Graphics / sf::Text::draw() renders squares instead of text, regardless of font being used
« on: December 27, 2012, 07:33:20 pm »
Hi, I just compiled SFML 2.0 from source and am dynamically linking the libraries.
Currently, all I've really been doing is playing with the API in hopes to make a basic Asteroids game. The main issue I'm having though is trying to understand what could be causing this issue, as the sf::Text is being rendered squares and not as actual text. I've tried using different fonts, loading the font object itself differently, setting different char sizes; sf::Colors; sf::BlendModes, etc and none of that has worked.
To give you an example, I'll post some code.
At first, there is a utility function which simply performs the following:
In the main game class, the font is loaded like so at the beginning of execution:
And then the code to actually draw the text resides in a simple function ( DrawText() ):
And, as a result, I get the following:
Please note that sf::RenderStates::Default returns a linker error, hence why I'm embedding a sf::RenderStates option within the mWindow.draw().
Also, I should also say that I compiled this to be used with MSVC 2012. I'm not sure if I need to link with FreeType font library as well for this to work, so if any clarification with that could be made, I'd appreciate it.
Thanks.

At first, there is a utility function which simply performs the following:
void LoadFont( const std::string& fontname, sf::Font& out_font )
{
const std::string fullpath = "assets/fonts/" + fontname;
if ( !out_font.loadFromFile( fullpath ) )
ErrorQuit( "loading font \"" + fullpath + "\" failed." );
}
{
const std::string fullpath = "assets/fonts/" + fontname;
if ( !out_font.loadFromFile( fullpath ) )
ErrorQuit( "loading font \"" + fullpath + "\" failed." );
}
In the main game class, the font is loaded like so at the beginning of execution:
LoadFont( "arial.ttf", mMainFont );
And then the code to actually draw the text resides in a simple function ( DrawText() ):
void Game::DrawText( void )
{
// Draw current mouse coordinates:
sf::Vector2i mousepos = sf::Mouse::getPosition( mWindow );
sf::Text out;
out.setFont( mMainFont );
out.setCharacterSize( 30 );
out.setColor( sf::Color( 255, 255, 0, 0 ) );
out.setPosition( 20.0f, 20.0f );
std::ostringstream oss;
oss << "Mouse X => " << mousepos.x << "\n Mouse Y => " << mousepos.y;
out.setString( oss.str() );
mWindow.draw( out, sf::RenderStates( sf::BlendMode::BlendNone ) );
}
{
// Draw current mouse coordinates:
sf::Vector2i mousepos = sf::Mouse::getPosition( mWindow );
sf::Text out;
out.setFont( mMainFont );
out.setCharacterSize( 30 );
out.setColor( sf::Color( 255, 255, 0, 0 ) );
out.setPosition( 20.0f, 20.0f );
std::ostringstream oss;
oss << "Mouse X => " << mousepos.x << "\n Mouse Y => " << mousepos.y;
out.setString( oss.str() );
mWindow.draw( out, sf::RenderStates( sf::BlendMode::BlendNone ) );
}
