So, the three dots are an ellipsis. In functions, they are used as a substitute to having named parameters. For example:
local function foo (...)
print(#{...})--8
for _,v in pairs({...}) do
print(v)
end
end
foo("thy","they","2",121,343,4323,"fbi","boo")
the ellipsis is particularly useful when you are sending a lot of arguments to a function, and instead of having to create a parameter for every single argument you have. For Example:
game.ReplicatedStorage.Remote.OnServerEvent:Connect(function(...)
local a = {...} --table of arguments
print(a[1],a[3],a[2],a[6],a[9])
end)
