Need help with metatables

Help and Feedback Scripting Support

I was writing a new framework for my newer project but I’ve gotten into a big problem, I have been attempting to find a solution to this problem for the past few hours and I still have not a single clue what is causing this.
for some reason the methods aren’t copied
output:

db2
db21243×511 15.7 KB

the first table are the methods
the second table is the table after the meta was supposed to be copied

network.CreateConnection = function(self, connection_name, connection_type, connection_global)
    -- * Error check
    assert((typeof(connection_name) == "string"), GetErrorCode("Invalid Argument, Argument 1(connection_name): String expected"))
    assert((typeof(connection_type) == "string"), GetErrorCode("Invalid Argument, Argument 2(connection_type): String expected"))
    assert(((connection_global == true) and (IsServer)) or (connection_global == false), GetErrorCode("Invalid Usage, global connection can only be created from the server") )
    -- x assert((typeof(connection_name) == "boolean"), GetErrorCode("Invalid Argument, Argument 3(connection_global): Boolean expected"))

    elseif (this.Type == "Get") then
        -- * Overwrites the get function and replace it with the new function
        -- * Only one Function can exist at once, it's pointless to have two receivers
        -- *    then to have them return different arguments, only one would go through
        if (typeof(this.GetFunc) == "function") then
            warn("$m Warn: Existing function was overridden:", this.Name)
        end
        this.GetFunc = func
        this.Connection[this.ConnectMethod] = this.GetFunc
    end
end

im extremely sorry for the lack of explaination in this post, I’m exhausted and suffering from my back pain
I would appreciate any help

@ArkhieDev Good luck Bro. I just looked over the script and I am trying to figure out the problem but I don’t see an error. I will contact you if anything pops up, lol. :sob:

@ArkhieDev Would you have a problem if I copied the script and tried to look into it more?

Heyyy, thank you for offering for help! Although I already solved this myself
I replaced the __index method with this and It worked!!

connection_methods.__index = function(this, method)
    return function (this, ...)
        if connection_methods[method] then
            print("calling method", method, this.Name, this)
           return connection_methods[method](this, ...)
        end
    end
end

again, thank you for offering to help I appreciate it.
