Hi guys,
Strange bug with osgText, with the current configuration:
std::string fontName = "../data/Vera.ttf";
VarsEditor::instance()->get("fontPlayerName", fontName);
osgText::Font* font = osgText::readFontFile(fontName.c_str());
_seatNumber->setFont(font);
_seatNumber->setCharacterSize(25);
_seatNumber->setCharacterSizeMode(osgText::Text::SCREEN_COORDS);
_seatNumber->setAlignment(osgText::Text::CENTER_CENTER);
_seatNumber->setFontResolution(30,30);
_seatNumber->setAxisAlignment(osgText::Text::SCREEN);
std::stringstream ss;
ss << "Seat " << data._seatNumber;
_seatNumber->setText(ss.str());
I added a video because i don't how to explain it. A text should be
display and it is not, it's a bit random, sometimes it works
sometime it does not. I dump the osg tree and the osgText was in the
file, then if i re read the file with osgviewer it works.
I found a trick to make it display again in my application, moving the
camera very near, then it appears. I don't have any idea appart accusing
osgText.
I tried in SingleThreaded and the problem and it does not change.
I guess it's related to the camera position when i create the text.
Because i susupect that, i tried a configuration
std::string fontName = "../data/Vera.ttf";
VarsEditor::instance()->get("fontPlayerName", fontName);
osgText::Font* font = osgText::readFontFile(fontName.c_str());
_seatNumber->setFont(font);
_seatNumber->setCharacterSize(0.25);
// _seatNumber->setCharacterSizeMode(osgText::Text::SCREEN_COORDS);
_seatNumber->setAlignment(osgText::Text::CENTER_CENTER);
_seatNumber->setFontResolution(30,30);
_seatNumber->setAxisAlignment(osgText::Text::SCREEN);
std::stringstream ss;
ss << "Seat " << data._seatNumber;
_seatNumber->setText(ss.str());
So the character size mode is now the default, and with that i cant
reproduce the bug. So last information i have is when i create the text
the text is behind the camera
so maybe it does not help for the
_seatNumber->setCharacterSizeMode(osgText::Text::SCREEN_COORDS) mode.
