}


The last part shows the script for the movement calculated by the rotation of the car. but when i script it this way the rotation does not fit to the movement!
I changed somethin in the last part:
...
...
setProperty(_root.auto, _x, getProperty(_root.auto, _x)+(Math.cos(_root.auto._rotation/50)*(speed/10)));
setProperty(_root.auto, _y, getProperty(_root.auto, _y)+(Math.sin(_root.auto._rotation/50)*(speed/10)));
}

the /50 made it work a bit, but the movement does not really fit!! why??????? dl the movie: http://www.myfav.de/pics/formel1.zip

PLEASE ANSWER, THX
