This sounds exciting!

This does sound exciting. 

Lua syntax highlighting is something I've been wishing I could "plugin" to 
Blender, so this will be a nice addition. Especially once we get the ability to 
link multiple blends into the one game (perhaps through linked script).

That said, I would add another feature, that being the ability to SAVE Lua 
script back into a blend file (as a text block, as per standard Blender). The 
reason I say this is that OgreKit is getting a reasonable reputation amongst 
some of the indie/open source crowds now, so being able to "polish" a demo 
using this tool and run it out of the box using OgreKit would be pretty damned 
good publicity (not to mention cool in it's own right).

Yes this seems great.

For text editing http://www.scintilla.org/ might be usefull it is MIT licensed, 
claims to be lightweight and working on Windows Mac OSX and Linux.

For the use of EmbedDemo, I suppose it would be good to clean it's code a 
little to make it mor reusable. Maybe writing a custom wxWidget that can be 
reused by both app (and pretty much any wxWidgets app).

Thanks for yours interesting. 

I think also, BGE user don't easy to use Ogrekit.
And, if we can make the modulable blend file, it will useful to everyone.

Ok, add to todo list.
- insert the lua file to the blend file's text block at distribution.

The scintilla is not part of Ogrekit build, but it is already included in the 
wxWidgets.  Of course, I will use it.

EmbedDemo code will be shared both project. so, this code will be clean up in 
the progress.

I was not aware that Scitilla was operational on Mac OSX (the official website 
indicated otherwise). Is this something that has been shown to work via 
wxWidgets?

Yes OSX support is not advertised but there are bug corrections for OSX in 
their changelog. There is also a Syntilla-cocoa project. This seems a little 
more complicated then for other platform but it still is the more "portable" 
solution I found.

This project is using scintilla for Win Linux and Mac (but does not uses 
wxWidgets)

wxStEdit is a library and sample program for the wxWidgets's wxStyledTextCtrl 
wrapper around the Scintilla text editor widget.

It seems, wxStEdit has merged to main trunk one year ago.

and I tested wxWidgets 2.9.1 on OSX, the stctest sample working fine.
so, you should not worry about that.

[GoogleCodeExporter]

Excellent - thanks. I've actually been a little frustrated developing Lua / PHP 
code on the OSX machine because of a lack of Scite (there is a Darwin port, but 
frankly it sucks hosting everything in X11 on the MacPro).

Will take the word of more informed developers on this :)

I have little progress. 
Scintilla module(wxStyledTextCtrl) is integrated to Ogrekit wxWidgets build.

I call it a big progress (so quick!).
Good job.
It´s looking good!

In the oft-repeated words of Bill & Ted... "Dude!"

Is this coming close on a check in (I didn't see a new version in the GameKit 
updates)?

Thanks, but above screenshot is just for window layout job.
There is not much working.
If minimal functions is implemented, I will commit to trunk.

I will try to release the first version for windows in this month,
but it will be barely working. :)

Fantastic work!
I cant wait for the release of the first version.

Original comment by germanov...@gmail.com on 21 Oct 2010 at 6:54

[GoogleCodeExporter]

Very eagerly looking forward to this. The demo looks pretty exciting too.

I assume you'll be checking in the code, not just uploading a windows binary?

Original comment by BenT.Sol...@gmail.com on 21 Oct 2010 at 6:55

[GoogleCodeExporter]

I will upload source & binary, both.

I bring some code from my other ogre3d project.
So, I should clean up the source code before commit to svn trunk.

Thanks for waiting. I committed LuaEditor source to r755.
It still has lack of integration with LuaRuntime/Blend File/Help.
Next update will focus on this.

Will LUA Scripting perform at run-time inside the editor (like changing 
animations when the game is running inside the editor)?

Original comment by germanov...@gmail.com on 5 Nov 2010 at 7:35

[GoogleCodeExporter]

If Lua console is interactive with GameEngine, it is nice.
but I'm not sure, animation preview will be supported this way.

Hi all,

I've built gamekit (Ubuntu 10.4 / Gnome) from trunk but I'm not able to run 
AppLuaEditor.

I've got error message:

The program 'AppLuaEditor' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 21 error_code 3 request_code 3 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
AL lib: ALc.c:1879: exit(): closing 1 Device
AL lib: ALc.c:1808: alcCloseDevice(): destroying 1 Context(s)

btw.
Running with 'xtrace' I got following error:

000:>:16ff:32: Reply to GetInputFocus: revert-to=Parent(0x02) focus=0x03800005

Is anyone experiencing this error? Any suggestions?

Thanks for reporting, Mirza.

How about EmbedDemo sample,  it isn't working, too?
EmbedDemo, LuaEditor has shared code for window setup.
Unfortunately, I can only build test on Linux VM.

Hi harkon,

I got this error by running EmbedDemo:

*** glibc detected *** /home/mirza/src/gamekit/Samples/EmbedDemo/AppEmbedDemo: 
double free or corruption (fasttop): 0x09a30638 ***

It seems that there is a memory corruption.
I've attached back-trace.

btw. Sporadically I'm able to run EmbedDemo but it crashes whenever I try to 
load new .blend file.

About "Support distribution with LuaRuntime", are you planning to integrate 
LuaJIT in the LuaEditor using the jit API (http://luajit.org/ext_jit.html) to 
build a distribuable version of a prototype/possible game?

You could also include something like LuaSrcDiet to reduce the main script size 
and give a little obfuscation to it, not to the original script of course, but 
as another script or as an embedded script. This could be useful for 
distribution both for adding some speed and security improvement.
