What is a Scene, the SceneManager and other concepts

[Randactyl]

Continuing with localization, I like to have all of my strings in the same file so they are all in the same place when I need to edit them. Then I can use metatables to set a fallback option if I haven't gotten a particular string translated yet.

local strings = {
    ["de"] = {
        ["SI_MYADDON_NAME"] = "My German Addon name",
    },
    ["en"] = {
        ["SI_MYADDON_NAME"] = "My Addon name",
        ["SI_MYADDON_GENERAL_OPTIONS_HEADER"] = "General Options",
    },
}
 
setmetatable(strings["de"], {__index = strings["en"]})
 
local function AddStringsToGame()
    local lang = GetCVar("language.2")
    if strings[lang] == nil then lang = "en" end
 
    for i,v in pairs(strings[lang]) do
        ZO_CreateStringId(i, v)
    end
end
 
AddStringsToGame()

After the index metatabe is set, strings["de"] essentially becomes a union of the original strings["de"] and strings["en"] with any matching keys pulled from strings["de"] rather than strings["en"]:

strings["de"] = {
    ["SI_MYADDON_NAME"] = "My German Addon name",
    ["SI_MYADDON_GENERAL_OPTIONS_HEADER"] = "General Options",
}

As for exactly why this works or what else you can use metatables for, I couldn't tell you. Metatables are basically magic to me right now

I think making the decision to use this over votan's SafeAddString example really just comes down to personal preference. I suppose my method hogs more memory, but that shouldn't be an issue unless there are a lot of strings. If it did become an issue you could just nil the local strings table after the necessary ones were added to the game.

@Randactyl that's not how it works.

strings["de"] is still the same table. The metatable's __index provides fallback values for missing keys. But it's only scanned when you explicitly request a missing key, e.g.
strings["de"]["SI_MYADDON_GENERAL_OPTIONS_HEADER"]. Iterating over it with next/pairs will only see SI_MYADDON_NAME, because that's the only key in the table itself.

To make it work, you need to iterate over the "en" table:

for k in next, strings["en"] do
    ZO_CreateStringId(k, strings[lang][k])
end

On a positive note, you don't have to clean the local strings table -- it should be garbage-collected afterwards.

Hmm alrighty then, thanks!

I know this thread is old but my problem is quite related to the scene manager. It's acting very funny right know.

What I am doing:

-- self.aura[auraName] is a top level control

self.aura[auraName].sceneFragment = ZO_SimpleSceneFragment:New(self.aura[auraName]);
HUD_SCENE:AddFragment(AuraMastery.aura[auraName].sceneFragment);

Create the fragment and assign it to the HUD_SCENE.



I am using a registered update handler to listen for desired (de-)buffs. This handler simply looks at a specified frequency if the effect is present and sets the boolean variable 'display' to true or false depending on wether the effect is present or not

HUD_SCENE:RemoveFragment(AuraMastery.aura[auraName].sceneFragment);		
if (display) then
    HUD_SCENE:AddFragment(AuraMastery.aura[auraName].sceneFragment);

    (...)

Remove set fragment if the buff/debuff is not present, then check if it is present (display = true). IF it is present, add the fragment to the scene again.

In clearer words, I:

1. create a top level control (TLC)
2. make it a shard
3. assign this shard to HUD_SCENE

4. updating handler (updating every 5frames):
check if aura is present
=>
if (not present): remove the shard from HUD_SCENE
else add the shard from HUD_SCENE






My problem: The control is visible if I start the game. To make it work I have to /reloadui, then everything runs flawlessly. Any ideas?
