This looks really great. This is what I tried with my game engine aroma, http://leafo.net/aroma/ but I gave up before implementing all of love's api. (love didn't use es 2.0 when I started the project so I was essentially rewriting love from scratch). I'll give yours a shot with running my ludum dare games.

When I wrote aroma I noticed that the nacl opengl drawing performance was pretty bad. Drawing operations were maybe a 10th of what love standard was getting. Did you notice this at all? This was kind of depressing, I was about to ditch nacl and try developing a more traditional browser plugin. It was only drawing operations, lua itself ran about the same speed.

Anyway, great job! I was really excited when I learned slime was porting love to es 2 because I knew this would come out of it.

There's a lot of potential for doing cool stuff with this. I even integrated google analytics into my engine so I could track game events directly from Lua. :cool:

You have to be careful with glGet*, those take a really long time to run because they're not asynchronous. Usually if you're seeing low framerate where you expect more, try remove all your glGetError calls. That often produces a nice speedup! :)

Totally agree, mostly I just wanted to get this out there so people could play with it and give feedback... but I have a few ideas about how to make this a pretty slick experience. :D

Looking pretty good. Is there a list of unsupported features anywhere? So far I see #include in the shader compiler and stencils are missing?

Stencils work. #include in shaders was removed shortly after 0.8.0 was released, for whatever reason. It didn't work as people might expect, anyway.
ColorModes don't work in OpenGL ES 2, but they aren't useful anyway so that's okay (they're also being removed for 0.9.0) - everything that can be done with setColorMode can be done with setColor or Shaders.

I've only done a bit of testing of the ES2 stuff on iOS, so it's good to see (your version of it) works with most games. :)

Guys, this is awesome news! :D Thank you for your work!

So does this mean that we can run LÖVE games on IPhone, IPad, Android in addition to Linux, Windows and Mac?
Do you have a list of features or limitations somewhere?

I'm going to test this asap in my Chrome on Linux.

Wow, it really works! :) I'm testin it on Linux Mint 13 (Ubuntu based), Chrome version 26.0.1410.63.

- I did not have to turn on that Native flag.
- Mouse pointer is misplaced in Metaballs example (probably due to that the LÖVE window is placed to the middle of the browser window).
- It seems to be fast!
- It plays sound and music!
- Mousewheel does not work in Particles example.
- Sinescroller example is laggier than the original, at least here.
- Games load quickly!
- Ortho Robot was a little bit slower but Mari0 and IYFCT run just fine.
- Mouse aiming is all right in Mari0.
- Printing text seems to be slow.

I really like it! :)

Unfortunately, Native Client only runs on desktop Chrome -- that means, Linux, Windows, Mac, ChromeOS only.

I'm tracking bugs on the github page. Off the top of my head, the major limitations right now are: love 0.8 only, no persistent storage, no luasocket.

I haven't done extensive testing, but most .love files should work. Some require modifying the shaders (for example the Snayke demo). If you find some that are completely broken, please file a bug!

I remember that in the webplayer he (we? I seem to remember playing a role in this bit) eventually used localStorage to simulate a filesystem, is this not possible from NaCl, too?

Definitely possible, I just haven't implemented it yet. :D

More technical info: NaCl can access the html5 filesystem, which supports a persistent store. The trouble is that love2d uses physfs, which expects to be able to call readdir() and stat() on a directory, which isn't currently supported by the Native Client API (it's currently being implemented). There are ways to work around this, but none are trivial (and I kinda wanted to get this out there... ^^ )

Ah, I see! Still really awesome! :) Thanks for the link, I'll definately keep an eye on this project.
