Hi,

Say I have the following:

for i=1,20 do
	local Item = table.deepcopy(data.raw.item["iron-chest"])
	Item .name="bio-"..Item .name.."-"..i
	data:extend({Item})
end

I have a table, created_items and I want it to look like this:
global.Created_Items = {
"bio-iron-chest-1",
"bio-iron-chest-2",
"bio-iron-chest-3",
"bio-iron-chest-4",
---
"bio-iron-chest-20
}

How would I populate the table dynamically with the item names created?

Thanks,.

Code: Select all

local foo = {}
for i=1,20 do
	local Item = table.deepcopy(data.raw.item["iron-chest"])
        local name = "bio-"..Item .name.."-"..i
	Item.name = name
        foo[#foo+1] = name
	data:extend({Item})
end

Is it possible to create a global table in the Data.lua stage, not Control?

No. But you don't need to. Any variable declared without local scope is accessible to all mods during each of the data stages.

So if I declare a table of functions in data.lua:

Code: Select all

deadlock = {} -- not local
function deadlock.hair_styling(parameters) ... end
function deadlock.shampooing(parameters) ... end
function deadlock.buzzcut(parameters) ... end

then any other mod that loads after mine can access those functions in their own data.lua code. Users should check they exist before calling them, obviously.

Alternatively you can set up a separate file:

Code: Select all

-- sometable.lua
local important_table = {
	biscuits = 79,
	oranges = 23,
	cheese_on_toast = 54,
}
return important_table

and then any mod can load up that table at any time with a require:

Code: Select all

-- mymod.lua
local my_important_table = require("__DeadlockImportantTables__.prototypes.sometable")

Thanks for the information Deadlock.
I did not know all this!

Just to avoid misleading - you don't need the __ModName__ prefix in a require() if it's a file from within the same mod, only if it's a file from some other mod. But you can use this method to have "library" mods which provide functions and/or data tables to a bunch of other mods.
