Is there any way to make a variable not change its value for anything in the world?

[Develo_Lua (Aawita)]

Hi! I am currently working on a project but I want to create a variable that will not change its original value for anything in the world. Is there any way to do this?

[vrs2210]

Please be a bit more specific, since I have no idea what you mean by “that will not change it’s origin value from anything in the world”

[Develo_Lua (Aawita)]

I’m trying to say that how can I make it so that a variable never changes its value for anything in the world?

[Strange_NTeeTee (Bakitkabaganyan)]

He probably means the roblox server.

[WhatDid_HeDo]

What do you mean by “anything in the world” you mean all servers or…?

[Develo_Lua (Aawita)]

nononono I am trying to say that I want a variable to never change its value for anything in the world, like for example JavaScript “constants”.

[Pure_Bacn]

If you dont change it it will never change…

[Develo_Lua (Aawita)]

is not what I am trying to say. I guess I’m not being more specific :’(

[S0MBRX]

u can achieve this by never setting anything to change that variable (:

[S0MBRX]

and do you perhaps mean it will never change data type??? because if so no the variables are polymorphic as in it will change to whatever datatype u assign it

--notice how when you run this you dont get errors
local LOL = {}
LOL = 2
LOL = "3"

[Pure_Bacn]

Using a quick google search on constants in javascript, I think he means an immutable variable (like one that you cannot change the value of).

Edit: but then again if you dont try to change the value it will never change.

Exactly, isn’t it unnecessary to make it unchangeable if you wont change it. No one else can change it anyway.

Constants in lua?

Does the Lua VM support constants? I ask this as i’d rather have the clients code break than having to do this if constant ~= value then error() stateCode = false end Like is it something simple like in C with #define constant 69420;

[Develo_Lua (Aawita)]

I want this same variable to have it with a fixed value and only fixed, but it is inside a Module and the Exploiters could change its value and that is why I am looking for an “immutable” variable.

[WhatDid_HeDo]

@RoyalTHEUSERNAME

as @RoBoPoJu said, the changes an exploiter makes to the module will not replicate anywhere else (i.e only them will view the module as being different, the other clients will not), editing a module locally and removing the function achieves effectively the same effect as nullifying the RemotEvent’s client connection in your use case, making the method redundant, if your game needs to make sure the client activates the function, you’re doing something wrong with your security

@RoBoPoJu

They can change anything visible to the client locally, but the changes won’t be visible to the server.

Unless you are checking client sided, it wont replicate.

[Develo_Lua (Aawita)]

ohhhhh I understand, thank you! I did not know that exploiters are run from the client, I thought they could be run from both sides hahaha.

[sjr04 (uep)]

Const or similar won’t prevent exploiters from modifying it. You could replicate the behavior though via a proxy table, giving it a metatable with a __newindex metamethod to throw an exception. But even then, exploiters still have the upper hand, as they can just use rawset to bypass __newindex…

[WhatDid_HeDo]

Yes, and this is why people say to never trust the client:

@IProgramForFun

never trust the client

[IFthenElse246 (Ian)]

you could just add some code that will repetitively set the variable back so it can’t be changed.
