Gravatars & Comment Links

I’ve changed a few things about the comments around here.

The regular WordPress policy is to put a “nofollow” tag on the comments so that search engines will not give “credit” to the website of the person who left the comment. The idea is to take away a lot of the incentive for spamming comments. It happens anyway, but at least the process is made less rewarding for the spammer. In theory.

But this means treating all commenters like spammers, which I dislike. In any case, it’s a needless policy on my site, since my anti-spam measures block 99.99% of it, and I manually delete the rest. The upshot is that I don’t have spam comments, and so treating all commenters like spammers because some of them might be spammers is silly. So, I turned off the “nofollow” thing. This means that if you leave a comment and provide the URL to your website, you will get “credit” for the link.

The other thing I did this weekend was add support for Gravatars.

I saw Gravatars in action in the comments at Terminally Incoherent, and thought it looked really cool. Long threads can get confusing when you’re trying to keep track of who said what. I’ve found I remember “faces” better than names (even if the faces are just abstract icons or logos or whatever) and so when everyone has their own icon I find the whole thing easier to follow.

This is one of those things I’ve been waiting for someone to invent. I hate how you can’t have personalized icons when you comment at a blog, and I hate uploading the same user icon every time I join a new forum. Gravatar can, in theory, solve both problems. Once you set up a Gravatar it then becomes a “portable” avatar that you can take with you to other websites and forums – provided they support Gravatars. If you change your Gravatar, you don’t have to go to a half dozen different sites and make the change manually. It just happens.

It sounded really cool. It was very easy to code. It’s based on email, so (in theory) if a user has a Gravatar all they need to do is supply the email address when they leave a comment, and their avatar icon will show up.

Sadly, after setting it up and putting it into place I realized that nobody uses it. At least, nobody around here. I checked some of the old comment threads (from back in the days when I used to get 100+ comments) and not a single avatar showed up. Sigh.

I’ve left Gravatar support in place to see if it catches on. We’ll see.

 


 

Half-Life 2 Episode 2: Riding Shotgun

The chapter begins with the player and Alyx traveling on the open road in their newly-acquired muscle car, heading for the White Forest base to meet up with the rest of the resistance.

I love driving the car, although the road is too serpentine to be able to hold the accelerator down, assuming you don’t want to be fighting for control and clipping the occasional rock or tree. You have to “flutter” it, tapping the gas a second at a time as you go. Ugh. In real life Alyx and Gordon would most likely be puking after a mile or so of that. Makes me wish for an analog throttle.

I love how vehicles in these games allow you to steer and look around independently. It’s nice to begin looking left before you start turning left, instead of having your eyes locked in a forward-looking position. It makes the vehicle easier to use and allows you to drive the car the way you would in real life. This gives driving an incredible degree of realism, and makes it more satisfying to drive than doing so in games which are expressly designed for driving. (Although, it makes me wish for analog steering. I realize there isn’t really any way to have analog throttle, steering, and looking in any existing control scheme, but that doesn’t stop me from wishing for it.)

Our first stop along the way is the radio tower. Alyx decides to send a message ahead to White Forest base and let them know the Combine are coming. We have to search the abandoned buildings to get the power back on and send our message. This is another thing I love about this series: Other games would tuck a few foes into these buildings and call it a day, but instead Valve lets the player explore the space first. Quiet exploration is nice and lets us take in the scene visually instead of blasting our way through it, but it also helps to build some tension.

And in the basement of the power station we finally encounter an interesting plug puzzle. Plugs have been a feature of the game since Half-Life 2, but the “puzzles” have always been mind-numbingly simple. You either: 1) Plug in the thing that needs power or 2) Unplug the thing you want to turn off. Not exactly a source of mental stimulation, there. A Rubik’s Cube this ain’t.

But here we have a honest-to-goodness puzzle. Like a lot of the best puzzles in the game it’s not long or difficult, but it’s a real puzzle and provides a nice break in the fighting that satisfies my puzzle drive.

Once completed, we’re ambushed by hunters. Here Alyx’s character really shines. Last time she faced one it nearly killed her. (Actually, given the things the Vorts said, it sounds like it did kill her.) Now she has to face them again. We’ve never seen her this frightened before. She’s terrified and angry over her last encounter with one. She starts off in a mild panic, but as she realizes the fight is inevitable she masters her fear and readies herself for the battle. As you bring down the first one you can hear the relief in her voice. We can beat these things. It’s a real turning point for her and wonderfully acted. There are many big-budget movies that fail to handle moments like this with as much finesse.

It really is shocking how much better Valve is at creating characters than everyone else. It’s been a few years since Half-Life 2, and still nobody else is really anywhere near them in terms of having lifelike, believable NPC’s that can accompany the player and perform in a dynamic situation. Everyone else has to stop the action for a cutscene, and even then their characters usually aren’t as expressive or as well acted as Alyx Vance. It’s amazing how far ahead they are.

The hunters are interesting foes. They are pretty good at flushing you out and flanking you. They are probably the most interesting foe so far.

We put down the hunters, send our message to White Forest, and then hit the road.

The encounter with the advisor is pretty interesting, although, like most encounters with these guys, it satisfies our visual curiosity without actually telling us anything. Once the advisor flees and we blast our way out of the farmhouse, we find ourselves driving for our lives while a helicopter runs us down.

I wish that somewhere along the trip we had a nice stretch where we could really work the car up to top speed and enjoy a bit of driving on the open road. Most of the trip is spent on navigating winding dirt roads and hairpin cutbacks, or dodging wrecked vehicles. The only place where we could really push it is during this helicopter chase, and here you have to keep swerving and changing speed to avoid bombs.

We reach the outpost and stop to fight the chopper. It took me an embarrassing amount of time to figure out what I was supposed to do. I saw other rebels had rocket launchers (which never seemed to hurt the chopper, for some reason) and I thought I was supposed to get one for myself. Did I miss it? Is there one lying around here that I’ve overlooked? Am I supposed to wait for one of these idiots to snuff it so I can have his? Once I figured it out it was one of those forehead-slapping moments.

 


 

Image-Metrics

This is amazing. I almost didn’t link it because you have to visit the site to see it. They really need to think about making that into a YouTube video.

The demo on that site shows a woman making various expressions and faces for the camera, while a computer-generated face does an exceptional job of imitating her. The actual geometry of the face isn’t all that impressive. (It looks very plastic and lifeless. Haven’t these guys heard of texture maps? Then again, maybe the model is made this way on purpose, so that you focus on the motion and not the shape of the face.) The animation goes a long way to bringing the face to life, although I can’t help but wonder how it would look with a more convincing 3d model.

The obvious application here (and what they seem to be selling) is a system for making complex facial animations with minimal work. Doing this stuff by hand is a chore, and tends to look very mechanical. (I’ve dabbled with it. It sucks, and it takes a huge investment of time and skill to get rid of the mechanical feel.) Doing it “right” involves an actor putting on special makeup (usually dots all over their face for the computer to track) or other tricks to give the computer well-defined points of reference. But the system shown here seems to let anyone sit down in front of the camera and start mugging without any fancy setup.

I’m willing to bet it isn’t realtime, even though the demo movie seems designed to allow you to think so. I’m guessing you capture the video and then the software needs a jolly good think before you can see the results in action. I’m also confident that it would have trouble if you spoke. I doubt it attempts to track anything inside the mouth. Near the end of the demo the actress licks her lips, and the avatar doesn’t. It’s possible that the avatar doesn’t have a tongue, but I think it’s more likely that the software can’t quite comprehend tongues yet. This is a shame, since if that worked this would be the ultimate way to make lip synch look good. Just get a video of your voice actors as they do their thing. Most voice actors already emote visually when they do their thing, so the extra data would be “free”.

At any rate: It’s fun to watch the animation do its thing.

 


 

Half-Life 2 Episode 2: Freeman Pontifex

The opening of this chapter begins with Gordon, Alyx, and Cecil emerging from the mines to a stunning vista of the huge combine force crossing a bridge in the distance. They carry advisors. Cecil tantalizes us with his knowledge of them but doesn’t actually tell us anything.

Alyx’s gradual revival from the near-fatal hunter wound is convincingly portrayed in the next scene. She doesn’t recover instantly, but she also isn’t a limping hindrance as the story moves along. She recovers slowly over the next half hour of gameplay. Continue reading ⟩⟩ “Half-Life 2 Episode 2: Freeman Pontifex”

 


 

Voice of Alyx Vance and Dr. Kliener

Despite my unwitting appearance on Attack of the Show, I’m not a huge fan of G4tv. I see clips of it once in a while on YouTube, and the hosts always seem like they need to cut way, way back on the caffeine. Having said that, once in a while I see something that really captures my interest. Here is a good example:

I found this while searching for Half-Life 2 gameplay videos. (Which I’ve been watching for reasons I can’t even begin to explain.) It’s Hal Robins and Merle Dandridge, who play Dr. Kliener and Alyx Vance from Half-Life 2. (Merle phones into the show so you can’t see her, but if you want to see what she looks like you can do so at her official website. You can see her in an interview relating to her Broadway work here.) As the hosts point out, it’s really strange hearing these familiar voices coming from unfamiliar faces.

I was also surprised at how much Hal Robins looked like Jerry Holkins of Penny Arcade.

 


 

Half-Life 2 Episode 2: This Vortal Coil

Someone commented that my previous post seemed a little nit-picky. That’s a natural part of what I do when I love a game, is to pick it apart and see what worked and what didn’t. Just so nobody gets confused and thinks I have a problem with the game: This was tremendous fun. I want to make it clear that the gripes are a bit of armchair game development on my part. It can’t be helped, really. Anyway, onward…

hl2ep2_vortal_coil1.jpg
As you drop into chapter 2, you meet Griggs and Sheckley. I don’t know what these guys are doing down here. The only route to the surface is the broken elevator. I’d assume they lived here with the Vorts, but they seem genuinely surprised to see the Vorts when they show up, and their banter makes it sound like neither one of them has seen Vorts fight before. There doesn’t seem to be any living space nearby, or any sort of food. As far as I can tell, the turrets and tunnels are set up so that they can live here and take care of the turrets and tunnels.

What are you idiots doing here? How did you get here? Where do your supplies come from? Curse Valve software for making Gordon mute so that I cannot ask these all-important questions!

Top 50 RPG Websites

By Shamus Posted Wednesday Dec 5, 2007

Chainmail Bikini made #12 in this list of Top 50 RPG websites over at Dungeon Mastering. Sadly, Shawn and I were just edged out of the #11 spot by the no-talent hackjob rival comic DM of the Rings.

I’m currently playing in a D&D 3.5 campaign, as opposed to going to all the trouble of running one. This has made me very lazy, so I’m not reading many roleplaying sites these days. When the pendulum swings back to my chair I’ll start reading again. Probably with some sort of anxiety. I was happy to see Treasure Tables and Chatty DM both placed high on the list. I enjoy both sites, and as we all know “Top X” lists like this one only exist to make us feel good about choices we’ve already made.

Anyway. Number twelve. Yay.
