problems with copying renderTextures

[soaup]

Hello and sorry for bad english! I had tried implement multiple shaders as described herein, but use RenderTexture. And it is not copied.

how i tried:

foreach (sf::Shader *shader, globalShaders) {
        front.clear();
        sf::Sprite sprite(back.getTexture());
        front.draw(sprite, shader);
        front.display();

        sf::RenderTexture temp = front;
        front = back;
        back = temp;
    }

And this error

C:\SFML\include\SFML\System\NonCopyable.hpp:67: error: 'sf::NonCopyable::NonCopyable(const sf::NonCopyable&)' is private
     NonCopyable(const NonCopyable&);
     ^

the problem disappears if you comment out the line

//sf::RenderTexture temp = front;
        //front = back;
        //back = temp;

Please answer - what is the problem?

sf::RenderTexture temp = front;
front = back;
back = temp;

You are in fact trying to copy the RenderTexture around.
The other thread uses pointers(which can be copied) to do what you want.

Not trying to be rude here, but you should get a fundamental knowledge about C++ first.

Yes, i did it with pointers and it works. I forgot pointers.
