Open world level design: spatial composition and flow in Breath of the Wild

So, like much of game dev Twitter, I too saw Matt Walker's Twitter thread that summarized a CEDEC 2017 talk on how Nintendo built the game world in The Legend of Zelda: Breath of the Wild.

If you're not familiar, Breath of the Wild is highly-regarded as a return to good game design within the Zelda series -- if you want to know more about how the various game systems or simulations work, you should check out their GDC 2017 talk, where they emphasize an emergent physics / problem-solving perspective with the general game design.

But Walker's thread caught my eye (and everyone's eye!) because it was about something more basic and fundamental, which is composition of 3D worlds. The development team came up with a great memorable typology / design grammar for their vision of open world level design, and I want to recap it before Walker's tweets get lost in an unsearchable Twitter soup.

Again, I didn't really write this stuff or come up with these insights, but seeing as this is sort of a level design blog, I feel it's important to archive this stuff for all history, etc...

Adventures in VR sculpting

I've been sculpting a lot in VR lately (via Oculus Medium) trying to figure out whether it's "the future" or not.

While I've worked in 3D for a long time, I'm used to building levels in a low polygon style with a 2D interface -- so for me, working "natively" in 3D VR has been strange and confusing, as I try to figure out how sculpting workflows work with 3D motion control interfaces.

When you are 3D modeling in a 2D interface, you can only move in two dimensions at once for every operation. Every stroke is constrained to 2 directions, so you learn to limit how much "each stroke" is supposed to accomplish. You begin seeing 3D in a specific "2D" kind of way. A lot of existing modeling software has evolved to fit this workflow, using operational systems that are non-linear and asynchronous -- what I mean is that each time you move a vertex or apply a bevel in Maya, you can always tweak or adjust that action later. Need to twist a tentacle in a weird way? You setup a spline, and 10 clicks later, you have a twist. It's very accurate because you're working very methodically in super super slow motion, decompressing time.

Current VR sculpting software doesn't really capture this "bullet time" dimension of working in 3D. Instead, it's very immediate and continuous. It's unclear whether VR will ever be able to support the high text density / menu complexity that most 3D modeling software needs.

If you have shaky inexperienced hands, too bad! You can't fine-tune or adjust your tool movements after you perform them, you just have to get better at doing more fluid, cleaner hand gestures.

Before, with a mouse, I could sort of do 100 different strokes and take the best bits of each one, and assemble the perfect stroke. But in VR, I feel like I can't do 100 takes, I get only 1 take, and I better not fuck it up! (Ugh. Why is this "natural" interface supposed to be so much better? Fuck nature!)

So now I basically have to become a much better fine artist, and learn how to move my body around the sculpture, instead of simply trying to developing the eye of a fine artist. Some of this frustration is due to the difference between a sculpting workflow vs a polygon workflow, but the inability to rest a mouse on a table certainly exacerbates it.

It also probably doesn't help that I'm taking on one of the most difficult topics of visual study possible, a human head. It's very easy to sculpt a "wrong-looking" blobby sculpture, as you can see in my screenshots! Fine artists usually spend many years in figure drawing workshops to train themselves how to "see" people and understand the many different shapes of our bones and muscles.

But I think this challenge has been helpful, and it keeps me focused on figuring out which skills I need to develop. How do I get clean sharp edges and defined planes in VR? Should I sculpt with blobby spheres and flatten it out afterwards, or should I sculpt with flat cubes and build-up my planes from the beginning? I'm still trying to figure it all out.

And if VR sculpting truly is the future, I do wonder how this will factor into a game development workflow. Maybe we'll sculpt basic forms in VR, and then bring them into Maya for fine-tuning -- or maybe it makes more sense the other way, to make basic forms in Maya, and then use VR only for detail?

I don't know of any game artists who seriously use VR as part of their workflow, but if you know of any, let me know so I can figure out what they're doing and copy it!!

(And hopefully in another month, my sculpts won't be so scary...)

Writing stories / dialogue for Unity games with Yarn

I've been using Yarn for a little while, and I've grown to prefer it as my "talking to NPCs" solution for game development. If you're not familiar, Yarn and Yarn Spinner are a pretty powerful Twine-like plugin for Unity (though it could technically work in any C# game engine) that's geared towards writing video game dialogue, and it was most famously used for Night In The Woods.

Yarn is fairly lightweight, extensible, and it basically gets out of your way. Want to make a really big long monologue, or 100 little pieces of dialogue snippets? Yarn works well for both of those use-cases. (If you want something that's more focused on manipulating very long dense passages of text, you might want something more like inkle/ink, the system that powers the huge 750,000 word narrative game 80 Days.)

To try to provide more resources for other Yarn users, or potential Yarn users, here's a write-up with some advice and a short guide to working with Yarn...

"Gay Science" at NYU Game Center, September 28, 2017 @ 7 PM

if you look very closely, you'll notice Nietzsche's moustache / hair / ears are actually made of tiny gay people writhing around, having a bunch of hot writhing techno-sex? poster by James Harvey

In about 10 days, I'm giving a talk about games at NYU Game Center called "Gay Science." Here's the blurb:

Robert Yang is a game designer and teacher who is the most recent addition to the Game Center’s full-time faculty. For the past few years Robert has been doing groundbreaking work as an indie developer who appropriates the tools and techniques of mainstream big budget videogames to make work that is personal, idiosyncratic, and highly experimental. His recent games exploring queer sexuality are powerful and sometimes scandalous interventions in gaming culture and he has developed a creative practice that crosses wires between the world of avant-garde media art and mainstream youtube streamers.

In addition to his creative work Robert has developed a large audience for his work as a game critic and thinker across a wide range of topics including an especially deep exploration into the formal and expressive dimensions of 3D level design.

Join us to hear Robert talk about his work and share his unique approach to games, art, and life.

Free and open to the public.

I'm also sharing this Fall 2017 Lecture Series schedule with designer of "Everything" / artist David O'Reilly (on October 26) as well as industry veteran / Campo Santo artist for "Firewatch" Jane Ng (on November 30).

If you'll be around New York City, come on down! Please RSVP here so we know how many chairs to setup.

Level With Me, Half-Life 2, complete!

I've just finished playing through all of Half-Life 2 on my level design streaming show, Level With Me. Much like with my playthrough of Half-Life 1, I've played through this sequel several times already, and I thought I knew it pretty well -- but there were still sequences where I was surprised, impressed, or disappointed.

There were several main themes throughout this playthrough:

1. The current version of Half-Life 2, the only one now available on Steam, has been poorly updated and maintained. When Valve added HDR lighting to Source Engine 1, someone dutifully went through Half-Life 2 and updated all the maps -- but that process only involved recompiling the maps with HDR lighting. That broke several things: there are no LDR lightmaps (it's impossible to play Half-Life 2 without HDR now), and the unchanged settings are poorly calibrated for HDR, often being too bright / too dark / with lots of halo-y hotspots everywhere. If you want to play a better version of Half-Life 2, I recommend the Half-Life 2 Update mod, which fixes a lot of these issues.

2. Another frequent theme has been how Half-Life 2 keeps mixing itself up; one chapter is a horror survival segment, and then 2 minutes later the next chapter is a road trip driving section. This is pretty unusual in 2017, where AAA action games usually feel more consistent, systemic, and homogeneous. (Of the big franchises, maybe only Call of Duty maintains this roller coaster setpiece structure.) You could argue that Half-Life 2 sort of tries to do 10 different things, and doesn't really excel at any of them. Or on the flip-side, maybe the Valve of 2000-2004 was really impatient and bursting with ideas, and in the end, executes all of these ideas decently enough.

3. Rugs!!!

How to Graybox / Blockout a 3D Video Game Level

from de_crown, by FMPONE and Volcano

UPDATE, 11 NOVEMBER 2021: this blog post is OK, but I would recommend reading the "Blockout" page in my free online work-in-progress level design book instead.

ORIGINAL POST:

While planning a level design class, I googled for a good article about blocking-out or grayboxing a 3D level design prototype. I didn't really find one that actually went into "how" you might actually go about grayboxing a level, so I guess I have to write it.

Grayboxing is a level design practice where you build a rough block-out version of your level using blocks (usually gray boxes) so that you can iterate and test the layout as soon as possible. Almost every 3D game engine has some sort of box primitive tool -- if you know how to use that, then you can graybox.

Before you graybox, you must make sure you've established a general game design direction. You should generally know how this level might fit into your game or workflow. There's no point in grayboxing if you don't even know what the player should be doing, or what this level is supposed to convey. Is the level supposed to be easy or hard? Does it focus on combat or non-combat? Should it feel scary or safe? Level design must always exist in the context of a larger game design, or else you're just wasting your time.

Then, open up your 3D game engine, and let's start laying down some boxes...

On "Tacoma" by The Fullbright Company

This post spoils some of Tacoma and Sleep No More.

Tacoma is a sensible design progression from Gone Home. How do you expand upon the audio diary design and walking mechanics? The Fullbright Company decided to pair a dynamic holographic drama with some zero gravity movement. Unfortunately, the zero-G movement ended up making environmental storytelling more difficult so they had to scale it back (no tables or chairs; no objects at rest) and I also suspect it risked alienating a fan base that cares less about gamer-y traversal puzzles. So, that leaves all the focus on the holographic drama sequences.

Many commentators describe Tacoma as a virtual adaptation of the NYC immersive theater installation "Sleep No More" because both experiences involve wandering around a large dense environment and encountering short dramatic scenes of characters performing with each other... and then the characters split-off and you have to choose who to follow and listen to.

I think this is a telling comparison, because it also suggests the ways in which Tacoma's formal narrative structure doesn't work very well, despite its compelling themes and characters.

How To Tell A Story With A Video Game (even if you don't make or play games)

This post is a summary of a talk I gave at Storycode NYC on August 22nd, 2017. All the slides are available here. It is a primer for storytelling in games, intended for people who aren't gamers or game developers, but who want to get into interactive storytelling / immersive storytelling (like VR / AR / etc).

Video game design has much to offer interactive designers, even if you don't make or play any video games. When I taught at Parsons, we taught game design as part of our general design / technology curriculum, because this field has been thinking about the aesthetics of digital interaction for literally decades.

So if we want to tell a story with a video game, we should first ask, what is a video game made of? Some men have opinions on this:

Famous game designer Sid Meier has a famous quote: "a game is a series of interesting choices." When we play games, we're constantly making choices and feeding input into the game -- which way should Pac-Man go, how far should Mario jump? Some designers even treat the lack of input as an input. Inaction as an action.

My boss / NYU Game Center director Frank Lantz has a slightly less famous, but much more handsome quote: "a game is an opera made out of bridges." What he means is that a video games often try to present a sort of audio / visual "total work of art" spectacle that demands your complete attention and immersion, but to achieve that bombastic effect we also have to engineer physics simulations and future-proof code bases to work for many years. And if we're going to go with a bridge metaphor, we should also ask, what are these "bricks" and building blocks that make up video games?

On the hopeful undead future of VR and "A Short History of the Gaze", by Paolo Pedercini / Molleindustria

I played Paolo Pedercini's first (and maybe last?) virtual reality piece "A Short History of the Gaze" last year at Weird Reality. I think ASHOTG is good for a lot of reasons, but the foremost reason is that few people are making VR art that's critical about VR culture and its politics. The closest we get to is when we twist VR's (faltering?) utopian branding toward our own ends, whether for "empathy machines" or whether for a vision of a "gay VR". But even among artists, it's rare to see VR work that directly critiques what VR is about, in this current moment.

Like a lot of Paolo's other work, it's political and educational, trying to distill critical theory and media studies into a short accessible interactive experience. The player goes on a ~15 minute sequence of different scenes about looking at stuff -- undressing people in an elevator (male gaze), punishing prisoners in a panopticon (incarceral gaze), being trapped by advertising (capitalist gaze), etc. in various situations. I actually found the whole piece to be slightly encouraging, because it positions VR as part of a long tradition of gazes -- and it's also clearly the weakest gaze. If VR is an oppressive force, then that force is currently minuscule or even laughable compared to any other oppressive force in the world.

Which leads us into how VR is doing right now: it doesn't look good for VR.

Road trip sketches; notes on extracting and visualizing Half-Life 2 levels in Maya

So I'm working on (another) article about level design in Half-Life 2. I chose the d2_coast03 map of the Highway 17 chapter, which is the first real "coastline" road trip section of the game, and is probably the most successful. Look at how big and open it is. Would you believe this is a map in a game celebrated as a meticulous roller-coaster? In my mind, it's contemporary with a lot of vehicle-based first-person open world game design trends that started around the same time in 2004, and they even pulled it off in an engine architecture that's still kinda based on Quake 1.

Teaching, Fall 2017

As mentioned before, I'm going full-time with NYU Game Center starting this September. For this upcoming fall semester, I'm going to be teaching three classes and advising an independent study:

• Intermediate Game Development (2 sections). This is a required class for the BFA Game Design major where we focus on using Unity in a 3D context, refine C# code fluency, learn about using Maya and Substance Painter, and become less scared of using Git.
  
  This is my fourth year of teaching it. This year, I've changed the final project to focus on studying and cloning a game. In the past, the final project asked students to collaboratively formulate an original game design concept, but I noticed students would get into endless debates about the game design instead of focusing on project architecture or collaboration workflows. Since we already have dedicated game design classes that offer more support for those debates, I now feel comfortable removing some creative freedom from this class -- so we can focus more on building-up "technical freedom."
• Intro to VR. This is a new VR-focused class we're running for undergraduates and/or people who aren't so familiar with code and 3D. At Game Center we remain cautious about investing too much in something still fundamentally unproven like VR / AR, but we still want to support students who want to explore it. Unlike our graduate-level VR Studio class which assumes technical proficiency in code and Unity, this class will offer more of a scaffold into working in 3D and VR. We'll also dip our toes into talking about VR culture and critical theory as usual, but probably stop short of discussing Baudrillard and phenomenology.
• Level Design (independent study). Years ago I used to teach a modding class with a level design focus, but one day I noticed students hated using the Source Engine, and we never identified another decent engine / toolset for level design. We also needed a good base game to design more levels for, which is why we can't switch to Source Engine 2 -- DOTA2 isn't exactly relevant for learning generalized level design practices. At least half of our students also use Macbooks, which basically wither and die under Unreal 4, so that's out of our reach too.
  
  But then a few months ago, some students approached me to advise an independent study on level design. This format is more like a seminar / reading group instead of a full production-oriented studio class, and we will focus more on theory than construction. Hopefully this will work out better than the Source modding class!

StoryCode August 2017 Forum at Film Society, Lincoln Center, NYC

Next week on August 22nd, I'll be giving a presentation for StoryCode, a local community group focused on immersive media and storytelling technology. As one of the few game designers invited to present in their lecture series, I thought I'd try to explain how video games conceptualize narrative, interaction, and expression, to an audience that maybe doesn't play that many video games -- or at least, they don't play what we consider to be the state-of-the-art narrative games.

I'm also being required to talk about my games and present them as case studies, even though my games don't fit neatly into the "narrative game" genre. I think I'll probably just open my actual project scenes in the Unity editor and mess with my scene setup and code, which usually entertains people well-enough? It'll also be a short primer in foundational ideas like immersive fallacy / procedural rhetoric / platform studies, and the idea that production value and paratext amount to their own kind of "story."

The presentation is free and open to the public, but I believe you're encouraged to sign-up and RSVP via this Meetup page or something.

Go West young Slime Rancher, and grow up with the country

This post spoils some mechanics and game systems in Slime Rancher.

One in-game day in Slime Rancher, I found a rare "quantum slime", a creature that pooped out "quantum plorts" that I could sell for a lot of in-game money. To make a huge profit, I intended to raise a few on my ranch in captivity, and then collect their precious poop to sell in the market.

To maximize your slime poop plort yields, you're supposed to feed your slimes as often as possible. Every slime has a certain diet (vegetables, fruits, or meat) and a specific favorite item. Quantum slimes eat only fruit, but prefer a special fruit called a "phase lemon". To get phase lemons, you have to bring back a phase lemon from the wild, plant a phase lemon tree, wait for the fruit to mature, and then shoot a different fruit at it (like a cuberry, or a mint mango) to pop the phase lemon into existence. Compared to other crops, it's unusually labor intensive to cultivate and harvest phase lemons.

This is where Slime Rancher's other big system comes in, a cross-breeding mechanic that allows you to merge two slime types together. If you feed a slime with the poop from another slime, it will become a hybrid "largo" slime that inherits both types' diets and other properties, and it will poop out both types of plorts at once when it eats something. Two poops for the price of one! When you do this on purpose in Slime Rancher, you feel like a genius.

Recent developments in queer game studies, Summer 2017

Here's a few recent updates in the """discourse""" within the exciting world of QUEER GAME STUDIES!!!

First, there's a new call for papers in the long-running Game Studies journal -- this time the focus is on "queerness and video games."  The full CFP is here. If you're a student or academic (or anyone with a perverse tolerance for academic citation styles) then you should consider sending-in some original scholarship and/or maybe trim your thesis into a submission; full articles of 6500-8000 words are due by December 31st, 2017. Good luck!

Next, Miguel Sicart wrote a piece about "Queering the [Game] Controller." Sicart, as far as I know, doesn't identify as queer, so some may argue he thus cannot really "queer" anything -- so please allow me, a certified gay person, to try to unpack some of his ideas here:

Cleaning out some old Black Mesa archives for PC Gamer

Here are two old level design illustrations I did for a PC Gamer feature on level design in Half-Life 1, quite a few years ago. In the overview map, I focused on the construction of the Black Mesa Inbound chapter as a whole; and in the more focused cross-section, I concentrated my analysis on a single setpiece, the "shark cage" sequence in the Apprehension chapter.

(In the PC Gamer print version, the diagrams are annotated and labelled, but the image files I submitted were blank like these. I forget which issue it appears in. If you're interested in this topic, you can watch my Practice 2013 talk on this stuff to get roughly the same material.)

Anyway, here's a bit about my process and intent with these illustrations:

new tool: Yarn Weaver

I'm working on a game that uses the excellent Yarn and YarnSpinner narrative toolkit for Unity. For this project, I'm also collaborating with a narrative designer -- unfortunately, the Yarn editor doesn't actually have a play mode or a testing mode built into it -- which makes it difficult to collaborate, because the designer can't even run through the Yarn scripts without downloading the entire Unity editor and project source! What if she just wants to test a short conversation script or two?

So, I basically duct-taped the YarnSpinner example setup to this excellent UnityStandaloneFileBrowser (for native file open dialogs at runtime) to make a very small simple tool to open and run through Yarn scripts. It can display your text, parse all your variables, and render up to 4 choices.

I call this tool "Yarn Weaver". The project source files are on GitHub under MIT License, or you can download Windows and Mac OSX release builds here. I hope it's useful for people!

Toward an honesty of pixels: on Final Fantasy 12 HD and Quake 3 Arena

combined screenshots from Final Fantasy 12 (PS2, 2006) and Final Fantasy 12 HD (PS4 Pro, 2017)

You either love or you hate Final Fantasy 12, and you either love or you hate the somewhat recent trend of remastering old games to squeeze a few more drops of profit out of them.

I'm currently playing the remastered PS4 version of Final Fantasy 12 ("The Zodiac Age") and it's still the same old nonsense story about fantasy imperialists and magic crystal macguffins. One thing that surprises me, though, is how this remastered version actually looks worse -- it went from the apex of PS2-era 3D art to looking like a mediocre PS3 game running on a PS4.

When it first came out 17 years ago (!), the Playstation 2 famously had very little texture memory (4 MB!) and no texture compression (!) which meant developers had to get creative. Loyal readers of this blog know of my love of lightmap atlases and UV layouts, and so I'd like to talk about how the textures for the original Final Fantasy 12 on PS2 were utter masterpieces produced under severe constraints -- cramming so much detail into these small texture sheets, down to the pixels...

announcing: No Quarter 2017 on November 3rd in Brooklyn

poster by Sophia Foster-Dimino

A short while ago we announced the date and lineup for No Quarter 2017: it's on November 3rd at the Starr Space Gallery in Bushwick, Brooklyn, featuring new commissioned work by Auriea Harvey (of Tale of Tales), Droqen, Pietro Righi Riva (of Santa Ragione), and Kitty Horrorshow. We'll be flying out all four artists for the show, so if you attend, you'll be able to meet them and talk with them at the event.

For more info, check out this NYU Game Center page for the event. I'd like to copy and paste my short curator's statement here though --

For 8 years now, the No Quarter Exhibition has been paying game designers to make the games they want to make, and then throwing them a big fun party to celebrate and amplify their unique voices. We claim no ownership over the resulting work — we just want these artists to speak their mind, and so we give them space and support to do that. We think it’s a pretty great deal for them, but we also get a lot out of it: their act of creation, and our shared acts of play, help strengthen our communities.

Now, we do all this at a time when many people think we should isolate ourselves from the rest of the world — but we know that’s a very destructive attitude. It’s so destructive that, for the first time in the history of No Quarter, we are temporarily suppressing our vocal and insufferable belief in our city’s exceptionalism: this year, we are commissioning only artists based outside of New York City. We believe a wider diversity of backgrounds and identities can only enrich our understanding of art and community… oh, and it helps us make better games too.

Also happening right after No Quarter -- game convention GaymerX East in NYC runs Saturday / Sunday. Sounds like a cool fun weekend to me! Not to mention that flights and hotels are cheaper in November too, it's off-peak... just sayin'...
