Dummy Components

Dummy components are useless components that are only used for data storage. Dummy components don't do anything on their own. They need to be paired with secondary mechanics to have any function. Dummy components are useful because they allow us to store information on the entities, and use the information to drive graphics/gameplay mechanics.

Good examples are variant and mark_variant. These components can be set with an Integer value. In the vanilla resource pack, this Integer is used to pick the textures for the Cat, and Horse. Another good example is is_tamed, which is used by the Horse to handle whether he is ridable or not.

Dummy components are good because they allow us to save data about our entity, and then query this data using Molang.

Integer Dummies

Integer dummies are set with an integer value, which allows you to store numbers, such as 1, 10, or 1423. These integers can be read using queries. Integer dummies are the most useful.

Bit Dummies

Bit dummies store a single bit of information. Namely True or False. For example is_tamed, which is either False (not added to the entity), or True (Added to the entity).
