Hi guys & gals.

I’m giving a talk about the inner workings of immediate-mode GUIs at GDC Europe tomorrow (in Cologne). Looking forward to doing it – it’s been my main Unity development area for the past 2 years, so I guess I somehow ended up being an expert on that subject It’s Monday at 2:10 – 3:00 PM

If any of you are there, I hope you come – and if you want to meet up in Cologne, drop me a mail or a PM on our forum, and I’ll try to squeeze you in.

I interact with the WordPress blog engine both here at work as well as at home for my personal blog. Given that WordPress experience, and the fact that I work at Unity Technologies, makers of the Unity Web Player, I guess it’s only fitting that I created a WordPress plugin to allow blog authors to easily include Unity Web Player content in their posts. My point of shame in this is the fact that I created the plugin last Fall and haven’t really done much with it since, my bad!

Example: The Island
Here is an example file that you developers should recognize, it’s a published version of the Island demo we include when you install Unity:

Description
The plugin is simple to use and requires some straightforward mark-up tags within your blog post. Those tags are read by WordPress when showing the post and the needed page edits will be made to show your Unity Web Player content. The plugin includes support for both Unity Web Player 1.x and 2.x content. The plugin allows you all the same options as the native object/embed tags so you can enable/disable the context menu or the ability to go fullscreen, to use custom loading screen graphics or to specify your own install prompt image and more.

Download
Please feel free to download my WordPress plugin and put it to use right away:

WP_UnityObject

The download contains a readme file with instructions, have fun!

Edit Note (May 20, 2009): the download link has now been changed as the plugin is available from the Resources area on our website.

I always thought that the license comparison page on the Unity website was – well, not confusing, but at least not quite as clear as it could be. That’s why I have spent the last few days creating a new Unity License Comparison table with the help of my colleagues, where the differences can be seen absolutely clearly between Unity Pro, Unity Indie, Unity iPhone Advanced, Unity iPhone Basic, and even Unity Wii.

So if you’re in doubt about which features come with which licenses, head straight to:

Assuring quality is a tricky task, and involves a lot of people — testers, developers, and even you the users! There are thousands of you and only a few of us, so today I want to talk to you about this:

If you see this Bug Reporter appear, odds are that you’ve just experienced a problem in Unity. I can honestly say that whatever it is, we want to fix it. As part of our QA processes, the test team (currently: me, Jens, Caitlyn, Rasmus, and Oleg) constantly review “the queue” of publicly submitted bugs in our QA/support database. We can do more with some bugs and less with others, and I want to help everyone understand how to tell us about their problem so we can actually fix it.  When we review bugs, here’s what we think about:

What happened to this user and how did it happen?

Can I force Unity to do it again for me?

If we can answer both of these questions then we have enough information to investigate the issue and communicate our findings to you the user, or to a developer when discussing a fix for the issue. For this reason, the information you write in details 1) and 2) in the bug report is critical in helping us squash the bug forever.

Now, if we can’t understand what happened in the first place then there isn’t much we can do about the problem. So under detail 1) we ask that you thoroughly and completely describe the problem, using as much detail as you possibly can. The worst thing you can do here is write nothing. Writing anything you think is relevant to the problem is always better than writing nothing.

Once we understand the issue, we want to reproduce it. When we try to reproduce it, we perform a series of actions or “repro steps” to make the bug occur again. The first place we look for help determining the right set of repro steps is under detail 2). If the bug you’re reporting is frequently or consistently occurring, the best thing you can do is describe a discreet series of steps that we can take in order to reproduce the bug.

Sometimes a bug is specific to the scripts or assets in your project folder.  In case it is, we ask that you always attach your project folder so we can make our test environment match your development environment as closely as possible. The bug reporter will automatically zip your folder and upload it, even if it’s as large as 500MB. And don’t worry, your project will only be used for testing purposes and it will never be shared outside of the Unity Tech office. If you can isolate the problem down to an extremely simple project folder that contains only the assets and objects relevant to the bug, even better!  Either way, providing a project folder will greatly increase the likelihood that we can successfully reproduce the bug and fix it. But I’ll reiterate: if we cannot reproduce the bug, we cannot fix the bug.  So pretty please with sugar on top, attach your project folder because we hate not fixing bugs.

I hope this has been an insightful look into our QA processes and you understand a bit more about the purpose of the bug reporter. To learn even more about bug reporting and the Unity QA processes, please watch the “How to Get Your Bugs Fixed” presentation video from Unite ‘08.

I think there are a lot of resources that are important but people might not have seen or skipped over it. So I am putting up a list of the most overlooked but important resources.

Getting started
The best way to get started if you know nothing about Unity is to go through the 3D Platform Tutorial. With this in-depth tutorial you can learn how to make a 3rd person platform game in Unity, but at the same time you will learn all the basics of Unity that will give you a head start when creating your own game.

Unity Locomotion system
If you are doing a lot of character animation in your game, you must check this out. Rune’s Locomotion system was presented at GDC 2009 in a fully packed session. The great thing about it is that it does stylized IK, meaning that it uses the existing animations to do good looking motions and only minimally adjusts them to place feet on the ground etc. It also scales really well, you can start out with a simple walk cycle and it will automatically synthesize sidestep / run / backwards animations for you. If you provide more animations the animations will simply look better.

Watch the Unite 2008 talk here.

Visual Studio Integration
In our roadmap we announced Visual Studio integration for Unity 2.6. However you can already use Unity with Visual Studio very well. Lucas Meijer has a blog post on how to create Visual Studio projects from a Unity Project folder automatically here.

Shaders
Amir’s Unite 2008 Shader talk is the defacto best tutorial on building shaders. He reshot the session into a 2 hour talk so he could go through all the details.

Customizing the asset pipeline
Lucas is really into tightly controlling the asset pipeline and automating every single bit. Fortunately Unity is very extendable, so he has a lot of places where he can plug in. Watch the talk here.

Matthew’s Physics Talk at Unite 2008
I generally love hearing Matthew’s talks. Got to love the pictures. This year on car physics was very useful.

Unity GUI
Nich’s Unite 2007 talk on how to create your own GUI controls is still very relevant.

The wizkid Forest talks about particles
Forest Johnson, a (then) 15 year old kid single handedly programmed the Avert Fate demo, he did some awesome particle effects too and then gave a kickass impromptu particle talk at Unite 2007.

Blogs about Unity:
The Flashbang guys have an awesome blog about Unity, that contains deep technical information that sometimes even I didn’t know about.

Lucas has a great blog about Unity with a lot of very useful information.

Somebody made  a site collecting video tutorials about Unity.

Woah my first blog post! And I am going to dive right into the roadmap. This time we are taking a look at what is coming up in the near future.

Unity 2.6

Unity 2.6 is our next big release in the Unity 2.x series (And will be available as a free upgrade). We are planning to release Unity 2.6 sometime later this summer. Here’s some of the things to come:

It’s been a busy year already for everyone in the Unity community and the year is still just getting started! Unity 2.5 is around the corner, GDC looms close and as of late there have been a few pieces of Unity content making waves that are well worth your time and attention. Specifically I’m referring to Zombieville USA (Mika Mobile) and Blush (Flashbang Studios).

I remember a long time ago when I first heard of this odd new (at that time) site called Orkut, I readily signed up and started my own person social networking experience. Before long it seemed that Orkut was passe and it was replaced with Friendster. Again I signed up and joined the fray, but I soon grew weary of the experience and dropped off the radar for a bit. Instead of using social networking sites I focused on my own personal website and interest-specific forums for meeting up and interacting with others online. Due to not fully enjoying those early experiences I was slow to get back into things with the advent of LinkedIn, MySpace, Facebook and of course one of the newest entrants into the fray, Twitter.

Slowly but surely I succumbed, ultimately signing up for both LinkedIn (here) and Facebook (here) skipping over and avoiding the whole MySpace experience. As of late I’ve come across lots of folks jumping on the Twitter bandwagon and so I figured that it was finally time to give it a go. So today I finally signed up for a Twitter account, feel free to stalk me… err, “follow” me, if you’d like:

I’m now following a number of folks, many of whome are coworkers at Unity Technologies or members of the Unity Community. Are you on Twitter? Will I follow you next? <insert evil music here>

As most of the Unity universe already knows, we recently announced that Unity 2.5 is coming soon, and that among other new features it will most prominently include Unity editor support on Windows. In case you live in a cave or are otherwise out of the loop with respect to Unity news:

Unity: Coming Soon in Unity 2.5

I think it goes without saying that this has caused an incredible stir amongst the game developer community and it’s caused a lot of new eyeballs to look our way. For those of us working on Unity it’s an incredible time to say the least and all signs seem to indicate that this year’s roller coaster ride is just getting started…

The new year has hardly begun and it’s already been incredible, I say that as it feels to me like Unity and Unity content are in the news a lot as of late. While I know that those of us at Unity Technologies have been firm in our belief that Unity is the best thing going in game development, I think a lot of the recent media coverage and content launches are helping to show that’s really the case. Given that, I thought I’d take a minute and point out some of the recent media mentions for others to check out and perhaps share some of your own. Enjoy.
