Is there a way to show the mesh of collision object? So I can check the size with the model?

OgreNewt::Debugger.

read about it in the documentation, it's very easy to use.

Where's the documentation? It doesn't come with the CVS....

you need to use DOXYGEN to generate the source for the CVS version, there is a DOXYGEN file in there to make generating the docs easy.

or just look at the comments in the OgreNewt_Debugger.h file :)

tried it:

OgreNewt::Debugger::init(mSceneMgr);
OgreNewt::Debugger::showLines(m_World);
OgreNewt::Debugger::hideLines();

but

Error 2 error C2352: 'OgreNewt::Debugger::init' : illegal call of non-static member function c:\eindwerk\Ogre\ogreaddons\OgreNewt\demos\Demo01_TheBasics\OgreNewtonApplication.cpp 94
Error 3 error C3861: 'showLines': identifier not found c:\eindwerk\Ogre\ogreaddons\OgreNewt\demos\Demo01_TheBasics\OgreNewtonApplication.cpp 96

misterface, the debugger functions are not static, as the compiler tells you. See the OgreNewt examples for how to use it correctly.

:oops: sorry but I can't implement it in my project.
I can open the file in the examples, but I can't implement it. Somebody that can help me?
wish I was much better in c++ :)

OgreNewt::Debugger::getSingleton().init( mSceneMgr );
OgreNewt::Debugger::getSingleton().drawLines( mWorld );

Are you calling OgreNew::Debugger::getSingleton().init() multiple times? Perhaps in your frameStarted? If so, only call it once when you initialize your app.

Also, getSingleton() returns the singleton object reference for the Debugger object. Google for "singleton pattern" to learn about singletons and their use in object oriented systems.

1) thx, understanding the singleton thing :)
2) I only call it once I think, i'm using Demo01_TheBasics, looked everywhere in the code and I don't see the method is called anywhere.

the debugger is built-in to the OgreNewt::BasicFrameListener class. just hit F3 in any of the demos to see the debug lines.

you can see how it works be looking at the code for the BasicFrameListener.
