Physics Engine

When I do the “ask me a question” things, I generally stick to questions I can actually answer. But in this case I think what the curious person is looking for is a rough overview, not a detailed white paper. This being the case, I think I can help. As always, remember that my understanding is probably a few years out of date.

Reader Kronski asks:

I don't know if you've seen this video.

It's demonstration of a physics engine where a truck gets banged up all to hell. My question is, how does a physics engine like this work?

So you don’t have to head over to YouTube, the video in question is this one:

The basics of a physics engine are easy to grasp. The finer details are beyond me. Let’s start with the essentials. You can see the ultimate demonstration of basic physics at work in the bridge builder game.

The idea is pretty simple: It’s a simulation of points in space. You have a bunch of points and you subject them to gravity and collision. The trick is that you link the points together. Let me swipe a screen shot from the bridge game:

Alan Wake EP26: The End

As I said in the ending credits, I think Alan Wake had all the ingredients to make a much stronger game, and most of the major systemic flaws were a result of a few key mistakes. Here is what I’d do to re-edit the game:

Saints Row The Third: Part 1

Like I said, Saints Row The Third is really great, but not perfect. So let’s talk about the bad parts, the odd parts, and the stuff that was left out. I had originally titled this series “Saints Row Nitpicks”, but as I wrote it grew from an enumeration of shortcomings to a more general discussion of the game and the genre it inhabits.

For the record, I didn’t play the first Saints Row game. I know nothing about it, except that it was notoriously buggy. For me the series began at Saints Row 2. I’ve played through the third installment once now, and I’m currently working on a semi-completionist second run.

You may notice that the player character is different in some of these screenshots. I tend to re-invent my character every couple of hours, changing my gender, race, voice, outfit, etc. (You can change all of this at any time. The character builder is just another store in the game. Going from a tiny female waif to a burly bearded muscleman is no different than buying a new shirt.) It’s a bit schizophrenic, but I like hearing all the different versions of the main character’s voice. And if you promise not to tell anyone, I’ll admit that I enjoy playing dress-up with my avatar.

A final warning: Spoilers ahead. I mean, this game is really, really obvious and I sort of balk at the notion that any of this could spoil the game for you, but I understand it’s considered rude not to give fair warning.

Yes, the show is turning into a podcast with accompanying unrelated videogame footage. We just don’t have a lot left to say about Alan Wake. There’s about 40 minutes of footage left. I don’t know if Josh will break that into one episode or two. Either way, we’ll be wrapping things up this week.

We discussed The Stanley Parable in this episode. It’s a source mod game. You can get it for free here.

I’m sure you’ve noticed the thin gruel that’s been passing for content around here lately. If it wasn’t for Spoiler Warning this place would have been a ghost town last week. This is why. I’ve been playing Saints Row the Third.

I did a series a few years ago where I compared Saints Row 2 with GTA IV. Now I want to do the same thing with Saints Row 3 and compare it to… everything else.

Alan Wake EP24: The Beginning of the End…

Man, it sure does suck that Shamus inexplicably forgot to post this yesterday. Because there’s no way I got sick and only got around to editing it this morning. Nope. Nothing like that happened.

And even if I did somehow get sick, I’m sure it’s all Shamus’ fault somehow. It’s more fun that way.

 


 

Alan Wake EP23: Swan Dive!

This late episode has been brought to you by Saint’s Row The Third and what the heck is it seven o’clock already how long have I been playing this game?!? I should probably do a post about that game. It’s sort of come and gone, news-wise, but it’s some of the most fun I’ve had in ages.

I just want to reiterate what we said in today’s episode: Alan Wake is not a horrible game, and our criticism of it is the result of a game that did a lot of things different, took a lot of chances, got a few things right, and missed on a couple of crucial points. I’m sure I’ll never play through it again, but I don’t begrudge the hours I spent with it. Well, maybe a few of them. The ones in the middle.

Swan dive!
