Title: modifying old code
Post by: TwoFingeredPointer on August 31, 2015, 01:42:17 am

Hello all. I have recently started playing around with SFML. I have found an excellent tutorial online and I am working through it. The tutorial was written for version 1.6 to be used for microsoft  visual 2010. However I am using microsoft visual 2013 and i have installed version 2.3.1 I have been modifying the code and all seems to to work reasonably well. However I am stuck with these lines of code here:

 void PlayerPaddle::Update(float elapsedTime)
{

   if (Game::GetInput().IsKeyDown(sf::Keyboard::Left))
   {
      _velocity -= 3.0f;
   }
   if (Game::GetInput().IsKeyDown(sf::Keyboard::Right))
   {
      _velocity += 3.0f;
   }

   if (Game::GetInput().IsKeyDown(sf::Keyboard::Down))
   {
      _velocity = 0.0f;
   }

   if (_velocity > _maxVelocity)
      _velocity = _maxVelocity;

   if (_velocity < -_maxVelocity)
      _velocity = -_maxVelocity;


   sf::Vector2f pos = this->GetPosition();

   if (pos.x  < GetSprite().GetSize().x / 2
      || pos.x >(Game::SCREEN_WIDTH - GetSprite().GetSize().x / 2))
   {
      _velocity = -_velocity; // Bounce by current velocity in opposite direction
   }

   GetSprite().Move(_velocity * elapsedTime, 0);
}


I am reading through the documentation in order to create a suitable modification. But in order to speed up my build does anybody have an existing solution to this. Has this problem been solved already?

A solution to what? I don't see any problem, apart from following a tutorial for a very old version of SFML.
Use sf::Keyboard? Read the 2.3 tutorials? Or search (http://en.sfml-dev.org/forums/index.php?topic=5817.msg44468#msg44468)?

You have already posted a thread (http://en.sfml-dev.org/forums/index.php?topic=18886) about this old tutorial and converting it to the new version of SFML. Are the official SFML tutorials (http://www.sfml-dev.org/tutorials) not enough?

You must think that this 1.6 tutorial has something that others do not. Would it be possible for you to inform us which tutorial you are using?
