A tweet by Michael Hutchinson on C#/Mono usage in games caused me to do a couple of short replies (one, two). But then I started thinking a bit more, and here’s a longer post on what is needed for C# (and more specifically Mono) to be used in games more.

In Unity we use Mono to do game code (well, Unity users are doing that, not us). Overall it’s great; it has tons of advantages, loads of awesome and a flying ninja here and there. But no technology is perfect, right?

Edit: Miguel rightly points out in the comments that Mono team is solving or has already solved some of these issues already. In some areas they are moving so fast that we at Unity can’t keep up!

Here, ryg nails it:

why would you want sound and physics when you can have sparsely clothed ninja space marine amazon secret agents riding on chainsaw-hoofed flying pink stealth space unicorns through a brightly colored dystopian african urban jungle fantasy wasteland island state populated with mutated propaganda-spewing gas mask-wearing alien nazi zombie demons that entered this island planet dimension through a hellgate portal invasion triggered by a black magic freak teleportation experiment resonance cascade accident caused by a power-hungry mad scientist wizard evil genius working for a multinational corporation conspiracy of lawyers and weapons manufacturers without morals, and all that in its proper realtime dynamically lit globally illuminated deferred-shaded parallax-occlusion-mapped ambient-occluded shadow-buffered high dynamic range silky smooth glory?

Pretty much sums up the mainstream game industry!

So LTGameJam 2009 is over. I’ve been there as part organizer, part participant, so my views are both biased and incomplete (being an organizer means you have to run around a bit, instead of just focusing on making the game).

The theme for the games was “as long as we have each other, we will never run out of problems”. Additionally, games had to be short (5 minutes of play or less), and somehow incorporate one of “affectionate”, “patriotic” or “missing” words.

I worked on a Missing Peace game. It’s nothing really fancy, does not quite follow the idea and incorporates the above mentioned words in a cheap way (“just stick it into a title! haha!”). It was probably the most polished game from all games made there though (for some definition of polish)… too bad it’s not actually fun to play :)

Oh well. I just did not have any interesting ideas, and wasn’t particularly inspired, so there is the result. Probably burnout of trying to finish Unity 2.5 at work had it’s toll as well.

Overall, the good parts about this game jam:

• It was fun (hey, that’s the whole idea)
• Some very positive progress, compared to LTGameJams 2002/2003: more people (20-25, up from 10-15), much better proportion of artists (about 30%, up from almost zero), more people who don’t know each other, more games made by folks outside of nesnausk! group :)
• Some of the ideas that were brainstormed have interesting bits.
• Did I mention it was fun?

On the downside, I get the feeling that the games made this time were not crazy enough. GameJams are meant to generate totally whacky, crazy and amazing ideas; however this time most of the games were known game mechanics, pretty safe idea and so on. Have to improve on that the next time.

So that’s about it!

Off to local Global Game Jam!

(if this sounds like a rehash of a blog post on blogs.unity3d.com, well, it is…)

Everyone knows the Valve’s hardware survey. But what if your target game players are not the traditional “big budget AAA game” type? For example, at the moment most Unity Web Player games are oriented to much more casual market, so hardware there might be very different. And indeed, turns out it is quite different.

Without further ado, here’s the data we have: Unity Web Player hardware statistics.

It’s about two million data points since we started gathering it earlier this year.

Some subjective points of interest (I’ll be using current data for 2008 Q3 here):

• Operating systems: Mac OS X is 2.5%, the rest is Windows. 64 bit Windows haven’t really picked up yet (0.7%). Windows 2000 is dying fast (0.7%). OS X Leopard already took over OS X Tiger.
• CPUs: poor Transmeta :) Dual core CPUs are becoming the norm (46%).
• Graphics cards: quite sad, in fact… top 15 cards are slow or horribly slow. Capability wise, they are quite good, with about 70% having shader model 2.0 or higher. Shader model 1.x cards are dead. “Can has DX10” is 2.7%.
• Casual machines don’t have lots of RAM. Nor lots of VRAM.
• Most popular nvidia driver? 56.73. Looks like this is the driver that comes integrated in XP SP2… Now, who says regular people ever update their drivers? Likewise, vga.dll (i.e. standard VGA) is 1.6% of machines; additional 1.5% don’t report any driver (not sure how that happens…).

So yeah. Casual machines: capabilities quite okay, performance low, low, low. That’s life.

I decided to make a very small game with Unity. Coincidentally, Danc of Lost Garden fame just announced a small game design challenge called “Play With Your Peas“. It comes with a set of cute graphics and a ready-to-be-implemented game design. What more could I want?

So it’s a small very small 2D game without any next-gen bells and whistles. It can probably be done casually on the side, by allocating an hour here and there. We’ll see how it goes. Hey, I never actually done any game in Unity, I only make or break some underlying parts…

Of course, first I start with no game, just imported graphics. Hey look, I can do sprites!

Then cook up some base things: define the game grid, throw in some basic user interface on the right hand side, and make it actually do something. This wasn’t so hard; that already gets me an almost working level building functionality. It does not have fancy block building delay or block deletion yet; that will come later.

Next come basic physics. Danc’s design calls for simple arcade-like physics (things moving at constant speeds, bouncing off at equal angles, and so on), but in Unity I have a fully fledged physics engine just waiting to be used. Let’s use that.

The design has sloped ramp pieces, which are hard to approximate using any primitive colliders, so instead I’ll use convex mesh colliders for them. Now, on this machine I only have Blender, which I totally don’t know how to use; and I was too lazy to go to PC and use 3ds Max there. What a coder does? Of course, just type in the mesh file in ASCII FBX format. Excerpt:

; scaled 2x in Z, by 0.85 in Y
Vertices: -0.5,-0.425,-1.0, 0.5,-0.425,-1.0, -0.5,-0.425,1.0, 0.5,-0.425,1.0, -0.5,0.425,-1.0, -0.5,0.425,1.0
PolygonVertexIndex: 0,1,-3,2,1,-4,1,0,-5,2,3,-6,0,2,-5,2,5,-5,3,1,-5,5,3,-5

It’s a left ramp mesh! So much for fancy asset auto-importing functionality, when you don’t know how to use those 3D apps :)

After a while I’ve got peas being controlled by physics, colliding with level and so on. Physics is very bad for productivity, as I ended up just playing around with pea-stacks!

So far there’s no game yet… Next up: implement some AI for the peas, so they can wander around, climb the walls, fall down and bounce around. I guess that will be more work and less playing around… We’ll see.

So I decided to check out Crysis myself. A demo for a non-gamer like me would be perfect, I thought.

It’s probably three frames per second. In the menu!

I did not see the game itself yet, got bored while waiting for the after-menu-but-before-game intro movie to end (it’s not skippable, and it also ran at about three FPS). This is after watching half a dozen obligatory before-menu intro movies at 3 FPS with stuttering sound (“nvidia,vidia,vidia,vidia… the way it’s meant,meant,meant,meant…” – TWIMTBP).

All of this on a half-decent PC, I think – Intel Core 2 Quad, 4GB RAM, Radeon 3850, Windows XP, latest drivers, none of extra stuff running; the PC is able to run other 3D stuff just fine. I’m sure the developers and EA’s testing labs have tested everything extensively, but sometimes something completely random apparently can make things be oh so slow. Oh well. Get back to work.

This is just too cool: Off-Road Velociraptor Safari game. Read that again. Who says game industry is all about sequels and safe licenses?

You drive a jeep with a spiky ball, and your goal is to chase down raptors and send them to the future, presumably to end world hunger. Or you can do stunts. And you the driver are a raptor, only you wear a hat and a monocle.

Just go and play it already: raptorsafari.com. It’s free.

Or watch a trailer if you want to miss all the real fun, or read a press release. Of course it’s made in Unity, in two months from start to finish.

To me, this is a perfect example of focus. Basically there are three things – 1) vehicle, 2) raptors, 3) physics mayhem – and that almost describes a game. Yes, there are crates and stunts and achievements and online leaderboards, but that’s just additional stuff on top of the core game.

Sounds like a good plan for making game prototypes:

1. Think up a game idea and describe it in one concise sentence. The idea may be totally crazy, like in this case. I guess an idea like Velociraptor Safari would not fly in a pitch at any publisher, but that does not matter at this point.
2. Get a small team of smart people. In Flashbang’s case, it seems they were 4 to 7 person team.
3. Choose a game engine/toolset that will allow you to make your game fast. *cough cough*
4. Do it!

All the above requires is a small smart team and groceries/rent for a couple of months.

Your original idea may be totally crazy, but with the actual working prototype at hand it might just work. Looks like Velociraptor Safari really clicked something on the internets (see Kotaku, JayIsGames, Destructoid, TIGSource, AtomicGamer, …).

Flashbang Studios just launched Splume, probably the first game out there* made with Unity 2.0. It just won our “Top DOG” competition by the way.

It’s a cute little gem, or alternatively, “Puzzle Bobble meets Ageia’s PhysX engine”. Lots of levels, user level editor, some AJAX magic and so on, and everything made in about four weeks. Matthew has some technical details for the curious.

Here are some shots and a youtube trailer for the lazy ones. The youtube trailer uses music from 8bitpeoples which can’t be bad :)

But really, you should just go and play it: splume.flashbangstudios.com

* I stand corrected: When Orcs Attack also was made with Unity 2.0, and it was released earlier!

I just have to blog this: shockwave.com just launched a Unity web game – MegaPixel. It’s a pure, abstract, and mega-fun FPS. It’s set up in a very small space (the levels are basically boxes with several smaller boxes inside), and it pretty much uses a single texture for the whole game, and it does not use much more than particle effects for everything (the levels, enemies, weapons and everything else is just particles). Pure genius.

I like it! That says a lot, because last time I played FPS was ages ago. Finally, someone made a game that I can like again. How much I’m biased because it’s made with Unity… decide for yourselves :)

Now the killer part: the game is designed and developed solely by a 15 year old – Forest “Yoggy” Johnson. How cool is that?

Enough talking, just go and play it. And remember that you didn’t see cool until you get to the robot level!
