General / Rotating a Sprite

« on: June 25, 2013, 11:59:51 pm »

I'm having problems with this, I have a Ship class, that inherits the Sprite class... I change It's origin to the center, but if I try to rotate the Sprite, It's seems like it rotates the sprite from the top-left corner, there's my code:

Ship::Ship()
    : sf::Sprite()
{
   texture.loadFromFile("10B.png");
   this->setTexture(texture);
 
   this->setOrigin( this->getGlobalBounds().width / 2, this->getGlobalBounds().height / 2 );
   this->scale(sf::Vector2f(0.25f, 0.25f));   
   this->setPosition(100.0f, 100.0f);
 
   // Definimos la velocidad
   this->speed.x = 300.0f;
   this->speed.y = 300.0f;

}
 
void Ship::update(sf::Time& delta)
{   
   float left = this->getPosition().x;
   float right = this->getPosition().x + this->getGlobalBounds().width;
   float top = this->getPosition().y;
   float bottom = this->getPosition().y + this->getGlobalBounds().height;

   if (sf::Keyboard::isKeyPressed(sf::Keyboard::Up) && top > 0)
      //this->setRotation(this->getRotation() + 5);
      this->move(0.0f, -delta.asSeconds() * speed.y);
   if (sf::Keyboard::isKeyPressed(sf::Keyboard::Down))
      this->move(0.0f, delta.asSeconds() * speed.y);
   if (sf::Keyboard::isKeyPressed(sf::Keyboard::Left) && left > 0)
      this->move(-delta.asSeconds() * speed.x, 0.0f);
   if (sf::Keyboard::isKeyPressed(sf::Keyboard::Right))
      this->move(delta.asSeconds() * speed.x, 0.0f);

   if (sf::Keyboard::isKeyPressed(sf::Keyboard::A))
      this->rotate(5);

   if( top < 0 )
   {
      this->setPosition( this->getPosition().x, 0 );
   }
   if( left < 0 )
   {
      this->setPosition( 0, this->getPosition().y );
   }
    
}

General / Having problems on 64 bits

« on: June 22, 2013, 05:05:26 pm »

I'm having some problems running SFML on 64 bits, the thing is, when I try to render text, the console shows this message:

An internal OpenGL call failed in Texture.cpp <327> : GL_INVALID_VALUE, a numeric argument is out of range

and It doesn't show any text...

Otherwise, the fps seems crazy, even with "Vertical Sync" enabled. I test exactly the same code on my desktop pc and It works perfectly.

These are my laptop's specifications:

Graphics / Can't draw text and either load font

« on: June 21, 2013, 02:45:48 am »

I'm trying to draw some text to a game, but I'm having trouble with it.




<sub>#include <SFML\Graphics.hpp>

sf::Font font;

int main()
{
   sf::RenderWindow window( sf::VideoMode( 800, 600 ), "Texto" );

   font.loadFromFile("BROADW.ttf");

   sf::Text text;
   text.setFont(font);
   text.setCharacterSize(40);
   text.setColor(sf::Color::Blue);
   text.setPosition( 100.0f, 100.0f );
   text.setString( "Hola Mundo!" );

   while (window.isOpen())
    {
        // check all the window's events that were triggered since the last iteration of the loop
        sf::Event event;
        while (window.pollEvent(event))
        {
         if (event.type == sf::Event::Closed)
                window.close();
        }

      window.clear( sf::Color::Black );
      window.draw(text);
      window.display();
   }

   return 0;
}</sub>




When I try to load the font, I'm getting this error: "Unhandled exception in 0x66c41f34 (msvcr100.dll) in Text.exe: 0xC0000005: Access violation reading location 0x00357000."
Even if I try to draw text without font, It doesn't draw anything. What's going on?
