Why the functions are passed as parameters? It's an advantage?

 

[copypaste_scripter]

Which one exactly

Why is like that and not like
function exemple_function()
-- code
end

Why function is passed as another function argument?

 

[copypaste_scripter]

no idea what u mean by passing, but function is "used" once by script, if it was used by command it would be given name as you wrote to "call" it when needed.
here, function is just getting value if player is playing by built in game activity library and returning value
i think i got it right, if not someone will correct me

Why the functions are passed as parameters?

Because the OnFrame function needs parameters like this

Why is like that and not like

In your screenshot, a lambda function is passed to OnFrame, it doesn't need a name. Instead of a lambda, you can also use a pre-initialized function by its name

Thank you, i didn't know this thing is named `lambda`. But how is possible to use that type of lambda functions in OnFrame? Because i tryed to do another script with a lambda function as argument, and it didn't work.

function a(func)
    print(type(func), func())
end

a(function() return "any value" end) -- a lambda will be passed to the function
