Hello again forum, I hope you have a great day :)

I would like to continue my snake project game, and today i have decided to make a scoreboard for each fruits eaten.
However i have an issue,  i cannot display a UI text on my project even though i have followed tutorial in here

The program seems to crash too and wont run.

Any help given is appreciated. Cheers :)

 

Here's my code,  i insert the URL code into createScene function. 

<!DOCTYPE html>
<html>
<head>
	<title>Snake Game</title>
	<script src="babylon.js"></script>
	<script src="hand-1.3.7.js"></script>
	<script src="babylonObjLoader.js" ></script>
	<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<canvas id="mycanvas"></canvas>
	<script>

			/*var camera = new BABYLON.FreeCamera("FreeCamera", new BABYLON.Vector3(0, 1, -15), scene);

			camera.attachControl(canvas,false);

Thank you for your reply,

I have managed to solve this issue, thank you for your attention @davrous , cheers :)

P.S :  I tried to upload it, however due to my apple and snake are in different files than babylon javascript file, somehow i cant reproduce the snake nor apple image object in playground. Therefore, the program wont run in playground :)
