  1. Re:Fighting on Matrix Online Creators Quizzed On MMO Wire-Fu · · Score: 1

    So, let me try to understand your vision: Players are running around shooting each other in real time, but someone is engaged in a bullet-time battle, they are shown as being very slow. However, this won't affect the rest of the world?

    Anyone who can see into the bubble is part of the bubble, was what I meant. That's why I mentioned the rain; you have to constrain line-of-sight so the effect doesn't spread to the whole MMO world.

    Also, what if you're in a team? You have five characters (Team A) who encounter 5 other characters (Team B). Two opposing characters, one from each team, go into bullet-time.

    The players are all involved in the bubble. The players without bullet time enabled have slowed controls and move like they're stuck in mud. The characters with bullet time enabled move normally except that they appear less affected by gravity (9.8 ms-2 appears as 0.98ms-2 if one 'real' second is 0.1 'in-game' seconds)

    Alternatively, while the two players are in bullet time, you take your four team members and spray as much machine-gun fire into the bubble as possible...

    etc, etc - you've misunderstood. All players within sight of each other are affected by the bubble.

    your control is stopped immediately when someone pops into bullet time, then you've just given controllable lag to upper-level characters

    Yes, precisely (except that control is slowed, not stopped). What do you think bullet time is, but the ability for agents to avoid the lag of the real world? However, if you have any ability available, turning on your ability should be either automatic or instantaneous, not delayed as for normal motion.

    Then you have to determine what the affected radius of bullet time exposure is, whether it works through walls and windows, etc.

    You can have it purely line of sight, but that has obvious problems with 'infecting' the whole world with slowness, unless you prevent people forming a human chain of lines of sight to the original bubble.

    My preferred alternative would be to make the effect depend on your radial distance from a character in bullet time. In this case, yes, bullets from outside would slow as they neared the location of characters in bullet time; but if the radius of effect is large enough - say linearly decreasing to 100m - you still have plenty of time to see bullets coming.

    Putting some real figures on this - 500m/s muzzle velocity is realistic, 5m/s is dodgeable so 1/100 speed is agent-level. Fighting an agent at 1/100 speed would be unplayable, but then again, thats the point - as you get closer to his ability you get more able to fight them; and you're not a normal human so you'd be moving about 1/10 agent speed, not 1/100. Scaling the effect up to 100m from the person in bullet time so that v -> v/(1+f(100-r)), where f=1 (1/100 speed at centre) for an agent, the bullet takes 10s to hit from 100m. Putting f=0.5 (1/10 speed at centre, more like a good normal player) a bullet still takes 5s to hit from 100m. Even a spray of bullets from the edge of the bubble would be dodgeable.

    There are intrinsic problems with having multiple time scales in a multiplayer game, and those are a few of them. If they can pull it off, I will be very, very impressed.

    Indeed. But the problems aren't intractable. The biggest difficulty is making this a game worth playing; the console matrix game was totally crap, remember.

  2. Re:Fighting on Matrix Online Creators Quizzed On MMO Wire-Fu · · Score: 3, Interesting

    Its not /that/ hard to do. Here's how: you can have two kinds of bullet time, 'slow' time, where other characters get slowed down, and 'fast' time, where your character is speeded up.

    For 'slow' time, the effect is confined to a bubble, so you can have bullet time fights without affecting the whole world. As different characters are differently able to distort time, control speed and physics are changed by different amounts depending on your abilities; but all characters 'see' the bubble as if they were the fastest character (ie you see it the way the movie did).

    To avoid discontinuities, intra-world communication (eg speech, phone) with someone in a different timeframe is disrupted, but inter-world communication is unaffected (eg a 'find me an exit' conversation). Constant rain and other effects can be used to constrain line-of-sight so there are no visual discontinuities.

    'fast' time can be used for pre-planned actions, eg running along a route. Since you don't need real-time control, a fast character can then be moved at super-speed to their destination, and slow characters see an appropriate visual effect. Encountering a 'slow' bubble while moving along a 'fast' route drops you back into control.

    I'm sure this leads to plenty of temporal anomalies, but unless you give they characters wristwatches they won't be annoyingly obvious.

    But you think a command line would make using a digicam easier? A microwave? A thermostat?

    For 2 out of 3 of these, the answer is yes. I'd probably say yes to all 3 if I used a digicam more often.

    Hardware user interfaces are patentable (do a USPTO search for microwave control panel) and thus there is a small fee for including one developed elsewhere. For low-end consumer devices, with small margins, this introduces a disincentive to using the best user interface. As a result, microwave UIs are generally confusing. I often see people in our office push buttons semi-randomly to get the thing to start, then open the door to stop it when enough seconds have passed - they can't even operate the timer.

    Similarly, looking at the timed thermostat in my house, it uses little pushpins to determine on/off times, but its difficult to set the /current/ time, the power level doesn't relate to the temperature, and all the radiators have their own thermostat anyway. Its a mess.

    now apart from the nitpicking complaint that they should use example.com as the test domain (follow link to see why), its obvious that this needs client-side support. With browser rollouts being mindnumbingly s l o w, that means they are probably targeting web services, or non-browser clients, or must be building a browser extension?

    Secondly, the spec for the client request for a ticket doesnt include any authentication info whatsoever. Ok, this means they must be doing that in 'some other protocol' (presumably Jabber + SASL). They could be a bit clearer... this part basically requires you to have a fairly complete XMPP implementation in order to get at the apparently simple ticket service.

    Mark me down as unconvinced. Take a look at Shibboleth and OpenSAML to see what others are doing in this space - they are already doing single sign on, and it already works (OpenSAML does have the downside of being affected by a free-to-license RSA patent).

  12. Misleading statistics. on Designing Websites - What Browser to Code For? · · Score: 3, Interesting

    Just to repeat what everyone else says first: its very important to design to standards. Its the only way to be sure that things will continue to work.

    But a second point: many browser statistics are misleading. As well as it being easier for non-IE users to block webbugs and fake user-agent strings, sites that are designed for IE only suck in other browsers, and arent 'sticky' for non IE users. Non IE users will be consistently under-reported on many sites as a consequence.

    So, if there are 10% of users using non-IE, and you are only getting half of them, should you care? Well, yes. Non-IE users are more likely to be technically savvy - they've got as far as changing their browser!.. and are thus more likely to be educated, employed and able to pay for stuff (especially small shiny expensive stuff). So you lost 50% of one of the best market sectors, while keeping 100% of the deadbeats. Nice move.

    Knowing your market sector is more important than knowing what your browser shares have been. E.g. we work in on sites which are largely browsed by architects, and guess what - they largely use Macs. But we didn't get them until we spent time making the site Mac friendly.

    Part of the problem here is that there isn't enough mindshare for the idea that the format you edit in isn't the format you share files in. MS are at least indirectly to blame here, their monopolistic status has given people the impression that MS Office formats are appropriate formats to share documents.

    In the UK govt software market, people who make systems to support the Public Records Office standard - for archiving, ie sharing documents with our future selves - must support storing the original document, AND a 'rendered' copy that will still be legible in future.

    Looking at them from this archival viewpoint, it becomes obvious that MS Office formats are inappropriate for rendered/interchange usage, as OLE containers can contain pretty much anything - you need every windows program on the planet to be sure you can read them. Not only that, they often preserve editing/versioning information which you don't want to share (see eg. the leaked origins of the UK WMD Dossier).

    I don't expect things to change anytime soon, theres no money in it; and none of the available options are all that great (PDF also has plugins, PS isnt supported well in windows, XML can contain arbitrary meaningless binary data, etc).
