Is the fishing rod's hook an entity? Can I summon it? Or can I put something like @e[type=InsertFishingHook'sNameHere] in a command block?
The fishing rod bobber is an entity, but it's a bit of a weird one.
As it's never saved to the world (they disappear on relog), it has no id. This means you cannot summon it, nor select it with
You can still select it though, with the selector
@e[name=unknown], using which you can do anything you could do with a regular entity.
