initialize variable

[chriss]

hi all

how can i initialze a variable just once and not always the script is triggered?? i want to set a variable only if it is nil (so on startup) but not allways if the script is triggered.

thx and greetz

x = x or 0


If the variable x exists then it will equal itself, otherwise will be set to 0. The digit 0 can be anything; you can replace that with a string in quotes as well.

I didn't know that - glad I read all the new posts each day...

For a more readable version:



if not x then
x = 0
end


will do the same.
