示例1:
float
ParseKeyFrameTime( const float length, const Ogre::String& string )
{
float res = 0;
if( string.at( string.size() - 1 ) == '%' )
{
res = length * Ogre::StringConverter::parseReal( string.substr( 0, string.size() - 1 ) ) / 100;
}
else
{
res = Ogre::StringConverter::parseReal( string );
}
return res;
