~-Replace this Thread when it's supposed to be somewhere else-~

Welcome to my second tutorial/guide wich is about Tables.

~-Indexing-~
Tables are good for storing data, you create a Table by using the '{}' symbols:

Code:

local tab = {}

Indexing a table is easy and can be done in around four ways:

Code:

local tab = {k = "Hello World"}

or

Code:

local tab = {}
table.insert(tab, k = "Hello World")

or

Code:

local tab = {}
table.insert(tab, k = "Hello World", 1)

Now example1 will create a table with k = "Hello World", so if I say print(k) it will result in "Hello World".

Example2 creates an empty Table and indexes it with k = "Hello World" so afther that the Table looks like example1.

Example3 creates an empty Table too, but the given value is indexed on key 1.

~WARNING: Don't call a Table 'table' or 'Table' also don't frogot that table.insert(table, value, key) might replace the key that's aleardy been setted:
local tab = {j = "Hello World"}
print(j) --> Hello World
table.insert(tab, j = "Oh my", 1)
print(j) --> Oh my ~

~- The use of for loops in a Table -~

For loops are very usefull at Tables:

Code:

local names = {}
script.Parent.Touched:connect(function(p)
local h = p.Parent:findFirstChild("Humanoid")
if h then
for _,v in pairs (names) do
if h.Parent.Name == v then
print("Aleardy touched")
elseif h.Parent.Name ~= v then
table.insert(names, h.Parent.Name)
end
end
end
end)

So that creates a Table called "names".
Line 2, 3 and 4 are obvious.
Line 5: A for loop is created with v == all values in the Table "names"
Line 6: Checks if h.Parent's Name is equal to all the values in the Table names.
Line 7: If the if statement returns true then it prints "Aleardy touched".
Line 8: Else h.Parent's Name ISN'T equal to all the values stored in the Table "names" then
Line 9: If the elseif statement returns true then it inserts h.Parent's Name into the Table "names"
Line 10-13 are all the ends.

There are many Table functions, such ash table.insert, table.insert, table.concat etc read more about these functions in the Wiki:

Someone rate please?

Pretty good.

i think you should put more philosophical information in this

I think you should put more correct information in this :/

Better way to say it ;)

i think correct and philosophical are different

maybe so. Close enough to be the same.

Altough I wanted to make a quick tutorial.

uggg im very confused, can someone explain this to me i might have missed something or im just a noob idk can someone tell me what that script would do ^ -_-

isn't it table.insert(tab,k,"Hello World")???

No, cuz k isn't a number value and I want k being defined to "Hello World".

Bluey, did you lose your admin powers?

yup , and I got them back!

test this:
print(table.insert({},"k","Hello World!")["k"])

it should print 'Hello World!" in the output. correct me if I'm wrong
