Uncaught exception - Invalid field access : addClone

[weitnow]

Hello and good evening :)

I discoverd haxe and haxefilxel recently and have already a question.
I have a PlayState-Class with a addClone-Method which should instantiate a Player-Object.
If I call addClone() in the create-Method of PlayState it works.

However, if I call it from a Player-Object it creates a "Uncaught exception - Invalid field access : addClone" and the game crashes. I have no idea why? Any help is much appreciated 👍

Look for <--------------------------------------- in the two classes :)

class PlayState extends FlxState
{
	public var map:FlxTilemap;
	public var player(default, null):Player;
	public var items:FlxTypedGroup<FlxSprite>;
	public var enemies:FlxTypedGroup<Enemy>;
	public var clone(default, null):Player;
	private var _hud:HUD;
	override public function create():Void
	{
		items = new FlxTypedGroup<FlxSprite>();
		player = new Player(this);
		_hud = new HUD();
		enemies = new FlxTypedGroup<Enemy>();

		LevelLoader.loadLevel(this, "playground");

		add(player);
		add(items);
		add(_hud);
		add(enemies);

		FlxG.camera.follow(player, FlxCameraFollowStyle.PLATFORMER);
		FlxG.camera.setScrollBoundsRect(0, 0, map.width, map.height, true);

                // THIS WORKS !!!  <---------------------------------------
		addClone();
		super.create();

	}
	public function addClone():Void
	{
		clone = new Player(null);
		add(clone);
	}

class Player extends FlxSprite
{
	private static inline var ACCELERATION:Int = 320;
	private static inline var DRAG:Int = 320;
	private static inline var GRAVITIY:Int = 600;
	private static inline var JUMP_FORCE:Int = -280;
	private static inline var WALK_SPEED:Int = 80;
	private static inline var RUN_SPEED:Int = 140;
	private static inline var FALLING_SPEED:Int = 300;

	var gamestate:PlayState;

	public var direction:Int = 1;
	public var cloned:Bool = false;

	public function new(game:PlayState)
	{
		super();
		loadGraphic(AssetPaths.player__png, true, 16, 16);
		this.gamestate = game;

		animation.add("idle", [0]);
		animation.add("walk", [1, 2, 3, 2], 12);
		animation.add("skid", [4]);
		animation.add("jump", [5]);
		animation.add("fall", [5]);
		animation.add("dead", [6]);

		setSize(8, 12);
		offset.set(4, 4);

		drag.x = DRAG;
		acceleration.y = GRAVITIY;
		maxVelocity.set(WALK_SPEED, FALLING_SPEED);
	}

      
        // THIS CRASHES THE GAME !!!  <---------------------------------------
	public function clone_self()
	{
		gamestate.addClone();
	}

where is clone_self() being called?

Try debugging via VSCode to see exactly where things are failing

Thank you...I wasn't aware that you can debug like that :)....I always used neko and pressed f2 but because the game crahsed I couldn't investigate in the build in debugger...but now I understand that only html5 and cpp-builds support breakpoints...will try to figure out what was the problem...thanks a lot
