SavedVariablesPerCharacter

[Benalish]

I was able to successfully create the file to save the variables of my addon.

## SavedVariablesPerCharacter: MyAddon_Settings

But if I want call these variables every time I load the addon, what should I do?

This should help you.

I cleaned up that wiki page some to remove some really outdated information, so it should be relevant again now. If you read it before now, I'd suggest going back to re-read it, and then removing any references to the VARIABLES_LOADED event from your addon (use ADDON_LOADED where arg1 is the folder name of your addon instead) and probably removing PLAYER_LOGOUT (it's completely unnecessary for the vast majority of addons).

Also, if you want to use a table to hold multiple variables, here is a simple function you can use to initialize your default values. It works no matter how many levels of sub-tables are in your defaults.

-- Define your default table:
local MyDefaults = {
	enable = true,
	showTheThing = false,
	x = 47,
	foo = "bar",
	t = {
		[12] = "twelve",
		[68] = true,
		cats = "meow",
	}
}

-- This function will make sure your saved table contains all the same
-- keys as your table, and that each key's value is of the same type
-- as the value of the same key in the default table.
local function CopyDefaults(src, dst)
	if type(src) ~= "table" then return {} end
	if type(dst) ~= "table" then dst = {} end
	for k, v in pairs(src) do
		if type(v) == "table" then
			dst[k] = CopyDefaults(v, dst[k])
		elseif type(v) ~= type(dst[k]) then
			dst[k] = v
		end
	end
	return dst
end

local addon = CreateFrame("Frame", "MyAddon")
addon:RegisterEvent("ADDON_LOADED")
addon:SetScript("OnEvent", function(self, event, arg1)
	if event == "ADDON_LOADED" and arg1 == "MyAddon" then
		-- Call the function to update your saved table:
		MyAddonSavedVariables = CopyDefaults(MyDefaults, MyAddonSavedVariables)
		-- Unregister this event, since there is no further use for it:
		self:UnregisterEvent("ADDON_LOADED")
	end
end)

MyAddonSavedVariables is the file specified in line ## SavedVariablesPerCharacter:?

There is no control over the actual file it writes to or where it's located, just what global variables WoW stores in it. To shorten Phanx's explanation, the SavedVariablesPerCharacter directive just tells WoW what globals to save for your addon. These globals will be available when ADDON_LOADED fires for your addon.

[Benalish]

local addon = CreateFrame("Frame", "MyAddon")
addon:RegisterEvent("ADDON_LOADED")
addon:SetScript("OnEvent", function(self, event, arg1)
	if event == "ADDON_LOADED" and arg1 == "MyAddon" then
		-- Call the function to update your saved table:
		MyAddonSavedVariables = CopyDefaults(MyDefaults, MyAddonSavedVariables)
                print(MyAddonSavedVariables)
		-- Unregister this event, since there is no further use for it:
		self:UnregisterEvent("ADDON_LOADED")
	end
end)

This code print the valor (?) of MyAddonSavedVariables. But if I write the print function outside this, the code doesn't work

local addon = CreateFrame("Frame", "MyAddon")
addon:RegisterEvent("ADDON_LOADED")
addon:SetScript("OnEvent", function(self, event, arg1)
	if event == "ADDON_LOADED" and arg1 == "MyAddon" then
		-- Call the function to update your saved table:
		MyAddonSavedVariables = CopyDefaults(MyDefaults, MyAddonSavedVariables)
		-- Unregister this event, since there is no further use for it:
		self:UnregisterEvent("ADDON_LOADED")
	end
end)

print(MyAddonSavedVariables)

Is the use of:

PLAYER_LOGIN

similar ?

So I can save to check with ADDON_LOADED the arg1 ...

Yes, though "MyAddonSavedVariables" is a variable name, not a file name, and you can specify it in either the SavedVariables field or the SavedVariablesPerCharacter field, depending on whether you want all of the user's characters to share a single copy of the variable (so changes made on one character would apply to all characters) or each have their own copy (so changes made on one would not affect any others).
