Id for Components?

[Tonaion02]

I can't understand if each Component has an Id in bevy, some sort of integer identifier for component types.

Yes https://docs.rs/bevy/latest/bevy/ecs/component/struct.ComponentId.html

Yes, you can obtain it with World::component_id. Note that you can have multiple components types of the same rust type, or components made of non-rust types. The API for creating such component types is World::init_component_with_descriptor, but it should only really be used for modding.
