Hello everyone! 🙂

I’ve been wondering if anyone can point out a way to make a circular hex grid.

The idea is simple: I need to call a method of every tile in a radius around some certain tile.

Basically I need to calculate their X and Y position around that tile.  
One more problem - the values of X and Y will be different depending if the tiles Y is even or odd.
