Title: Problem using an STL vector of sf::Vector2f s
Post by: bendy on January 01, 2015, 08:50:36 pm

Hi,
I am trying to load up an STL vector with sf::Vector2f s.

The problem is when I try to use an iterator over the vector. The iterator keeps on going past the stop condition.

                 std::vector<sf::Vector2f> points;
                 std::vector<sf::Vector2f>::iterator pIter;

                 for(pIter = points.begin(); pIter !=points.end(); pIter++) {
                 }   

And the real funny part is that sometimes it works and sometimes it doesn't.

Any suggestions?

Based on just what you posted I'd say that something must be up with your tool-chain; but that's really just guessing.
The code snippet looks sane enough (old-school but sane).
Does the same thing happen if you use modern C++ - like:

for (auto& point : points) { ... }

?
Could you provide a comple, minimal, compilable example so other people can try to replicate your results?
Also, more details on OS and tool-chain would be good.

It works perfectly. I had made an error in my algorithm elsewhere which was producing the mayhem.
Thanks everyone.
