SavedVars and functions

[tiomun]

Still very new to lua so its probably all me lol

I am having some issues dealing with ZO_SavedVars. for example, I constantly receive a stack traceback error on the line for event manager. I believe I have a issue with how I am recalling the values from ZO_SavedVars.

So far google has not been friendly to me with this project. I have a tough time telling the lua code apart from apy function events and w/e else there is in code samples I'm referencing from multiple addons. Any help/tips is apreciated

-- Default Saved Variables
MMO.defaults = {
    -- Bag
    OverideBag = true,
    -- Map
    OverideMap = true,
    -- ActionBar
    OverideActionBar = true,
    -- Mouse
    OverideMouse = true
    
}
 
-- Hook initialization onto the EVENT_ADD_ON_LOADED listener
EVENT_MANAGER:RegisterForEvent( "MMO" , EVENT_ADD_ON_LOADED , MMO.Initialize )
 
function MMO.Initialize( )
 
    -- Register the slash command handler
    SLASH_COMMANDS[MMO.command] = MMO.Slash
        
    -- Load saved variables
    MMO.Vars = ZO_SavedVars:New( 'MMO_VARS' , math.floor( MMO.version * 100 ) , nil , MMO.defaults )
    
    if (MMO.Vars.OverideBag == true) then   
        MMO.bag()
    end
    
    if (MMO.Vars.OverideActionBar == true) then 
        MMO.actionbar() 
    end
    
end

What is the stack traceback error you are getting ?

That may help highlight where things are going crazy on you.

From my point of view its fairly vague. Unless theirs a better way of loging errors besides what comes up in the UI?

Checking type on argument callback failed in ScriptEventManagerRegisterForEventLua
stack traceback:
	[C]: in function 'RegisterForEvent'
	user:/AddOns/mmoui/mmoui.lua:27: in function '(main chunk)'

Theirs about 10+ lines of commenting nonsense above what I posted in the actual file so error line 27 is line 15 in the sample code above

I was able to make some progress on this just with trial and error.

Basically I Changed the function names to MMO_xxx() Insread of MMO.xxx(),
added local infront of each function,
and Removed the RegisterForEvent and added a simple function call to initialize at the end.

-- Default Saved Variables
MMO.defaults = {
    -- Bag
    OverideBag = true,
    -- Map
    OverideMap = true,
    -- ActionBar
    OverideActionBar = true,
    -- Mouse
    OverideMouse = true
    
}
 
local function MMO_Initialize()
 
    -- Register the slash command handler
    SLASH_COMMANDS[MMO.command] = MMO_Slash
        
    -- Load saved variables
    MMO.Vars = ZO_SavedVars:New( 'MMO_VARS' , math.floor( MMO.version * 100 ) , nil , MMO.defaults )
    
    if (MMO.Vars.OverideBag == true) then    
        MMO_bag()
    end
    
    --if (MMO_Vars.OverideActionBar == true) then    
        --MMO_actionbar()
    --end
    
end
 
local function MMO_Update()
 
end
 
local function MMO_Slash( text )
    MMO_Message()
end
 
local function MMO_Message()
    d( "You are using ".. MMO.name .. " version " .. MMO.version )
    d( MMO.name .. " configuration settings are in the game settings interface!" )
end
 
MMO_Initialize()

This worked well while I had the call to the functions MMO_bag() commented out much like MMO_actionbar() is commented out.

MMO_bag() is in a separate file functions.lua at the moment whether it has any code in the function or not it throws this new error

user:/AddOns/mmoui/mmoui.lua:23: function expected instead of nil stack traceback: user:/AddOns/mmoui/mmoui.lua:23: in function 'MMO_Initialize' user:/AddOns/mmoui/mmoui.lua:45: in function '(main chunk)'

and the code for function.lua

local function MMO_bag()
--[[--
    if BAG == nil then 
        local BAG = ZO_PlayerInventoryBackpack
        BAG:SetCenterColor(0,0,0,0.5)
        BAG:SetTexture(CT_BACKDROP)
        BAG:SetEdgeColor(.1,.1,.1,1)
        BAG:SetEdgeTexture("",8,1,2)
    end
--]]--
end

Theirs something different about lua that I cant wrap my head around. basic to php and most languages give me little trouble. I am definitely missing something with how the functions work, or variable get passed around. lua examples I see online look very little like what is used in these addons....

Ok, I think I can see where you are going wrong.

If you bear in mind that some information is only accessible after the addon is loaded or the player is activated things will become easier to implement.


If you take a look at my gatherer addon you will see that at the top of the file I have some addon variables and at the bottom I have some functions that are using the event system and are called by the event system. You could almost copy those and just adjust for your addon to get it to work.


Try something like the following.


local addon_name = "..."
local addondata = {}


local function init_addondata()
addondata=zo_savedvars:new(....)
end


local function player_activated(eventid)
--Player is active and most things are available now
end


local function addon_loaded(eventid, addon)
if addon == addon_name then init_addondata()
EVENT_MANAGER:RegisterForEvent(addon_name,EVENT_PLAYER_ACTIVATED,player_activated)
end
end


EVENT_MANAGER:RegisterForEvent(addon_name,EVENT_ADDON_LOADED,addon_loaded)




Hope that helps. I use this as the base of all my addons.

That was a big help I do not have any errors showing up any more, and I think I have a bit of a grasp on the functions now... maybe... let me know if any of my commenting or anything looks off.

However, I cant get the slash command to work. haven't gotten past that point yet.

having "SLASH_COMMANDS[addonCommand] = addon_slash" in the init function doesn't work anymore, and it wont work if moved to any of the other functions....

Sorry to be such a noob on all this, and thanks again for the help.

local addonName = "MMOUI"
local addonCommand  = "/mmo"
local addonVersion  = 0.01
local addonData = {}
 
-- Default Saved settings
addonData.defaults = {
    -- Bag
    overideBag = true   
}
 
-- Initialize addon data
local function init_addondata()
    
    -- Slash command handler
    SLASH_COMMANDS[addonCommand] = addon_slash
    
    -- Load saved variables
    mmoVars = ZO_SavedVars:New( 'MMOUI_VARS' , math.floor( addonVersion * 100 ) , nil , addonData.defaults )    
 
end
 
-- Addon is active and can call runtime functions
local function addon_activated( eventid )
    -- do stuff
    --if (mmoVars.overideBag == true) then
        --mmo_bag()
    --end
 
end
 
-- Load addon
local function addon_loaded(eventid, addon)
    
    -- if addon is for this script trigger init_addondata
    if addon == addon_name then init_addondata()
        -- trigger player activated passes this eventid to addon_activated function
        EVENT_MANAGER:RegisterForEvent(addonName,EVENT_PLAYER_ACTIVATED,addon_activated)
    end
        
end
 
local function addon_slash( text )
    d( "You are using ".. addonName .. " version " .. addonVersion )
    d( addonName .. " configuration settings are in the game settings interface!" )
end
 
-- trigger addon_loaded function, passes this eventid to function
EVENT_MANAGER:RegisterForEvent(addonName,EVENT_ADD_ON_LOADED,addon_loaded)
