Can someone explain me the use of dummy functions?
1-why/when to use it
2-is it necessary to use a @? because i've tried without it and it still works, so whats that for?
3- how it changes the C++ code behind the scene? (not that i would understand everything, but..)
Thanks in advance!
EDIT: i had a look at some threads and the help file, but couldn't find what I'm looking for about dummy functions :/
