[osflash] haxe: bitmapdata on the fly example, anyone?

[Jun Kaddy]

Thanks for the help. I've extended your example a bit and I'm on my way to making Lemmings in HaXe, except I've run into a bit of a snag where flash9 differs from what I'm used to.

Before I was using something like follows to make the mainloop of my programs:

private var _container : MovieClip;
...
 _container = flash.Lib._root.createEmptyMovieClip ("Container", 1);
_container.onEnterFrame = mainLoop;
...
private function mainLoop () : Void
{
  Tick += 1;
....
}

Apparently not only has MovieClip moved into display in flash9 but it no longer has a onEnterFrame method.  So, I don't know how to do something similar in flash9.  I'm assuming the nextFrame function in MovieClip is essentially the same as the onEnterFrame was before, but I'm not sure how to use it.  When I try flash.Lib.current.nextFrame = mainLoop; I get an error "Main.hx:37: characters 8-35 : Cannot redefine method with Flash9 : please use 'f9dynamic' before method declaration"

        instance = new Main();
    }

    function new ()
    {
        img = new Image( 640, 480 );
        flash.Lib.current.addChild( img );
        img.drawRectangle( 0, 0, 100, 100, 0xff0033cc );
        img.drawRectangle( 20, 20, 60, 60, 0xff006400 );

        //img.data.fillRect(new Rectangle(0, 0, 20, 20), 0xffffffff);
