'''Difficulty scaling''' is a mechanic in ''Breath of the Wild'' that results in enemies and weapons being progressively replaced by more powerful variants during a playthrough.
'''Difficulty scaling''' (nivellement de la difficulté) est un mécanisme dans ''Breath of the Wild'' qui fait que les ennemis et les armes sont progressivement remplacés par des variantes plus puissantes au cours d'une partie de jeu.


== Points ==  
== Points ==  


The scaling system is based on a point system. Killing enemies is the ''only way'' to receive points.
Le système de nivellement se base sur un système de points. Tuer des ennemis est la ''seule manière'' d'en recevoir.


Whenever an enemy dies, the game increments a flag 'Defeated_{SameGroupActorName}_Num' if all of the following conditions are satisfied:
Quand un ennemi meurt, le jeu incrémente un flag 'Defeated_{SameGroupActorName}_Num' si toutes les conditions suivantes sont remplies :
* The current kill count is &#x3C; 10.
* Le nombre de kills est strictement inférieur à 10.
* The actor does not have the NotCountDefeatedNum flag.
* L'acteur n'a pas le flag NotCountDefeatedNum.
* '''For Monk Maz Koshia''': 'Defeated_Priest_Boss_Normal_Num' is 0.
* '''Pour Maz Koshia''' : 'Defeated_Priest_Boss_Normal_Num' est 0.
* '''For Dark Beast Ganon''': It is the first time the boss is beaten. (Ganon's Defeated flag has 1 as the maximum value.)  
* '''Pour Dark Beast Ganon''' : C'est la première fois que le boss final est battu. (Son flag Defeated a pour valeur maximale 1.)  
* '''For Blights''': It is the first time the blight is beaten in the Divine Beast, or in the Illusory Realm. Blights fought in Hyrule Castle do not count.
* '''Pour les Ombres de Ganon''' : C'est la première fois que l'Ombre est battue au sein de la créature divine, ou dans l'univers onirique (DLC2). Les Ombres que vous battez au château d'Hyrule ne comptent pas.
This happens every time ''any'' enemy dies, even if they don't necessarily play a role in the point system (see below) and even if the player is not responsible for their death.
Cela se produit à chaque fois qu'un ennemi ''quelconque'' meurt, même s'il ne joue pas forcément de rôle dans le système de points (voir ci-dessous) et même si le joueur n'est pas responsable pour leur mort.


Because enemies have to be killed throughout the main quest and bosses are considered as enemies too, difficulty scaling is unavoidable.
Vu que des ennemis doivent être tués tout au long de la quête principale et que les boss sont considérés comme des ennemis, le nivellement de la difficulté est inévitable.


Only the defeated counter flags are stored in the save file. The <code>Ecosystem::LevelSensor</code> subsystem is responsible for [[Difficulty scaling#Ecosystem::LevelSensor::calculatePoints|converting these kill counts to points]] using a [[Difficulty scaling#Ecosystem::LevelSensor::loadByml|configuration file]].

Both scaling functions will immediately return without doing anything if:

This means that scaling is always disabled in the Trial of the Sword.

Note: Weapons that are bought from a shop cannot receive modifiers because they do not fit into any of the above cases.
Remarque : les armes achetées dans une boutique ne peuvent pas recevoir de bonus car elles ne rentrent dans aucun des cas mentionnés ci-dessus.


== Weapon bonuses ==  
== Bonus des armes ==  


Weapon scaling results in weapons being replaced by a different weapon (e.g. a Soldier's Bow which becomes a Royal Bow), or weapons gaining a random, bonus stat boost (e.g. Attack Up, Durability Up, etc.). The range of those boosts is also affected by weapon scaling.

=== Bonus types ===
There are two bonus tiers in the game: one for low-level types (which appear in blue/white in the game UI) and another for high-level types (yellow). Those that belong to the Yellow tier are usually superior to the other ones. For instance, ''Attack Up +'' is the superior variant of ''Attack Up'' and it typically grants a higher attack power boost compared to ''Attack Up''.


Weapon bonuses (e.g. Durability Up, Attack Up) are entirely random. Each bonus has equal probability.
=== Types de bonus ===
 
Pour les armes, les bonus (par exemple Durabilité ↑ ou Attaque ↑) sont entièrement aléatoires. Chaque type de bonus est équiprobable.

=== Bonus values ===  
=== Valeurs de bonus ===  


Bonus values (e.g. the durability or attack power increase) are determined from [[ActorParam/GeneralParamList]] (with a copy of the information in [[ActorInfoData]]). Valid ranges and bonuses for each weapon are configured in the WeaponCommon section.

In summary, for amiibo weapons, an attack up always brings it to the greatest possible attack power.
En résumé, pour les armes amiibo, Attaque ↑ donne toujours le pouvoir d'attaque maximum. Il n'y a pas d'aléatoire.
No randomness is involved.

In summary, for non-amiibo weapons, an attack up results in a randomized attack power.
En résumé, pour les armes non issues d'amiibo, Attaque ↑ donne un pouvoir d'attaque aléatoire.

In Master Mode, IsHardModeActor, DisableRankUpForHardMode and LevelSensorMode are combined on some actors to keep low-level enemies in the overworld (e.g. Red Bokoblin south of the Great Plateau).
Dans le Mode Expert, IsHardModeActor, DisableRankUpForHardMode and LevelSensorMode sont combinés sur quelques acteurs pour garder des ennemis de bas niveau dans le monde (par exemple pour garder un Bokoblin rouge au sud du Plateau du Prélude.)

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.

== Ganon Blights ==  
== Ombres de Ganon ==  


Ganon blights also have varying difficulty but follow a different system. Their health is determined by the base HP (set in [[ActorParam/GeneralParamList|GeneralParamList]]) and blight defeat flags.
Les Ombres de Ganon varient elles aussi en difficulté mais suivent un système différent. Leur HP est déterminé par le HP de base (réglé dans [[ActorParam/GeneralParamList|GeneralParamList]]) et les flags de défaite des ombres.

Line 370: Line 373:
}</source>
}</source>


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.
En pratique, cela signifie que la première ombre que Link bat disposera de 800+0×400 = 800 HP, la seconde aura 800+1×400 = 1200 HP, la troisième 800+2×400 = 1600 HP et la dernière 800+3×400 = 2000 HP.


=== Special case 1: Castle Blights ===  
=== Cas spécial 1 : Les ombres du château ===  


Castle blights have <code>IsRemainBoss</code> set to false in their root AI parameters (see [[AIDef:AI/SiteBossSpearRoot]] for example), which sets flag 4.
Les ombres du château d'Hyrule ont <code>IsRemainBoss</code> réglé sur false dans les paramètres de leur AI root (voir [[AIDef:AI/SiteBossSpearRoot]] par exemple), ce qui active le flag 4.


Thus, blights that are fought in the Castle always have 800+3×400 = 2000 HP regardless of story progression.
Ainsi, les ombres combattues au château disposent toujours de 800+3×400 = 2000 HP quelle que soit la progression de l'histoire.


If flag 4 is set, the [[AIDef:Action/SiteBossDie]] code will NOT increment the &#x22;defeated&#x22; counter. This means castle blights do not give any scaling points.
Si le flag 4 est activé, le code [[AIDef:Action/SiteBossDie]] n'incrémenta PAS le compteur Defeated. Cela signifie que les ombres du château ne donnent aucun point de nivellement.


=== Special case 2: DLC2 Blights ===  
=== Cas spécial 2 : Les ombres du DLC2 ===  


Illusory Realm blights possess the <code>EnemySiteBoss_R</code> actor tag. This causes flag 8 to be set. So they will always have 500+4×250 = 1500 HP.
Les ombres dans l'univers onirique possèdent le tag acteur <code>EnemySiteBoss_R</code>. Cela conduit à l'activation du flag 8. Donc celles-ci auront toujours 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 <code>Enemy_SiteBoss_Bow_R</code>.
Fait intéressant, la fonction AI de l'ombre de vent de Ganon (Windblight) ne vérifie pas le tag acteur mais plutôt le nom d'acteur. Pour que le flag 8 soit activé, le nom doit absolument être <code>Enemy_SiteBoss_Bow_R</code>.
