I advocate polar coordinate based systems for hex maps, but you still have to convert to Cartesian maps for rendering which I consider a nuisance.

The core concepts are that you declare an Origin Hex (0) and everything you perceive from there is simply a series of concatenated single-hex vectors (1A, 1B, 1C, 1D, 1E, 1F) from the origin (0 + 1A + 1B + 1C = 2B)

Functions include:
Simplify – takes a concatenated vector and renders a 2 vector result to uniquely identify the target
Combine (A+C = B)
Negate (A+D = 0)

Doing these from Memory:
ABBCCCDDDDEEEEEFFFFFF = 1A2B3C4D5E6F
1A2B3C4D5E6F = (1,2,3,4,5,6)
some other format conversions
some true path conversion

I had started to create some JavaScript ports and I’m pretty sure those are still floating around close by.

What all this buys you is a native way to represent the data for AI and other traversal logic and you just need to apply some Trig and other Flash magic to render the hexes.

Same here, I’d love to be able to look at your source code?

Thank you very much!

I do not see any code but comments. Could you repost it here or email it to me?

Thank you in advance,
Pavel.

I have been looking for such a library in javascript for use with the new Canvas 2D. I don’t see the source code in the text box, only the comments. Could you please send the source code to:
kmandrup@gmail.com

Then I would love to build on that. I already made some code myself to draw a tiled hexagonal map, but need code to determine hexagon clicked, movement etc.

I found some old articles on the web too… but this looks great!
Good luck!
