Amiibo 註冊

每次使用 amiibo 時，遊戲會紀錄使用了哪個 amiibo 。

• AIDef:Action/CreateEpona 在生成伊波娜後紀錄
• AIDef:AI/WolfLinkAmiibo 在生成林克狼後紀錄
• AIDef:Action/ItemAmiiboSelectDropTable 在「掃描階段」時就會紀錄（請注意此時寶物還沒出現）。

當遊戲試圖紀錄 amiibo 時，會做下面這些事情

• AmiiboMgr 會檢查是不是應該清空「今日使用過的 amiibo 列表」(stored in the AmiiboTouchHistory flag)。
  • 如果遊戲開啟後還沒過 86400 秒（現實一天），則不做任何事。^[check]
  • 否則，AmiiboMgr 會計算 10000 * now.year + 100 * now.month + now.day。如果這個數字不同於 AmiiboLastTouchDate（代表一天過去了），那麼 AmiiboTouchHistory 就會被清空。
• 掃描到的 amiibo 的名字（或其他什麼同樣功能的東西）會被寫進 AmiiboTouchHistory 裡。這個表只會保留最新的 100 個名字。
• 如果這個 amiibo 是「新的」，那麼就把它寫進 AmiiboTouchHistoryTotal 這個表裡。如果那個表裡已經有這個 amiibo 的名字了，那就增加它對應的計數器。這個表只會保留 200 個項目。
• 最後把 AmiiboLastTouchDate 更新成今天的日期。

這兩個表格 AmiiboTouchHistory 跟 AmiiboTouchHistoryTotal 用的格式是 "%s_%d_%d_%d" (amiibo UID 名字, amiibo value 1, amiibo value 2, scan count 掃描次數)

運作邏輯

A SmallHit happens 20% of the time.

If the amiibo has been scanned 0, 1, 2, 3 or 4 times, you'll get a GreatHit 20% of the time. If you didn't get a GreatHit, the game will ensure you get a BigHit.

If the amiibo has been scanned 5 times or more, you'll always get a GreatHit. In this case, the BigHit table is ignored.

For BigHits and GreatHits, the game uses the 'Remain' tables if Find_4Relic_1stClear is set, 'Parasail' if IsGet_PlayerStole2, and 'Normal' otherwise.

The game then determines the number of drops from each table:

• For a GreatHit:
  • GreatHit drops: random number between RepeatNumMin and RepeatNumMax for GreatHit
  • SmallHit drops: same, but for SmallHit (if there is a SmallHit).
  • Normal drops: random number between RepeatNumMin and RepeatNumMax for Normal, minus the GreatHit drop num
• For a BigHit:
  • BigHit drops: random number between RepeatNumMin and RepeatNumMax for BigHit
  • SmallHit drops: same, but for SmallHit (if there is a SmallHit).
  • Normal drops: random number between RepeatNumMin and RepeatNumMax for the Normal table, minus the BigHit drop num

After a GreatHit, the amiibo's scan count for the amiibo is reset to 0 (0x710064AC8C).

Dropped items receive the IsAmiibo actor parameter.

Special cases

Items with the AmiiboArmorItem tag

If the player hasn't received the complete armor set from an amiibo, armor pieces that they have already received will not be spawned.

Items with the Important tag

The IsGet_ flag for Important items must be false; otherwise they will not spawn.

Items with the AmiiboTreasure tag

Items with the AmiiboTreasure tag are spawned inside of a treasure chest (TBox_Field_Iron).

The chest's "SharpWeaponJudgeType" parameter is set to 2, which causes different weapon bonuses and guarantees the weapon will have at least a blue/white modifier.

Exceptions:

• bdrop resource is Actor/DropTable/Item_Amiibo_DropTable_012 (Daruk), drop name starts with "Item_Ore_" and is not Item_Ore_A (Diamond)
• bdrop resource is Actor/DropTable/Item_Amiibo_DropTable_013 (Revali), drop name starts with "Obj_BombArrow"
• bdrop resource is Actor/DropTable/Item_Amiibo_DropTable_015 (Urbosa), drop name starts with "Obj_ElectricArrow"

Items with a name that starts with GameRomHorse

If it is the first time you are scanning an amiibo that can drop horse equipment (if IsAmiiboDrop_GameRomHorseItem isn't set), the game will always spawn GameRomHorseSaddle_01 and GameRomHorseReins_01.

If you have already received those items, they will not spawn consistently anymore (or not at all^[check]).

Items that are marked as amiibo drops

Items that are marked as amiibo drops -- i.e. actors for which the "Amiibo" key exists in the "drops" dictionary in their ActorInfo.product.sbyml entry -- receive an additional DropTable actor parameter. It is set to "Amiibo" for normal drop lists and "Amiibo_After" for Parasail/Remain lists.

Ancient arrows

Obj_AncientArrow_A_01 and Obj_AncientArrow_C_01 can only spawn if you have already received Ancient Arrows at some point (if IsGet_AncientArrow is set).

Divine Beast helms (Armor_181_Head, Armor_182_Head, Armor_183_Head, Armor_184_Head)

When scanning a Champion amiibo, if you've completed any Divine Beast and received a Great Hit, and if you haven't already received the corresponding helm, the chest is guaranteed to contain the Divine Helm.
