As far as I am aware
_G.table = {""}
This creates a global table that I can access to store and delete data to/from?
Is that correct?
If so, how can I rename the table, and how can I put things in it and delete everything in it from another script?
Thanks
jj

_G.Thing = {};
_G.Thing.A = "Lel";
local n = _G.Thing;
_G.Thing = nil;
_G.Otherthing = n;
n = nil;
print(_G.Otherthing.A)

Thx - so does that script create a global table and put something in called lel, and another table called thing and another called overthing? Would those work in another script?

That makes a table in the _G table called thing, and then it renames thing to Otherthing very inefficiently

Ah ok! Thanks - so very simply, I could create a global table, and put something in it from another script and delete it from another script? But how?

The same way as any other table.

Ah ok! Cool! Thanks!
Just one last question...
I create a table called like this like this - _G.Escapers = { }
From another script, do I have to "call" it with the _G.?
Or can I just put stuff in it using the Escapers = { }?

You have to use the _G

Because Roblox.

Oh - another quick question xD

_G.Thing.A = "Lel";


Why did you put the ".A" ??

Why do you have to put ".A" though? What does that do?

Stops you from overwriting the table -.-

It didn't have to be A
It just was.

Tables can be accessed three ways:

1. tableVariable.key
2. tableVariable["key"]
3. rawget(table, "key")

Note that with methods 2 and 3 you can use integers or even variables as indexes. _G is a variable holding a table. It works just like any other variable that holds a table.

OK thanks!
So now, In a script I have _G.Escapers = {} which creates the global table and in another script I have

script.Parent.Touched:connect(function(hit)--when the brick is touched
print ("Player touched!")
for key, value in next, _G.Escapers do
if value == hit.Parent.Name then
return
end
end
table.insert(_G.Escapers, hit.Parent.Name)
end);
game.Workspace.Time.Changed:connect(function(newValue)
if newValue == 0 then --if the time is equal to 1 then
hdd= game.Workspace.Announcer
end
if _G.Escapers == 0 then
hdd.Text = "Nobody Escaped."
else
hdd.Text = "The players that Escaped are: "..table.concat(+G.Escapers, ", "); --display the winners in a message
wait(3)
hdd.Text = ""
for key, value in next, _G.Escapers do
local c = game.Players[value].leaderstats.Coins
c.Value = c.Value + 10;
end
end
end);


All look right?
Thanks!

Don't get confused.

Clients get their own global table. So, for example, if you tried adding something to a server global table from a client's table, it would add to the client's table. Not to to the server.


To make things clear, any script in each player's PlayerGui, Backpack, etc, it accesses their own personal global table.

OK, thanks.
Both these scripts are in the workspace, so would the second work by adding the names of players that touch the brick to the global table?

Yup it will work.

"Did you order biscuits from the bakery?" - What?? :D

OK, thanks! The reason I am using a global table is that I have more than one brick with that script in - they all need somewhere to add the players names to!!

In that case you should use one master script.

1. tableVariable.key

I should learn what those are lol

@Cry - I can't just use one script as I need to create the global table and then in other scripts, check if they touch the brick and if they do, add them to the global table. Is there more of an efficient way to do that, then? :D

My son, there is always a more efficient way to do something.

I suggest pulling all the code in one script using RemoteFunctions if you need to do something to the client. Of course there is always in pairs loops.
