Hi,
in the recent few days I have started to implement a small library with example codes for hex tile based maps.
This is a JavaFX 8 implementation of the algorithms and the cube logic from Amit Patels “Hex Grids Implementation” site. I made few additions and added code for processing of Tiled TMX-files from Kevin Kelley and his project “simpletmx” (https://code.google.com/p/simpletmx/) and search algorithms from zeroturnaround and his project “jf-hw-performance” (https://github.com/zeroturnaround/jf-hw-performance).
If you like have a look and give me feedback here. The URL is on github: https://github.com/rfrerich/hex4j
In the subfolder src/main/java/de/lambdamoo/hex4j/test/ is a showcase with rendering a hex-map on a JavaFX canvas.
Regards René
