Howdy all:

I was building a mission for Inferno last night, and as a certain scripted, chain-reaction explosion occurred, the game froze and I was greeted by this error message:

LUA ERROR: [string "deto-sct.tbm - On Frame"]:12: attempt to call method 'lower' (a nil value)

I asked my team-mates what this could mean, as my LUA knowledge is virtually nil value, but I was suggested to ask in open forum, and so I do.  Now, at the time, I was racing to evade an explosion which I knew was imminent, and was rear-viewing at the time.  The explosion caused some severe buffeting to my fighter prior to the freeze.  On a subsequent play-through, I kept on forward view and may have gotten some extra distance from the explosion, as I don't recall there being as much buffeting.  In any case, I got no repeat of the freeze that time.

Well, it sounds like you have an error on the 12th line of your $On Frame: hook, in deto-sct.tbm, involving a function/method called "lower" which is nil (Lua's name for "null").

[The E]

It would certainly help if we could see the script in question. Or if you could contact the scripts' original author. In other news, moved to modding, because this isn't a support topic.

[Nuke]

call it as string.lower()

its part of the lua string library so it needs the "string." prefix.

[Trivial Psychic]

Now, I already attempted to add "string." ahead of all instances of "lower()", as Nuke suggested, unfortunately, I was met with this error message:

LUA ERROR: [string "deto-sct.tbm - On Mission Start"]:11: function arguments expected near '.'

and then if I continue:

deto-sct.tbm(line 579:

Then:

deto-sct.tbm(line 580:

And:

deto-sct.tbm(line 582:

And:

deto-sct.tbm(line 584:

And:

deto-sct.tbm(line 586:

It would certainly help if we could see the script in question. Or if you could contact the scripts' original author. In other news, moved to modding, because this isn't a support topic.

I'm not sure about the script's original author, but I consulted with the Inferno team and have received permission to post the file contents... mainly because no-one seems to know what it really does and who put it in.

It seems you are using an old version of the flashy explosions script. You should update to the version used in the mediavps.

[Wanderer]

Unless some one seriously revamped the script that should not matter.

It seems to be failing on

Code: [Select]

str_S_class = o_ship.Class.Name:lower()Which is rather surprising, assuming all ship classes have names.

Adding there a string. does not help at all, it is legal in lua to use <string>:lower() instead of string.lower(<string>) calls just as well. Problem however is that not related (directly to that). For some reason ship classes name string does not seem to be valid (ie. gave nil).

You could try using

Code: [Select]

str_S_class = string.lower(o_ship.Class.Name)instead of

Code: [Select]

str_S_class = o_ship.Class.Name:lower()
Still got to think a bit for the actual cause of the problem.

[Nuke]

did the script make sure the ship was valid?

i think stringvar:lower() is acceptable, but i usually do string.lower(stringvar) instead. either one is legal though. but if stringvar is any type other than string you will get an error. i like to do something like:
if type(stringvar) == "string" then stringvar = string.lower(stringvar) end

thats the surefire, but expensive, way to make sure your stringvar is actually a string. but something like this:
if string then stringvar = string.lower(stringvar) end

might work so long as you make sure its either gonna be string or nil, in some cases it may end up being some other type, like a number (getting a boolean can be mis-interpreted either way and its something to watch out for), and that would be bad.

[Wanderer]

It should be

Code: [Select]

   n_ships = #mn.Ships
 
   for h = 1, n_ships do
      o_ship = mn.Ships[h]
      str_S_class = o_ship.Class.Name:lower()
Or that at least seems to be spot reported initially

[Trivial Psychic]

It seems you are using an old version of the flashy explosions script. You should update to the version used in the mediavps.

The team has now updated to the file from MV_Effects.3612, but I'm still getting the crash.

[Wanderer]

Unless some one seriously revamped the script that should not matter.

Do you use templates? Do you use oddly named ship classes? Have you run debugger?

[Trivial Psychic]

It would appear that the script has nothing to do with my issue.  I even deleted the file, tested the mission, and encountered the same crash.  I even tried shooting out all the exploding items before the event to destroy them would trigger.  I experienced no crashes at these.  What I did get the crash on however, was a ship arrival that was triggered to occur right afterwards.  I expect that I'm trying to trigger a sequence of events that creates a logic loop or something, which the debugger isn't configured to look for.
