how do I get a roblox lua environment (getfenv) that will not get modified by the original environment? Here is what i tried, but non of them worked:

getfenv().lol = 'lol' -- not allowed to add code above this or remove this.


local Environments = {
	getfenv(0),

	getfenv(nil),

	getfenv(1),

	select(2, pcall(getfenv, 0))}


local DebugFuncs = {}


for i = 1, 10000 do
	pcall(function(...)
		
		local Dbg = debug.info(i, 'f')
		
		if Dbg then
			table.insert(DebugFuncs, Dbg)
		end
		
	end)
end


for i, v in next, Environments do
	warn(v.lol)
end

for i,v in next, DebugFuncs do
	warn(getfenv(v).lol)
end

local NameCall

xpcall(function(...)
return game:GetService('ioasdfhp')	
end, function(a0)
	
	NameCall = debug.info(2, 'f')	
	
end)

warn(getfenv(NameCall).lol)```

What exactly do you mean by an environment that won’t be modified by the original environment? What’s the purpose for this?

You can just set up a custom table of environment items:

local env = {
    ["print"] = print,
    ["setfenv"] = setfenv
}

setfenv(1, env)
setfenv(0, env)

Its for experimenting and it needs to be an actual environment. I cannot create a custom one as the code underneath the checks can change.

I would also like for you to elaborate on what this means. An environment contains all of the identifiers that are bound in the current scope, so if you bind a new identifier (e.g. make a local variable) then that will update the current environment.

If you want to create a snapshot of the current environment that will not be modified with new identifiers, then you could copy the current environment into a separate table.
