Electric Potential Pong (html5/processing.js)

But I didn't expect it to work! According to the comment at http://news.ycombinator.com/item?id=3742893

"Just loading the vote URL directly or in an img/iframe wont work because votes that don't have a HN referrer don't get counted."

edit: the author of that comment has edited it to remove the part about img/iframe. It DOES work in an iframe in this case.

As of 146 points I have removed the code from the webpage and sincerely apologise for any confusion caused. Nonetheless, I hope that the bug gets fixed soon so that others won't exploit it to promote more malicious sites.

Attempted to take advantage.

Doesn't seem to have worked, or at least, I visited the link and it still shows the arrow unvoted.

Edit: Looks like he commented it out before I clicked. So I guess it did work.

Good point. I've tested and all the levels are beatable eventually, although some are quite long and difficult. The ball gains some speed with each hit, so eventually it will have the kinetic energy to overcome the potential and behave like classical Pong. If I create a more polished version of this, I will likely design the potentials manually; here I was rather lazy in making this proof-of-concept demo so I generated all the levels randomly.

processing.js is hardly indicative of HTML5 game performance in general. Also, if this code were to actually only redraw what needs to be redrawn (the paddles and ball), CPU usage would be near 0.

Looking at chrome's task manager, after just loading the page it's memory use grows from 60MB to 260MB before falling back to 60MB, repeating every 4-5 seconds. That seems a bit wasteful.

The ball is charged and resides in an [electric potential](http://en.wikipedia.org/wiki/Electric_potential).
