7/// Spots are localised structures that spawn in the world. Conceptually, they
8/// fit somewhere between the tree generator and the site generator: an attempt
9/// to marry the simplicity of the former with the capability of the latter.
10/// They are not globally visible to the game: this means that they do not
11/// appear on the map, and cannot interact with rtsim (much).
12///
13/// To add a new spot, one must:
14///
15/// 1. Add a new variant to the [`Spot`] enum.
16/// 2. Add a new entry to [`veloren-world::layer::spot::SpotGenerate::generate`]
17///    that tells the system where to generate your new spot.
18/// 3. Add a new arm to the `match` expression in
19///    [`veloren-world::layer::spot::apply_spots_to`] that tells the generator
20///    how to generate a spot, including the base structure that composes the
21///    spot and the entities that should be spawned there.
22///
23/// Only add spots with randomly spawned NPCs here. Spots that only use
24/// EntitySpawner blocks can be added in assets/world/manifests/spots.ron
