Questions about lua functions

[SnakeFist]

Hi no more setup questions I swear lol

I am looking over the lua code for TFS in the "data" folder and I have a question about the functions used in them. Specifically I want to be able to find where the definiions of these functions are delcared/stated. For example in the "Poison_wall_run.lua" file it uses two functions
The "onCastSpell" function and then "conjureItem" function.

function onCastSpell(creature, variant)
    return creature:conjureItem(2260, 2289, 4)
end

I want to be able to find the definitions of these functions so I can better understand their parameters and functionality. That way I can write my own scripts with a better understanding.

conjure item is in the spells lib folder.

I'm not entirely sure for onCastSpell..
But here

and 3 or 4 times in spells.h

For most everything you can find it in a couple of spots.

source files..
luascript.cpp -- all the lua functions
const.h -- sometimes things are thrown in here
enums.h -- if I can't find it anywhere else, it's usually here

data folder
data/lib/core -- for most of the custom functions
data/events/scripts -- for 'triggers', like onLook, onMove, onGainExperience, onSpawn

Anything else, just look to the source files, and do a search of the term you're looking for.

I've never understood c++ very well, and don't understand the logic for how it's sorted into different files..
So can't really help further on that front.
