I am getting something like:

Source can be found on GitHub. What might be the cause?

    I'd paste the code, that causes the error. A few people will follow the link and will look at your whole code, which is not short. – Kiril Kirov Nov 13 '12 at 14:34

Your problem is here

vector<int[2]> playersAtBall;

The type of the vector element must be copy-constructible. An array is not. So you can't have a vector<int[2]>. You could wrap your array into a copy constructible struct, or use std::pair<int, int> instead.

If you have C++11 compiler you can use std::array<int,2>, as mfontanini point out in the comment. If you don't, but are willing to use boost, you can use boost::array<int, 2>
