and downloaded the binary in this link:
http://www.weltenspiegel.de/private/ogre/cegui/20050215/font_futech.zip
My first test is trying to use this bitmap font in my own code and there lies the problem. Here is a snippet of the code I use:
Code: Select all
mGUISystem = new CEGUI::System(mGUIRenderer);
CEGUI::Logger::getSingleton().setLoggingLevel(CEGUI::Informative);
CEGUI::SchemeManager::getSingleton().loadScheme((CEGUI::utf8*)"TaharezLook.scheme");
mGUISystem->setDefaultMouseCursor((CEGUI::utf8*)"TaharezLook", (CEGUI::utf8*)"MouseArrow");
mGUISystem->setDefaultFont("Futech9");
Simple stuff really. However, it doesn't even get to the point where the default font is set and I get a debug assertion like so..
looking into the local variables in the debugger it seems there is a problem somewhere in the XML parser for the font.
Looking at CEGUI.log it appears that the TTF fonts are generated normally but the bitmap chokes:

</GUIScheme>Since this particular font is working correctly in the binary from the 2nd link I take it the problem must lie in the version of CEGUI that I use (Ogre 1.0.7/CEGUI 0.4(?). I also tried using this particular font with the Demo_GUI from the Ogre sources (thinking it might be an issue with my project) but I get the same error.
Is there a different way to implement bitmap fonts for the version of CEGUI that is included with Ogre source 1.0.7? Is perhaps the Font.xsd different and therefore the XML parser for FontManager crashes because of that?
Please if someone knows how to work with bitmap fonts in Ogre 1.0.6-1.0.7 and can help with this I would be ecstatic
