random marbles bug should hopefully be fixed )
4) faster response to slip changes

Please use this thread to list all the multiplayer problems of Beta7.

The known issues are:
- dedicated server crashes
- sometimes the client hangs on "connection"

Please only post short, simple reports, preferably with the instructions to replicate the bug.

[Requirements:]

At the following link: http://www.kartracing-pro.com/downloads/kinect.zip it is possible to download 3 DLL that enable Kinect support in Kart Racing Pro.

Requirements:
Kinect for Windows and Windows 7 or 8 ( Kinect for Xbox shouldn't be supported. Please report if it works ).

Installation:
Unpack the zip file in Kart Racing Pro installation folder. Then enable "Face Tracking" in Settings -> Simulation -> Free Look.

Remarks:
It is possible to add, in Kart Racing Pro installation folder, a text file named "kinect.ini" to set a few parameters:

Code Select Expand


[face_tracking]
smooth = 5
yaw_multiplier = 200
pitch_multiplier = 100
roll_multiplier = 0


A very fast CPU is needed.
Gestures support will be added later.

It is possible to connect to a server from the web server list clicking on the "Join" link.
The "krp" url can be registered ticking the checkbox in the "URL" page during the Kart Racing Pro installation.

Warning: the following files are experimental and they modify the registry. Downloading them you agree that you are solely responsible for any damage to your computer system and any loss of data that may occur from their use.


It is also possible to use the following BAT file, that must be copied to Kart Racing Pro installation folder:
http://www.kartracing-pro.com/downloads/krp_url_reg.bat

The following BAT can be used to clean the registry:
http://www.kartracing-pro.com/downloads/krp_url_unreg.bat

Batch files must be run as administrator.

[EVENT]

It is possible to connect to a dedicated server or challenge server to receive live race data.
The feature is off by default and must be enabled:
http://forum.kartracing-pro.com/index.php?topic=8.0
http://forum.kartracing-pro.com/index.php?topic=3609.0
Only 1 client can connect to the server.

Communication is made with UDP sockets and strings terminated with "\n".

Send "CONNECT" followed by the connection password ( empty string if no password ).
Reply:
OK -> connected
FULL -> another client is already connected
WRONGPASSWORD -> wrong password

Send "START", followed by two parameter strings to start receiving data.
First parameter: either "0" or "1". If set to "1", the track centerline and the track position of the karts are sent, too.
Second parameters: either "0", "1" or "2". If set to "1", the contacts between karts are sent. IF set to "2", contacts between karts and walls are sent, too.

Data format is "MSG" followed by the message ID and then a stream of strings.
Send "ACK" followed by the message ID after each MSG.

Send "KEEPALIVE" every 15 seconds to keep the connection active.
The server sends "ALIVE" to report that the connection is active.

Send "DISCONNECT" to correctly close the connection.
