  • b
    yeah
  • b
    cool
  • b
    ok, so flixel question... just trying to understand some things
  • b
    why does this happen with flixel group
  • b
    but with flixel sprite its "all good"
  • b
    Copy code
    haxe
        var surface = new FlxSprite();
        surface.makeGraphic(20, 20, FlxColor.YELLOW, true);
        
        var group = new FlxSpriteGroup();
        group.add(surface);
        
        return group;
  • b
    if i return just the surface there, everything works as expected
  • b
    also, whats the use of FlxSpriteGroup? Is there magic happening? I mean, ComponentImpl in haxeui-flixel is FlxSpriteGroup... that contains a FlxSrpite as the surface, i think its a group because it also has the ability to display text and image (ie, buttons, labels, etc)
  • b
    however, if everything is screen coords whats the use in that? I mean, why not:
  • b
    Copy code
    haxe
ComponentImpl extends FlxSprite {
    var _text:Text;
    var _image:Image;

    handlePosition(x, y) {
        _text.x = x;
        _text.y = y;
    }
}
  • b
    I think @brave-kangaroo-30399 said he'd basically need to reimplement FlxSpriteGroup stuff? not sure what exactly haxeui needs / expects
  • b
    The group is out of convenience, and the sprite group for super convenience since positioning is already dealt with
  • b
    Realistically yeah it could just be a flat structure per component
  • b
    fair enough... with the collision sample, if you replace the create with a FlxSpriteGroup (instead of FlxSprite)... it behaves, strange
  • b
    There are children involved but I’d have to think about that for a sec
  • b
    no haxeui, just flixel stuff
  • b
    Oh
  • b
    It was to have something extremely similar to flash.display.Sprite
  • b
    As opposed to a more kha way
  • b
    Which is why Jens said it was kind of a hack class
  • b
    That class is on the list of big things we want to change, but... there’s a lot on that list
  • b
    just a mess around at the moment, but seems like its working more "correct"
  • b
    just hacking things about, destorying code to understand really
  • b
    main thing that seemed to be a big improvement is:
  • b
    typedef ComponentSurface = flixel.FlxSprite;
  • b
    ie, not the sprite group
  • b
    Oh yeah that doesn’t need to be a sprite group
  • b
    I haven’t gone through all your changes
  • b
    well, that is just for extends
  • b
    basically its 
    Component extends ComponenentImpl extends BlahBlah extends ComponentSurface
