[Solved] Lua Modulo Weird Behavior

[Killparadise]

Hello! I'm writing out some scripts but it seems like when I try to run a modulo I get some weird behavior, for example:

a % b - Causes a syntax error
a % n - Crashes the world editor
a % 1 - Saves fine

Are we not able to use variables with the mod functionality?

Full Example that gives a syntax error:

  local function mod(a, b)
    return a % b
  end

Gives following syntax error:

I tried to do a little searching and did discover that the % sign can cause crashing but that looks like with string concatenation, is this a similar problem?

Thank You!

Is that code of yours residing in the "map header" section of WorldEdit? Afair (but can't find a quick source atm) you need double % in the header but not in the normal triggers section.
Also [General] - Trigger editor and percent sign

Yes, this is one of the Lua issues in WC3 as WC3 uses % as escape character.
See the Lua tutorial A comprehensive guide to Mapping in Lua - section 'Lua Fundamentals', subsection 'Strings and Numbers'

Gah, I had these open and everything, I just didn't read far enough down, thank you!
