Registry system allows the game + COMMENT to enumerate all known types of something, and to assign a unique identifier to each + COMMENT of those. Therefore, registering an object in the registry plays a very important + COMMENT role, and failure to register new instances of registerable object usually results + COMMENT in a bug or even a crash. + COMMENT + COMMENT

Terminologies

+ COMMENT

A registry is an object that holds the mapping between three things: + COMMENT the string ID, the numeric ID, and the registered value. There are many registries + COMMENT for different types of registerable objects, and a registry's type parameter indicates + COMMENT the accepted type. For example, you register your {@link Block} to {@code + COMMENT Registry}. It's important to note that registries themselves are registered + COMMENT in a "registry of registries", {@link #ROOT}. + COMMENT + COMMENT

The string ID, usually just called "ID", is a human-readable + COMMENT {@link Identifier} that uniquely identifies the registered value in a registry. + COMMENT This should stay the same between two game versions, and is usually used for disk + COMMENT storage. + COMMENT + COMMENT

The numeric ID or raw ID is an integer + COMMENT assigned automatically by the registry to each registered value. This is not + COMMENT guaranteed to stay the same between two game versions, and is usually used for + COMMENT networking purposes. + COMMENT + COMMENT

The registered value, often just called "value" in the code, + COMMENT is the value added to the registry. The registry's type parameter determines + COMMENT the type of the registered value. + COMMENT + COMMENT

Each registered value can also be identified with a {@linkplain RegistryKey + COMMENT registry key}. A registry key is a combination of the registry's ID and + COMMENT the registered value's ID. Using a registry key makes the type of the ID's + COMMENT associated value clear, as the type parameter contains the type. + COMMENT + COMMENT

A {@linkplain RegistryEntry registry entry} is an object + COMMENT holding a value that can be registered in a registry. In most cases, the + COMMENT value is already registered in a registry ("reference entry"), hence the name; + COMMENT however, it is possible to create a registry entry by direct reference + COMMENT ("direct entry"). This is useful for data packs, as they can define + COMMENT one-time use values directly without having to register them every time. + COMMENT + COMMENT

A {@link RegistryEntryList registry entry list} is a list + COMMENT of registry entries. This, is either a direct reference to each item, or + COMMENT a reference to a tag. A tag is a way to dynamically + COMMENT define a list of registered values. Anything registered in a registry + COMMENT can be tagged, and each registry holds a list of tags it recognizes. + COMMENT + COMMENT

Static and dynamic registries

+ COMMENT

There are two kinds of registries: static and dynamic. + COMMENT + COMMENT

+ COMMENT + COMMENT

Using Registry

+ COMMENT

Reading Registry

+ COMMENT

A registry is also an {@link IndexedIterable}. Therefore, registries can be + COMMENT iterated using, e.g. {@code for (Block block : Registry.BLOCK)}. + COMMENT + COMMENT

There are several other methods used for reading the contents of the registry: + COMMENT

+ COMMENT + COMMENT

Registering something to Registry

+ COMMENT

The steps for registration are different, depending on whether the registry is static + COMMENT or dynamic. For dynamic registries, data packs can usually be used to register a new + COMMENT value or replace one. For static registries, the game's code must be modified. + COMMENT + COMMENT

Static registries are defined in this class, and unlike the dynamic registries, it + COMMENT cannot be changed after the game initialization. The game enforces this by "freezing" + COMMENT the registry. Attempting to register a value after freezing causes a crash, such as + COMMENT "Registry is already frozen". Modding APIs usually provide a way to bypass this restriction. + COMMENT + COMMENT

To register a value to a dynamic registry, register to a registry found in {@link + COMMENT BuiltinRegistries}. Values registered in those registries are available in all worlds. + COMMENT + COMMENT

In both cases, use {@link #register(Registry, Identifier, Object)} for registering + COMMENT a value to a registry. + COMMENT + COMMENT

Intrusive holders

+ COMMENT

For historical reasons, there are two types of reference registry entries. + COMMENT (This is different from the "direct" and "reference" registry entry types.) + COMMENT + COMMENT

+ COMMENT + COMMENT

When a class whose instances are registered as intrusive holders, such as + COMMENT {@link Block} or {@link Item}, are instantiated without registering, the game + COMMENT crashes with "Some intrusive holders were not added to registry" error message. + COMMENT This includes conditional registration. For example, the code + COMMENT below can cause a crash: + COMMENT + COMMENT 

{@code
+	COMMENT Item myItem = new Item(new Item.Settings());
+	COMMENT if (condition) {
+	COMMENT     Registry.register(Registry.ITEM, new Identifier("example", "bad"), myItem);
+	COMMENT }
+	COMMENT }
+ COMMENT + COMMENT

The correct way is to make the instantiation conditional as well: + COMMENT + COMMENT 

{@code
+	COMMENT if (condition) {
+	COMMENT     Item myItem = new Item(new Item.Settings());
+	COMMENT     Registry.register(Registry.ITEM, new Identifier("example", "bad"), myItem);
+	COMMENT }
