Hi everyone,

I am using a file I found online to implement OOP in my game. This class file uses a metatable when defining a new class type.
I have a vector class that uses this and I am wondering how I can setup equality checking of two vectors together. I am not exactly keen on how metamethods work in order to figure this out on my own. Am I out of luck with the metatable being used already?

Code: Select all

function Vec2:__eq(rhs)
	return self.x == rhs.x and self.y == rhs.y
end

Beware of floating point precision issues.
