[font=verdana, arial, helvetica][size=2]I am having a problem with this actionscript, its the same on many of the the tutorials here and i post it on my mc but it doesnt work. (except for the turning it just wont go forward or back)  
onClipEvent (enterFrame) {  
//This code will advance the car forward.  
if (Key.isDown(Key.UP)) {  
speed += 1;  
}  
// This will make the car go backwards  
if (Key.isDown(Key.DOWN)) {  
speed -= 1;  
}  
//The car will start to slow down after the speed of 25  
if (Math.abs(speed)\>25) {  
speed \*= .6;  
}  
// This will change the angle of the car  
if (Key.isDown(Key.LEFT)) {  
\_rotation -= 10;  
}  
if (Key.isDown(Key.RIGHT)) {  
\_rotation += 10;  
}  
// This will make the car move  
speed _= .98;  
x = Math.sin(\_rotation_(Math.PI/180))_speed;  
y = Math.cos(\_rotation_(Math.PI/180))_speed_-1;  
if (!\_root.move.hitTest(\_x+x, \_y+y, true)) {  
\_x += x;  
\_y += y;  
} else {  
speed \*= -.6;  
}  
}

If you can help me i would be thankful.[/size][/font]
