等級系統
Multi-shot burst (bows) 多發弓發數增加
經驗值
等級系統是根據存檔裡的一個「經驗值」系統決定的。只有怪物死掉可以獲得經驗值。（意即解神廟、解任務之類的事情不算。）
每當有敵人死掉，遊戲就會想增加 Defeated_{SameGroupActorName}_Num 這個計數器。 花括號的意思是，如果是波克布林死掉，就會更新波克布林專屬的計數器。 不過，只有下列條件滿足的時候，計數器才會真的增加。
- 計數器本身還不到 10（意思是大部分的怪物只有殺死前十隻才算）
- 死掉的那個敵人沒有 NotCountDefeatedNum flag（意思是某些特殊情況下不算）
- 導師米茲·喬希亞專用的計數器 'Defeated_Priest_Boss_Normal_Num' 是 0（意思是只有殺第一次才算）
- 魔獸加儂也是只有第一次才算
- 厄咒加儂只有在神獸裡打敗的才算，原始遊戲打一次，DLC 跟幻影打一次，總共兩次（在城堡裡打的不算）
需要注意的是只要有任何敵人死掉，不管死法，也不管是不是林克親手殺的，遊戲都會試圖增加計數器。下面會講到哪些情況下不會算。
由於主線劇情會要求玩家殺怪，所以玩家或多或少都會累積經驗值，並且相應地導致等級上升。
遊戲的存檔裡會儲存死了幾隻怪的計數器，有了計數之後 Ecosystem::LevelSensor 這個子系統會用 #Ecosystem::LevelSensor::calculatePoints 計算你的經驗值。不同的怪會給你不同的經驗，表格存在這裡 #Ecosystem::LevelSensor::loadByml.
算出經驗值之後，這個子系統會用這兩個函數 #Ecosystem::LevelSensor::scaleWeapon 跟 #Ecosystem::LevelSensor::scaleActor 來決定敵人跟武器應該分別是什麼等級。
阻止升級的情況
下面這個情況會導致敵人跟武器維持原樣（總而言之就是林克在劍之考驗裡）。
- WorldMgr::sInstance->stageType == 1 (Open World stage)
- 且 WorldMgr::sInstance->isAocField (current map is Trial of the Sword)
- 且 WorldMgr::sInstance->disableScaling (set to true when entering Trial of the Sword)
另一種會跳過升級的情況是 map area 等於 28， 也就是林克位在 "HateruSea"，野外的考驗的塞哈特諾島。
武器
下面這些武器在生成的時候會呼叫它的 'scaleWeapon' 函數
- 單獨存在的武器: The actor property 'LevelSensorMode' is higher than 1 and it wasn't already picked up. 設定上可以升級而且還沒被撿走
- 寶箱裡的武器: If SharpWeaponJudgeType is not 4, when AIDef:AI/TreasureBox initialises the drop actor. 同樣是設定上允許升級
- 西諾克斯脖子上的武器: The flag
{MapName}_Necklace_{i}_{HinoxName}_{ID}is false. - 敵人手上的武器: The flag
{MapName}_WeaponDrop_{ID}is false, and [the actor property 'LevelSensorMode' is higher than 1 or the enemy is a Guardian Scout ('Enemy_Guardian_Mini' 廟裡的守護者)].
註記：從 NPC 那裡拿到的武器（阿卡萊古代研究所、英傑武器）不在上面的列表裡，從而不升級。
武器加成
武器的加成有三個要素。 一是武器本身會被更新成更好的武器（騎士之劍 -> 王族之劍）； 二是武器的攻擊、防禦、耐久等數值擇一增加； 三是增加多少。
加成的方向
要往哪個方向加成（加攻擊還是加耐久？還是別的？）是隨機的， 每個可能的方向有同樣的機率被選到。
| 加成的方向 | Available in modifier tiers |
|---|---|
| Attack up 攻擊力 | Blue/White and Yellow |
| Durability up 耐久度提升 | Blue/White and Yellow |
| Long throw 遠距離投擲 | Yellow |
| Multi-shot burst (bows) 多發弓發數增加 | Yellow |
| Quick shot (bows) 速射 | Yellow |
| AddSurfMaster | Yellow |
| Shield guard up 防禦力 | Blue/White and Yellow |
| Critical Hit 最後爆擊 | Blue/White |
| ZoomRapid | Yellow |
藍標、白標（Blue/White）是比較低階的升級，標記成「某某某提升」。黃標（Yellow）是高階的升級，標記成「某某某大提升」。以攻擊力為例，藍標可能會增加 10~20 的攻擊力（攻擊力提升 +14），而黃標會增加 20~30（攻擊力大提升 +24）。
需注意的是:
- 最後爆擊 "Critical Hit" 只可能在 weaponCommonSharpWeaponAddCrit 是 true 且 加成的 tier 程度是 White/Blue （白色或藍色的「提升」而不是黃色的「大提升」）時出現。 但是隨著經驗值的提升，所有武器的加成都會漸漸變成 Yellow （黃色的「大提升」），所以「最後爆擊」在遊戲後期就不會再出現。
- AddSurfMaster is a bonus that only applies to shields and gives them a lower friction for shield surfing. That bonus type is unused in the game.
加成的程度
武器加成多少（如攻擊力應當提升多少）的數值來源於這個表 bgparamlist (with a copy of the information in ActorInfoData). Valid ranges and bonuses for each weapon are configured in the WeaponCommon section.
amiibo
| 加成的方向 | 加成的程度 |
|---|---|
| None 不加成 | - |
| Attack up 攻擊力 | addAtkMax |
| Durability up 耐久度提升 | addLifeMax |
| Long throw 遠距離投擲 | addThrowMax |
| Multi-shot burst (bows) 多發弓發數增加 | 5-shot burst 五連發 |
| Quick shot (bows) 速射 | addRapidFireMin |
| AddSurfMaster | GlobalParameter::shieldSurfMasterFrictionRatio |
| Shield guard up 防禦力 | addGuardMax |
這段的意思是 amiibo 武器的加成都會是固定的值。譬如說，如果遊戲決定增加攻擊力，而且這個武器的攻擊力最多 +20，那就會 +20。
非 amiibo
| 加成的方向 | 加成的程度 |
|---|---|
| None 不加成 | - |
| Attack up 攻擊力 | addAtkMin 到 addAtkMax 之間的隨機數字 |
| Durability up 耐久度提升 | addLifeMin 到 addLifeMax 之間的隨機數字 |
| Long throw 遠距離投擲 | addThrowMin 到 addThrowMax 之間的隨機數字 |
| Multi-shot burst (bows) 多發弓發數增加 | 5-shot burst 五連發 |
| Quick shot (bows) 速射 | addRapidFireMin 到 addRapidFireMax 之間的隨機數字 |
| AddSurfMaster | GlobalParameter::shieldSurfMasterFrictionRatio |
| Shield guard up 防禦力 | addGuardMin 到 addGuardMax 之間的隨機數字 |
這段的意思是非 amiibo 武器的加成都是隨機的值。譬如說，如果遊戲決定增加攻擊力，而且這個武器的攻擊力從 +10 到 +20 都有可能，那最後生成的武器就會是 10 到 20 之間的隨機數字（應該是均勻分布）。
敵人
遊戲在載入敵人時會根據一定的規則升級敵人。
不過 'LevelSensorMode' < 1 的時候所有敵人（跟武器）都不會升級。
註記：有些敵人本身是無法升級的（例如帶冰、火、電的蜥蜴）， 這僅僅是代表他們自身就已經是最高級了。 而他們手上的武器只要滿足下列條件就可以升級：
- 'LevelSensorMode' 非零且經驗值足夠高
- 或是某個 flag 被強制寫入應該升級 the modifier tier is overridden using 'SharpWeaponJudgeType'.
[1.3.0] 版本加入了大師模式。大師模式裡所有敵人都會先驗地提高一級。這個部分跟 'LevelSensorMode' 造成的升級互不衝突而且可以疊加。更精確的控制是由下面這些參數決定的
| 參數 | 預設值 | Description |
|---|---|---|
| IsHardModeActor | false | 是否只在大師模式出現 |
| DisableRankUpForHardMode | false | 在大師模式裡是否避免升級 |
在大師模式裡，某些敵人的 IsHardModeActor、DisableRankUpForHardMode、LevelSensorMode這三個參數會同時被遊戲設計師手動調整。調整的目的是讓大師模式的後期還是會存在低等級的怪物（例如台地南邊有個紅色小波）。
屬性
LevelSensorMode
這個 actor 屬性決定了一個武器或敵人會不會升級，一個敵人的 LevelSensorMode 屬性同時控制了它手上的武器升不升級。
不過西諾克斯的 LevelSensorMode 屬性並不控制他脖子上的武器如何升級（到頭來是脖子上而不是手上）。總之，西諾克斯用的是另一個機制來決定脖子上的武器如何升級，而且這個機制可以繞過 'LevelSensorMode'。
SharpWeaponJudgeType
This actor property controls the minimum modifier tier that a weapon can receive.
Internally and in assets such as map units, the following values are used for modifiers:
| Value | Description |
|---|---|
| 0 | None: No modifiers. |
| 1 | RandomBlue: Weapon will randomly get at least a blue modifier (with weaponCommonSharpWeaponPer being the probability).
|
| 2 | Blue: Weapon will get at least a blue modifier. |
| 3 | Yellow: Weapon will get at least a yellow modifier. |
| 4 | NoneForced (chests only): Weapon will never spawn with any modifiers. This overrides regular scaling. |
If scaling is enabled, the weapon may receive modifiers from an even higher tier if point requirements are met.
Otherwise, the weapon will get modifiers from exactly the specified tier.
For example, 0 ('None') doesn't mean a weapon will never receive a modifier. It just means that the developers haven't forced the weapon to spawn with a blue/yellow modifier. If scaling requirements are satisfied, the weapon will receive blue or yellow modifiers.
Scaling algorithm
Ecosystem::LevelSensor::loadByml
This function is called by Ecosystem::init from ksys::InitializeApp
Sets up byml structures for reading Ecosystem/LevelSensor.byml.
Ecosystem::LevelSensor::calculatePoints
Called by PlacementMgr when spawning actors.
Calculates weapon and enemy scaling points using a list of flags and configuration values.
All flags that are referenced in the configuration file are of the form Defeated_%s_Num, but technically the configuration format allows for other flags to be specified.
Interestingly, the game calculates a single point value based on the kill counter flags but calculates two separate values for weapons and enemies with two different multipliers. This format makes it possible to easily change the scaling.
float points = 0.0;
for (kill_flag : this->byml["flag"])
int kill_count = GameData::getIntegerFlag(kill_flag["name"]);
points += kill_count * kill_flag["point"];
this->points = points;
this->weapon_points = points * this->byml["setting"].Level2WeaponPower;
this->enemy_points = points * this->byml["setting"].Level2EnemyPower;
In practice, settings have never been modified. 1.5.0 (which will likely be the last game update) still has the same Level2WeaponPower and Level2EnemyPower.
Ecosystem::LevelSensor::scaleWeapon
Called from treasure chest code, enemy actors[check], Ecosystem::LevelSensor::scaleActor
Given a weapon name, its modifier and current point status, this function returns the weapon to actually spawn and the modifier to use (if possible).
If the algorithm fails to find an appropriate weapon that satisfies all conditions (point requirements, weapon series, modifier), the originally specified weapon and modifier will be used directly.
Pseudocode (1.0.0):
bool Ecosystem::LevelSensor::scaleWeapon(const sead::SafeString& weapon_to_look_up,
WeaponModifier required_modifier,
const char** weapon_to_use_name,
WeaponModifier* modifier_to_use,
void* unknown)
{
// some checks using 'unknown' here which seems to be a pointer to the actor
//
for (weapon_table : this->byml["weapon"]) {
// find the first weapon entry for which the player has enough points
// with the specified name and modifier
i = -1;
for (j = 0; j < weapon_table["actors"].size; ++j) {
entry = weapon_table["actors"][j];
float points_for_next_transition = entry["value"];
//
if (this->weapon_points > points_for_next_transition &&
weapon_to_look_up == entry["name"] &&
convert_to_modifier(entry["plus"]) == required_modifier) {
i = j;
break;
}
}
//
if (i == -1)
continue;
//
do {
entry = weapon_table["actors"][i];
//
// not_rank_up means there is no link between weapons;
// this table is just used to look up modifiers.
// so go down the list until there are no more entries for the requested weapon
// or until we reach a modifier that requires more points.
if (weapon_table["not_rank_up"] && entry["name"] != weapon_to_look_up)
break;
//
// otherwise, just go down the list until we reach the end or a weapon which
// requires more points. this will possibly upgrade the weapon (e.g. Knight -> Royal).
if (this->weapon_points <= entry["value"])
break;
//
++i;
} while (i < weapon_table["actors"].size);
//
*weapon_to_use_name = entry["name"];
*modifier_to_use = convert_to_modifier(entry["plus"]);
return true;
}
return false; // cannot scale up
}
Ecosystem::LevelSensor::scaleActor
Analogous to LevelSensor::scaleWeapon.
Pseudocode (1.0.0):
if (actor->params["LevelSensorMode"] < 1)
return false;
//
if (actor_name.contains("Enemy")) {
for (enemy_table : this->byml["enemy"]) {
i = -1;
for (j = 0; j < enemy_table["actors"].size; ++j) {
entry = enemy_table["actors"][j];
if (entry["name"] == actor_name && this->enemy_points > entry["value"]) {
i = j;
break;
}
}
//
if (i == -1)
continue;
//
do {
entry = enemy_table["actors"][i];
if (this->enemy_points <= entry["value"])
break;
++i;
} while (i < enemy_table["actors"].size);
//
*actor_to_use = entry["name"];
return true;
}
return false; // cannot scale up
}
//
if (actor_name.contains("Weapon")) {
weapon_name = actor->getWeaponName();
modifier = actor->params["SharpWeaponJudgeType"];
if (modifier == WeaponModifier::RandomBlue)
modifier = get_random_blue_modifier(actor->getWeaponName());
//
if (scaleWeapon(weapon_name, &weapon_to_use, &modifier_to_use)) {
actor->setProperty("SharpWeaponJudgeType", modifier_to_use);
*actor_to_use = weapon_to_use;
return true;
}
return false; // cannot scale up
}
The Data
To make things easier to understand, here are links to:
This makes it possible to see both the required points for enemy/weapon upgrades, as well as all of the special cases extremely easily.
Ganon Blights
Ganon blights also have varying difficulty but follow a different system. Their health is determined by the base HP (set in bgparamlist) and blight defeat flags.
__int64 SiteBoss::getInitialHP(SiteBoss *this) // 0x71002D01F4
{
const int baseHp = Enemy::getInitialHP(this);
const int halfBaseHp = baseHp >> 1;
const bool dieGanonWind = hasFlag_Die_PGanonWind(0);
const bool dieGanonWater = hasFlag_Die_PGanonWater(0);
const bool dieGanonFire = hasFlag_Die_PGanonFire(0);
const bool dieGanonElectric = hasFlag_Die_PGanonElectric(0);
const int flags = this->siteBossFlags & 0xFFFFFFFC;
int multiplier;
if ( flags == 4 )
multiplier = 3;
else if ( flags == 8 )
multiplier = 4;
else
multiplier = dieGanonFire + dieGanonWind + dieGanonWater + dieGanonElectric;
return baseHp + multiplier * halfBaseHp;
}
Effectively, this means that the first blight Link fights will have 800+0×400 = 800 HP, the second will have 800+1×400 = 1200 HP, the third 800+2×400 = 1600 HP and the last one 800+3×400 = 2000 HP.
Special case 1: Castle Blights
Castle blights have IsRemainBoss set to false in their root AI parameters (see AIDef:AI/SiteBossSpearRoot for example), which sets flag 4.
Thus, blights that are fought in the Castle always have 800+3×400 = 2000 HP regardless of story progression.
If flag 4 is set, the AIDef:Action/SiteBossDie code will NOT increment the "defeated" counter. This means castle blights do not give any scaling points.
Special case 2: DLC2 Blights
Illusory Realm blights possess the EnemySiteBoss_R actor tag. This causes flag 8 to be set. So they will always have 500+4×250 = 1500 HP.
Interestingly, the Windblight AI function relies doesn't check the actor tag but the actor name instead. For flag 8 to be set, the actor name must be Enemy_SiteBoss_Bow_R.
