functions from other addons

[barbol12]

hello, apparently i cant get this to work..

i have an addon that has a few functions on them(this addon loads before main addon). But when i try to use them in my main addon it doesnt work.

i was just wondering, what way do i need to go to be able to get the function(s) from my other addon???

nvm ignore post... i got it figured out, just needed to make an engine duh!

The functions have to be global.

Usually best way is to create functions like this:

local function bla(blubb)

but you need

function YOUR_ADDON_bla(blubb)

I would advise you, to prefix the functions with your addon's name, to make sure they are unique in the global namespace. Otherwise you could taint other addons or even the WoW-API-functions. Just as it is good practice with global variables.

ya.. but i found an easy way around it all i just made an engine for my entire addon(s)

A tip, if you put for example this on top of the lua files in your addon:
local addonName, addonTable = ...

The addonName will be the addon name (folder) and addonTable is a table shared by the entire addon locally. Hence if you got several files loading and you in the first one define:
function addonTable:Test() end

Then this function can be called by the later lua files by doing addonTable:Test() of course. Note that this may strain performance if you call a function from a table many times at once, hence this is a bit better (I heard, not tested):
local Test = addonTable.Test
Now calling Test() a bunch of times should be as if the function was created using "function Test() end"

I am sure some of my friends will correct me if I am wrong. :P

Good example that i have for my UI

AftermathhUI = {}
 
 
AftermathhUI.Func = ...... -- this function can be meantion in anywhere within your texts
 
 
AftermathhUI["c"] = { -- this needs to be loaded before ANYTHING.
 
        ["mybordercolor"] = {.25, .25, .25}
        ["disablemything"] = false,
 
}
 
local Frame = ("Frame", nil, UIParent)
frame:SetBackdropColor(unpack(AftermathhUI.c.mybordercolor)) -- this unpacks the color
 
if AftermathhUI.c.disablemything == false then
 
.......
 
end

Hope this help you abit forward

I pretty much do this everytime I feel I need to have several files..

File 1

local ADDON, ns = ...
 
local settings = {}
 
settings.color = {
    -- stuff here
}
 
ns.settings = settings

File 2

local ADDON, ns = ...
 
local settings = ns.settings
 
-- now I can use the settings (colors) here

However, he asked to have the function available in another addon, not in another file.

I would really like to know, what you mean by "engine" and how you go about it.
I had a similar problem some time ago (create one look throughout all my addons) and I go the way to create one addon which provides some functions to create borders and backgrounds and stuff and made the functions global.

For another addon you would have to use global variable, minimum one!
