Wow, Laurent here...

So, to summarize. My (and that guy's too) idea was to create std::vector of pointers to sf::Drawables. Idea was pretty nice, and everything was OK, until I went into deleting pointers. I created a typical loop using iterators, like this:

for(auto a = vector.begin(); a != vector.end();)
{
    if(**a == this->sprite)
    {
          //remove
     }
     else
     { ++i; }
}
 

The problem is, I cannot compare dereferenced iterator to our sprite. Visual Studio even gives weird error about sf::Sprite != sf::Sprite. And that's pretty much the case.

I thought about using some ID, but I don;t know if it is something good.

General / [SOLVED] sf::Drawable managment

Hi there!

I'm doing SFML for a while, but I have a question. How to manage sf:Drawables in a game? I'll expand that:
I want to have something like that: I have a special object that stores all sf::Drawables in container, that object also has inherited draw(). All of this is to simply write one function to draw all the drawables. But i went to a problem well described here: https://en.sfml-dev.org/forums/index.php?topic=14262.0. So, I'm thinking, how to do that. I would have system that registers any drawables automatically, in object constructor. Somebody suggested using std::map and ID's, but it is possible to just use Vector?
