' Line Tutorial Page Two Now that we have initialized our variables, let's start calculating
//First we check if the x and y coordinates of our points are the same
//If both points have identical x and y coordinates
// then they are in the same spot and we no longer have a line

if((myClip1._x == myClip2._x) && (myClip1._y == myClip2._y) )
// we need to 'clear' our line so that we
// do not try to draw a line that does not exist!

{
drawLineInThisClip.clear();
}
else
{
//first: clear last rendering of line before redrawing
//If you didn't clear you would leave a trail of lines

drawLineInThisClip.clear();
//Set the lineStyle of our lines based on the variables we initialized
// at the top of our function

drawLineInThisClip.lineStyle(lineThickNess,lineRGB,lineAlpa, true ,'normal','round', 'miter');

// If the slope is Infinity or -Infinity, it's a vertical line
if(_slope == Infinity || _slope == -Infinity)
{
//Move the "pen" of our line ('moveTo') to the x value of 1
// point & a y value of '0' which is the top of the Stage
drawLineInThisClip.moveTo(myClip1._x, 0);
//Draw the line to ('lineTo') the same x value of our point
// point and a y value of Stage.height which is the
//the very bottom of theStage
// Using myClip1 was arbitrary. Both clips have the same x.
drawLineInThisClip.lineTo(myClip1._x,Stage.height);
