Need help loading SavedVariable setting.

I searched around and I have tried a dozen things but somehow, I can't get it to work.
I can get the value 1 or 3 saved, but somewhere with reading it back, it goes wrong but I am unsure why.

Here is the AddOns code:

Code:



WorldMapFrame:SetScale(0.8)

Code:

WorldMapFrame.BlackoutFrame.Blackout:SetAlpha(0)



if SimpleMap == 1 then

    PlayerMovementFrameFader.AddDeferredFrame(WorldMapFrame, .3, 3.0, .5)

elseif SimpleMap == 3 then

    PlayerMovementFrameFader.AddDeferredFrame(WorldMapFrame, 1, 3.0, .5)

end





WorldMapFrame.ScrollContainer.GetCursorPosition = function(f)

    local x,y = MapCanvasScrollControllerMixin.GetCursorPosition(f);

    local s = WorldMapFrame:GetScale();

    return x/s, y/s;

end



local function SimpleMapCommands(msg, editbox)

  if msg == 'off' then

    print('SimpleMap fade has been turned off.')

    PlayerMovementFrameFader.AddDeferredFrame(WorldMapFrame, 1, 3.0, .5)

    SimpleMap = 3

  elseif msg == 'on' then

    print("SimpleMap fade has been turned on.")

    PlayerMovementFrameFader.AddDeferredFrame(WorldMapFrame, .3, 3.0, .5)

    SimpleMap = 1

  end

end





SLASH_SMFADE1 = '/smfade'



SlashCmdList["SMFADE"] = SimpleMapCommands

And here is the .toc.

Code:



## Interface: 11302

## Version: 1.1

## Title: SimpleMap

## Notes: Smaller worldmap and it fades the map when moving

## Author: Sojiro84

## Dependencies: Blizzard_WorldMap

## SavedVariables: SimpleMap



SimpleMap.lua

Code:

The savedvariable contrains either "SimpleMap = 1" or "SimpleMap = 3".

Somehow the following doesn't trigger:

Code:

if SimpleMap == 1 then

    PlayerMovementFrameFader.AddDeferredFrame(WorldMapFrame, .3, 3.0, .5)

elseif SimpleMap == 3 then

    PlayerMovementFrameFader.AddDeferredFrame(WorldMapFrame, 1, 3.0, .5)

end

I tried "AddOn Loaded" events and saying that variable "SimpleMap = SimpleMap" so that the value is loaded but nothing.

Clearly SimpleMap isn't being assigned with the SavedVariable value.

Can anyone help me?

It feels like the solution should be simple but I never made a WoW AddOn before so a bit difficult for me!

Saved variables are loaded after the addon code is executed
They cannot be accessed immediately, and will overwrite any "defaults" the addon may place in the global environment during its loading process.

Yeah, I found that page and many others. I played around with those statements but it ended up breaking the whole addon or still not loading my value.

What am I missing?

The addon loading process loads the file(s), executes the stuff that is placed in the main code-flow and after that only events can trigger execution of your code.

Any code that is executed before ADDON_LOADED with the argument of your own addon cant access your SV.
You have to listen for this event. And only after this event occurs make sure it is fired for your addon and setup your stuff after that.

Lua Code:

WorldMapFrame.BlackoutFrame.Blackout:SetAlpha(0)
 
WorldMapFrame.ScrollContainer.GetCursorPosition = function(f)
    local x,y = MapCanvasScrollControllerMixin.GetCursorPosition(f);
    local s = WorldMapFrame:GetScale();
    return x/s, y/s;
end
 
local function SimpleMapCommands(msg, editbox)
  if msg == 'off' then
    print('SimpleMap fade has been turned off.')
    PlayerMovementFrameFader.AddDeferredFrame(WorldMapFrame, 1, 3.0, .5)
    SimpleMap = 3
  elseif msg == 'on' then
    print("SimpleMap fade has been turned on.")
    PlayerMovementFrameFader.AddDeferredFrame(WorldMapFrame, .3, 3.0, .5)
    SimpleMap = 1
  end
end
 
 
SLASH_SMFADE1 = '/smfade'
 
SlashCmdList["SMFADE"] = SimpleMapCommands
 
local f = Createframe("Frame")
f:SetScript("OnEvent", function(self, event, ...)
    if SimpleMap == 1 then
        PlayerMovementFrameFader.AddDeferredFrame(WorldMapFrame, .3, 3.0, .5)
    elseif SimpleMap == 3 then
        PlayerMovementFrameFader.AddDeferredFrame(WorldMapFrame, 1, 3.0, .5)
    end
end)
f:RegisterEvent("PLAYER_LOGIN")

Thank you both for the suggestions, but even with my whole script inside the addon_loaded event (with checking for my addon name), it still doesn't work.

Hell, my whole AddOn just doesn't work at all when I do it inside/after the addon_loaded event.

It was worth a shot.

SavedVariables are initially nil so if they require meaning other than that then you need to initialise them first time in.

PLAYER_LOGIN event

Lua Code:

if not SimpleMap then
    SimpleMap = 1
    -- or SimpleMap = {}
    -- or SimpleMap = Whatever
end

Or, an edit to Fizzlemizz's code (that is more relevant to what you are learning):

Lua Code:

local f = CreateFrame("Frame")  --oh, and there was a typo here
f:SetScript("OnEvent", function(self, event, addon)
    if addon == "YourAddonNameHere" then
        if SimpleMap == 1 then
            PlayerMovementFrameFader.AddDeferredFrame(WorldMapFrame, .3, 3.0, .5)
        elseif SimpleMap == 3 then
            PlayerMovementFrameFader.AddDeferredFrame(WorldMapFrame, 1, 3.0, .5)
        end
    end
end)
f:RegisterEvent("ADDON_LOADED")

I like PLAYER_LOGIN because you don't have to check for an addon name, it only fires once and that one time after all addons have loaded and before PLAYER_ENTERING_WORLD. Then again, I'm lazy :)

Thanks all for the help. I managed to get it working with the "PLAYER_LOGIN" event!
