XMLHttpRequest cannot load http://m.agar.io/?_=1430388662333 . No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin ' http://agar.io' is therefore not allowed access. The response had HTTP status code 520.

This is a nasty thing that's mostly the applications fault but I feel the browser could be a little more smart about it too. The issue is that CORS headers are usually set at the application level, and applications often forget to set them when catching an error. So if for instance your page makes a CORS request and the MySql server is away. Your app framework catches the error and renders the 500 message, but it doe…

Unfortunately, nginx doesn't allow you to set custom headers for error responses by default. You need to add something like the ngx_headers_more[1] plugin for that.

Why the decision to use C++ instead of NodeJS?

Probably speed.

Is it signifiant? I haven't even thought to lookup benchmarks.

Only sending input? That's great networking design!

Yeah I know right. No wonder this game crashes. When you press the space bar it sends a message, when you move your mouse it sends a message. The message is in function U() (its the Y position, X position and some other value I've confirmed its not magnitude don't really know what it does). As soon as the connection is established it starts sending, although if you don't move the mouse it doesn't send a message. Then…

How could you do better than that?

It's a real-time game; it needs that much input data (but nothing else).

Feature requests: choose the server (to play with friends), see map borders, super fast mode (twice the speed for everyone)

Great game!

Think that part of it is that only one process or thread can run at any given time in node. So, if you have a complicated multiplayer server, subroutines will start getting blocked.

After the MMO Asteroids incident [1], I had to switch off my network connection to reassure myself that it isn't fake. If you're looking for a more in-depth experience, check out Osmos [2], the single-player game that probably inspired this.

It doesn't appear your [1] MMO Asteroids link is correct. It's a comment about doing Cocoa dev for 10 years

Ah. https://news.ycombinator.com/item?id=3819638

Seems like there were no asteroids.
