Revision as of 14:37, 11 May 2020
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.
Points
The scaling system is based on a point system. Killing enemies is the only way to receive points.
Whenever an enemy dies, the game increments a flag 'Defeated_{SameGroupActorName}_Num' if all of the following conditions are satisfied:
- The current kill count is < 10.
- The actor does not have the NotCountDefeatedNum flag.
- For Monk Maz Koshia: 'Defeated_Priest_Boss_Normal_Num' is 0.
- For Dark Beast Ganon: It is the first time the boss is beaten. (Ganon's Defeated flag has 1 as the maximum value.)
- 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.
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.
Because enemies have to be killed throughout the main quest and bosses are considered as enemies too, difficulty scaling is unavoidable.
Only the defeated counter flags are stored in the save file. The Ecosystem::LevelSensor
subsystem is responsible for converting these kill counts to points using a configuration file.
The subsystem provides two functions (scaleWeapon
and scaleActor
) that may be called when a weapon or enemy actor is created.
Scaling inhibitors
Both scaling functions will immediately return without doing anything if:
- WorldMgr::sInstance->stageType == 1 (Open World stage)
- and WorldMgr::sInstance->isAocField (current map is Trial of the Sword)
- and WorldMgr::sInstance->disableScaling (set to true when entering Trial of the Sword)
This means that scaling is always disabled in the Trial of the Sword.
Scaling will also be skipped if the current map area is 28. This corresponds to "HateruSea", which is the Eventide Island area.
Weapons
'scaleWeapon' is called (i.e. weapons may be scaled) for a weapon if:
- For standalone weapons: The actor property 'LevelSensorMode' is higher than 1 and it wasn't already picked up.
- For treasure chest drops: If SharpWeaponJudgeType is not 4, when AIDef:AI/TreasureBox initialises the drop actor.
- For Hinox weapons: The flag
{MapName}_Necklace_{i}_{HinoxName}_{ID}
is false. - For other enemy drops: 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')].
Note: Weapons that are bought from a shop cannot receive modifiers because they do not fit into any of the above cases.
Weapon bonuses
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
Weapon bonuses (e.g. Durability Up, Attack Up) are entirely random. Each bonus has equal probability.
Bonus | Available in modifier tiers |
---|---|
Attack up | Blue/White and Yellow |
Durability up | Blue/White and Yellow |
Long throw | Yellow |
Multi-shot burst (bows) | Yellow |
Quick shot (bows) | Yellow |
AddSurfMaster | Yellow |
Shield guard up | Blue/White and Yellow |
Critical Hit | Blue/White |
ZoomRapid | Yellow |
Notes:
- "Critical Hit" can only be selected if weaponCommonSharpWeaponAddCrit is true and if the weapon modifier tier is Blue/White. This means that it becomes impossible to get a weapon with a Critical Hit bonus after enough enemies have been killed.
- 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.
Bonus values
Bonus values (e.g. the durability or attack power increase) are determined from bgparamlist (with a copy of the information in ActorInfoData). Valid ranges and bonuses for each weapon are configured in the WeaponCommon section.
amiibo
Bonus | Value that is used for the bonus effect |
---|---|
None | - |
Attack up | addAtkMax |
Durability up | addLifeMax |
Long throw | addThrowMax |
Multi-shot burst (bows) | 5-shot burst |
Quick shot (bows) | addRapidFireMin |
AddSurfMaster | GlobalParameter::shieldSurfMasterFrictionRatio |
Shield guard up | addGuardMax |
In summary, for amiibo weapons, an attack up always brings it to the greatest possible attack power. No randomness is involved.
Non-amiibo
Bonus | Value that is used for the bonus effect |
---|---|
None | - |
Attack up | Random integer between addAtkMin and addAtkMax |
Durability up | Random integer between addLifeMin and addLifeMax |
Long throw | Random float between addThrowMin and addThrowMax |
Multi-shot burst (bows) | 5-shot burst |
Quick shot (bows) | Random float between addRapidFireMin and addRapidFireMax |
AddSurfMaster | GlobalParameter::shieldSurfMasterFrictionRatio |
Shield guard up | Random integer between addGuardMin and addGuardMax |
In summary, for non-amiibo weapons, an attack up results in a randomized attack power.
Enemies
When loading enemies, the game will always try to scale enemies.
However, the scaling function won't do anything if 'LevelSensorMode' is < 1 and will leave the enemy and any weapons they may hold unscaled.
Note: Enemies that are not in any upgrade list (such as elemental Lizalfos) will not be scaled, but their weapon can still receive upgrades if:
- 'LevelSensorMode' is non zero.
- Weapon point requirements are satisfied
- or the modifier tier is overridden using 'SharpWeaponJudgeType'.
[1.3.0] In Master Mode, all enemies are automatically ranked up one tier by default post scaling, independently of 'LevelSensorMode'. Actors can receive two additional parameters:
Parameter | Default | Description |
---|---|---|
IsHardModeActor | false | Controls whether an enemy only shows up in Master Mode. |
DisableRankUpForHardMode | false | Controls whether the automatic rankup applies to an enemy. |
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).
Properties
LevelSensorMode
This actor property controls whether scaling is enabled for an enemy or weapon. Also applies to any weapons held by an enemy since 'scaleWeapon' is called when an enemy drops their weapon.
Note that this doesn't apply to weapons that are attached to a Hinox's necklace, because Hinoxes use a different underlying enemy actor which overrides the 'on weapon dropped' function and ignores '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
