[haXe] Bug in Flash MovieClip Drawing API?

[Keith Hall]

Hello list,

I think I may have found a bug with the MovieClip drawing APIs. The way I
replicated the bug was simply to draw a square over a "cross". The bug
itself is a display issue, whereby
 a) it isn't drawn correctly - bit's that should be filled in aren't, and
lines that should be one color are a different color. Also, there is a black
rectangle to the right of the MovieClip!?
 b) it doesn't refresh the display correctly when you zoom in and move the
viewport. Artefacts are left from some of the lines.

I compiled it for Flash 7 and 8, testing with Flash Player 9. Also, I have
only tried compiling it with haxe v1.08, so I can't tell you whether it's a
new bug or not. (Sorry)

I don't know that this mailing list accepts attachments like a screenshot,
so I've made one available, along with the compiled movie and code
files from http://www.kingkeith.co.uk/testbed/test.htm

However, I shall also post the code here - I've made it as small as I
reasonably could while maintaining readability (and the bug, of course):

// file Test.hx
import flash.MovieClip;
class Test {
 static function main ():Void {
  var mcTest:MovieClip = flash.Lib.current.createEmptyMovieClip('mcTest',
flash.Lib.current.getNextHighestDepth());

  var intSize:Int = 50;
  mcTest.clear();

  // draw background
  mcTest.beginFill(0x00ccff);
  Test.drawSquare(mcTest, 0, 0, intSize);
  mcTest.endFill();

  // draw a cross over the background
  mcTest.lineStyle(2, 0xff0000, 100);
  mcTest.moveTo(0, 0);
  mcTest.lineTo(intSize, intSize);
  mcTest.moveTo(intSize, 0);
  mcTest.lineTo(0, intSize);

  // draw a smaller square (in the middle of the background and cross)
  //mcTest.lineStyle(0, 0xffffff, 0); // no line
  mcTest.lineStyle(1.0, 0xffff00, 100);
  mcTest.beginFill(0x00ff00);
  intSize /= 2;
  Test.drawSquare(mcTest, intSize / 2, intSize / 2, intSize);
  mcTest.endFill();
 }

 public static function drawSquare (mcDrawOn:MovieClip, fltX:Float,
fltY:Float, fltSize:Float):Void {
  Test.drawRect(mcDrawOn, fltX, fltY, fltSize, fltSize);
 }

 public static function drawRect (mcDrawOn:MovieClip, fltX:Float,
fltY:Float, fltWidth:Float, fltHeight:Float):Void {
  var fltEndX:Float = fltX + fltWidth;
  var fltEndY:Float = fltY + fltHeight;

  mcDrawOn.moveTo(fltX, fltY);
  mcDrawOn.lineTo(fltEndX, fltY);
  mcDrawOn.lineTo(fltEndX, fltEndY);
  mcDrawOn.lineTo(fltX, fltEndY);
  mcDrawOn.lineTo(fltX, fltY);
 }
}

// file Test.hxml
-swf test.swf
-main Test
-debug
-swf-version 7
-swf-header 400:300:40:ffffff
--flash-strict
--override


If this isn't a bug, but is something I am doing wrong please let me know,
and I will apologise for thinking that HaXe is flawed. :)
If it is a bug, perhaps someone could find more ways of replicating it, so
from this information, the bug could be fixed easier... :D

Thanks for your time
Keith Hall
