The trouble with Linux Games

Blender, Ubuntu, games, gimp, inkscape, linux, programming 0 Comment »

mario_icon_applescripts_4527_thumbIn my web wandering I recently came across the Ubuntu Gaming team which is a marketing effort which was started from a post over on pinstack.

Here is the problem: the Linux gaming landscape is a wasteland, and more marketing couldn’t hurt but it sure wont fix the problem.

So what does Linux Gaming really need? Well I thought about it, and here is what I came up with.

A Lack of High Quality Game Engines

When you look at the titles of the really successful game company’s such as Ubisoft, Epic, and others they all run on these amazingly powerful proprietary game engines. The game engine itself is a huge piece of the puzzle when it comes to any half-way decent game and unfortunately this is an area where Linux is lagging behind other platforms. One could say that the reason for this is because there are simply not enough open-source developers dedicated to the cause of creating high quality open-source game engines (quite a mouthful), and while that may be partly the reason I suspect that organizing those developers is also to blame.

Open source works differently than regular development, in an open source project you’re aren’t assigned to a team and given a to-do list and a manager to check your list and while you may be thinking “Hey that sounds good!” The downside is you aren’t given a paycheck either. You are simply a volunteer who does what she wants when she wants on what she wants, and in that kind of situation it is very hard to accomplish everything that needs to be done.

Despite the inherent problems of lack of developers and lack of organization there are some open-source game engines out there who have figured out how to get things done and are actually quite good! Take two open-source game engines for example: Panda3d: an interesting combination of C++/Python, and jMonkeyengine: written in Java. Both of these engines have been used to make commercially successful games so they are certainly respectable projects, but realistically they are years behind even moderately successful proprietary engines despite being two of the best  engines that the Open Source world has to offer.

A Lack of Game Artists

You could have the best game concept in the world but without professional artwork your game is going to look end up looking like a pile of molten slag and unless your game is about the zany adventures of a boy and his pile of molten slag then you have a serious problem.

I wont go into just how eye-popping even the moderately successful proprietary games look these day because I’m sure we know already, the real question is how did those games get to look so good and how can we bring that over to the Linux system.

The first thing to understand: Game artists can’t work without tools. As an artist my tools are just as important to me when I’m creating art as when I am creating code, and many of the artists that I know also feel the same way. Non-artists may find it surprising that artists care deeply about their software, perhaps you thought that Emacs vs Vim type wars only happened in geeky programming mailing lists but let me tell you that artists can feel just as strongly about their favorite weapons of choice.

So what is the quality like of the artist tools available for Linux. The best three available are Blender, Gimp, and Inkscape and I can say in all good faith that they are simply amazing. I’d really like to emphasise this point. Just 2 or 3 years ago I would not and could not have said this with such confidence, but the beauty of open source is that it just continues to get better and better. I have total confidence that for anything I need to do open source tools meet the challenge.

However tools are only one piece of the puzzle, another important factor is money and recognition. Money is important to every professional but it is particularly important for artists because art is one of the more difficult industries to make a successful living. Your average programmer doesn’t have that much difficulty finding a job after college but that is not the case with the average artist despite being no less talented.

If I were to ever setup an open source game I would ensure that any serious artists linked to the project received a percentage cut of the donations or in some other way be compensated. I would also make sure that the artists got in-game and on-site named credit for their work and contributions.

A lack of Games Itself

By “Game” I mean the concept and code which connects the players to the game-engine. Despite the two previous problems of a lack of high quality game engines and a lack of game artists this problem is in my view the most difficult to overcome. People need to write more games for Linux, there is no way around this.

You may have a good idea, but I’ll tell you what Guy Kawasaki told me once and that is that good ideas are not hard to find, it is making them happen which is the trouble.

How do we get around this? Tie a bunch of artists and programmers together and don’t let them go until they start making some awesome games? That seems like a good idea but in actuality it is a really hard thing to do.

My Open-Source Indie Game Developer Formula

I think a lot of people would like to head down the road (myself included) of independent open-source game developer, but how exactly to do so is a bit of a mystery.

After some thought I’ve come up with the following suggestions on how it could be done:

1) Write out a rough draft of your concept: It doesn’t have to be perfect but you need to set some simple goals about what you are actually trying to accomplish with this project.

2) Figure out your business plan, how will you make money from this game (AdSense? donations? whatever). Having a business plan is important, if you do not plan for this game to make any money whatsoever then chances are the development will be slow going and you will have trouble finding support or getting recognition for your work. Do not waste time planning to get rich, but do figure out some way to turn your efforts into some cash. This will help you to stay motivated.

3) Write and release an open-source proof of concept that runs, it doesn’t have to be pretty it doesn’t have to be fun it doesn’t even need to work, it just needs to run.

4) Turn to the Open Source community and to your friends for support, ask bloggers that you know to write an article or to mention your project on their site. Start to offer incentives to artists who would be willing to help your project. Here is where the offering to give name credits on the work as well as a slice of the pie (i.e. money) which I mentioned earlier would help a lot I think.

5) After you’re done schmoozing for help, you need to return to your project and continue to work. Push out another release even if you’re still all alone and even if the game is still as ugly as hell. Once your next release is out then head back to the blog sphere again and try to drum up more interest and help for your project, then once again return to your project and continue to work.

6) Repeat step 4 and 5 until you reach the goals set out in step 1

I hope this article will interest and motivate some of you out there to give open source game development a chance. Linux is a great platform with great tools and some pretty good open-source game-engines just begging to be abused.  All it needs is more people with killer game concepts and enough willpower to get a basic game project up and running.

Setup Guide: Maya 2009 Sp1 Linux x64

Maya, Ubuntu, linux, x64 0 Comment »

Since writing the lamentation about my absence from the Linux scene I discovered that I had actually installed an older version of Mays since SP1 is now out for 2009

So this seemed like a good time to hammer out  a more in depth guide to setting up Maya 2009 x64 on Ubuntu Jaunty.

Pre-install setup:

First you will need to make sure that CSH is installed for the Maya setup scripts:

sudo apt-get install csh

Next some directory house-keeping for Maya :

sudo mkdir /var/flexlm

sudo cp <your Windows Maya 2009 license file “aw.dat”> /var/flexlm/

sudo chown 444 /var/flexlm/aw.dat

if [ ! -f  /usr/tmp ]; then sudo mkdir /usr/tmp; fi

sudo chown 777 /usr/tmp

Installing Maya:

Now we are ready to start installing Maya.

Although Maya comes packages natively from Autodesk in rpm format that is not a problem, just install the rpm tool for Ubuntu

sudo apt-get install rpm

Now download the Linux version of Maya 2009 from Autodesk, it only comes in one flavor x86_64 (Also known as AMD64) which can only be installed on a 64bit version of Linux.

wget http://images.autodesk.com/adsk/files/autodesk_maya_2009sp1a_linux64.tgz

It takes around five minutes to download, after you download right-click and choose “extract here” and then navigate into that folder using the terminal and install the rpm’s

sudo rpm -ivh –nodeps AWCommon-11.5-19.i686.rpm AWCommon-server-11.5-19.i686.rpm Maya2009_0_64-2009.0-452.x86_64.rpm

Post-install clean up:

Once that is finished click the “System” menu at the top of the screen and go to “System -> Preferences -> Windows” and change it so “Movement Key” = “Super”

Then add this line “MAYA_MMSET_DEFAULT_XCURSOR=1″ to the file located at /home/<your user name>/maya/2009-x64/maya.env

Adding that line will tell maya to always use the default cursor if you dont set this maya will change the cursor when you use it.

The final thing we must do before launching Maya is to change the xorg.conf file to disable the Composite feature.

Edit the file /etc/X11/xorg.conf  add these lines to the bottom

Section “Extensions”
Option        “Composite”    “Disable”
EndSection

Now, restart your desktop to make sure you edited the file properly.

If the desktop does not restart press CTRL+ALT+F1 and log into a terminal and check the file for spelling mistakes then restart your computer.

Once that is all finished, just launch Maya by pressing ALT+F2, and typing in “maya” and pressing enter.

If everything went properly Maya should pop up on your screen in just a few seconds. You should not see the Licensing window.

Now feel free to add a short cut to your hot-bar or menu, I will leave that up to you.

Trouble Shooting:

If you get errors when you try to launch Maya saying that it is missing necessary libraries then I suggest installing and running a packaged named “getlibs”

wget http://frozenfox.freehostia.com/cappy/getlibs-all.deb

sudo dpkg -i getlibs-all.deb

sudo getlibs /usr/autodesk/maya/bin/maya.bin

If you have any licensing problems please contact Autodesk for further support.

Hope this guide is useful to some out there.

Maya is an amazing package I just wish it was open source, but I’ve got my eye on Blender maybe someday I’ll make the switch.

I really regret moving away from Linux a year ago.

Autodesk, Maya, Ubuntu, linux 2 Comments »

As you may know I’m just finishing up a 1 year course of Computer Animation/Modeling at college and I’m currently working on my year end demo reel.

Before I started school I decided that I would un-install Linux and work primarily using MS-Windows because that’s what the school would be using and I wanted my system to “just work” as they say.

Well now that the year is over let me tell you that I made a huge mistake.

Here is the list of problems that I’ve had with my computer this year:

First I had WinXP crash into an un-bootable state just a few months after the original install which required a reformat and reinstall, so i decided I’d upgrade to Vista x64 which I had hoped would be more stable.

After installing Vista x64 I had driver issues for several weeks, and then my video card died, and then one of the two internal hard-drive in my computer died (not the OS drive thankfully) and then finally Vista crashed into an un-bootable state just like WinXP, requiring a reformat and reinstall, so I decided to switch back to WinXP which at least has less driver issues.

Finally, to top it all off after reinstalling WinXP and getting my system back up to good working order I was unlucky enough to pick up a Windows Virus which set me back to square one.

So enough is enough I am tired of playing the Windows Game, it is time to reinstall Ubuntu Linux.

The first thing I installed after getting the system setup was of course Maya 2009 x64 and I can tell you it was incredibly fast and easy:

#rpm -ivh –nodeps

That’s all it took, and then I inserted my old windows License file and Maya was good to go.

I did have to change 2 things: the desktop uses the ALT key for some of its hot-keys and so I had to switch this over to the Windows-Logo key so that Maya could use ALT (pan, rotate, etc, etc).

Next I had to edit the xorg.conf file which manages the desktop display and add these lines:

Section “Extension”

Option “Composite” “Disable”

EndSection

Because Xorg tries to do some fancy screen display stuff which Maya doesn’t like so these lines just turn off the Compositing feature of the desktop.

Now I’m using Maya 2009 x64 in Ubuntu Linux, the program loads in under 5 seconds (compared to between 30 to 45 seconds in WinXP) and everything simply works the way it should Ubuntu took care of all my drivers and setup everything else so that it all really does “just work”.

Now, I can finally get back to work and finish my demo reel!
