Game: Line draw (Advanced)

1

OK, I’ve been trying to do this for two months now and I cant do it. I’ve tried several tuts. to helpp me and I’ve achived nothing. All of the code is complete (just need to add in the comments). All I need is for some advance flash user (and I know there’s a few out there) to help me with a bit of code. I am making a car game, like GTA, and what I need is when the user presses the hand brake (space) it draws a line that it suppose to be a skidmark. Any help would be greatly appriciated and the user will be placed in the credits.
