Hexagonal Grids, how do you find which hexagon a point is in?

Question

I have a map made up of rows and columns of hexagons

This isn\'t an actual image of the hex-map I am using,

Answer 1

I found a different way to see if the mouse is in a hexagon. Using a bit of trig you can find the angle of the line between the mouse and the centre of the hexagon, using this angle you can work out how long the line would be from the centre of the hexagon to the edge of the hexagon at that angle. Then just check the length of the line between the mouse is less than the expected length to the edge of the hexagon. If anyone wants an example code i can share.
