(Excuse the double posting.)
I noticed another unrelated problem in the code.

Code: Select all

Mob = require "./Classes/Mob"
The module name format isn't good. This will try to load 'PathToProject///Classes/Mob.lua', which I guess accidentally works on Windows because Windows seems to accept multiple directory separators in a row. It should be like this:

Code: Select all

Mob = require "Classes.Mob" -- Use dot as the directory separator.
I think the Lua manual isn't good at describing this.

Hm! It works just fine on my Mint system, that's where I'm doing most of my dev work.

I guess it accidentally works on Mint too. It might work in all places LÖVE supports, but if you put this at the top of the module you should see the weird path that the module was loaded from:

Code: Select all

print(debug.getinfo(1).source) -- Will probably print @//Classes/Mob.lua
(Ignore the @ sign.)

It's more evident if you call require"./././Classes/Mob".

Also if you don't use a canonical path, you risk loading the same required file more than once. E.g. if you have this in req.lua:

Code: Select all

print("required")
and you require it differently in more than one place:

Code: Select all

require("req")

Code: Select all

require("./req")
you will get "required" printed twice, meaning the file will have been loaded and executed more than once.

The canonical path uses dots for path separators, is relative to the directory where main.lua is, and uses the same letter case as the filenames.
