    Anyone following my tribulations with capturing screen output on html5 might be interested in this. It turns out that the problem is indeed related to clearing the drawing buffer after rendering. It is probably the async nature of the browser interactions or something similar that makes it such a problem in html5. Now if I modify 
    lime/_internal/backend/html5/HTML5Window.hx
    where the canvas context is first created to set this property true then you can capture the image properly with 
    FlxG.stage.context3D.drawToBitmapData(bmp);
    .
    Copy code
    hx
                var options =
                    {
                        ...
                                                ...
                        preserveDrawingBuffer: true,
                                                ...
                    };
    The problem is that the context cannot be modified once created. And while you can specify some attributes at creation you cannot specify this one. So .... hmmmm.... no nice solution yet but it's progress.

    My current theory now is to create a filter that writes to a custom framebuffer and then read that back. But there is complexity in having to render twice and then read back. Not sure if there are better options

    wait context3D works on html5?
  • h
    Yep. The target stuff is further down the stack
  • r
    is there a way to get the bitmap data from FlxG.camera. I tried buffer and screen but they return null.
  • a
    try drawing 
    camera.canvas
    on a new bitmapdata
  • a
    make sure that the camera is in FlxG.cameras.list (nvm FlxG.camera is already in cameras.list)
  • r
    It works! Thanks!
  • a
    np!

    For some reason, sprites aren't appearing on my project, does anyone know why this could be the reason? code:
    Copy code
    hx
lass InitLoadingState extends FlxState
{
    public function new()
    {
        super();
        Parser.init("assets/engine/data/parser_rules.json");
        Drinks.init("assets/data/drinks/drink_files.txt");

        #if debug
        trace(Parser.parserRules);
        trace(Drinks.drinks);
        #end
    }

    override function create()
    {
        var sprite = new FlxSprite().makeGraphic(400, 200);
        add(sprite);
        // FlxG.switchState(new PlayState());
        super.create();
    }

    override function update(elapsed:Float)
    {
        super.update(elapsed);
    }
}

    lime, openfl & flixel are all up to date
  • d
    the black square is probably the sprite
  • d
    it'll just be easier to tell which one is the sprite if you comment the line out, run it, and see if something disappeared or not
  • t
    this is a 1920x1080 resolution project
  • t
    and flxsprite makegraphic() defaults to white
  • t
    even doing something like
    Copy code
    hx

        var sprite = new FlxSprite().makeGraphic(400, 200, FlxColor.BLUE);
    yields the same results
  • t
    created a new project... it worked fine until i changed the project resolutinon
  • t
    well now it works?
  • t
    an wtf
  • b
    is there a way to turn off antialiasing on normal FlxText?
  • m
    Setting it manually
  • m
    text.antialiasing = false;
  • b
    ohh alr
  • m
    It should be off by default tho
  • b
    i read that that doesn't work on google but i will try it
  • m
    thats weird
  • b
    i'm going for like
  • b
    a raster text appearance
  • b

  • b
    yeah no it didn't work, i want all the transparent pixels gone
