Hello all,

I'm actually working on a big project (600 lines), and I have an error I don't understand.
ERROR: At line 538 permgCmd[ucmdLoop] is nil and I don't know why :/ .

Additional info:

NOTE: Never tested in-game, using CC Emulator

Thanks.

(Sorry for my bad english)

Oops, I missed one line in the post.

The pastebin doesn't seem accurate seeing as line 560 there's a print("564") and on what would be 561 based on that (or 561 in the pastebin) doesn't have any reference to permgCmd.

Modified. It's now line 538.

Line 546:

until ucmdLoop > #permgCmd + 1 or quitsc == true

The way I read it, that should be a "ucmdLoop == #permgCmd" there.

A "for" loop would be neater than "repeat...until":

for ucmdLoop=1,#permgCmd do
  sleep(0.1)  -- Only required if you're running a biiiiiig loop here.
  if permgCmd[ucmdLoop] == command then
    print (command.." founded in ID "..ucmdLoop.. ".")
    sleep(1)
    toreturn = ucmdLoop
    break
  end
end

And that's assuming you don't want to rebuild the table so's the key names match the commands you want to check, which'd allow you to skip the loop completely. To do it, you'd replace line 309 with:

permgCmd[line] = true

"permgCmd[command]" will then be "true" if "command" exists in that table.

Okay, but this don't have any link to this error?
Or I don't have understand.

EDIT: Okay, i have understand. Your But I still want to use index tables (entry1= "fff", 2= "rrr", 3= "ggg"...) instead of "variables tables" ("/com", "/set"...) / ("/com" = true, "/set" = true).
The thing I want to know is why at line 309 I fill up the table permgCmd and at line 538 permgCmd[1] is nil.

[Bomb Bloke]

permgCmd[ucmdLoop] would eventually be nil because you allowed ucmdLoop to get all the way up to #permgCmd+2.

If permgCmd[1] is nil then you've got more serious problems in addition to that.

Reading a bit further, I see the function that fills the table for you - readPermg() - is only called by that same function. Meaning it'll never execute. Not only that, but you appear to've put that function inside the processingPart() function, which should've been ended by the time you start defining the next one.
