Hello! i am very much new to the Roblox development scene, my past experiences are JASS (Warcraft 3) which is a language that specializes in arrays and Integer, however what I want to know is that

How does one make a table of arrays in Roblox Studio that refers to the conditions of a player?

for example, in array [1,1] we have the ID of the player, in array [2,1] we have the rank of requirement for something to happen,
what i want to accomplish is how does the LUAU logic work regarding the referral of an array's type of execute a command?

for simple terms, how does one make the code so that it checks the player ID in a table and their rank in the group for a command to be executed, right now im trying to learn arrays pretty much.

I don't think I have understood you at all but you may be talking about arrays overall. I don't know what JASS is but here in Lua if you want to check, using arrays only, you would make a dictionary in which the player data is stored

local players = {
  1736716372 = {
    ["RANK"] = "Owner"
  }
}

And then you access its rank by doing players[1736716372]["RANK"]

crisp heath I don't think I have understood you at all but you may be talking about arrays o...

would it be possible so that

#

if a player is ranked such and such it would go to a specific array-table

#

for it's ID

#

for example

#

when a player joins --> it's ID would be identified if it meets with the rank scope it is on a table

#

and if it is positive it happens

#

the scope being if it's ID is set on an array for a rank

tame beacon Hello! i am very much new to the Roblox development scene, my past experiences a...

theres no such thing as "array" in lua

#

local Table1 = {1, 2, 3, "abcd", 999} -- this is a table
print(Table1[2]) -- 2
print(Table1[4]) -- "abcd"


local Table2 = {
  a = 1,
  b = 2,
  abc = "textextext",
  another_table = {1,2,3}
} -- this is also a table
print(Table2.a) -- 1
print(Table2["b"]) -- 2


local Table3 = {
  1,
  2,
  a = 7,
  lol = "foo",
} -- this is called MIXED TABLE it is also a thing but you should really avoid doing like this
print(Table3[1]) -- 1
print(Table3.a) -- 7
print(Table3["lol"]) -- "foo"

grand jasper theres no such thing as "array" in lua

so i assume arrays in luau is tables

grand jasper Dec 21, 2023, 7:45 PM

#

yes

tame beacon Dec 21, 2023, 7:46 PM

#

i assume it still has the same concept

#

are tables in luau dynamic or static

grand jasper Dec 21, 2023, 7:46 PM

#

tables combine functionality of arrays and dicts

grand jasper Dec 21, 2023, 7:46 PM

#

tame beacon are tables in luau dynamic or static

what you mean by that

tame beacon Dec 21, 2023, 7:47 PM

#

for example, tables have a value on rows etc etc

#

can they be changed via a dynamic trigger (a script triggering)

#

or is there like a specific Dynamic table

#

that is a table but can be changed

grand jasper Dec 21, 2023, 7:47 PM

#

table has Indexes and Values
index can be a number or a string, value can be anything

tame beacon Dec 21, 2023, 7:48 PM

#

can they be changed mid-way before initialization?

studio ** You are now Level 1! ** studio

grand jasper Dec 21, 2023, 7:48 PM

#

Table[Index] = Value

tame beacon Dec 21, 2023, 7:48 PM

#

is pretty much my question

tame beacon Dec 21, 2023, 7:48 PM

#

grand jasper `Table[Index] = Value`

i assume i can make an index of an index aye?>

grand jasper Dec 21, 2023, 7:48 PM

#

local Table = {}

Table.a = 999

grand jasper Dec 21, 2023, 7:49 PM

#

grand jasper local Table = {} Table.a = 999

this code assigns 999 to index "a" of table Table

tame beacon Dec 21, 2023, 7:49 PM

#

does Table.1.1 means it assigns 1 of the 1st in "Table"

#

or can there only be 1 index

#

in a table

grand jasper Dec 21, 2023, 7:50 PM

#

you cant do Table.1

tame beacon Dec 21, 2023, 7:50 PM

#

#

to simplify it basically

grand jasper Dec 21, 2023, 7:50 PM

#

tame beacon

tables are not 2d

#

dont think of them as 2d

tame beacon Dec 21, 2023, 7:51 PM

#

so if that's the case i assume i can add an index of an index

#

in Roblox's Table?

#

so that i dont have to make a thousand types of tables if needed be

grand jasper Dec 21, 2023, 7:52 PM

#

local Table = {}
print(Table[1]) -- nil
Table[1][1] = "something" -- error

tame beacon Dec 21, 2023, 7:53 PM

#

and if it prints [1][1] it will give "something" as an output

#

correct?

grand jasper Dec 21, 2023, 7:53 PM

#

yes you can put a table inside of other table and then it will kinda act as if it was 2d

tame beacon Dec 21, 2023, 7:53 PM

#

sweet

grand jasper Dec 21, 2023, 7:53 PM

#

look

#

no wait look

tame beacon Dec 21, 2023, 7:53 PM

#

yep? im lookin

grand jasper Dec 21, 2023, 7:54 PM

#

if you do print(Table[1][1]) it will error because Table[1] is nil (nothing) and you basically trying yo do print(nil[1]) which gives error

#

however

#

if you do Table[1] = {} beforehand it will not error

#

idk how to explain this propperly

tame beacon Dec 21, 2023, 7:55 PM

#

oh because the scope is table 1

#

yeah i understand how scope works

#

it basically means you run something under this alias

#

seeing that we run it under table 1

#

it defines that whatever is INSIDE of table 1 that we are about to trigger will be triggered

#

which is [1] inside of [1] to be the output

#

correct?

#

seeing the original one is

#

we run whatever is in the first index of "Table"

grand jasper Dec 21, 2023, 7:56 PM

#

what are you trying to do

tame beacon Dec 21, 2023, 7:58 PM

#

grand jasper what are you trying to do

right now seeing i want to become a backend programmer im using this table to compile people's name under an index [1] being let's say organizer only for it to verify the player's id that is stored manually in the index

outer pathBOT Dec 21, 2023, 7:58 PM

#

studio ** You are now Level 2! ** studio

tame beacon Dec 21, 2023, 7:58 PM

#

it's a foolproof solution if someone tries ranking some random organizer

#

without going through the developers

#

so that organizers must be put in the data inside of the game and ranked

#

rather than just purely ranked

grand jasper Dec 21, 2023, 7:59 PM

#

why dont you use data inside the game only?

#

like why do you need group rank if you gonna check data inside the game anyway

tame beacon Dec 21, 2023, 8:00 PM

#

grand jasper like why do you need group rank if you gonna check data inside the game anyway

well one it's for show and it's something that will be linked to bloxlink so might aswell

#

so you cant really be an organizer without being in the group and the data

#

so if we add someone in the data

#

but they arent in the group (which doesnt trigger the script)

#

then they wont be given organizer ingame

#

so that people can remove their ranks on a whim

#

and people cant add people on organize

#

on a whim

#

it must be verified both ways like a blockchain

#

hence the use of arrays / tables

grand jasper Dec 21, 2023, 8:13 PM

#

ive made a possible solution but its kinda not easy-to-understand

#

idk

tame beacon Dec 21, 2023, 8:13 PM

#

ooh hit me with it

grand jasper Dec 21, 2023, 8:13 PM

#

local GroupId = 0000 -- your group id

local GroupRanks = {
  Owner = 255
  -- Rank Name = Rank id in group
}

local UserRanks = {
  Owner = {
    999999999,
    -- Userids of users in this rank
  }
}

function GetRank(Player)
  for Rank, UserIds in next, UserRanks do
    if table.find(UserIds, Player.UserId) then
      local GroupRank = GroupRanks[Rank] or 0
      return Player:GetRankInGroup(GroupId) >= GroupRank and Rank
    end
  end
end

#

idk

#

maybe its easy for u maybe not

#

so

tame beacon Dec 21, 2023, 8:13 PM

#

this is actually

#

mind boggling

#

so i dont have to use tables

#

holy cow

grand jasper Dec 21, 2023, 8:14 PM

#

GroupRanks contains association between group rank ids to rank names

#

255 is group owner

tame beacon Dec 21, 2023, 8:14 PM

#

i assume the Player in GetRank(Player) refers to every individual player

grand jasper Dec 21, 2023, 8:15 PM

#

when you call GetRank(Player) it returns rank name or nil

tame beacon Dec 21, 2023, 8:15 PM

#

the rank name of the player or the rank name of?

grand jasper Dec 21, 2023, 8:18 PM

#

game.Players.PlayerAdded:Connect(function(NewPlayer)
  local Rank = GetRank(NewPlayer)
  print(`Player {NewPlayer.Name} with rank {Rank} has joined!`)
end)

tame beacon Dec 21, 2023, 8:18 PM

#

ah this is what i was wondering for

grand jasper Dec 21, 2023, 8:18 PM

#

grand jasper ```lua local GroupId = 0000 -- your group id local GroupRanks = { Owner = 255...

also I didnt test this

#

so there may be mitakes

#

idk

tame beacon Dec 21, 2023, 8:19 PM

#

oh yeah no dont worry man :D
im here to ask on what the stuff is

#

so far i have a great gist on what you are saying right now which is good seeing to be fair

#

i think it's stupid for me to ask here for someone to make me a whole script and just copy paste it in studio :]

#

so right now thanks to you i actually know about tables in luau

tame beacon Dec 21, 2023, 8:20 PM

#

grand jasper ```lua local GroupId = 0000 -- your group id local GroupRanks = { Owner = 255...

however for this case, what if there is more than 1 rank

#

is GroupRanks it's own variable / string?

#

because i see local behind it

grand jasper Dec 21, 2023, 8:26 PM

#

for example you want to add new rank called "Head Admin"
in your group corresponding rank has id = 254
and you want 3 players with userids of 111111, 222222 and 33333 to have it

in GroupRanks you specify required group rank id:

local GroupRanks = {
  Owner = 255,
  ["Head Admin"] = 254
}

you add the users to UserRanks:

local UserRanks = {
  Owner = {
    999999999
  },
  ["Head Admin"] = {
    111111,
    222222,
    33333
  }
}

done! that should work. now GetRank will return "Head Admin" if one of those 3 players join and if he have 254 or higher group rank

#

if player has group rank but not on the UserRanks table -> GetRank will return nil
if player is in the UserRanks table but does not have group rank -> GetRank will return nil

tame beacon Dec 21, 2023, 8:27 PM

#

why does the head admin ahve brackets

#

and not owner

#

cant they all have brackets

grand jasper Dec 21, 2023, 8:28 PM

#

beacuse there is a space

#

you cant do Head Admin = "something"

tame beacon Dec 21, 2023, 8:28 PM

#

AH because there's more than 1 inside of Head Admin

#

then what about

local GroupRanks = {
Owner = 255,
["Head Admin"] = 254
}

grand jasper Dec 21, 2023, 8:29 PM

#

tame beacon then what about local GroupRanks = { Owner = 255, ["Head Admin"] = 254 }

?

#

you sent the same table

tame beacon Dec 21, 2023, 8:29 PM

#

oh it's the same table i thought it's different because its GroupRanks

#

not UserRanks

#

i was copying that table because if i look at that one which is GroupRanks

#

it has no value other than the id

#

so cant i do Head Admin = 223

grand jasper Dec 21, 2023, 8:30 PM

#

local GroupRanks = {
  ["Owner"] = 255, -- this will also work
  ["Head Admin"] = 254
}

tame beacon Dec 21, 2023, 8:30 PM

#

oo

grand jasper Dec 21, 2023, 8:31 PM

#

tame beacon so cant i do Head Admin = 223

?

tame beacon Dec 21, 2023, 8:31 PM

#

grand jasper ?

as in

outer pathBOT Dec 21, 2023, 8:31 PM

#

studio ** You are now Level 3! ** studio

grand jasper Dec 21, 2023, 8:31 PM

#

same table cant have 2 identical indexes (keys)

tame beacon Dec 21, 2023, 8:31 PM

#

local GroupRanks = {
Owner = 255,
Head Admin = 254
}

grand jasper Dec 21, 2023, 8:31 PM

#

tame beacon local GroupRanks = { Owner = 255, Head Admin = 254 }

no

#

you cant

#

if the key contains spaces then you should enclose in [""]

tame beacon Dec 21, 2023, 8:33 PM

#

ah i see

#

well seeing i can use brackets on all

#

it would look clean

#

Thanks man! @grand jasper appriciate it man

grand jasper Dec 21, 2023, 8:34 PM

#

youre welcome, I hope my code helps
