[haXe] Bug in Flash MovieClip Drawing API?

[Louis-Philippe Maurice]

It's not a bug, you're calling endFill() at the wrong place. Here's the fix:

// 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);
 
 
  // 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);
  mcTest.endFill();
  // 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);
 }
}
