I came across two different statements that left me confused.
obj = {}
function obj.Create(name)
end
function obj:GoGoGo(name)
end
What is the difference of the function declared with the . (dot) and : (colon)?

The first is the member operator, it only separates who the role belongs to.
The second is a syntactic sugar, it is the same as:
function obj.GoGoGo(self, name)
end
Then it just puts one more parameter to get the object and give it a more OOP notation for the language. The same as many other languages make it a bit more automatic.
Call:
var x = obj
x.GoGoGo(10)
Actually the call will be:
obj.GoGoGo(x, 10)

The "colon" is used to call self as the first parameter of the function.
So obj:GoGoGo(name) should be the same as obj.GoGoGo(obj, name) .
I saw this in an OS response a while ago, but I did not find it.
