Module difficulty 

The world difficulty a campaign ships at, and the bodies it stages.

A campaign may declare world.difficulty (easy / normal / hard; peaceful is refused, DW0468). Absent, the engine derives it, and the derivation never picks a difficulty that removes a body the campaign stages: peaceful is the only difficulty that removes any body (see crate::registry::peaceful_despawn), so the derivation is easy when the campaign fields any wave or stages any body of a type peaceful discards, and peaceful otherwise. One function, read by the emitter (server.properties), the combat arithmetic and the DW0469 advisory alike.

Structs

StagedBody

One body a campaign can put into the world, with the entity type it ships as.

Functions

bodies_removed_on_peaceful

The staged bodies the pinned game would discard on peaceful.

derived_difficulty

The difficulty the engine derives for a campaign that declares none: the lowest that keeps every staged body and every declared fight. easy when the campaign fields any wave or stages a body peaceful discards, else peaceful.

effective_difficulty

The difficulty the delve ships at: the declared one, else derived_difficulty.

staged_bodies

Every body the campaign stages whose entity type the author chose, in a fixed order: wave mobs, NPCs, actors (the puppet as it ships — a skinned one is a mannequin — then the twin when the actor is unleashed), volley projectiles.
