I’ve seen some module scripts that use module: or module. to define their functions, is there any difference between the two? Does it matter which should be used?
Example:
module = {}
function module:test()
-- Or
function module.testing()
return module
Dots for libraries, colons for objects.
That’s the convention roblox uses for its functions, so I stick to it.
No. The colon syntax is convenience only. Doing someTable:Method("hello") is the same as someTable.Method(someTable, "hello"). In the same way,
function module.test(self)
print(self)
end
Is literally the same as
function module:test()
print(self)
end
As in, lua adds another parameter automatically. You can define one and call the other, whatever.
