Given a display group, theGroup, that has been declared in a module, game.lua, what’s the syntax to make that group accessible in another module, ship.lua
In ship.lua, I tried…
local theGroup = require("filepath.game").theGroup
…but that didn’t work. Any recommendations?
Hi @Dotnaught,
You may want to consider the “globals that aren’t actually globals” method of accessing variables/objects across scenes and modules. Maybe you already know this method, but just in case, here’s a tutorial on it:

Thanks, Brent. Unfortunately, refactoring isn’t practical in this instance. Is there a way to make a specific display group accessible from a separate module? I suspect I could do it indirectly using a parent reference off an object that’s in scope, but I’m not sure how to then refer the right display group if it exists inside a parent group with other objects.
Fully understood (no refactoring). I think this should work for you:
Let’s assume your “game.lua” module looks something like this (or can be adapted similarly):
[lua]
–game.lua
local M = {}
local group = display.newGroup()
print( group )
M.group = group
return M
[/lua]
And you require it like normal:
[lua]
–ship.lua
local gameModule = require( “game” )
[/lua]
The following should get the group ID:
[lua]
print( package.loaded[“game”].group )
[/lua]
Give that a test and see if the IDs match. I had to tweak and assemble this from some project code I had on the side, so hopefully I didn’t type anything wrong.

Awesome, thanks, Brent.
