/* The code is copied from Ragundo's repo referenced below.
|
||||
The changes are:
|
||||
- The addition of a .h file reference.
|
||||
- The simplification of the code using ofsub to remove the use of (and
|
||||
.h reference to) that function (analysis of the code showed the
|
||||
simplified code is the result, as the ofsub expressions will never be
|
||||
true given the range of the values it can be passed in these functions).
|
||||
- The change of the main function to take a separate y coordinate for
|
||||
use in the tropicality determination to allow proper determination of
|
||||
the tropicality of mid level tiles ("region tiles") referencing a
|
||||
neighboring world tile's biome.
