Errors with using functions and print?
So, when I was messing around with studio, I decided to make a small game. I made a script to return the Players in the "Players" menu in the Explorer.
I used print to check if the script was working, however, when I ran the game, an error popped up in the output that said " Workspace.Script:3: function arguments expected near 'print' ".
In case you were wondering, this was the test script I used:
local returnedPlayers = game.Players:GetPlayers print(returnedPlayers) -- printed the table
Then I tried to use functions to fix the issue:
local returnedPlayers = game.Players:GetPlayers
function testPrint() -- the function
print(returnedPlayers) -- printed the table
end
testPrint() -- calls the function
But the error still persisted. (The only difference was "print" was changed into "function".) However, when I first used studio, it worked fine. Can someone explain what changed or what I am doing wrong?

You forgot the brackets on GetPlayers. It should be :GetPlayers(). However, since GetPlayers returns a table and you try printing a table, it will return its ID, not its contents.
To get the contents (specifically, print them), use a for loop.
local PlayersTable = game:GetService("Players"):GetPlayers()
for i, v in pairs(PlayersTable) do -- Generic for loop
print("Index:", i, "Value:", v)
end
-- You could also use a numeric for loop
for i = 1, #PlayersTable do
print(PlayersTable[i])
end
Since this is a table, I would recommend using a for loop. This should work ~~~~~~~~~~~~~~~~~
local returnedPlayers = game.Players:GetPlayers() for _,i in pairs(returnedPlayers) do print(i.Name) end
~~~~~~~~~~~~~~~~~
