Added two function
index_to_cubecoord : index to Cube coordinates (pointy) conversion based only on its input (int index) and CubeCoord.directions
cubecoord_to_index : Cube coordinates (pointy) to index conversion based only on its input (int x, int y, int z)
tested and verified
for (int i=0; i<37; i++){ CubeCoord c = index_to_cubecoord(i); int j = cubecoord_to_index(c.x, c.y, c.z); System.out.println(String.format("%d -> (%d,%d,%d) -> %d", i, c.x, c.y, c.z, j)); assert i == j; }
