XNA Game Studio is a finicky bugger, and it’s even more finicky now that it is no longer being maintained. One of the biggest issues is that it doesn’t work properly with the latest version of Visual Studio, 2012. However, you can cajole it and reassure it that things will be OK.
One way to do so is to essentially “translate” an existing, working install, and “hack” it’s configuration so that it works in Visual Studio 2012. In order to get the appropriate file setup, you will have to install XNA Game Studio 4 into Visual Studio 2010.
With Visual Studio 2010 Installed and XNA Game Studio happily installed, you can force the XNA 4 installation to get along with Visual Studio 2012. XNA Game Studio installs by default in
%ProgramFiles(x86)%\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft\XNA Game Studio 4.0
the first step in whipping it into shape is to simply copy that folder to the appropriate target location in the Visual Studio 2012 installation. This is located, by default:
%ProgramFiles(x86)%\Microsoft Visual Studio 11.0\Common7\IDE\Extensions\Microsoft\XNA Game Studio 4.0
Not done yet, though- it’s copied over, and VS2012 will try to run it, but it will look inside the plugin manifest, see that it doesn’t say it works with VS2012, and then explode (well, it doesn’t explode, it just doesn’t load the extension, but that’s hardly very exciting.) In order to do so, you will need to open and edit the extension.vsixmanifest file within the XNA Game Studio folder you copied (the new one, that is). You’ll notice this:
What you can do should be pretty clear now; just flooble1 the “Version=”10.0” entry to point to version 11. Save the file, Open Visual Studio 2012, and BAM! Game Studio projects should now be available via the New Project Dialog Templates.
Sometimes- perhaps You’ve been badmouthing Visual Studio behind it’s back; Maybe you complained under your breath about how slow Visual Studio 2012 is when you went to deal with Intellisense. Maybe you told Visual Studio 2012 where it can shove it when it provided you with a helpful popup tip. Visual Studio 2012 has feelings and, like a Cat, never forgets it’s enemies.
On the other hand, you might just need to delete the extensions cache file. The extensions cache file can be found at “%LocalAppData%\Microsoft\VisualStudio\11.0\Extensions”; specifically, the “extensionSdks.en-US.cache” and “extensions.en-US.cache” files in that folder. Delete them with impunity and regret nothing. Visual Studio 2012 has forced your hand. Innocent Files must die so that Game Studio 4.0 may live.
1flooble is a word I just invented now. Patent Pending!
The following consists of my opinion and does not constitute the passing on of an official statement from Microsoft. All thoughts and logic is purely my own and I do not have any more ‘insider’ information in this particular topic than anybody else
I’ve been hearing from the community a bit of noise about Microsoft’s XNA Framework- a Programming library and suite of applications designed to ease the creation of Games- being cut. A google reveals a lot of information, but a lot of it is just plain old rumours. The only one I could find that was based on actual information still makes a lot of assumptions. It is based on this E-mail:
Our goal is to provide you the best experience during your award year and when engaging with our product groups. The purpose of the communication is to share information regarding the retirement of XNA/DirectX as a Technical Expertise.
The XNA/DirectX expertise was created to recognize community leaders who focused on XNA Game Studio and/or DirectX development. Presently the XNA Game Studio is not in active development and DirectX is no longer evolving as a technology. Given the status within each technology, further value and engagement cannot be offered to the MVP community. As a result, effective April 1, 2014 XNA/DirectX will be fully retired from the MVP Award Program.
Because we continue to value the high level of technical contributions you continue to make to your technical community, we want to work with you to try to find a more alternate expertise area. You may remain in this award expertise until your award end date or request to change your expertise to the most appropriate alternative providing current contributions match to the desired expertise criteria. Please let me know what other products or technologies you feel your contributions align to and I will review those contributions for consideration in that new expertise area prior to the XNA/DirectX retirement date.
Please note: If an expertise change is made prior to your award end date, review for renewal of the MVP Award will be based on contributions in your new expertise.
Please contact me if you have any questions regarding this change.
This is an E-Mail that was sent out- presumably- to XNA/DirectX MVPs. I say presumably because for all we know it was made up to create a news story. If it was sent out, I never received it, so I assume it would have been sent to those that received an MVP Award with that expertise. It might have been posted to an XNA newsgroup as well. Anyway, the article that had this E-mail emblazoned as “proof” that MS was abandoning XNA seemed to miss the ever-important point that it actually says nothing about XNA itself, but actually refers to the dropping of XNA/DirectX as a technical Expertise. What this means is that there will no longer be Awards given for XNA/DirectX development. It says nothing beyond that. Now, it could mean they plan to phase it out entirely- but to come to that conclusion based on this is a bit premature, because most such expertise-drops actually involved a merge. For example, in many ways, an XNA/DirectX expertise is a bit redundant, since XNA/DirectX works using a .NET Language such as VB.NET and C# and very few XNA/DirectX MVPs truly can work with XNA in any language at all, it might make sense to just clump them with us lowly Visual C# and Visual Basic MVPs.
To make the assumption that XNA is being dropped based on this E-mail is a bit premature. In my opinion, I think the choice was made for several reasons. I guess some of the misconceptions might be the result of misconceptions about just what a Microsoft MVP is. First, as I mentioned before, a lot of the expertise of XNA/DirectX involves an understanding- and expertise- in some other area. Again, Visual C#, Visual Basic, Visual C++, etc. So in some ways they might have considered a separate XNA/DirectX expertise redundant. Another reason might have to do with the purpose of an MVP. MVP Awards are given to recognize those who make exceptional community contributions in the communities that form around their expertise. For example, my own blog typically centers around C#, solving problems with C# and Visual Studio, and presents those code solutions and analyses to the greater community by way of the internet, as well as sharing my knowledge of C# and .NET in those forums in which I participate. MVP awardees don’t generally receive much extra inside information- and that they do get is typically covered by a NDA agreement. The purpose of the award is to also establish good community members with which Microsoft can provide information to the community. MVPs are encouraged to attend numerous events where they can, quite literally, talk directly to the developers of the Products with which they acquainted. in some way you could consider MVPs “representatives” of the community, who are chosen because their contributions mean they likely have a good understanding of any prevalent problems with the technologies in question, and interacting with MVPs can give the product teams insight into the community for which their product is created. Back to the particulars here, however- as the E-mail states, XNA Game Studio is not under active development. Now, following that, it seems reasonable to work with the assumption that either that product has no Product Team, or those that are on that Product Team are currently occupied in other endeavours, or other products for which their specific talents are required.
It’s not so much that they are “pulling the plug in XNA”- the product is currently in stasis. As a direct result of this, it makes sense that without an active Product Team, having specific MVP Awardees for that expertise isn’t particularly useful for either side- MVPs gain from personal interactions with the appropriate Microsoft Product team as well as fellow MVPs, and Microsoft gains from the aggregate “pulse of the community” that those MVPs can provide. Without a Product Team for a expertise, that expertise is redundant, because there is nobody to get direct feedback. This doesn’t mean the XNA community is going away, just that, for the Moment, there is no reason for Microsoft to watch it’s pulse, because the product is “in stasis” as the OS and other concerns surrounding the technology metamorphize and stabilize (The Windows 8 UI style, Windows Store, and other concerns in particular). Once the details and current problems with those technologies are sussed out, I feel they will most certainly look back and see how they can bring the wealth of game software written in XNA to the new platform. Even if that doesn’t happen, XNA is still heavily used for XBox development- which is also it’s own expertise.
I hope this helps clear up some of the confusion that has been surrounding XNA. It doesn’t exactly eliminate uncertainty- this could, in fact, be a precursor to cutting the technology altogether. But there is nothing to point to that being the direction, either.
Call me old fashioned, or possibly slow, but for some reason I never seem to be using the latest version of a piece of software. Until recently I was doing all my .NET work with Visual Studio 2008; this was because VS2010, bless it’s heart, felt sluggish to me.
With the pending release of Visual Studio 2012, which as I write this is available for a free download as a Release Candidate, I decided I’d bite the bullet and start switching. This was also because I wanted to dip into XNA, and As near as I could tell the latest version only worked in conjunction with VS2010. I had to reinstall Resharper to get proper VS2010 support, since I had installed Resharper before I installed VS2010, and after applying my own preferences to both Visual Studio as well as Resharper, I was able to get back into coding. (Am I the only person who hates the preferences IDE’s have to automatically complete parentheses and braces and stuff? I always find myself typing the ending parenthesis, ending up with double, so I delete the extra ones, then I forget where I was in the nesting; and if you get used to that behaviour, suddenly you find yourself not typing ending parentheses in plain-text editors. You can’t win! I’m not a big fan of that sort of autocomplete; Actually, I don’t really like any form of autocomplete, but that’s sounds like material for another post altogether.
The End result is BCDodgerX, which is available on my main downloads page. It is essentially a rewrite of BCDodger, with an unimaginative X added onto the end that means pretty much nothing.
Overall, VS2010 is actually quite good. Call it a belated review; I almost purposely fall several versions behind for some reason. I cannot say I’m overly fond of the use of 3-D Acceleration within a desktop application, but at the same time all the Controls still have the Windows Look and Feel (which is my main beef with Java’s Swing libraries, which have a look and feel all their own), and the desktop itself is accelerated with Aero anyway so I suppose it’s only a natural progression. (Besides, I don’t play games very often and this 9800GT should get some use…).
The tricky question now is when I should start migrating my VS2008 projects to 2010, and whether I should switch to the latest framework. I can switch to VS2010 without using the latest framework, of course, but I wonder what benefits I will see? One day I’m sure I’ll just say “screw it” and open say, BASeBlock in VS2010 and jump in; I’m falling behind, after all (What with the aforementioned release of 2012 on the horizon). And VS2010 is definitely an improvement both tool and functionality wise over 2008, so there isn’t really a good reason not to switch now. No doubt I’ll keep making excuses for myself. Oh well.
At first, I thought I hated XNA; but now I know that what I actually hate is 3D programming. I imagine this is mostly because I got extremely rusty at it; additionally, I had never truly done 3-D programming, at least in the context of a game. My experience at that point was pretty much limited to the addition of 3-D graphic capabilities to a graphing application that I wrote (and never posted on my site because it hasn’t worked in ages, is old, and uses libraries/classes/modules I have updated that are no longer source compatible etc.). Of course that didn’t have constantly changing meshes, used DirectX7, and it was shortly after I had finished that feature that I abandoned the project, for whatever reason. I had never dealt with 3-D in a gaming capacity.
The purpose of XNA is to attempt to simplify the task of creating games- both 3D and 2D, for Windows as well as XBox 360. And it definitely does this; however you can really only simplify it so much, particularly when dealing with 3D Programming. My first quick XNA program was basically just to create a bunch of cubes stacked on one another. This is a very common theme given the popularity of games like Minecraft, but my goal was to eventually create a sorta 3-D version of Breakout (or, rather, BASeBlock 3D).
I was able to get the blocks visible, after a lot of cajoling, and doing the work on paper (Visualizing 3-D space and coordinates are not my forte). But it ran at 10fps! This was because I was adding every single block’s vertices to the VertexBuffer; for a set of blocks in a “standard” arrangement of, around 1920 blocks (which is probably a number that would make the 2-D version go around 10fps, to be absolutely fair here), that is over 11520 faces, each of which actually consist of a triangle list of 6 points (I tried a triangle fan but it didn’t seem to even exist (?), oh well) meaning that I was loading the VertexBuffer with over 69120 texture-mapped vertices. That’s a lot to process. The big issue here is Hidden Surface Removal; obviously, if we had a cube of blocks like this, we don’t need to add the vertices of blocks that aren’t visible. I’ll admit this is the part I sort of gave up on that project for the time being; that would involve quite a bit of matrix math to determine what faces were visible on each block, which ones needed to be added, etc based on the camera position, and I kind of like to understand what I’m doing, and I, quite honestly, don’t have a good grasp over how exactly Matrices are used in 3-D math, or dot products (at least in 3-D), and I prefer not to fly blind. So I’ve been reading a few 3-D programming books that cover all the basics; the book itself I believe goes through the creation of a full 3-D rasterization engine and has a lot of in-depth on the mathematics required; this, paired with concepts from Michael Abrash’s “Graphics Programming Black Book” should give me the tools to properly determine which blocks and faces should be added or omitted.
Anyway, scrapping that project for the time being, I decided to make something 2-D; but since I was more or less trying to learn some of the XNA basics, I didn’t want too much of the concepts of the game itself getting in the way, so I chose something simple- I just re-implemented BCDodger. I added features, and it runs much better this way, but the core concept is the same.
XNA is quite powerful- I have no doubt about that. Most of my issues with it are minor. One example is that XACT doesn’t seem to support anything other than WAV files, which is a bit of a pain; this is why BCDodgerX’s installer is over twice the size of BASeBlock’s, despite having far less content). Another minor peeve is that there is no real way to draw lines, or geometry; everything has to be a sprite. you can fake lines by stretching a 1×1 pixel as needed, but that just feels hacky to me. On the other hand, it’s probably pretty easy to wrap some of that up into a class or set of classes to handle “vector” drawing, so it’s probably just me being used to GDI+’s lush set of 2-D graphics capabilities. Another big problem I had was with keyboard input- that is, getting text entry “properly” without constant repeats and so forth. Normally, you would check if a key was down in Update(), and act accordingly. This didn’t work for text input for whatever reason, and when it did it was constrained to certain characters. I ended up overriding the Window Procedure and handling the Key events myself to get at Key input data as needed, then hooked those to actual events and managed the input that way.
Overall, I have to conclude that XNA is actually quite good. There are some intrinsic drawbacks- for example it isn’t cross platform (to Linux or OSX), and the aforementioned basic problems I had, which were probably just me adjusting my mindset. It’s obviously easier than using Managed DirectX yourself, or DirectX directly (if you’ll pardon the alliteration), and it is designed for Rapid creation of Games. With the exception of the High-Score entry (Which took a bit for me to get implemented properly) BCDodgerX was a single evening of work.
