modifyLoot

@Deprecated
public static List<ItemStack> modifyLoot(List<ItemStack> list,
 LootContext context)

Deprecated.

Use modifyLoot(ResourceLocation, ObjectArrayList, LootContext) instead.

All loot table drops should be passed to this function so that mod added effects (e.g. smelting enchantments) can be processed.

Parameters:

list - The loot generated

context - The loot context that generated that loot

Returns:

The modified list

Implementation Note:

This method will use the unknown loot table marker when redirecting.

public static it.unimi.dsi.fastutil.objects.ObjectArrayList<ItemStack> modifyLoot(ResourceLocation lootTableId,
 it.unimi.dsi.fastutil.objects.ObjectArrayList<ItemStack> generatedLoot,

Handles the modification of loot table drops via the registered Global Loot Modifiers, so that custom effects can be processed.

All loot-table generated loot should be passed to this function.

Parameters:

lootTableId - The ID of the loot table currently being queried

generatedLoot - The loot generated by the loot table

context - The loot context that generated the loot, unmodified

Returns:

The modified list of drops

API Note:

The given context will be modified by this method to also store the ID of the loot table being queried.

shouldSuppressEnderManAnger

public static boolean shouldSuppressEnderManAnger(EnderMan enderMan,
 Player player,
 ItemStack mask)

prefixNamespace

public static String prefixNamespace(ResourceLocation registryKey)

This method is used to prefix the path, where elements of the associated registry are stored, with their namespace, if it is not minecraft

This rules conflicts with equal paths out. If for example the mod fancy_cheese adds a registry named cheeses, but the mod awesome_cheese also adds a registry called cheeses, they are going to have the same path cheeses, just with different namespaces. If additional_cheese wants to add additional cheese to awesome_cheese, but not fancy_cheese, it can not differentiate both. Both paths will look like data/additional_cheese/cheeses.

The fix, which is applied here prefixes the path of the registry with the namespace, so fancy_cheese's registry stores its elements in data/<namespace>/fancy_cheese/cheeses and awesome_cheese's registry stores its elements in data/namespace/awesome_cheese/cheeses

Parameters:

registryKey - key of the registry

Returns:

path of the registry key. Prefixed with the namespace if it is not "minecraft"

canUseEntitySelectors

public static boolean canUseEntitySelectors(SharedSuggestionProvider provider)

wrapRegistryLookup

@Internal
public static <T> HolderLookup.RegistryLookup<T> wrapRegistryLookup(HolderLookup.RegistryLookup<T> lookup)

onLivingBreathe

public static void onLivingBreathe(LivingEntity entity,
 int consumeAirAmount,
 int refillAirAmount)

Handles living entities being underwater. This fires the LivingBreatheEvent and if the entity's air supply is less than or equal to zero also the LivingDrownEvent. Additionally, when the entity is underwater it will dismount if IEntityExtension.canBeRiddenUnderFluidType(FluidType, Entity) returns false.

Parameters:

entity - The living entity which is currently updated

consumeAirAmount - The amount of air to consume when the entity is unable to breathe

refillAirAmount - The amount of air to refill when the entity is able to breathe

Implementation Note:

This method needs to closely replicate the logic found right after the call site in LivingEntity.baseTick() as it overrides it.
