Actually it call's functions "line()" and "arrow()", but you forgot
to mention where application should draw line!!
function line(x1, y1, x2, y2) {
moveTo(x1, y1);
lineTo(x2, y2);
}
it should look like
movie_clip.moveTo(x1,y1);
movie_clip.lineTo(x1,y1);
You need to send additional parameter to line function that contain
movieclip where you want to draw that line!
Best regards
