Question

I have a component (link to Test class) which contain one line in it, and I put one point of this line to (0, 0).

Then drag it to Flash(fla), and get its Shape in AS3 like:

// in Test.as
// assume that the movie clip only contain one line.
var line:Shape = Shape(getChildAt(0));

And I can get one point of this line which is x and y of var line. But how to get another point of this line?

Edit:
Ignore component stuff above, here has another question but I guess it pretty much the same as the question above:

Draw a line from (0, 0) to (10, 10) and draw another line from (10, 0) to (0, 10), how to get those lines of two-point form in AS3?

If I access them as Shape then I get two similar shapes which have same x, y, width and height values. Does AS3 has some way to access line as a REAL line not just a shape? or does it has any way I can calculate it out?

Answer 1

I got a nice tricky way to do this eventually.

Here we go:

1. create a symbol and draw a line from origin point (0, 0) to (x, 0)
2. link this symbol to your source code, let’s call Line.
3. drag this symbol to stage, and rotate, scale it if need.

4. in code Line:

   var v:Point = new Point(getBounds(this).right, 0);
   v = localToGlobal(v);
   

   then (x, y) and (v.x, v.y) can represent this line.
