Texture to a rectangle

[AlexxanderX]

I have soprems setting to a  renctangle the texture:

     sf::Texture texture;
        if (!texture.loadFromFile("resources/backgroundimage.png"))
     return -1;

    // Jucatorul din stanga
    sf::RectangleShape leftPaddle;
    leftPaddle.setSize(paddleSize - sf::Vector2f(3, 3));
    leftPaddle.setOutlineThickness(3);
    leftPaddle.setTexture(texture);
    leftPaddle.setOrigin(paddleSize / 2.f);

And give me these erors:

F:\CPlusPlus\Work\AnticPong\anticpong.cpp||In function 'int main()':|
F:\CPlusPlus\Work\AnticPong\anticpong.cpp|50|error: no matching function for call to 'sf::RectangleShape::setTexture(sf::Texture&)'|

The documentation shows you the correct function signature of sf::RectangleShape::setTexture(). Or even your error message, if you read it exactly.

I can't understand how to put it correctly.

Have you even tried? The documentation states that the function has this signature:

void setTexture(const Texture* texture, bool resetRect=false)

As you see, it takes a pointer. You however are passing a reference.

[AlexxanderX]

Yes, I read it, but I have problems in understood it and putting it in my code.

Then you should read a C++ book to learn more about pointers and references. These are very important topics, and although I can give you the solution for this specific problem, it is important that you understand the concept in order to apply it to other situations.

To get a pointer to the texture, you need to take its address with the address-of operator.

Thanks. After reading some tutorials and start understand what mean pointer I succefully made it.
Here is the code, if need some modifications please tell:

sf::Texture texture;
        if (!texture.loadFromFile("resources/backgroundimage.png"))
     return -1;

     const sf::Texture *pTexture = &texture;

    // Jucatorul din stanga
    sf::RectangleShape leftPaddle;
    leftPaddle.setSize(paddleSize - sf::Vector2f(3, 3));
    leftPaddle.setOutlineThickness(3);
    leftPaddle.setOutlineColor(sf::Color::Black);
    leftPaddle.setFillColor(sf::Color(100, 100, 200));
    leftPaddle.setTexture(pTexture);
    leftPaddle.setOrigin(paddleSize / 2.f);

That's correct. You can also directly pass the address of the texture:

leftPaddle.setTexture(&texture);
