[Question/Feature request] Pathfinding on a hex grid

[JohnTheCoolingFan]

Is it possible to use this lib for pathfinding on a hexagonal grid? If not, it t would be awesome if support for this is added.

[Samuel Tardieu]

Pathfinding algorithms in this library are not tied to any state representation. You can look at the sliding-puzzle example which is an example of a sliding puzzle (as the name indicates) and doesn't use any grid.

So yes, as long as you can figure out how to represent your various tiles and which tiles are neighbours of others, it will be perfectly suitable.
