Re: Simple Terrain Calculator...
For those that prefer Perl, here's my similar function (from my perl dom library project).
The function return an array with the list of all types.
Quote:
# extract list of terrain types from the numeric code
sub get_terrain_types_from_code($); # function prototype, prevent warning when the function try to call itself recursively in strict mode
sub get_terrain_types_from_code($)
{
my $terrain_code = shift;
if ($terrain_code !~ /^[0-9]+$/)
{
error("[get_terrain_types_from_code] terrain code must be numeric value ('$terrain_code')");
}
my @terrain_types = ();
# terrain code is the sum of the successives individual terrain type code values
if ($terrain_code >= 4194304) # "edgemount" 4194304
{
# code >= 4194304 means that province type include "edgemount"
push (@terrain_types, "edgemount");
# now get the other types (if any) by recursive call
push (@terrain_types, get_terrain_types_from_code($terrain_code - 4194304));
}
elsif ($terrain_code >= 2097152) # "priestsite" 2097152
