lua attempt to call field 'createUDPSocket' (a nil value)

Question

I am writing a LUA script, when I run the program, this result as below:

socket = net.createUDPSocket()

attempt to call field 'createUDPSocket' (a nil value)

I have been searching for many website, there seems to no much details about that. Could anyone help?

Answer 1

That simply means that the createUDPSocket function does not exist. Without seeing your code, that is the most anyone here is going to be able to help you with.
