how to reference a table using the colon syntax

[subtle galleon]

local t: table --table isnt a thing??

[tame matrix]

I could not find it either ig you can do smn like this (Not sure if this is good)

type tbl = {}
local testTable: tbl = {
  -- Table ig?
}; 

[subtle galleon]

yeah i mean i could just do :{} but i gotta insert inside it the stuff i want while i just want the argument to be a table, like, it can also be an empty table

[lethal apex]

like ```lua
type table = {any?}

[subtle galleon]

still no, in the function, when i try getting something from that table i get a warn saying the item doesnt exist

also could u explain the "?"

[lethal apex]

that checks if it is nil

not sure if that is already included in any tho

[subtle galleon]

ok

https://luau-lang.org/syntax#type-annotations
im currently reading this but i think im either dumb or theres nothing abt "free" tables

[lethal apex]

what do you mean "free" tables? empty tables?

[subtle galleon]

yeah

like anything that is a table

no matter whats inside it

cuz i dont wanna type everything i need

[lethal apex]

type tableType = {any?}
local t : tableType = {121, 123, a = 2, "asd", c = 123} --these are just examples
local t2 : tableType = {}
``` this worked for me?

unless you are talking about something else

[forest willow]

not sure, but heres the table type:

--defining
type table = {maxn: (t: table) -> number, find: (t: table, value: any, init: number?) -> number?, foreach: (t: table, f: (any, any) -> ()) -> (), foreachi: (t: table, f: (number, any) -> ()) -> (), getn: (t: table) -> number, concat: (t: table, sep: string?, i: number?, j: number?) -> string, insert: ((t: table, value: any) -> ()) & ((t: table, pos: number, value: any) -> ()), move: (a1: table, f: number, e: number, t: number, a2: table?) -> (), pack: (...any) -> {n: number, [number]: any}, remove: (t: table, pos: number?) -> any?, sort: (t: table, comp: ((any, any) -> boolean)?) -> (), unpack: (t: table, i: number?, j: number?) -> ...any, clear: (t: table) -> (), clone: (t: table) -> table, create: (count: number, value: any?) -> table, freeze: (t: table) -> table, isfrozen: (t: table) -> boolean}

u didnt write that right

[forest willow]

no

roblox-lsp gave it to me

[subtle galleon]

ok nice

[lethal apex]

can I see your current table? not sure why it doesn't work

[forest willow]

roblox doesnt consider "table" a type idk why

i had that issue before

but you can use
{any}

or, if you want to be more specific you can do:

type Something = {
  [number]: any
}

[subtle galleon]

i already tried using that, but when i try getting an item from given table it warns me that the items doenst exist in the table

[forest willow]

before you specified that the type is any

and didnt specify any element

[subtle galleon]

like
function something(param: {any})
print(param.item) --warns me
end

[forest willow]

for instance, roblox does this automatic for you

local y: {any} --[[empty table, can contain value with any type]] = {
  x = 3
}

-- roblox basically does this:
local y: {x: number} = { x = 3 }

[forest willow]

are you using strict?

here the same error

you can fix it by doing

@subtle galleon

[subtle galleon]

yeah ik that but isnt there a way to not having to reference all the keys i need in the table

[forest willow]

yes

dont use strict or type

[subtle galleon]

whats stricy

[forest willow]

and let luau do it for you

[subtle galleon]

strict

[forest willow]

--!strict

this

[subtle galleon]

im not using it

[forest willow]

are you on vscode?

[subtle galleon]

no

[forest willow]

it should not warn

[subtle galleon]

wth

[forest willow]

look at the first line of your script

if it has a --!strict

you can remove it

[subtle galleon]

trust me

theres no strict

[forest willow]

then just remove the type

[subtle galleon]

i didnt make it

theres no type

i just did as u did in the screenshot

[forest willow]

hm

did you try using table?

[subtle galleon]

yeah its not a thing

(idk why)

[forest willow]

weird...

[forest willow]

can you show me a screenshot of the warn

?

[subtle galleon]

yeah

how am i gonna do it..

if i stop hovering on it

it goes away

[lethal apex]

just write it out

[forest willow]

windows + shift + s

[subtle galleon]

🙏

[forest willow]

show me the function parameter

[forest willow]

it has a type

[subtle galleon]

what

[forest willow]

remove the {any}

and it stops the warn

[subtle galleon]

..

i would have not made this thread

if i were just gonna remove it

like i want to use it

but ig i will not

[forest willow]

hm

there must be a --!strict somewhere

it shouldnt warn you by doing this

[subtle galleon]

i swear

theres no strict

no weird stuff

just vanilla roblox studio

[forest willow]

try pressing
ctrl + f and search for --!strict

[subtle galleon]

im telling u

yk what fuck this

thanks for the help anyways

[forest willow]

np

gl

[subtle galleon]

thanks

[subtle galleon]

ok i fucking did it it was really simple

type dictionary = {[any]: any}

[tame matrix]

Oh yeah forgot about that

You could also do ```lua
type Array<T> = {[number]: T}

local TestArray: Array<number> = {
1,2,3,4,56,6,7,8,67,745,6,34,53
};

table.foreach(TestArray, print)

If you want to be fancy >:)

[subtle galleon]

nah im good

[tame matrix]

yeah

I would not do that either lmfao

[subtle galleon]

i have another question, if a paramater of a function has to be a model(or just any instance) and i want to get another instance from inside it, i get a warn saying the instance is not a key of that class, example:

function halflife(thing: Model)
  thing.Humanoid.Health /= 2 --Key 'Humanoid' not found in class 'Model'
end

is there a way to fix this

[tame matrix]

I would also like to know

[subtle galleon]

also fun fact when u reference what a function returns but it doesnt return anything in the function block it warns, even using the "?" operator after the type :

function check(x, y): boolean? --even using "?" it warns
  if x == y then
    return true
  else
    return false
  end
end --theres a little warn here cuz nothing is actually returned inside the function block but only inside the if block

u can easily fix this by just adding an empty return at the end of the function:

function check(x, y): boolean?
  if x == y then
    return true
  else
    return false
  end

  return
end --doesnt warn anymore

[subtle galleon]

can someone explain <> or send me a link to an explanation

[lethal apex]

it allows arguments to be sent thru

like
type hashtable <ARG> = {[ARG] : boolean}

[subtle galleon]

ok i understand could u provide an example tho

[lethal apex]

that was the example?

local Players : hashtable <Player> = {plr1 = true, …}

thats what it looks like used
