== amiibo registering ==

amiibo are registered<ref>0x710064B564 on Switch 1.5.0</ref> every time an amiibo is used.
* [[AIDef:Action/CreateEpona]] does so after Epona has been spawned.
* [[AIDef:AI/WolfLinkAmiibo]] does it after spawning Wolf Link.
* [[AIDef:Action/ItemAmiiboSelectDropTable]] registers an amiibo as soon as it is scanned, even before spawning the drops.

Whenever an amiibo is registered:
*AmiiboMgr determines if it should reset its daily amiibo use history (stored in the AmiiboTouchHistory flag)<ref>0x710064B3C8</ref>.
**If less than 86400 seconds (1 day) have elapsed since the game was launched, don't do anything.{{check}}
**AmiiboMgr then computes <code>10000 * now.year + 100 * now.month + now.day</code>. If the value is different from AmiiboLastTouchDate (which would mean that a day has elapsed), the AmiiboTouchHistory array is cleared.
*An entry for the scanned amiibo is inserted into AmiiboTouchHistory. Only the last 100 entries are kept.
*For a first time scan, a new entry is inserted into AmiiboTouchHistoryTotal (only the last 200 entries are kept). Otherwise, the scan count is incremented by updating the existing entry.
*Finally, AmiiboLastTouchDate is set to the current date.

The format for AmiiboTouchHistory and AmiiboTouchHistoryTotal entries is "%s_%d_%d_%d" (amiibo UID, amiibo value 1, amiibo value 2, scan count)

== Logic ==

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<ref>[[AIDef:Action/ItemAmiiboCreateFromDropTable]]</ref>:
* 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 [[difficulty scaling#Weapon bonuses|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]] 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<ref>If the corresponding IsGet flag is false</ref>, the chest is guaranteed to contain the Divine Helm.

=== Code ===

Unless otherwise indicated, all member function names below are unofficial. (Only the class name is official.)
