 # Check All Points Along a Line?

I’m using Flash 8 and AS2

I am attempting to make some code that checks whether or not a line that rotates around the screen is hitting a movie clip. Here is my code (with comments explaining it):

``````onClipEvent(enterFrame){
//center points
xc = _root.man._x;
yc = _root.man._y;
//the angle at where the point on circumfrence is
//length of the line / radius of circle
r = 181;
//formula to find the point on circumfrence
xp = xc + r * Math.cos(a);
yp = yc + r * Math.sin(a);
//point to check along the line between the two points
xnp = xp;
ynp = yp;
//if the line is visible (2 is the only frame it is visible on)
if(_root.man._currentframe == 2){
//while the point to be checked still isn't the same as the center point
while(xnp != xc){
while(ynp != yc){
//this code makes sure that the while() loop doesn't go on forever by setting a stop point for the minusing of the radius, then printing "No"
if(r < 0){
xnp = xc;
ynp = yc;
trace("No");
//if the object hits the certian point we are checking on the line, then it ends the while loop and prints "Yes"
}if(this.hitTest(xnp, ynp, true)){
trace("Yes");
xnp = xc;
ynp = yc;
//otherwise, the length of the line is subtraced by 1, so that we can check the next point along the beginning line
}else{
r--;
}
}
}
}
}

Needless to say, it doesn’t work. Basically, I keep getting the print “No” and I don’t know what’s wrong with my code!
Thanks for the help!
