 Posted: Sun Feb 24, 2008 10:16 am Post subject: Some differences between new plugin system and old one.... |
 |
|
Hi all,
while finishing my new C++ (VS8 and VS9 wizards and CodeBlocks) plugin interface I've noticed some differences between the old plugin architecture and the new one. In fact in the old plugin system you could pass just materials or objeccts or lights. In this one you need to pass a complete file structure everytime (including materials etc...), am I right? After some testes, in which I tried to pass (or update an object), I'm now convinced of this because if I pass the followin string (a simple cube to a clear scene):
| Code: |
<scene version="1.6">
<primitives highestID="1">
<primitive id="1" name="cube1" type="cube" visible="true" snap="vertex" autoUV="true" groupID="-1">
<vertices>
<vertex id="0" x="64" y="-64" z="0" />
<vertex id="1" x="-64" y="-64" z="0" />
<vertex id="2" x="-64" y="-64" z="-128" />
<vertex id="3" x="64" y="-64" z="-128" />
<vertex id="4" x="64" y="64" z="0" />
<vertex id="5" x="-64" y="64" z="0" />
<vertex id="6" x="-64" y="64" z="-128" />
<vertex id="7" x="64" y="64" z="-128" />
</vertices>
<polygons>
<poly mid="0">
<vertex vid="0" u0="0.5" v0="0.5" />
<vertex vid="1" u0="-0.5" v0="0.5" />
<vertex vid="5" u0="-0.5" v0="-0.5" />
<vertex vid="4" u0="0.5" v0="-0.5" />
</poly>
<poly mid="0">
<vertex vid="1" u0="0" v0="0.5" />
<vertex vid="2" u0="-1" v0="0.5" />
<vertex vid="6" u0="-1" v0="-0.5" />
<vertex vid="5" u0="0" v0="-0.5" />
</poly>
<poly mid="0">
<vertex vid="2" u0="0.5" v0="0.5" />
<vertex vid="3" u0="-0.5" v0="0.5" />
<vertex vid="7" u0="-0.5" v0="-0.5" />
<vertex vid="6" u0="0.5" v0="-0.5" />
</poly>
<poly mid="0">
<vertex vid="3" u0="1" v0="0.5" />
<vertex vid="0" u0="0" v0="0.5" />
<vertex vid="4" u0="0" v0="-0.5" />
<vertex vid="7" u0="1" v0="-0.5" />
</poly>
<poly mid="0">
<vertex vid="6" u0="-0.5" v0="-1" />
<vertex vid="7" u0="0.5" v0="-1" />
<vertex vid="4" u0="0.5" v0="0" />
<vertex vid="5" u0="-0.5" v0="0" />
</poly>
<poly mid="0">
<vertex vid="1" u0="-0.5" v0="0" />
<vertex vid="0" u0="0.5" v0="0" />
<vertex vid="3" u0="0.5" v0="1" />
<vertex vid="2" u0="-0.5" v0="1" />
</poly>
</polygons>
</primitive>
</primitives>
</scene>

When I pass this simple object I always obtain unexpected end of input. So for the moment exporter code works without problem but importer doesn't. I'm checking my plugin interface to find eventual bugs but nothing a t the moment found. If someone knows a little more about this, please let me know so I can release my new wizards for VS8 and VS9.
Bye all  |

| I'll investigate, this should just work. Thanks for reporting this reproduction case! |

The message "unexpected end of input" is just a technical (syntactical) error message from the xml scanner, most likely caused because there is whitespace at the end of your model (beyond the closing rootnode). It doesn't say anything about the (semantical) structure of the file.
When I copy pasted your example case I also got whitespace (a single space) at the end of my file, and had the exact same problem. After I removed the space, the cube imported just fine.
DeleD now trims incoming xml, so trailing and leading whitespace doesn't cause this problem anymore. However any text beyond the final rootnode will still cause this problem.
Hope that helps! 
[edit]Oh, before I forget, it's very good to hear you are working on your C++ plugin interface again... exciting stuff![/edit] |

Thanks Paul-Jan,
I've just solved removing "\n" after the closing scene tag.
So expect a release soon.
I'll try with Visual Studio Express 2008 too.

| Can hardly wait! I am actually starting work on a Visual Studio C++ plugin too (because the libraries for this particular file format are readily available in C++), so any work I can pinch of you (and Jon Watte) helps me out! |

Hi Paul-Jan,
I can send you the work in progress code (it works ok, I need just a little time to create wizard for Visual C++ ).
Anyway, if you can wait I'll deliver wizard to the community in 10 days more or less (I hope less, but I'm very busy at the moment cause I'll leave Italy 31st of March).
Bye
P.S.: I'm also trying to figure out if license for xmlParser (BSD) agrees with my license (GNU) or I need to change it. Suggestions welcome. |
