How to default a value?

Help and Feedback Scripting Support
#1

In this piece of code, I want to add a default value. But don’t want to bother with a long statement.
How am I suppose to accomplish this?

function Some (inv)
    asd = inv or true 
    print(asd)
end

Some(false)

It doesn’t give me false in the output.

can you tell us more? I don’t really understand your issue with that

What I want to do is I want to make the default value of “asd to true” if the inv doesn’t include any value so if The function doesn’t has any value I’ll make the asd = true but if it has any bool value then i’ll convert the asd to that value without making the code in multiple lines.

#4

so if the value in the function (inv) is empty(?) or doesnt equal to a certain value then set the asd to true, and if it has then set asd to the “inv” value? I understood correctly?

exactly, accurate! and remember I am passing only booleans not int nor strings

If you want to have a default parameter value, and assuming that “no value” means nil, you could do the following:

local function func(param)
    param = param == nil and true or param
    print(param)
end

func() --> true
func(false) --> false
func(100) --> 100
