Terminologies
A registry is an object that holds the mapping between three things:
the string ID, the numeric ID, and the registered value. There are many registries
for different types of registerable objects, and a registry's type parameter indicates
the accepted type. For example, you register your Block
to
Registry<Block>
. It's important to note that registries themselves are registered
in a "registry of registries", Registries.ROOT
.
The string ID, usually just called "ID", is a human-readable
Identifier
that uniquely identifies the registered value in a registry.
This should stay the same between two game versions, and is usually used for disk
storage.
The numeric ID or raw ID is an integer assigned automatically by the registry to each registered value. This is not guaranteed to stay the same between two game versions, and is usually used for networking purposes.
The registered value, often just called "value" in the code, is the value added to the registry. The registry's type parameter determines the type of the registered value.
Each registered value can also be identified with a registry key. A registry key is a combination of the registry's ID and the registered value's ID. Using a registry key makes the type of the ID's associated value clear, as the type parameter contains the type.
A registry entry is an object holding a value that can be registered in a registry. In most cases, the value is already registered in a registry ("reference entry"), hence the name; however, it is possible to create a registry entry by direct reference ("direct entry"). This is useful for data packs, as they can define one-time use values directly without having to register them every time.
A registry entry list
is a list
of registry entries. This, is either a direct reference to each item, or
a reference to a tag. A tag is a way to dynamically
define a list of registered values. Anything registered in a registry
can be tagged, and each registry holds a list of tags it recognizes.
Static and dynamic registries
There are two kinds of registries: static and dynamic.
- A static registry is a registry whose values are hard-coded in the game and cannot be added or modified through data packs. Most registries are static. Since they cannot be modified (without mods), it is a singleton, and exists in this class. During the game bootstrap, vanilla objects are registered, after which the registry gets frozen to prohibit further changes.
- A dynamic registry is a registry whose values can be
added or replaced through data packs. A dynamic registry is bound to a server,
and multiple registries for the same type of registerable object can exist during
the lifetime of the game. When a player joins, the server sends the contents of
the dynamic registry manager to the client, but only "network serializable"
registries are sent. To access a dynamic registry, first get an instance of the
dynamic registry manager, then call the
DynamicRegistryManager.get(net.minecraft.registry.RegistryKey<? extends net.minecraft.registry.Registry<? extends E>>)
method.
Using Registry
Reading Registry
A registry is also an IndexedIterable
. Therefore, registries can be
iterated using, e.g. for (Block block : Registries.BLOCK)
.
There are several other methods used for reading the contents of the registry:
entryOf(net.minecraft.registry.RegistryKey<T>)
orgetEntry(RegistryKey)
for getting the registry entry from the key.get(Identifier)
orget(RegistryKey)
for getting the registered value from the ID or the registry key.getId(Object)
for getting the ID of a registered value.getEntry(int)
for getting the registry entry from the raw ID.getEntryList(net.minecraft.registry.tag.TagKey<T>)
anditerateEntries(net.minecraft.registry.tag.TagKey<T>)
for getting the contents of a tag,streamTags()
for streaming all tags of a registry.
Registering something to Registry
The steps for registration are different, depending on whether the registry is static or dynamic. For dynamic registries, data packs can usually be used to register a new value or replace one. For static registries, the game's code must be modified.
Static registries are defined in Registries
, and unlike the dynamic registries, it
cannot be changed after the game initialization. The game enforces this by "freezing"
the registry. Attempting to register a value after freezing causes a crash, such as
"Registry is already frozen". Modding APIs usually provide a way to bypass this restriction.
Use register(Registry, Identifier, Object)
for registering a value to a registry.
Intrusive holders
For historical reasons, there are two types of reference registry entries. (This is different from the "direct" and "reference" registry entry types.)
- Intrusive holders are registry entries tied to a specific
registerable object at instantiation time. When instantiating those, it promises
that the object is later registered - which, if broken, will result in a crash.
This is used for
Registries.BLOCK
,Registries.ITEM
,Registries.FLUID
,Registries.ENTITY_TYPE
, andRegistries.GAME_EVENT
registries. - Standalone holders are registry entries that are not intrusive. There is no restriction on instantiation.
When a class whose instances are registered as intrusive holders, such as
Block
or Item
, are instantiated
without registering, the game crashes with "Some intrusive holders were not added to
registry" error message. This includes conditional registration.
For example, the code below can cause a crash:
Item myItem = new Item(new Item.Settings());
if (condition) {
Registry.register(Registries.ITEM, new Identifier("example", "bad"), myItem);
}
The correct way is to make the instantiation conditional as well:
if (condition) {
Item myItem = new Item(new Item.Settings());
Registry.register(Registries.ITEM, new Identifier("example", "bad"), myItem);
}
