Unimplemented XNA / LINQ Methods

[BrainSlugs83]

Hey, I found a closed issue from a while back issue #128 -- I put a comment there since the discussion seemed related, but since it's old and closed I'm not sure if you'll ever see it or not.

(I'm new to GitHub, and I feel a little bad submitting all these new issues in serial, but I legitimately want to help and also to make JSIL work for me, this project is awesome. I might also be able to take a crack at some of this myself and submit patches if you want to give me some guidance on that...)

Specifically, I'm running into the following unimplemented methods (but from what I can tell of the conversation on issue #128 it sounds like a couple of them should be implemented? I'm not sure. Specific the "get_PreferredBackBufferWidth" and "get_PreferredBackBufferHeight" ones...)

Anyway, a couple of them can probably be ignored like the set_PreferredBackBufferFormat, but a couple of them are causing some major issues for my project (the LINQ one especially).

Most of those don't look like a problem - I'll look into the others.

Does your game use 3d? JSIL doesn't support 3d yet. -kg (mobile)

Well, it's pretty much all 2D, I do do some line/triangle drawing with BasicEffect after I do my SpriteBatch stuff, but I could try to find another way to implement those -- or again, with guidance (I'm not sure where your javascript implementations live, I haven't really looked around yet) I could just go learn 3D WebGL and start implementing some of that stuff and I could submit some patches for it, maybe?

As for my game, the source is online [see below], it's not even close to finished yet (it's more like an unfinished engine at this point) -- but I was hoping to make JSIL the target platform -- that way, on PC, you wouldn't have to install it, and on mac/linux you wouldn't have to worry about mono-game, etc...

Also, I was thinking... JSIL supports SilverLight, right? Some people have done some demos where they write code in a hidden SilverLight control which then renders to an HTML canvas element... maybe I could look into porting my game to SilverLight if you think that would work better with JSIL. (Again, the idea being that end users wouldn't have to download / install anything -- or grant permission to SilverLight for 3D rendering, etc..)

[Source:] As for the "game" itself, it was an unfinished LudumDare 27 entry that I'm kind of excited about continuing in my spare time going forward -- again, it's super unfinished, and more like a barebones demo, atm, but you can see some screenshots, download the bins / source files here: http://www.ludumdare.com/compo/ludum-dare-27/?action=preview&uid=22701

If you want to build the source, here are a few things you'll need:

• Download the "Source (newer)" file -- the older one has unneccessary stuff in it that freaked out JSIL a little bit "(newer)" has specific mods in it to work better with JSIL.
• It's a Visual Studio 2012, XNA 4.0 project -- this is not something that normally works -- to get it to open you have to copy your XNA 4.0 2010 project template to the 2012 folder and add a node that says Visual Studio 2012 is supported. [ It's pretty easy to do this. See this SO article for details: http://stackoverflow.com/questions/10881005/how-to-install-xna-game-studio-on-visual-studio-2012 ]
• The solution contains a fully integrated setup.exe project -- I tried to tell JSILc to ignore it in my .jsilconfig -- but it still crashes (did I do it wrong?). If you remove the two WiX setup projects, it will get past this point. -- (I have modified my own version of JSILc with a minor code change to make it ignore non-.net .exe/.dll files -- I have no idea how to make or submit a patch though -- I'm more of a TFS person than a GIT person. -- I was planning on looking into figuring out patch-creation/submittal this weekend.) -- [ submitted a pull request with the fix for this one, see #261 ]
• The solution contains an ASP.NET web project for the JSILc output as well. This also causes JSIL to choke, because it finds two instances of the XNA assets and considers that ambiguous -- you can remove this project from the solution as well, and JSILc should just work. (again, I've modified my version to work with this -- if it finds more than one asset location, it checks to see if any of them are in the same directory as the output directory and removes those ones from the array.) -- [ submitted a pull request with the fix for this one, see #262 ]

This should get your game past those errors.

FYI, JSIL does not have any built in Silverlight support. A contributor was experimenting with that but I don't think anything ever came of it.

Nice. Thanks for putting those in! I put in some temp fixes to get around those issues, I'll roll those back out and see what happens. :-)
