WebSockets and WebGL used to create multiplayer shoot'em up

Neat! Would love to know how you handle prediction and correction.

My last ludum dare was webgl+websockets, but because I used server lockstep (it being a 72hr game and coded from scratch) it was pretty poorly received :/

Runs pretty smooth and the multiplayer seems to work fine (though Quick Play dropped me into an empty game the first time). Giving the bullets a black outline is a good move because I cannot make sense of the rest of the visuals - horribly low contrast and super noisy, almost random use of color.

Seems to play pretty well other than the issues created by the indecipherable visuals though. I think multiplayer makes this kind of game more engaging, but you need to take steps to overcome the visual confusion and tendency to be overwhelmed when there are 4 players worth of bullets and special effects flying around the screen.

I agree about the visuals. I also found the WASD movement, arrow keys to fire scheme pretty hard to use. Can you use the mouse to fire?

Yes.

Yeah visuals are confusing, here is how I would fix it:

Make each players view of the game unique such that it is easiest to decipher where their ship is, and where incoming bullets are. So the player's ship could be bright white, the harmfull bullets bright red or orange, and everything else a darker color. What the next player sees is different - a view designed to distinguish their own ship, and player 1's ship is dark. Make sense?

Thanks for the ideas and thoughts, I'll link the team to this post :)

Please don't, isn't the whole idea of geometry wars that the difficulty comes from the visual chaos?

If everything was super clear the whole challenge of the game would be reduced..

Damn pretty great, I played a Geometry Wars game together with some other people, no lag, no glitches the entire game. And a whole bunch of nice animations and effects.

This shows that at least for the arcade market, the web really has become a mature platform. Ofcourse, this game was cooperative, and chaos-y. It's not certain at all this kan be made feasible for competitive multiplayer with more strict rules.

Maybe that just means it's restricted to fun games ;)

The small print (http://biz.turbulenz.com/developers):

So they're going for an app store model by using a free API as bait.

You can use an Xbox 360 gamepad if you've got one lying about :)

Didn't seem to work for me in Chrome, but did work in Chrome Canary.

You might have to enable a setting in chrome://flags in normal Chrome.

This is cool and it works well.

However the graphics are giving me a headache. I played for 10 minutes and I quickly couldn't find my mouse's cursor, nor distinguish between enemies and the background, enemies and the rewards, and enemies from myself. Too many colors.

Not quite Ikaruga level yet, but quite impressive and the gameplay is good. It could feel almost like a whole new game with re-done artwork.

It was fun, but sometimes _really_ hard to determine if I was actually participating in the game or just spectating!

Great fun! I registered for an account, but then stopped being able to play multiplayer games. Maybe I'm just missing it, but there "quickplay" button that I was using as a guest is no longer there.

Make sure you're playing "Score Rush MP" which is the multiplayer version. You might have accidentally started the original single player version. Select the game from the "Games" dropbox in the top right of the website.

Thanks, that fixed it.

The usability is awful. Too many graphics blend in together and the hot key choices are confusing.

However it's ridiculously smooth and ran great on a ~5 year old machine. The controls felt excellent.

Is there a youtube video?

I found this http://www.youtube.com/watch?v=NDGl-eDEuNQ but I'm not sure if its the same game.

Not sure what was doing, but it was kind of fun. What I'm really hoping for now is multi-player pong (with up to 32 rotating pong bats).

I played with some of the effects tunned down and it was less chaotic. Great game.

Is there a technical reason for not using webgl frameworks such as Three.js ?

The game uses the Turbulenz Engine which includes a WebGL graphics framework (which is equivalent to Three.js) - http://biz.turbulenz.com/developers#turbulenz-engine

Doesn't work in Firefox

We're on Hacker News. Couldn't you at least try to give a meaningful description of what doesn't work?

I'm seeing just a blue to white vertical gradient, so I'd hazard a guess that the whole thing isn't working. (And yes, WebGL is working.)

If you've got a moment it'd be good to know your configuration. My default answer is to recommend Chrome, but all versions of Firefox are supported (for those without WebGL support we provide a small plugin as an alternative).

Seems like it was blocked by AdBlock. Disabling itresolved the issue

Actually, now I can see the menu, but neither "quick play" nor "create game" work. Says "Something has gone wrong - please try again". Firefox 16.02 on Windows 7.

Music is great though :)

I was finally able to play it, and one issue I noticed was that the sound becomes choppy when there are a lot of projectiles on the screen (which is, all the time :))

Just played it on ff 16.0.2 no problem.

Impressive. This is the most fun HTML5 games that I played.

Nice, I've been looking forward to seeing games like this.

This. Is. Awesome.

Great but the action is a bit too chaotic , to much things on screen. I suggest reducing the sprite sizes a bit , and make the background less distracting.
