How do you index the last element in a list??
Here's my attempt based on how its done in Python or Ruby
01 | local list = {1,2,3,4} |
02 |
03 | print(list[-1]) |
04 |
05 | >> 4 |
06 | ---------- |
07 |
08 | local list = {A, C, D, R, G} |
09 |
10 | print(list[-1]) |
11 |
12 | >> G |
list[-1] returns nil, is there an end of list reference in LUA might of just missed it but can't seem to find it in the docs, roblox or lua
*I can table.getn(list) and use that but I was just curious if there was something like the example above?

In the list, you are placing a letter alone which is considered nil. To make something a string, you would place quotations around it like this; "A". Therefore If I were to print "A" it would print A rather than nil. In your list/Array you should be doing {"A","C","D","R","G"} . If you try printing now, It should print the letter G itself.

Well in lua, to get the last member of a table/ last element in a list, you would use the length operator, or #, which is the easiest way of achieving this. This is the case as arrays in lua start at 1 instead of 0, unlike most other languages.
Also note that the getn function was deprecated in 5.1
Length operator
1 | local tbl = {41,"owo",412,14,25,24,254,23} |
2 |
3 | print(#tbl)--8 |
4 |
5 | print(tbl[#tbl]) --23 |
6 | print(tbl[8])--23 |
Hopefully this helped! And be sure to accept this answer if it did
