    There's a mistake at 13:20. That should obviously be this.position.x += 5 * deltaTime;

    When I try to load the black box, I get this message in my console:
    GET file:///C:/Users/13159/Documents/FreeCodeRPG/src/rpg.js net::ERR_FILE_NOT_FOUND

    For the ones having difficulty displaying the paddle. use
    <script type ="module" src = "index.js"></script>
    and
    import Paddle from "/paddle.js";
    instead of the codes provided in the video.

    import Paddle from '/src/paddle'

    "Uncaught SyntaxError: Cannot use import statement outside a module" – any idea how to resolve this error?

    My version is not responding to the collision on the sides of the object. So when the ball hits the left/right side of either paddle or bricks the ball is not bouncing. Has this happened to someone else too? any idea what could be causing it? I am comparing my code with the one on the video and looks similar to mine.

    Guys if you want your paddle to move by mouse then just input this instead all of that code for left and right arrow key:

    cvs.addEventListener('mousemove', (event) => {

    paddle.position.x = event.offsetX;

    })

    Question: Why does having the if statements at 22:54 make the paddle not stutter?

    Why the timestamp in the function at 15:42 ? it is only a parameter, but never set equal to anything

    Also The Paddle's Not Coming To Center.

    Also instead of doing var use let it is better at assigning variables.

    Once I started doing the import export of the class Paddle, it wouldn't show the paddle on the screen. Not sure what to do

    Hi there, really awesome tutorial.
    Actually I found a bug:
    the ball can enter the blocks from the sides making weird zigzagging an destroying a lot of blocks.
    solution:
    in the collision detection file you have to add the ball size to the leftsideofobject comparison instead of the right. (line 13&14)

    The alerts while testing the input handler (the ones that say "move right" and "move left") keep coming nonstop after I press ok, even though I removed the alert line. Its like theres "ghost code" still executing. Any suggestions on how to fix this?
