Bug : filtering vertices.
« on: March 31, 2014, 11:42:26 am »
Hi, I've made a class to filter all vertices by material and primitive type to put them in a vbo.

I put them in a std::map but when I try to insert them into the std::map I get this error :

If I redefine the operator< I get a crash.

std::map needs an operator < to sort its keys. Or, if operator < for the key class is not relevant, you can pass a custom functor as an extra template argument to std::map.

I'm scared by all these warnings in your code. They are pretty serious, you should fix them first.

Mmm..., ok, I think I'll make a std::vector of std::pair..., I really don't need to sort something here, I don't see how can I sort primitive types.

And I'll correct those warnings.

Feel free to correct me Laurent, but shouldn't we try to keep focusing on SFML related issues/topics here?
I've nothing against a few general C++ problems and most of them were often connected to SFML is some way in the past, but once you sail your own ship independently from SFML, shouldn't one be looking for a more general forum/community (e.g. StackOverflow) for general programming issues? ;)

I think, it's okay to keep updating project pages even if they don't depend on SFML anymore, but for specific issues, StackOverflow seems not only better for us, but also better for the poster, given that there are many very experienced programmers.
