Question

I realise this may be a duplicate, but I have searched through many forums and questions and know what causes the problem, but can’t spot it in here. I am using SFML 2.0, and I have traced the error to:

void GameObjectManager::DrawAll(sf::RenderWindow& wnd){
    std::map<sf::String,VisibleGameObject*>::const_iterator itr;
    for(itr = gameObjects.begin();itr!=gameObjects.end();itr++){
        itr->second->draw(wnd);
        itr++;
    }
}

I think this is something is not copyable, but I can’t see what it is here.

Answer 1

RenderWindow inherits from sfNonCopyable.

VisibleGamObject.draw() is probably attempting to copy wnd.
