Hashtags in front of variables?
Hey, I'm new to Lua but not to programming and just have a quick question. I've seen a few scripts in which there is a hashtag in front of a variable, for example...
if #players > 0 then local randomplayer = players[math.random(1,#players)]
This is part of a script that selects out a random player, is this statement returning that #players is an integer. Or is it creating an array or something?
Thanks in advance.

The # operator returns the amount of items in a particular table. That's why #[table] (in this case, #players)is an integer.
Some examples:
Table1 = {"HI", "ok", "item"}
Table2 = {324, 523, 64, 2345}
print(#Table1)
print(#Table2)
In the output, you'll get:
3
4
So in your script, it's basically saying:
if #players > 0 then
If the number of players is greater than 0, then...
local randomplayer = players[math.random(1,#players)]
The randomplayer will be a random player between the first index and the last index of the players table.
players would actually be a table. A hashtag before a string or table returns the length of that string or table. For example:
local tab = {"one",2,"3"}
local string = "I'm a string!"
print(#tab) ---------------> 3
print(#string) ---------------> 13
print(#"apple") ---------------> 5
