(if i == nil) won't work

Hello everybody

I'm just experimenting with my code. And i really don't know why it's not working correct.

while true do

local i

if i == nil then
  i = 0
end

os.sleep(1)
rednet.broadcast(sFWName)

event, id, text = os.pullEvent("rednet_message")

if text == "message_received" then
  print("Message received")
  break
else
  print("Message not received")
  i = i + 1
end

if i == 2 then
  i = nil
  break
end

end

Even if i contains 1, the code executes this part of the code. The Problem is, that it never gets out of the loop.

if i == nil then
  i = 0
end

Please can you explain why that code isn't working?

Uhm I think since its a local variable made inside the loop it get cleaned once the loop ends?

So put local i before the while and remove it from inside the loop

Oh

Yeah, that was really a dumb fault.
In every singe repeat of the loop the local variable i gets new "initialized".

Well it forgets about local variables in every new loop if they were defined in the loop i think? Not sure on that one but i think so :P/>/> Will test that~

edit: yes thats how it works

The local variable is local to the loop, so when it restars the variable is "created" again.

Yeah if you create it that is, if not its just forgotten
