Anything that occupies a tile and can be hit: the player and every monster.

One struct covers both. The player has kind: :scriber and is built by scriber/1; monsters have one of the other kinds and are built by spawn/4 from a fixed archetype table. Combat, death and drawing treat the two alike — only who chooses the next action differs, and that is Scriber.Game's concern.

Fields:

• id — unique within a run; the player is always 0
• kind — one of kind/0
• pos — {x, y} on the current level
• hp / max_hp — current and maximum integrity; hp never goes below 0
• power — base damage before the weapon and bonuses in Scriber.Game
• defense — damage subtracted per incoming hit
• speed — tiles moved per turn; an entity strikes at most once a turn however fast
• pace — a turn every pace turns is one the entity acts on; 2 is slow
• art — sprite name in Scriber.Art
• glyph — the same thing for terminals without graphics; kept separately because several kinds may share a glyph while having distinct sprites
• color — {r, g, b} the glyph is drawn in
• shards — paid to the killer when this entity dies
• awake? — whether the entity acts; monsters start asleep, and one that has not seen the player for a while sleeps again
• seen_at — the turn the entity last saw the player, or nil
• goal — where the entity last knew the player, or a noise, to be walked to
• carries — {:fragment, n} when the entity holds a piece of the gate's code, dropped where it dies

Example

monster = Scriber.Entity.spawn(:sentry, 4, {12, 9}, 3)
monster.hp
#=> 24
