Annoying Unfixable Error

StormAlt-legacy · August 20, 2009, 1:22am

This error keeps popping up everytime I shoot my entity.

includes/extensions/table.lua:165: bad argument #1 to ‘pairs’ (table expected, got nil)

Paste your entity’s code here so we have a clue to what you are doing that might be raising the error.

Crazy_Quebec-legacy · August 20, 2009, 1:58am

What your error says is that somewhere in your code you’re giving the pairs function (for k,v in pairs(something)) a bad argument. That must mean this argument is not defined/does not exist.

Also when posting your code please place it inside [lua] tags so the indentation and readability remain.

StormAlt-legacy · August 20, 2009, 1:59am

Like, as in removed? I think that might be the case seeing as the base code is kind of old…however I don’t know where I would find the bad argument.

[editline]08:03PM[/editline]

Also, this strangely does not happen to my other entity that uses this base code as well…

Kogitsune-legacy · August 20, 2009, 2:04am

Or he’s using a function that expects a table and wasn’t given one.

[editline]02:06AM[/editline]

That ChooseRandom function expects a table.

You have:

ChooseRandom( self.Pain )

self.Pain is nil. You need to define it somewhere in your code.

StormAlt-legacy · August 20, 2009, 2:12am

Thank you Kogitsune, It’s working fine now sorry for the bother.
