Congratulations on involving OSX into the AGen builds. I want to try AGen out at some point.

Me too, but I will have to wait for the linux version...

Hey everybody this is not Love2D-related but I hope the mods won't be too upset.
We have a Linux build of the engine, but before we can release it, we need some feedback from Linux gamers.
There is an experimental Linux build of one of our games:
http://2dengine.com/commando/8Bit_Comma ... 86.tar.bz2
Please try it out and let me know if you experience any issues.

Dependencies:
- audio: ogg/vorbis and openAL
- gamepads: SDL
- graphics: openGL

It can be extracted in a private directory or under /usr or /usr/local. Thanks so much!

Works perfectly for me, even with gamepads.
The only issue I have is with video mode changing. When setting from windowed to fullscreen, and then do windowed again, i get:

Another video issue is when changing resolution: when changinx from 800x600 to the next 1024x768, everything is OK. But then whanging to the next one 1600x900 displays options menu for a fraction of second, then the screen becomes black (music continues to play). Pressing ENTER again does not do anything (like changing resolution once more).

Anyways, those are minor issues. The game is perfectly playable.

Edit:
After playing a little longer, I found a critical error. It happens at the same place every time (after the second plane), the application crashes with floating point exception, related to Box2D. Here is gdb backtrace:

It ran really well w/ controller on my archbox as well;

Linux seppi7 3.8.10-1-ARCH #1 SMP PREEMPT Sat Apr 27 12:36:59 CEST 2013 x86_64 GNU/Linux

After a while, I got this;

Sorry to bump an old topic but check it out, we've just released our Box2D editor:
http://2dengine.com/bin/release/boxy.1.3.10.zip

It can output and load XML files (using its own schema).
I tried to program a Love2D loader but couldn't get LuaXML to work properly with Love2D.
Basically, you need a script that can iterate the XML file and that creates corresponding bodies/shapes in Love2D.
A triangulation lib may be necessary to decompose concave polygons.
Oh ya, and the editor only supports 3-4 basic joints types but it's sufficient to make some pretty sweet physics levels.

if anyone wants cross platform 3D lua engine there is always source engine (or what i call it: sauce engine)

Posted: **Sun Nov 24, 2013 7:03 am**

all this time i thought source used lua as the main language.... all this time

Hey everybody, I need some help with a non-love2d project.
Would be very greatful if anybody with Windows 8 (on a multitouch device) would run the following test:
http://2dengine.com/ftm/multitouch.zip
Just extract and run "agen.exe" then you will be see a black screen saying "multitouch test".
The point is to try and see if multitouch input works at all.
Just make contact with the two or more fingers and see if it's detected.
Much appreciated if anybody could confirm that it works!
Thanks so much.

I'm not sure what was supposed to do when touched with more than one finger, but here's what I got:
- Horizontal sliding- Makes little arrow pointing side-to-side. Works with 2+ fingers.
- Vertical sliding- Makes little vertical arrow. Works with 2 finger, not 3. Didn't test any further.
- No diagonal or other movements detected.
