How to convert table to string?
Hello, I have a little code which is for my game. Take a look at the script:
players = game.Players:GetPlayers()
if table.getn(players) >= 4 then
crim = players[math.random(1, #game.Players:GetPlayers())]
table.remove(players, players[crim.Name])
plrs = tostring(players)
print(plrs)
print(players)
...
This is in a while true do loop. So I am selecting one player as a criminal, and then removing it from the 'players' table, to make everyone else a police. But when I try to convert the table to a string (to test if it worked), it gives me 'table:' and random characters, such as 13E2F21, both times: print(plrs) and print(players).
My question is, how to convert a table to a string? Sorry for my bad English EDIT: I have tried to comment table.remove(......) with --, but it still not converted the table to string

It's not random; it's the memory address of the table! If you want to print all the elements of the array, use unpack() since it returns all the elements of a array.
Additionally, you should use the length operator # to get the table length.
players = game.Players:GetPlayers()
if #players >= 4 then
local num = math.random(1, #players)
local crim = players[num]
table.remove(players, num) -- # remove takes the index to remove not value
print(unpack(players)) -- # print all the elements
print(players)
end
It would also be prudent to mention table.concat but this only works for string and number elements, and instances are not strings or numbers, so this will fail.
local arr = {"one", "two", "three"}
print(table.concat(arr, ", ")) --> one, two, three
However this is out of the scope of this answer so I will not explain any further.
