If I have a custom handler for an object and I have a function within the handler, how would I get the handler variable to the function?
Example:

handler = {
handlerFunction = function()  end,
}

In the above example, how would I get handler to handerFunction?

local handler = {}

handler.handlerFunction = function() return handler end

Wow...should have thought of that...

I am not to sure on this, i have had similar problems, one theoretical sollution i thought of was to set the function environment of all functions to the handler and then give the handler a metatable with __index = _G.

but you will have to test it, maybe someone else has a better sollution

this works if you have one object with that name, but wont work if all objects are in the same array probably, maybe my sollution will work

Uh, no, you might want to review scope, upvalues, and closures. It'll work anywhere as long as it's set up that way.
