2.6.2 to 3.0.0 sf::Vertex AchseV[]

[HeinzK]

 After I edited some 100 places with sf::Vertex ...
 //> 2.6.2

 k_Vertexs.push_back
           (
             sf::Vertex
                 (
                   sf::Vector2f(fX1, fY1),
                   CoZ
                 )
           );

 //> 3.0.0

 k_Vertexs.push_back
           (
             {
               sf::Vector2f(fX1, fY1),
               CoZ
             }
           );

... I hope this is correct? (Unfortunately, I can only test it again once everything has been 'translated'!),

I have come across a problem!

//> 2.6.2

sf::Vertex AchseV[] =
{
  sf::Vertex(sf::Vector2f(0.0, 0.0)),
  sf::Vertex(sf::Vector2f(0.0, 0.0))
};

//> 3.0.0

sf::Vertex AchseV[] =
{
  sf::Vector2f({0.0, 0.0}),
  sf::Vector2f({0.0, 0.0})
};
...
AchseV[0].position.x = (float)k_pMaus->GetlMausX();
pWindow->draw(AchseV, 2, sf::Lines);
...

How will this be solved in 3.0.0?

Code:

if
  (
    (pWindow != NULL)
    &&
    (k_pMaus->GetbMausImWindow() == true)
  )
  {
    sf::IntRect View = pWindow->getViewport(pWindow->getView());

    sf::Vertex AchseV[] =
    {
      sf::Vertex(sf::Vector2f(0.0, 0.0)),
      sf::Vertex(sf::Vector2f(0.0, 0.0))
    };

    sf::Vertex AchseH[] =
    {
      sf::Vertex(sf::Vector2f(0.0, 0.0)),
      sf::Vertex(sf::Vector2f(0.0, 0.0))
    };

    AchseV[0].position.x = (float)k_pMaus->GetlMausX();
    AchseV[0].position.y = (float)(View.top + View.height);
    AchseV[1].position.x = (float)k_pMaus->GetlMausX();
    AchseV[1].position.y = (float)View.top;

    AchseV[0].color = sf::Color(127, 127, 127, 150);

    AchseH[0].position.x = (float)(View.left + View.width);
    AchseH[0].position.y = (float)k_pMaus->GetlMausY();
    AchseH[1].position.x = (float)View.left;
    AchseH[1].position.y = (float)k_pMaus->GetlMausY();

    AchseH[0].color = sf::Color(127, 127, 127, 150);

    if (true) //> vorab .. bis .. s.u.:
    {
      pWindow->draw(AchseV, 2, sf::Lines);
      pWindow->draw(AchseH, 2, sf::Lines);

    } else
    {
      /// pZeichnen->AddObjekt_Line_SFML(....);  //> muss noch programmiert werden:

    }
  }

You can use aggregate initialization like this:

sf::Vertex AchseV[] =
{
  { sf::Vector2f(0.f, 0.f) },
  { sf::Vector2f(0.f, 0.f) }
};

Thank you very much, but wy not:
sf::Vertex AchseV[] =
{
  { sf::Vector2f({0.0, 0.0}) },
  { sf::Vector2f({0.0, 0.0}) }
};

[eXpl0it3r]

The inner {0.0, 0.0} will create a sf::Vector2<double> instance, which you then pass to the sf::Vector2f constructor. The compiler will likely optimize this away, but it's completely redundant.

So it's better to directly call the sf::Vector2f constructor with float values.

[HeinzK]

Understood.
My next problem.
2.6.2
sf::IntRect View = pWindow->getViewport(pWindow->getView());
AxisV[0].position.y = (float)(View.top + View.height);
3.0.0 there is now sf::View ... so:
sf::IntRect Vw = pWindow->getViewport(pWindow->getView());
AxisV[0].position.y = (float)(Vw.top + Vw.height);
.. but this does not work (.top und .height not available)
.. please help.

You can check the migration guide for all the changes needed.

sf::Rect has changed and now offers position and size as properties, size contains the x and y properties

[HeinzK]

I work with the migration guide. I anderstood:
v2: sf::IntRect rect(250, 400, 50, 100);
v3: sf::IntRect rect({250, 400}, {50, 100});
.. but I don't find the 'width' and 'height' properties.

[eXpl0it3r]

Sorry, I derped size and position are vector2 instances, so you get x and y

width = size.x
height = size.y
