I'm trying to get the length of an array in Lua with table.getn. I receive this error:
The function table.getn is deprecated!
(In Transformice Lua)
Use #:
> a = {10, 11, 12, 13}
> print(#a)
4
Notice however that the length operator # does not work with tables that are not arrays, it only counts the number of elements in the array part (with indices 1, 2, 3 etc.).
This won't work:
> a = {1, 2, [5] = 7, key = '1234321', 15}
> print(#a)
3
Here only (1, 2 and 15) are in the array part.
