clonefunction - Mintlify Starter Kit

Returns a copy of func that runs the same code, but is a separate function: clone == func is always false.

clonefunction(func: function): function

Works on Lclosures/CClosures. The bytecode is identical, so getfunctionhash(clone) == getfunctionhash(func). Mainly used to grab a clean copy of a function before some other script hooks it.
The clone keeps the original behavior, so calls through it bypass the hook entirely:

local cleanFunction = clonefunction(someFunction)
-- another script may hookfunction(someFunction, ...) later,
-- cleanFunction still calls the original.

Parameters

Parameter	Type	Description
`func`	`function`	The function to clone.

Returns

function - same code as func, with its own memory address.
Each call to clonefunction returns a new function - clone the same one 10 times, and you get 10 separate copies of it.

Example

local Old = clonefunction(print)
Old = hookfunction(print, function(...)
	if not checkcaller() then
		Old(...)
	end
	warn(...)
end)

print("Hello, World!")

local cloned_function = clonefunction(print)
local function loop()
	while task.wait() do
		if print ~= cloned_function then
			restorefunction(cloned_function)
			print("sad")

			break
		end
	end
end
task.spawn(loop)

local old; old = hookfunction(print, function(...)
	warn(...)
end)

local Lua_Closure = newlclosure(function()
	return "Hello, World!"
end)

local cloned_function = clonefunction(Lua_Closure)
if dumpbytecode(Lua_Closure) == dumpbytecode(cloned_function) then
	print(cloned_function)
end

Always check parameters and return values when working with this library function.
