    }
}

dependencies {
  modApi(include("net.devtech:Attachment:1.3.0"))
}

Entity

public class MyAttachments {
	public static final Identifier ID = new Identifier("mymod:entity_attachment");
	// all settings are optional
	public static final Attachment<Entity, Integer> ENTITY_ATTACHMENT = Attachments.ENTITY.registerAttachment(
			EntityAttachmentSetting.serializer(ID, Codec.INT), // saves the data when the entity is written to the disk
            EntityAttachmentSetting.preserveRespawn(), // copies over the data from the old to new player when they respawn
            EntityAttachmentSetting.sync(ID, TrackedDataHandlerRegistry.INTEGER) // syncs the data to the client
    );
}

World

World attachments are bound to BlockRenderView to allow them to be used in BakedModel rendering

public class MyAttachments {
	public static final Identifier ID = new Identifier("mymod:world_attachment");
	// all settings are optional
	public static final Attachment<BlockRenderView, Integer> WORLD_ATTACHMENT = Attachments.WORLD.registerAttachment(
			WorldAttachmentSetting.serializer(ID, Codec.INT), // saves the data when the world is written to the disk
            WorldAttachmentSetting.sync(ID, TrackedDataHandlerRegistry.INTEGER) // syncs the data to the client
    );
}

Item / NbtCompound

Nbt attachments are bound to NbtCompound to allow them to be used in ItemStacks and regular Nbt.

public class MyAttachments {
	public static final Identifier ID = new Identifier("mymod:item_attachment");
	// all settings are optional, but recommended
	public static final Attachment<NbtCompound, Integer> NBT_ATTACHMENT = Attachments.NBT.registerAttachment(
			NbtAttachmentSetting.serializer(ID, Codec.INT) // saves the data when the nbt tag is written to the disk
    );
	
	public static void set(ItemStack stack, int value) {
		NBT_ATTACHMENT.setValue(stack.getOrCreateNbt(), value);
    }
}

Server

public class MyAttachments {
	public static final Identifier ID = new Identifier("mymod:server_attachment");
	// all settings are optional, but recommended
	public static final Attachment<ServerRef, Integer> NBT_ATTACHMENT = Attachments.SERVER.registerAttachment(
			ServerAttachmentSetting.serializer(ID, Codec.INT), // saves the data when the nbt tag is written to the disk
			ServerAttachmentSetting.sync(ID, TrackedDataHandlerRegistry.INTEGER) // syncs the data to the client
	
	);
	
	public static void set(ServerRef stack, int value) {
		NBT_ATTACHMENT.setValue(stack.getOrCreateNbt(), value);
    }
}
