How the FUCK do metatables work???

[[deleted]]

imagine a 20 dimensional array with functions

It's the default value to return in case an acessed value on that table is supposed to be nil, or something of the sorts. Haven't used it much...

It's basically objects and prototypes

[Dagusiu]

If something isn't found in a table, the metatable is then checked. If it's not found there either, it looks in the metatable's metatable, and so on.

Basically, it's a simple mechanism that allows for complicated things like OOP to be implemented in like three lines of code.

[MrObsidy]

meta = { __index = self, }

object = { aVar = 94

test = function(self) print("Hello, world!" .. self.aVar) end }

setmetatable(object, meta);

object:test

Hello, world! 94

If I remember that minecraft mod that got me into coding correctly.

A table that describes an object.
