[Xerte] drawArrow()

[Paul Swanson]

Excellent! That's exactly what I was looking for.
 
Thanks Julian!

	Hi,
	 
	drawArrow was added to support the drawing tools. It always
draws arrows at 0,0. You can of course set the _x and _y of the clip /
icon you are drawing into to position the arrow, and to rotate it you
can set the _rotation property of the movieclip. 
	 
	You might want to look at arrowTo(x1,y1,x2,y2,[size], [spread])
which conveniently connects two points with an arrow. Size and spread
are optional, but control the appearance of the arrowhead. Size is the
length of the arrow head from its tip to its base, spread is an angle in
radians that defines how sharp the arrow is. If you want to do this
calculation in degrees it would be:
	 
	ar.arrowTo(100,100,300,100, 20, 45 * Math.PI / 180); //creates
an arrow with a 90 degree point, as spread applies on each side.
	 
	Play around with the values to see what you like best,
	 
	Julian

		Sorry to post so many questions lately. Can anyone
enlighten me on the following? 

		I found that I can draw an arrow with code, but I can't
find a list of the arguments the method takes. If I use the following to
create an arrow:

		arrow2.lineStyle(2,0xFF0000,100); 
		arrow2.drawArrow(100,100,300,10); 

		I get a red arrow that is 300 pixels long and 10 high,
but it seems to start at x=0 y=0, no matter what I use for the first two
arguments, even if I use empty strings in place of integers. And I
imagine there is an angle argument. Is there any documentation anywhere
that lists what these arguments are? I've been Googling all morning and
haven't found anything.

		I know I can use moveTo() and rotateTo() to position the
arrow, but it would be nice to know what arguments the method takes, or
where to look for this information.

		Thanks!
