Strange error when passing a reference to sf::RenderTarget

[pabloist]

I'm not really sure why I'm getting this error, since I've done this before in other programs. It happens when I attempt to call sf::RenderTarget.Draw(sf::Sprite) - it tells me that I'm attempting to call a pure virtual method.

Code: [Select]

void Draw(sf::RenderTarget& target)
{ target.Draw(sprite_); }

and then in a drawing loop, I'd have

Code: [Select]

// Window declaration
sf::RenderWindow App(/* construction */);

// Drawing loop
for (/* all objects */)
{ iter->Draw(App); }

Is there something wrong with what I'm doing? Or should I try posting more code? Will I be forced to use pointers to make sure the polymorphism kicks in? It's weird, since this has worked before...

No, you don't need pointers since you use references.

Is the posted code the original one? What's the declaration of your container that iter is refering to? Seems like you're somewhat calling sf::Drawable::Draw() (indirectly) which calls sf::Drawable::Render(), and that's pure virtual.

I guess more (original?) code would be useful. Or even a minimal example to reproduce the problem.

EDIT: Nevermind! I realized that the objects that I was attempting to call Draw() from (that were stored in a container) were destructed before I managed to draw them. [/b]
