JavaFX: Draw Polygon on Canvas

Newbie & Debugging Questions
#1

Hi guys

I’m still developing a platformer, but I don’t get to draw a polygon on my screen. Im using a Group-Node as the root, that is used as a parent for the Scene-Object. Then canvas is then added. I’m not using a Layout/Stack-Pane/Grid-Pane…

I’m having a player object that is containing an Object of class HUD(displaying stats and stuff). I can draw Images without problems, but how can i draw a Rectangle/Polygon onto a canvas?


@Override
	public void start(Stage primaryStage) throws Exception 
	{
		primaryStage.setTitle("Platformer");

		Group root = new Group();
		
		Scene scene = new Scene(root, WIDTH, HEIGHT);
		
		Canvas canvas = new Canvas(WIDTH,HEIGHT);
		root.getChildren().add(canvas);

		GraphicsContext gc = canvas.getGraphicsContext2D();
		
		MapManager.getInstance().loadAllMaps("maps");
		
		tileMap = MapManager.getInstance().getCurrentTileMap();
		
		player = new Player(tileMap);
		player.setX(64);
		player.setY(64);
		
		scene.setOnKeyPressed(
				event -> {
					String code = event.getCode().toString();
					
					if(code == "W")
					{
						player.setJumping(true);
 					}
					if(code == "A")
					{
						player.setLeft(true);
					}
					if(code == "D")
					{
						player.setRight(true);
					}
				});
		
		scene.setOnKeyReleased(
				event -> {
					String code = event.getCode().toString();
					
					if(code == "A")
					{
						player.setLeft(false);
					}
					if(code == "D")
					{
						player.setRight(false);
					}
				});
		
		AnimationTimer at = new AnimationTimer()
		{
			@Override
			public void handle(long now) 
			{
				update();
				render(gc);
			}
			
		};
		at.start();		
		
		primaryStage.setScene(scene);
		primaryStage.show();		
	}

Any ideas how to?
