INTRODUCTION [1.1]
this is a library for using hexagonal grids in amulet/lua. it is extremely incomplete. the following list of features is either implemented shoddily, or not at all.
if you want an actual good resource, go to [1.9].
GETTING STARTED [1.2]
//TODO
COORDINATE SYSTEMS [1.3]
as much coordinate manipulation as possible is done internally. depending on the task, uses either Axial, Cube, or Doubled coordinates.
three different ways of returning and sending coordinates:
- amulet vectors
- lua tables
- individual coordinate numbers
so you can use what your graphics library likes best!
MAPS & MAP STORAGE [1.4]
Some map shapes: parallelogram, rectangular, hexagonal, triangular. (and more)
- storage system based on map shape - see chart:
SHAPE | MAP STORAGE |
---|---|
parallelogram | unordered, hash-like OR ordered, array-like |
rectangular | unordered, hash-like OR ordered, array-like |
hexagonal | unordered, hash-like OR ordered, array-like |
triangular | unordered, hash-like OR ordered, array-like |
ring | ordered, array-like |
spiral | ordered, array-like** |
arbitrary | unordered, hash-like |
** note that a spiral map is just a hexagonal one with a particular order.
CONVENTIONS AND TERMINOLOGY [1.8]
because so many different kinds of coordinate pairs, trios
