Hey all,<br>
<br>
for claryfication ... I can read write armatures in the GE now?!<br>
This is what I understood from the last mails :)<br>
<br>
My goal is to write a time triggered script which manipulates the
armature.<br>
<br>
Benoit - if so, can you provide us with some sample code?<br>
<br>
BTW: You build works fine on Ubuntu (32Bit) ) 9.04<br>
<br>
<br>
Cheers, Florian<br>

<pre wrap="">Blender 2.5 needs Python 3.1 indeed (at least the GE).
Regarding Blender module, yes it's gone, you need to switch to the new
RNA and operator API.
You have the documentation (still partial) here :
<a class="moz-txt-link-freetext" href="http://www.graphicall.org/ftp/ideasman42/html/bpy-module.html">http://www.graphicall.org/ftp/ideasman42/html/bpy-module.html</a>
The principle is that you get reference to the data block you want to
manipulate from the context
(<a class="moz-txt-link-freetext" href="http://www.graphicall.org/ftp/ideasman42/html/bpy.types.Context-class.h">http://www.graphicall.org/ftp/ideasman42/html/bpy.types.Context-class.h</a>
tml): you start from the main and dig through it.
Afaik it's not available in the GE yet.
So in the GE you must stick with GE API only, which hasn't changed.
You will noticed that I implemented proxy classes in the GE to bone,
pose channel, and armatures. So you don't need bpy for that.
I hope this news are not too disappointing ;-)

Benoit

Hi Benoit,
I figured out some other problems now. I got Blender to compile only
with Pyhton 3.1 but now I cannot use my scripts anymore with
the error:
Traceback (most recent call last):
File "Steuerung.py", line 4, in <module>
ImportError: No module named Blender
Do you know what this could be or is there already a
documentation for 2.5?
Thanks,
Markus

Hi,
I just managed it to compile the branch with the ikplugin. For some
reasons I was not able to compile because of a few errors. I
think its
just some little changes in the CMake files. First of all the
BIK_api.h
was not found. I did it quick and dirty by copying the full
path in the
files where it is needed. The second thing was that obviously
the libs
bf_ikplugin and bf_ITASC are not in the list of libs to link
against. Maybe you did not update the CMakeList or was it a
problem of my computer?
Regards,
Markus
