Possible to check if player have DLC access?

[SnowmanDK]

I wonder if there is a function I missed that can tell me if a player have access to a specific DLC.
I need it to hide/show certain quests.

Lets say each DLC was given a number value, like this:
1 = Imperial City
2 = Orsinium
3 = Thieves Guild
and the function was like this:
isDLCAvailable(DLC number)
Returns true/false depending on if the player has access to that DLC.

Then I could do something like this:

If isDLCAvailable(2) then
-- show quests in the Orsinium dlc zone and subzones
end

The collections menu shows exactly what you ask for. Take a look at collections/keyboard/dlcbook_keyboard.lua and you will find that the function you are looking for is called GetCollectibleUnlockStateById and returns a CollectibleUnlockState.
The ESOUIDocumentation.txt shows that CollectibleUnlockState can be one of these three values:

• COLLECTIBLE_UNLOCK_STATE_LOCKED
• COLLECTIBLE_UNLOCK_STATE_UNLOCKED_OWNED
• COLLECTIBLE_UNLOCK_STATE_UNLOCKED_SUBSCRIPTION

Now you just need to figure out how to get the collectibleIds for the DLCs.

254 - Thieves Guild
215 - Orsinium
154 - Imperial City

For the list :

local name, _, numCollectibles, unlockedCollectibles, _, _, collectibleCategoryType = GetCollectibleCategoryInfo(COLLECTIBLE_CATEGORY_TYPE_DLC)
 
for i=1, numCollectibles do
    local collectibleId = GetCollectibleId(COLLECTIBLE_CATEGORY_TYPE_DLC, nil, i)
    local collectibleName, _, _, _, unlocked = GetCollectibleInfo(collectibleId) -- Will return true or false. If the user unlocked throught ESO+ without buying DLC it will return true.
    d("DLC ".. collectibleName .. "( ".. collectibleId .. ") unlocked : " .. tostring(unlocked))
end

Thanks for your replies
Didn't think about checking the collectibles functions

Now I just need to find out how to get the Thieves Guild Skill Line level...

[Ayantir]

for i=1, GetNumSkillLines(SKILL_TYPE_GUILD) do
    local skillLineName = GetSkillLineInfo(SKILL_TYPE_GUILD, i)
    if skillLineName == GetString(DESTINATIONS_DLC_SKILLLINE) then
        local GetNumSkillAbilities(SKILL_TYPE_GUILD, i)
        -- etc.
        break
    end
end

DESTINATIONS_DLC_SKILLLINE =

de = "Diebesgilde"
fr = "Guilde des voleurs"
en = "Thieves Guild"

Wouldn't it be better to check the first abilityId in each skill line? That way you are independent of translations.

It can change too.

They changed skills in IC (Racial passives).
They deleted the skillLine 2 in IC (Emperor) make the 3rd become the 2nd (Assistance moved from 3rd to the 2nd).
And they added a skillline in the 3rd position instead of the 4th with TG.
And for World it can change depending of skillline unlocking.
And for Tradeskills, skilllines are not even sames if you are starting game in EN , DE or FR.

And with a revamp, they can add skills too.

Plus, for 1 skill, you can have 12 abilityId. Per exemple here are abilityId of DK Skill 1 of Draconic Skillline (1st skill line).

[SKILL_TYPE_CLASS] = {
    ["Draconic"] = {
    [1] = {["skillPool"] = {
    [0] = {[1] = {["id"] = 29012,},[2] = {["id"] = 33652,},[3] = {["id"] = 33655,},[4] = {["id"] = 33658,},},
    [1] = {[1] = {["id"] = 32719,},[2] = {["id"] = 33662,},[3] = {["id"] = 33665,},[4] = {["id"] = 33668,},},
    [2] = {[1] = {["id"] = 32715,},[2] = {["id"] = 33671,},[3] = {["id"] = 33675,},[4] = {["id"] = 33679,},},
    },["at"] = ABILITY_TYPE_ULTIMATE,},

And with passive they can add unlimited #amount of passives ranks.

So yes, there is not real proper way to do it, you'll need to check at each new DLC.

You code returns the number of abilities in a skill line, not the level
But it got me started, and I ended up with this:

local skillLineLevel, DLC_TG_SkillLine = nil, nil
if localLanguage == "de" then
    DLC_TG_SkillLine = "Diebesgilde"
elseif localLanguage == "fr" then
    DLC_TG_SkillLine =  "Guilde des voleurs"
else
    DLC_TG_SkillLine = "Thieves Guild"
end
for i=1, GetNumSkillLines(SKILL_TYPE_GUILD) do
    local skillLineName = GetSkillLineInfo(SKILL_TYPE_GUILD, i)
    if skillLineName == DLC_TG_SkillLine then
        _, skillLineLevel = GetSkillLineInfo(SKILL_TYPE_GUILD, i)
        break
    end
end

Thanks for the tips. Case closed
