WHY DOES SELF.BACKUPRETRIES = nil? I’m using this correctly. Self doesnt even print the same thing based on whatever uses it. help

#3

Would it be possible to see the code where you create the DataStore object? Your DataStore.new() function or equivalent.

#4

Yes it’s all right there. Also if you wish to see more I left a download that has the 2 scripts. The Datastore.new is at the very top. When the function is called at the very beginning

#5

Sorry in advance for the lengthy answer

I’m looking through your DataStore2 script, I can’t find any method which returns self.

From what I’ve seen so far, this is required. I might be wrong about that however.

Usually the code is something along the following lines:

local MyObject = {}
MyObject.__index = Object-- Tell missing indexes to search through this object

function MyObject.new()
    local self = {} -- Create self
   
    setmetatable(self, MyObject) -- Set references to Object within 'self'
    return self -- Return this specific instance of the MyObject object
end

return MyObject

You may already know this, and I might be missing another crucial detail; but the following hopefully explains the difference between functions with . and : respectively.

-- Lua
function MyObject.foo()
    -- This function does *not* know about self.
    -- Works more or less the same as a regular module script.
        -- (will act the same no matter which MyObject called it)
    ...
end

function MyObject:bar()
    -- This function *does* know about self.
    -- Can be seen as a function of this MyObject instance
        -- (may act differently depending on which MyObject called it)
    ...
end

I’m not sure how familiar you are with other programming languages, but if you know Java this might be able to help:

public static void foo() {
    ...
}

public void bar() {
    ...
}

If any of this is incorrect, feel free to correct me.
