Amiibo 注册

每次使用 amiibo 时，游戏会纪录使用了哪个 amiibo 。

• AIDef:Action/CreateEpona 在生成伊波娜后纪录
• AIDef:AI/WolfLinkAmiibo 在生成林克狼后纪录
• AIDef:Action/ItemAmiiboSelectDropTable 在“扫描阶段”时就会纪录（请注意此时宝物还没出现）。

当游戏试图纪录 amiibo 时，会做下面这些事情

• AmiiboMgr 会检查是不是应该清空“今日使用过的 amiibo 列表”(stored in the AmiiboTouchHistory flag)。
  • 如果游戏开启后还没过 86400 秒（现实一天），则不做任何事。^[check]
  • 否则，AmiiboMgr 会计算 10000 * now.year + 100 * now.month + now.day。如果这个数字不同于 AmiiboLastTouchDate（代表一天过去了），那么 AmiiboTouchHistory 就会被清空。
• 扫描到的 amiibo 的名字（和其他任天堂认为有必要纪录的东西）会被写进 AmiiboTouchHistory 里。这个表只会保留最新的 100 个名字。
• 如果这个 amiibo 是“新的”，那么就把它写进 AmiiboTouchHistoryTotal 这个表里。如果那个表里已经有这个 amiibo 的名字了，那就增加它对应的计数器。这个表只会保留 200 个项目。
• 最后把 AmiiboLastTouchDate 更新成今天的日期。

这两个表格 AmiiboTouchHistory 跟 AmiiboTouchHistoryTotal 用的格式是 "%s_%d_%d_%d" (amiibo UID 名字, amiibo value 1, amiibo value 2, scan count 扫描次数)

运作逻辑

有 20% 的几率出现 SmallHit。

如果这是第 0, 1, 2, 3, 或 4 次扫描这个 amiibo，游戏有 20% 的几率给你 GreatHit（姑且译作“特奖”）。如果遇到另外 80%，游戏会给你 BigHit（姑且译作“头奖”）。

如果这个 amiibo 已经连续扫 5 次还没出过特奖的话，第六次开始就会保证是特奖。

开头奖跟特奖的时候，游戏会检查玩家的进度，如果 Find_4Relic_1stClear 为真（打完一只神兽），游戏会使用 'Remain' 这个表决定掉落物。若否，游戏会检查 IsGet_PlayerStole2（拿到滑翔伞），为真则使用 'Parasail' 这个表，否则只用 'Normal' 这个表。

决定好使用哪个表格后，游戏会决定应该掉落多少东西：

• GreatHit 特奖的情况：
  • 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
• BigHit 头奖的情况:
  • 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

开出特奖后，本 amiibo 的扫描次数会重设为 0 (0x710064AC8C).

Dropped items receive the IsAmiibo actor parameter.

特例

标有 AmiiboArmorItem 的掉落物

（属于衣服类的掉落物） 如果玩家还没拿过一整套（头、身、脚）的话，已经拿过的部分不会再出现。

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.
