Re: [pygame] Hexagonal collision detection?

[Jasper <jasper@xxxxxxxx>]

I don't have hexagonal buttons per se, but a hexagonal map.  The effect 
is much the same, as you need to know which one has been clicked, 
although it's complicated somewhat by being viewed in 3D via pyopengl.

I draw all the hexes as quads with a hex map texture and transparent 
corners.  For each I generate a second "mouse map" texture encoding 
color (e.g. (x,y,0)) that is drawn behind the scenes when the mouse is 
clicked, and I simply check what color is under the mouse and decode the 
clicked hex location.
