Cooking

Concepts

Boost

Cooked items sometimes receive bonuses (improved effect duration, potency, health recovery, etc.). This random process is internally called a "boost". When this happens, the player is said to have gotten a "critical success".

The probability of getting a boost is calculated based on what ingredients the player is using.

However, boosts are guaranteed during a blood moon. More exactly:

• The current day must be a "Bloody Day" (see WorldMgr for more information).
• The "blood moon time range progress" must be strictly greater than 0.1%.
  • This value starts increasing linearly from 0% at 23:30 and reaches 100% at 00:00, then starts decreasing and reaches 0% at 00:15.
  • Effectively, this means the time range is roughly 23:30-00:15.

Tag

Tags (in the context of the cooking subsystem) are exactly the same thing as regular actor tags (see bxml). However, they are stored as CRC32 hashes in the configuration file.

CookData.byml

This resource is found in Bootup.pack.

Its canonical resource path is "Cooking/CookData.byml".

CookData.byml is the configuration file for the CookingMgr (which implements cooking functionality).

System

The System header, located at the bottom of CookData.byml, contains parameters that define how the cooking system functions.

CEI

CEI contains the parameters for each effect type available when cooking.

Key	Name (unofficial)	Description
BT	Base Time	Minimum amount of time a recipe effect will be active for, before additions/multipliers from ingredients.
MR	Material Rate	Multiplier on the EffectLevel of ingredients used to obtain the final effect amount.
Ma	Maximum	Maximum effect level. For stamina, in 1/5s of a wheel. For hearts, in 1/4s of a heart. The executable enforces a hard cap of 3 for all effect types that are not stamina or hearts.
Mi	Minimum	Minimum effect level. For stamina, in 1/5s of a wheel. For hearts, in 1/4s of a heart. (The executable ignores this parameter for all effect types.)
SSA	unknown
T	Type	Effect Type, as un/signed hash of string. Valid types are hashes of the following: LifeRecover, LifeMaxUp, ResistHot, ResistCold, ResistElectric, AllSpeed, AttackUp, DefenseUp, Quietness, Fireproof. (GutsRecover and GutsMaxUp are the two unlisted types, but their unhashed string values are currently unknown)

NMMR

Unofficial name: Next Milestone Material Rate

An independent parameter in System, NMMR is used to determine what the final effect level is for any given recipe. The ingredients' EffectLevels are added together, then multiplied by the effect type's MR. The result is compared to the NMMR array. If the result is:

• greater than the first number, the recipe is given effect level 1
• greater than the second number and Ma >= 2, it is given effect level 2
• greater than the third number and Ma >= 3, it is given effect level 3

A recipe can only have one effect. If two effects in a single recipe both exceed the first number in the NMMR array, the game discards all of them.

Though there are five numbers in the NMMR array, only the first three are used, as the game hard-caps the Maximum for all effect types that use NMMR to 3.
